Abstract

Objective Building self-esteem in overweight adolescents is key to long-term weight manage-

ment yet self-esteem is rarely a key outcome of adolescent weight management interventions

This systematic review investigates the impact of multicomponent weight management interven-

tions on self-esteem in overweight and obese adolescents Method Six databases were searched

in December 2014 Eligible studies met the following criteria (1) randomized controlled trial (2)

overweight or obese participants (3) adolescents (10ndash19 years) (4) multicomponent weight man-

agement intervention (5) reported self-esteem and weight changes Results Thirteen studies with

1157 overweight or obese adolescents aged 10ndash19 years were included Meta-analyses showed

no significant change in self-esteem (027 [004 059]) but body mass index z-score reduced

following intervention (017 [022 011]) Conclusion The lack of change in self-esteem sug-

gests weight loss alone is insufficient to improve self-esteem Multicomponent weight manage-

ment interventions require a specific focus on self-esteem to improve this outcome in overweight

and obese adolescents

Introduction

In the United States gt20 of adolescents (12ndash19years) are classified as obese (Ogden Carroll Kit ampFlegal 2014) and at an increased risk of experiencingthe associated physiological comorbidities Howeverthe psychosocial comorbidities such as reduced self-esteem have a more immediate impact and are oftendrivers for overweight or obese adolescents to seektreatment (Lobstein Baur amp Uauy 2004)Adolescence is a critical period of physical and psy-chological development that occurs between 10 and19 years of age (World Health Organization 2014)

during which young people are at an increased risk ofexperiencing low self-esteem (Mission Australia2012) This risk is further exacerbated if they are

obese (Griffiths Parsons amp Hill 2010 McClureTanksi Kingsbury Gerrard amp Sargent 2010Sanders Han Baker amp Cobley 2015)

Global self-esteem is the sum of onersquos perceivedability or competence in comparison with onersquos aspir-

ations in domains of importance (eg physical ap-pearance cognitive ability) Low self-esteem is causedwhen there is a discrepancy between onersquos perceivedlevel of competence and aspirations in one or more

domains that are of importance to the individual(Harter 1993) Self-esteem can fluctuate greatly dur-

ing adolescence and there is an increased risk of self-esteem being low particularly from the age of 13 years

(French Story amp Perry 1995 Strauss 2000)During adolescence self-esteem plays an important

role in metal health and development (McClure et al2010) Low self-esteem in adolescents particularly

overweight adolescents has been linked to disturbedeating and dieting behaviors a preoccupation with

body weight and shape an inactive lifestyle andpoorer performance in education and developmental

tasks (Latzer amp Stein 2013) Low self-esteem hasbeen hypothesized both as a contributing factor and

consequence of obesity (French et al 1995) Increasedself-esteem purportedly leads to better weight out-

comes in the long term (Elfhag amp Rossner 2005French et al 1995 Roberts 2006) Therefore weight-

management interventions for adolescents should aimto improve self-esteem

Multicomponent weight management interventions(MWMI) with behavioral dietary and physical activity

components are best practice for achieving successfulweight loss in overweight and obese adolescents (Kohn

et al 2006 Luttikhuis et al 2009 National Health andMedical Research Council 2013 National Institutes for

Health and Care Excellence 2013) However their im-pact on self-esteem is still not well reported (Luttikhuis

et al 2009) despite this being a recommendation froma previous review of the effect of weight management

programs on pediatric self-esteem (Lowry Sallinen ampJanicke 2007)

This systematic review and meta-analysis ofrandomized controlled trials (RCTs) examines the ef-

fect of MWMIs on self-esteem in overweight andobese adolescents A secondary outcome is the impact

of MWMIs on weight loss and whether this is associ-ated with improvements in self-esteem This review

provides an update of the literature since the reviewby Lowry et al (2007) and focuses specifically on (1)

adolescents an at-risk group for experiencing lowself-esteem and (2) MWMIs the most effective

method for weight management in children and ado-lescents (Luttikhuis et al 2009)

Methods

This review was registered with PROSPERO

International prospective register of systematic re-views (registration number CRD42015016889) and is

reported according to the Preferred Reporting Itemsfor Systematic reviews and Meta-Analysis (PRISMA)

Statement (see Table S1 in the supplement forPRISMA Checklist Moher et al 2015)

Literature SearchA literature search was conducted in December 2014in the Scopus MEDLINE PsychInfo CochraneLibrary Cumulative Index to Nursing and AlliedHealth Literature and Embase databases Searchterms were used to describe the population (eg over-weight youth) intervention (eg lifestyle health edu-cation nutrition physical activity) control (eg usualcare) outcomes (eg esteem body mass index) andstudy design (eg RCT controlled trial) Studies werelimited to English and humans where databases pro-vided that option (see Table S2 in the supplement forfull search strategy) The criteria for inclusion in thisreview were (1) RCT (2) overweight or obese (3)adolescent (10ndash19 years World Health Organization2014) (4) a MWMI (behavioral dietary and physicalactivity components) (5) reported self-esteem andweight changes Body mass index (BMI) z-score wasthe preferential choice for ascertaining weight statusbut if not reported other weight outcomes werecollected

Search results were imported into EndNote X72Version 1702 (Thomson Reuters New York CityUSA) Duplicate articles were manually removed bythe lead author (MM) Throughout the title and ab-stract screening two authors (MM and AD) inde-pendently excluded papers if they did not report theresults of an RCT if the intervention did not includeall three behavioral dietary and physical activitycomponents or if there was no measure of self-esteemIncluded papers were cross-checked and discrepancieswere resolved by the third author (MB) Papers thatincluded healthy weight individuals or individuals out-side the adolescent age range were included at full-paper screening and the authors were contacted to re-trieve results specific to the population of interestThese papers were subsequently excluded if authorsdid not respond within 1 month of initial contact orwere unable to provide the requested data All fullpapers were independently screened by two authors(MM and AD) and were cross-checked with anydisagreements resolved by the third author (MB)

Data ExtractionData extraction was conducted using the NationalHealth and Medical Research Council of Australiadata extraction tool for RCT and cohort studies Datawere independently extracted by two researchers(MM and AD) and included outcome measuresintervention and control conditions study designpopulation characteristics and results The two sets ofextracted data were compared to ensure complete andcorrect interpretation Any disagreements were settledby the MB Data that were missing from the includedstudies such as additional results and detailed meth-odology were obtained from separate publications

Risk of BiasThe American Dietetic Association Quality CriteriaChecklist was used to assess the quality of the papers

(Academy of Nutrition and Dietetics 2012) Criteriawere independently tested by two researchers (MM

and AD) to determine study quality including ran-domization research question participant selection

and comparability blinding outcome measures stat-istical analysis and potential for bias from funding

Studies were designated a positive neutral or negativerating Publication bias was assessed through visual in-

terpretation of funnel plots created using RevMan 53(Cochrane Informatics amp Knowledge Management

Department 2014 see Figure S1)

Statistical AnalysisCohenrsquos d effect sizes were calculated for weight andself-esteem outcomes to allow for comparison of re-

sults across studies Positive effect sizes indicated theoutcome had improved that is increased self-esteem

or decreased weight (02frac14 small effect05frac14me-dium effect08frac14 large effect) Where an effect size

could not be calculated the reported significance ofresults was assessed Following tests for normality ef-

fect sizes for self-esteem and weight changes were as-sessed for correlation using the Pearson Correlation

test and the coefficient of determination (R2)Meta-analyses were performed to compare the

change in the intervention and control groups forboth self-esteem and BMI z-score using Stata

Statistical Software (Release 13 2013 Texas USA)Only studies that reported the mean (SD) change in

self-esteem or BMI z-score and compared the inter-vention with a no-treatment control group were

included in the meta-analyses If data were not origin-ally reported in this format results were requested

from the authors for inclusion in this review To ac-count for the different tools used to measure self-

esteem outcomes a standard mean difference (SMD)was calculated from the Cohenrsquos d effect size for each

study Studies that reported a weight outcome otherthan BMI z-score were excluded from the meta-

analysis Weighted mean difference was calculated forBMI z-score for the meta-analysis All meta-analyses

were carried out using random effects analysisSensitivity analyses were not performed as only a

small number of studies were included and they wereall of neutral or positive quality

Results

Database searches identified 4707 original papersFollowing title and abstract screening 115 full-textarticles were retrieved and assessed for eligibilityThirteen papers met the review criteria including 2studies that were reviewed by Lowry et al (2007) and11 studies published since Seven studies wereincluded in the meta-analyses (Figure 1)

Description of Included StudiesThe included studies involved between 32 and 208male andor female participants aged 10ndash19 yearswho were overweight or obese (BMI 85th percent-ile) Owing to the limited number of studies that ex-clusively examined the overweight adolescentpopulation studies with mixed populations wereincluded (Croker et al 2012 Danielsen NordhusJulıusson Maelighle amp Pallesen 2013 Lochrie et al2013 Lubans et al 2012 Morgan Saunders ampLubans 2012 Neumark-Sztainer et al 2010 Sacheret al 2010) However only data relating to the popu-lation of interest are reported

Interventions ranged from seven weeks up to a yearin length Only results taken immediately postinterven-tion were assessed in this review For studies thatincluded an intense treatment phase followed by a main-tenance phase the results taken immediately after the in-tense treatment phase have been used as theldquopostinterventionrdquo results (Brennan Wilks WalkleyFraser amp Greenway 2012 Daley Copeland WrightRoalfe amp Wales 2006 Neumark-Sztainer et al 2010)One exception to this was the study by NguyenShrewsbury et al (2012) that had an additional outcomemeasurement at 12 months half way through the main-tenance phase For this study the 12-month measureshave been used as the ldquopostinterventionrdquo results as thiswas the first time point that reported separate results forthe intervention and control groups

All interventions included dietary physical activityand behavioral strategies (Table I) For the purpose ofthis review all groups that received a treatment that metthe review criteria for a MWMI were considered ldquointer-vention groupsrdquo hence there are a greater number ofintervention than control groups In all studies theintervention and control groups were considered com-parable at baseline for the outcomes of interest

Risk of BiasIncluded studies were assessed against 10 criteria andstudy quality was generally high (Table I) Four criteriahad to be met for a study to receive a positive quality rat-ing The remaining six criteria contributed to the overallrating but were not compulsory for a positive rating tobe assigned All 14 studies in this review met the criteriafor a clearly stated research question clearly definedvalid and reliable outcome measures and low risk of bias

owing to funding or sponsorship Four studies weredowngraded to a neutral quality rating for not meetingthe criteria (1) selection of participants free from bias(Danielsen et al 2013 Morgan et al 2012) (2) studygroups comparable at baseline (Neumark-Sztainer et al2010) or (3) intervention and comparison conditionsdescribed in detail (Mellin Slinkard amp Irwin 1987Morgan et al 2012) Other criteria that were not met byall studies but did not result in the assignment of any neu-tral quality ratings included appropriate statistical

analysis handling of withdrawals described and use

blinding to prevent bias Funnel plot analysis (Figure S1)did not suggest publication bias however should be inter-

preted with caution owing to the small number of studies

The Impact of Weight Management on Self-Esteem 385

self-esteem was observed following four MWMIsacross three studies (Croker et al 2012 Danielsenet al 2013 Nguyen Shrewsbury et al 2012) Fivestudies showed no effect on adolescent self-esteem fol-lowing MWMI (Brennan et al 2012 DeBar et al2012 Lochrie et al 2013 Lubans et al 2012Neumark-Sztainer et al 2010) No positive effects onself-esteem were observed in any of the controlgroups One wait-listed control group (Croker et al2012) showed a small negative effect on self-esteem

Mixed results were also observed in the studies forwhich an effect size could not be calculatedImprovements in adolescent self-esteem were observedfollowing MWMIs by Daley et al (2006) Mellin et al(1987) Sacher et al (2010) and Wadden et al(1990) However only Daley et al (2006) reportedthat this change was different to that observed in thecontrol group No changes in self-esteem were de-tected following intervention by Morgan et al (2012)although a significant decline in self-esteem wasobserved in the wait-listed control group who receivedthe normal school curriculum throughout the studyperiod

Multicomponent Weight ManagementInterventions Improve Weight Outcomes inAdolescentsOf the 13 included studies there were 14 groups whoreceived a MWMI and 11 no-treatment controlgroups Of these effect sizes were able to be calculatedfor nine intervention groups and seven control groups(Table III) Seven intervention groups had small to me-dium positive effects indicating successful weight loss(Brennan et al 2012 Croker et al 2012 Danielsenet al 2013 DeBar et al 2012 Lochrie et al 2013Lubans et al 2012 Nguyen Shrewsbury et al2012) and two intervention groups had no effect(Neumark-Sztainer et al 2010 Nguyen Shrewsburyet al 2012) All seven control groups showed no ef-fect on weight

Of the studies for which effect size could not be cal-culated the results were similar Mellin et al (1987)Morgan et al (2012) Sacher et al (2010) andWadden et al (1990) all observed significant weightloss following intervention Morgan et al (2012) andSacher et al (2010) also showed that these changeswere significantly different to changes observed in thecontrol groups No studies observed significant weightchange in the control groups

Correlation Between Self-Esteem Improvementand Weight Loss Effect SizesThere is a strong (rfrac14 641 R2frac140410) positive linearrelationship between effect sizes for self-esteem im-provement and weight loss across all intervention andcontrol groups (pfrac14 008)T

Quantitative Data AnalysisDifferences between intervention and control groupsfor change in self-esteem are presented in Figure 2aThis analysis included seven intervention groups(nfrac14 191) and seven control groups (nfrac14 132) with

interventions or intensive treatment phases rangingfrom 9 weeks to 6 months in duration A moderatelevel of the variation across studies was owing to het-erogeneity (I2frac14464 Higgins Thompson Deeksamp Altman 2003) The overall summary effect showed

no effect on self-esteem as a result of interventionSMD of 027 (95 confidence interval 004 059)zfrac14 169 and pfrac14 092 However all studies exceptone favored the intervention for improvements in self-esteem

The difference between intervention and controlgroups for change in BMI z-score is illustrated inFigure 2b This analysis included five interventiongroups (nfrac14 135) and five control groups (nfrac14 82) withinterventions ranging from 9 weeks to 6 months induration Heterogeneity in this sample was low(I2frac14177 Higgins et al 2003) and the overall sum-mary effect was 017 (022 011) BMI z-scorepoints (zfrac14613 and plt 001) indicating statisticallysignificant weight loss following MWMI

Discussion

The purpose of this review was to examine the effectof MWMIs on self-esteem in overweight and obeseadolescents Increased self-esteem is proposed as a keyfactor for maintaining long-term weight management(Elfhag amp Rossner 2005 French et al 1995Roberts 2006) A secondary outcome of this reviewwas to examine the impact of MWMIs on weight lossand whether this was associated with improvements inself-esteem

The meta-analysis showed no difference in self-esteem between the intervention and control groupsHowever six of the seven studies in the meta-analysisfavored the intervention over control for improve-ments in self-esteem and four of the six studies notincluded in the meta-analysis found significant im-provements in self-esteem following intervention Thelatter of these findings are similar to those of an earlierreview (Lowry et al 2007) that showed improve-ments in self-esteem following weight managementinterventions in a pediatric population particularlywhen certain intervention features were presentSimilarly a number of intervention features that con-tributed to an increased likelihood of improving self-esteem were identified in this review

Improvements in self-esteem regardless of weightloss have been demonstrated in children who tookpart in weight management interventions thatincluded a focus on building self-esteem and it is rec-ommended that this be a focus of all pediatric weightmanagement interventions (Lowry et al 2007) Yetthe majority of studies identified in this review did notinclude building self-esteem as a key aspect of theirintervention Nguyen Shrewsbury et al (2012)described the greatest focus on self-esteem (one75-min group session focused on building self-esteem)and also resulted in the largest treatment effect (057)and a significant improvement in self-esteem (NguyenShrewsbury et al 2012) A focus on similar topics

such as body image social support and managing bul-lying may also contribute to improvements in self-esteem (Croker et al 2012 Pierce amp Wardle 1997Tiggemann 2005) however these findings highlightthe lack of uptake of these recommendations

Among overweight and obese youth reductions inself-esteem are often observed in domains of physicalappearance and physical ability (Franklin DenyerSteinbeck Caterson amp Hill 2006 French et al1995 Latzer amp Stein 2013 Lowry et al 2007)Particularly for adolescent girls body image is a keyconcern (Cave Fildes Luckett amp Wearring 2015)and comprises a large portion of global self-esteem(Lowry et al 2007 Pesa Syre amp Jones 2000)However weight loss and associated changes in phys-ical appearance do not necessarily reflect improve-ments in self-esteem (Lowry et al 2007) Changes inbody-esteem often occur more rapidly than changes inglobal self-esteem as a result of weight management(Lowry et al 2007) This may explain the lack ofchange observed in global self-esteem in this meta-analysis and highlights the need to also include body-esteem (or physical self-esteem) as a focus and out-come of weight management interventions foradolescents

Parental involvement in adolescent weight manage-ment interventions is a critical component for success-ful weight loss and may also be important forimproving self-esteem (Lowry et al 2007) Weight-related teasing from family is shown to be negativelyassociated with self-esteem in overweight adolescentswhereas family connectedness was positively associ-ated with adolescent self-esteem (Fulkerson StraussNeumark-Sztainer Story amp Boutelle 2007) The in-clusion of parents in weight management interventionsfosters a safer and more encouraging home environ-ment for the adolescent (Lowry et al 2007) which isassociated with increased self-esteem in nonover-weight children (Marx amp Neumark-Sztainer 2005)All studies in the present review baring one includedparents in the intervention Parental involvementshould continue to be a key component of weightmanagement interventions to ensure a supportivehome environment for the adolescent to help fosterpositive self-esteem

Weight management interventions that used agroup setting to target self-esteem have shown im-provements in self-esteem without significant weightchange (Lowry et al 2007 Sherman AlexanderGomez Kim amp Marole 1992) The ability of the peergroup setting to provide opportunities for bondingsupport feelings of belonging development of peer-based skills and positive peer exchanges is key toincreasing self-esteem (Lowry et al 2007) The im-portance of this element is being acknowledged in the

field with all the studies in this review baring twousing group sessions in their intervention

Measures of self-esteem are self-reported and there-fore subjective Responses to questionnaires are likelyto be influenced by individual (eg age gender) andenvironmental (eg cultural group socioeconomicstatus) factors (Khanlou 2004) Changes followinginterventions may represent genuine long-termchanges in self-esteem or may be due to short-termfluctuations in self-esteem in response to specificevents (eg winning a sporting event or performanceon a test at school) (Kernis 1993) While validatedtools were used to measure self-esteem in all studies itwas difficult to conclude whether outcomes were en-tirely dependent on the intervention without inclusionof a no-treatment control group

The variety of self-esteem assessment tools also addsto the difficulty of interpretation Across the 13 studies inthis review five different tools were used with differentquestions and different scales Even within tools therewere different scales used to report the results (RosenbergSelf-esteem Scale) and different versions of the same ques-tionnaire (Harterrsquos Self-perception Profile for ChildrenHarterrsquos Self-perception Profile for Adolescents) HarterrsquosSelf-Perception Profile (Harterrsquos Self-perception Profilefor Adolescents for adolescents) which measures ninesubscales of self-esteem including physical self-esteem issuggested as the most appropriate measure for adolescentself-esteem (Lowry et al 2007) It was also the mostcommonly used tool among papers included in this re-view While Cohenrsquos d effect sizes were used to stand-ardize results in this review the consistent use of one toolwould provide the ability to compare raw self-esteemscores and create a stronger analysis in the future

Results from this review support evidence thatMWMIs induce weight loss in overweight and obeseadolescents (Hoelscher Kirk Ritchie ampCunningham-Sabo 2013 Kelly amp Melnyk 2008Luttikhuis et al 2009) The change in BMI z-score inthe present meta-analysis (017 [022 011]) wassimilar to the clinically meaningful weight loss re-ported in the 2009 Cochrane Review in children 12years at 6 months follow up from a lifestyle weightmanagement intervention (014 [017 012])(Luttikhuis et al 2009) Jelalian Mehlenbeck Lloyd-Richardson Birmaher and Wing (2006) and WalkerGately Bewick and Hill (2003) have demonstratedassociations between weight loss and increased self-esteem in overweight and obese adolescents after at-tending a weight-management intervention Similarlyin the present review a strong positive relationship be-tween treatment effects for weight loss and improve-ment in self-esteem was identified However itremains unclear whether the improvement in self-esteem was as a result of successful weight loss orwhether it was a contributing factor toward successful

weight loss Nonetheless building self-esteem shouldbe a key focus of MWMIs as improved self-esteem ap-

pears to be linked to enhanced weight lossA key strength of this review was that all included

studies had strong designs and presented level II evi-dence (Coleman et al 2009) However to further elu-

cidate the role of self-esteem in adolescent weightmanagement future research should consider power-

ing studies to detect changes in psychosocial as well asphysiological outcomes Only one study in this reviewwas powered to detect a change in psychosocial out-

comes (Daley et al 2006) which may explain thelack of significant results observed for self-esteem

Additionally a large number of included studies didnot describe their method of handling withdrawals or

use blinding to prevent the introduction of bias Toimprove confidence in the effectiveness of MWMIs

and reduce the risk of bias future studies should bedesigned with concealed allocation and document andreport in detail the flow of participants

Identification of intervention components that im-

prove self-esteem is important for future weight man-agement intervention design Included interventionswere heterogeneous offering different levels of diet-

ary physical activity and behavioral interventionwhich may have collectively or individually influenced

the results Inconsistent reporting of intervention andcomparator conditions make it difficult to elucidate

the components that contributed to improvements inself-esteem Future studies should report intervention

and comparator procedures in adequate detail so thatsuccessful components can be identified and repli-cated These limitations highlight areas for improve-

ment to develop best-practice guidelines forundertaking and evaluating MWMIs in adolescents to

enhance self-esteem

Conclusion

Overweight and obese adolescents experience low

self-esteem largely owing to poor body image yetthis meta-analysis found no improvement in self-esteem even with significant weight loss Although it

was noted that interventions that had larger effects onself-esteem also had larger effects on weight loss The

incorporation of intervention components that wereidentified to contribute to improvements in self-

esteem may assist future weight management interven-tions to improve the self-esteem of overweight and

obese adolescents Furthermore a consistent measureof self-esteem would enable easier interpretation ofself-esteem scores and comparison of results across

studies to improve our understanding of the relation-ship between self-esteem and weight management in

adolescents

Page 2: Systematic Review and Meta-Analysis: The Impact of ...people.uncw.edu/hakanr/documents/weightlossandselfesteem.pdf · (French, Story, & Perry, 1995; Strauss, 2000). During adolescence,

domains that are of importance to the individual(Harter 1993) Self-esteem can fluctuate greatly dur-

ing adolescence and there is an increased risk of self-esteem being low particularly from the age of 13 years

(French Story amp Perry 1995 Strauss 2000)During adolescence self-esteem plays an important

role in metal health and development (McClure et al2010) Low self-esteem in adolescents particularly

overweight adolescents has been linked to disturbedeating and dieting behaviors a preoccupation with

body weight and shape an inactive lifestyle andpoorer performance in education and developmental

tasks (Latzer amp Stein 2013) Low self-esteem hasbeen hypothesized both as a contributing factor and

consequence of obesity (French et al 1995) Increasedself-esteem purportedly leads to better weight out-

comes in the long term (Elfhag amp Rossner 2005French et al 1995 Roberts 2006) Therefore weight-

management interventions for adolescents should aimto improve self-esteem

Multicomponent weight management interventions(MWMI) with behavioral dietary and physical activity

components are best practice for achieving successfulweight loss in overweight and obese adolescents (Kohn

et al 2006 Luttikhuis et al 2009 National Health andMedical Research Council 2013 National Institutes for

Health and Care Excellence 2013) However their im-pact on self-esteem is still not well reported (Luttikhuis

et al 2009) despite this being a recommendation froma previous review of the effect of weight management

programs on pediatric self-esteem (Lowry Sallinen ampJanicke 2007)

This systematic review and meta-analysis ofrandomized controlled trials (RCTs) examines the ef-

fect of MWMIs on self-esteem in overweight andobese adolescents A secondary outcome is the impact

of MWMIs on weight loss and whether this is associ-ated with improvements in self-esteem This review

provides an update of the literature since the reviewby Lowry et al (2007) and focuses specifically on (1)

adolescents an at-risk group for experiencing lowself-esteem and (2) MWMIs the most effective

method for weight management in children and ado-lescents (Luttikhuis et al 2009)

Methods

This review was registered with PROSPERO

International prospective register of systematic re-views (registration number CRD42015016889) and is

reported according to the Preferred Reporting Itemsfor Systematic reviews and Meta-Analysis (PRISMA)

Statement (see Table S1 in the supplement forPRISMA Checklist Moher et al 2015)

Literature SearchA literature search was conducted in December 2014in the Scopus MEDLINE PsychInfo CochraneLibrary Cumulative Index to Nursing and AlliedHealth Literature and Embase databases Searchterms were used to describe the population (eg over-weight youth) intervention (eg lifestyle health edu-cation nutrition physical activity) control (eg usualcare) outcomes (eg esteem body mass index) andstudy design (eg RCT controlled trial) Studies werelimited to English and humans where databases pro-vided that option (see Table S2 in the supplement forfull search strategy) The criteria for inclusion in thisreview were (1) RCT (2) overweight or obese (3)adolescent (10ndash19 years World Health Organization2014) (4) a MWMI (behavioral dietary and physicalactivity components) (5) reported self-esteem andweight changes Body mass index (BMI) z-score wasthe preferential choice for ascertaining weight statusbut if not reported other weight outcomes werecollected

Search results were imported into EndNote X72Version 1702 (Thomson Reuters New York CityUSA) Duplicate articles were manually removed bythe lead author (MM) Throughout the title and ab-stract screening two authors (MM and AD) inde-pendently excluded papers if they did not report theresults of an RCT if the intervention did not includeall three behavioral dietary and physical activitycomponents or if there was no measure of self-esteemIncluded papers were cross-checked and discrepancieswere resolved by the third author (MB) Papers thatincluded healthy weight individuals or individuals out-side the adolescent age range were included at full-paper screening and the authors were contacted to re-trieve results specific to the population of interestThese papers were subsequently excluded if authorsdid not respond within 1 month of initial contact orwere unable to provide the requested data All fullpapers were independently screened by two authors(MM and AD) and were cross-checked with anydisagreements resolved by the third author (MB)

Data ExtractionData extraction was conducted using the NationalHealth and Medical Research Council of Australiadata extraction tool for RCT and cohort studies Datawere independently extracted by two researchers(MM and AD) and included outcome measuresintervention and control conditions study designpopulation characteristics and results The two sets ofextracted data were compared to ensure complete andcorrect interpretation Any disagreements were settledby the MB Data that were missing from the includedstudies such as additional results and detailed meth-odology were obtained from separate publications

Risk of BiasThe American Dietetic Association Quality CriteriaChecklist was used to assess the quality of the papers

(Academy of Nutrition and Dietetics 2012) Criteriawere independently tested by two researchers (MM

and AD) to determine study quality including ran-domization research question participant selection

and comparability blinding outcome measures stat-istical analysis and potential for bias from funding

Studies were designated a positive neutral or negativerating Publication bias was assessed through visual in-

terpretation of funnel plots created using RevMan 53(Cochrane Informatics amp Knowledge Management

Department 2014 see Figure S1)

Statistical AnalysisCohenrsquos d effect sizes were calculated for weight andself-esteem outcomes to allow for comparison of re-

sults across studies Positive effect sizes indicated theoutcome had improved that is increased self-esteem

or decreased weight (02frac14 small effect05frac14me-dium effect08frac14 large effect) Where an effect size

could not be calculated the reported significance ofresults was assessed Following tests for normality ef-

fect sizes for self-esteem and weight changes were as-sessed for correlation using the Pearson Correlation

test and the coefficient of determination (R2)Meta-analyses were performed to compare the

change in the intervention and control groups forboth self-esteem and BMI z-score using Stata

Statistical Software (Release 13 2013 Texas USA)Only studies that reported the mean (SD) change in

self-esteem or BMI z-score and compared the inter-vention with a no-treatment control group were

included in the meta-analyses If data were not origin-ally reported in this format results were requested

from the authors for inclusion in this review To ac-count for the different tools used to measure self-

esteem outcomes a standard mean difference (SMD)was calculated from the Cohenrsquos d effect size for each

study Studies that reported a weight outcome otherthan BMI z-score were excluded from the meta-

analysis Weighted mean difference was calculated forBMI z-score for the meta-analysis All meta-analyses

were carried out using random effects analysisSensitivity analyses were not performed as only a

small number of studies were included and they wereall of neutral or positive quality

Results

Database searches identified 4707 original papersFollowing title and abstract screening 115 full-textarticles were retrieved and assessed for eligibilityThirteen papers met the review criteria including 2studies that were reviewed by Lowry et al (2007) and11 studies published since Seven studies wereincluded in the meta-analyses (Figure 1)

Description of Included StudiesThe included studies involved between 32 and 208male andor female participants aged 10ndash19 yearswho were overweight or obese (BMI 85th percent-ile) Owing to the limited number of studies that ex-clusively examined the overweight adolescentpopulation studies with mixed populations wereincluded (Croker et al 2012 Danielsen NordhusJulıusson Maelighle amp Pallesen 2013 Lochrie et al2013 Lubans et al 2012 Morgan Saunders ampLubans 2012 Neumark-Sztainer et al 2010 Sacheret al 2010) However only data relating to the popu-lation of interest are reported

Interventions ranged from seven weeks up to a yearin length Only results taken immediately postinterven-tion were assessed in this review For studies thatincluded an intense treatment phase followed by a main-tenance phase the results taken immediately after the in-tense treatment phase have been used as theldquopostinterventionrdquo results (Brennan Wilks WalkleyFraser amp Greenway 2012 Daley Copeland WrightRoalfe amp Wales 2006 Neumark-Sztainer et al 2010)One exception to this was the study by NguyenShrewsbury et al (2012) that had an additional outcomemeasurement at 12 months half way through the main-tenance phase For this study the 12-month measureshave been used as the ldquopostinterventionrdquo results as thiswas the first time point that reported separate results forthe intervention and control groups

All interventions included dietary physical activityand behavioral strategies (Table I) For the purpose ofthis review all groups that received a treatment that metthe review criteria for a MWMI were considered ldquointer-vention groupsrdquo hence there are a greater number ofintervention than control groups In all studies theintervention and control groups were considered com-parable at baseline for the outcomes of interest

Risk of BiasIncluded studies were assessed against 10 criteria andstudy quality was generally high (Table I) Four criteriahad to be met for a study to receive a positive quality rat-ing The remaining six criteria contributed to the overallrating but were not compulsory for a positive rating tobe assigned All 14 studies in this review met the criteriafor a clearly stated research question clearly definedvalid and reliable outcome measures and low risk of bias

owing to funding or sponsorship Four studies weredowngraded to a neutral quality rating for not meetingthe criteria (1) selection of participants free from bias(Danielsen et al 2013 Morgan et al 2012) (2) studygroups comparable at baseline (Neumark-Sztainer et al2010) or (3) intervention and comparison conditionsdescribed in detail (Mellin Slinkard amp Irwin 1987Morgan et al 2012) Other criteria that were not met byall studies but did not result in the assignment of any neu-tral quality ratings included appropriate statistical

analysis handling of withdrawals described and use

blinding to prevent bias Funnel plot analysis (Figure S1)did not suggest publication bias however should be inter-

preted with caution owing to the small number of studies

self-esteem was observed following four MWMIsacross three studies (Croker et al 2012 Danielsenet al 2013 Nguyen Shrewsbury et al 2012) Fivestudies showed no effect on adolescent self-esteem fol-lowing MWMI (Brennan et al 2012 DeBar et al2012 Lochrie et al 2013 Lubans et al 2012Neumark-Sztainer et al 2010) No positive effects onself-esteem were observed in any of the controlgroups One wait-listed control group (Croker et al2012) showed a small negative effect on self-esteem

Mixed results were also observed in the studies forwhich an effect size could not be calculatedImprovements in adolescent self-esteem were observedfollowing MWMIs by Daley et al (2006) Mellin et al(1987) Sacher et al (2010) and Wadden et al(1990) However only Daley et al (2006) reportedthat this change was different to that observed in thecontrol group No changes in self-esteem were de-tected following intervention by Morgan et al (2012)although a significant decline in self-esteem wasobserved in the wait-listed control group who receivedthe normal school curriculum throughout the studyperiod

Multicomponent Weight ManagementInterventions Improve Weight Outcomes inAdolescentsOf the 13 included studies there were 14 groups whoreceived a MWMI and 11 no-treatment controlgroups Of these effect sizes were able to be calculatedfor nine intervention groups and seven control groups(Table III) Seven intervention groups had small to me-dium positive effects indicating successful weight loss(Brennan et al 2012 Croker et al 2012 Danielsenet al 2013 DeBar et al 2012 Lochrie et al 2013Lubans et al 2012 Nguyen Shrewsbury et al2012) and two intervention groups had no effect(Neumark-Sztainer et al 2010 Nguyen Shrewsburyet al 2012) All seven control groups showed no ef-fect on weight

Of the studies for which effect size could not be cal-culated the results were similar Mellin et al (1987)Morgan et al (2012) Sacher et al (2010) andWadden et al (1990) all observed significant weightloss following intervention Morgan et al (2012) andSacher et al (2010) also showed that these changeswere significantly different to changes observed in thecontrol groups No studies observed significant weightchange in the control groups

Correlation Between Self-Esteem Improvementand Weight Loss Effect SizesThere is a strong (rfrac14 641 R2frac140410) positive linearrelationship between effect sizes for self-esteem im-provement and weight loss across all intervention andcontrol groups (pfrac14 008)T

Quantitative Data AnalysisDifferences between intervention and control groupsfor change in self-esteem are presented in Figure 2aThis analysis included seven intervention groups(nfrac14 191) and seven control groups (nfrac14 132) with

interventions or intensive treatment phases rangingfrom 9 weeks to 6 months in duration A moderatelevel of the variation across studies was owing to het-erogeneity (I2frac14464 Higgins Thompson Deeksamp Altman 2003) The overall summary effect showed

no effect on self-esteem as a result of interventionSMD of 027 (95 confidence interval 004 059)zfrac14 169 and pfrac14 092 However all studies exceptone favored the intervention for improvements in self-esteem

The difference between intervention and controlgroups for change in BMI z-score is illustrated inFigure 2b This analysis included five interventiongroups (nfrac14 135) and five control groups (nfrac14 82) withinterventions ranging from 9 weeks to 6 months induration Heterogeneity in this sample was low(I2frac14177 Higgins et al 2003) and the overall sum-mary effect was 017 (022 011) BMI z-scorepoints (zfrac14613 and plt 001) indicating statisticallysignificant weight loss following MWMI

Discussion

The purpose of this review was to examine the effectof MWMIs on self-esteem in overweight and obeseadolescents Increased self-esteem is proposed as a keyfactor for maintaining long-term weight management(Elfhag amp Rossner 2005 French et al 1995Roberts 2006) A secondary outcome of this reviewwas to examine the impact of MWMIs on weight lossand whether this was associated with improvements inself-esteem

The meta-analysis showed no difference in self-esteem between the intervention and control groupsHowever six of the seven studies in the meta-analysisfavored the intervention over control for improve-ments in self-esteem and four of the six studies notincluded in the meta-analysis found significant im-provements in self-esteem following intervention Thelatter of these findings are similar to those of an earlierreview (Lowry et al 2007) that showed improve-ments in self-esteem following weight managementinterventions in a pediatric population particularlywhen certain intervention features were presentSimilarly a number of intervention features that con-tributed to an increased likelihood of improving self-esteem were identified in this review

Improvements in self-esteem regardless of weightloss have been demonstrated in children who tookpart in weight management interventions thatincluded a focus on building self-esteem and it is rec-ommended that this be a focus of all pediatric weightmanagement interventions (Lowry et al 2007) Yetthe majority of studies identified in this review did notinclude building self-esteem as a key aspect of theirintervention Nguyen Shrewsbury et al (2012)described the greatest focus on self-esteem (one75-min group session focused on building self-esteem)and also resulted in the largest treatment effect (057)and a significant improvement in self-esteem (NguyenShrewsbury et al 2012) A focus on similar topics

such as body image social support and managing bul-lying may also contribute to improvements in self-esteem (Croker et al 2012 Pierce amp Wardle 1997Tiggemann 2005) however these findings highlightthe lack of uptake of these recommendations

Among overweight and obese youth reductions inself-esteem are often observed in domains of physicalappearance and physical ability (Franklin DenyerSteinbeck Caterson amp Hill 2006 French et al1995 Latzer amp Stein 2013 Lowry et al 2007)Particularly for adolescent girls body image is a keyconcern (Cave Fildes Luckett amp Wearring 2015)and comprises a large portion of global self-esteem(Lowry et al 2007 Pesa Syre amp Jones 2000)However weight loss and associated changes in phys-ical appearance do not necessarily reflect improve-ments in self-esteem (Lowry et al 2007) Changes inbody-esteem often occur more rapidly than changes inglobal self-esteem as a result of weight management(Lowry et al 2007) This may explain the lack ofchange observed in global self-esteem in this meta-analysis and highlights the need to also include body-esteem (or physical self-esteem) as a focus and out-come of weight management interventions foradolescents

Parental involvement in adolescent weight manage-ment interventions is a critical component for success-ful weight loss and may also be important forimproving self-esteem (Lowry et al 2007) Weight-related teasing from family is shown to be negativelyassociated with self-esteem in overweight adolescentswhereas family connectedness was positively associ-ated with adolescent self-esteem (Fulkerson StraussNeumark-Sztainer Story amp Boutelle 2007) The in-clusion of parents in weight management interventionsfosters a safer and more encouraging home environ-ment for the adolescent (Lowry et al 2007) which isassociated with increased self-esteem in nonover-weight children (Marx amp Neumark-Sztainer 2005)All studies in the present review baring one includedparents in the intervention Parental involvementshould continue to be a key component of weightmanagement interventions to ensure a supportivehome environment for the adolescent to help fosterpositive self-esteem

Weight management interventions that used agroup setting to target self-esteem have shown im-provements in self-esteem without significant weightchange (Lowry et al 2007 Sherman AlexanderGomez Kim amp Marole 1992) The ability of the peergroup setting to provide opportunities for bondingsupport feelings of belonging development of peer-based skills and positive peer exchanges is key toincreasing self-esteem (Lowry et al 2007) The im-portance of this element is being acknowledged in the

field with all the studies in this review baring twousing group sessions in their intervention

Measures of self-esteem are self-reported and there-fore subjective Responses to questionnaires are likelyto be influenced by individual (eg age gender) andenvironmental (eg cultural group socioeconomicstatus) factors (Khanlou 2004) Changes followinginterventions may represent genuine long-termchanges in self-esteem or may be due to short-termfluctuations in self-esteem in response to specificevents (eg winning a sporting event or performanceon a test at school) (Kernis 1993) While validatedtools were used to measure self-esteem in all studies itwas difficult to conclude whether outcomes were en-tirely dependent on the intervention without inclusionof a no-treatment control group

The variety of self-esteem assessment tools also addsto the difficulty of interpretation Across the 13 studies inthis review five different tools were used with differentquestions and different scales Even within tools therewere different scales used to report the results (RosenbergSelf-esteem Scale) and different versions of the same ques-tionnaire (Harterrsquos Self-perception Profile for ChildrenHarterrsquos Self-perception Profile for Adolescents) HarterrsquosSelf-Perception Profile (Harterrsquos Self-perception Profilefor Adolescents for adolescents) which measures ninesubscales of self-esteem including physical self-esteem issuggested as the most appropriate measure for adolescentself-esteem (Lowry et al 2007) It was also the mostcommonly used tool among papers included in this re-view While Cohenrsquos d effect sizes were used to stand-ardize results in this review the consistent use of one toolwould provide the ability to compare raw self-esteemscores and create a stronger analysis in the future

Results from this review support evidence thatMWMIs induce weight loss in overweight and obeseadolescents (Hoelscher Kirk Ritchie ampCunningham-Sabo 2013 Kelly amp Melnyk 2008Luttikhuis et al 2009) The change in BMI z-score inthe present meta-analysis (017 [022 011]) wassimilar to the clinically meaningful weight loss re-ported in the 2009 Cochrane Review in children 12years at 6 months follow up from a lifestyle weightmanagement intervention (014 [017 012])(Luttikhuis et al 2009) Jelalian Mehlenbeck Lloyd-Richardson Birmaher and Wing (2006) and WalkerGately Bewick and Hill (2003) have demonstratedassociations between weight loss and increased self-esteem in overweight and obese adolescents after at-tending a weight-management intervention Similarlyin the present review a strong positive relationship be-tween treatment effects for weight loss and improve-ment in self-esteem was identified However itremains unclear whether the improvement in self-esteem was as a result of successful weight loss orwhether it was a contributing factor toward successful

weight loss Nonetheless building self-esteem shouldbe a key focus of MWMIs as improved self-esteem ap-

pears to be linked to enhanced weight lossA key strength of this review was that all included

studies had strong designs and presented level II evi-dence (Coleman et al 2009) However to further elu-

cidate the role of self-esteem in adolescent weightmanagement future research should consider power-

ing studies to detect changes in psychosocial as well asphysiological outcomes Only one study in this reviewwas powered to detect a change in psychosocial out-

comes (Daley et al 2006) which may explain thelack of significant results observed for self-esteem

Additionally a large number of included studies didnot describe their method of handling withdrawals or

use blinding to prevent the introduction of bias Toimprove confidence in the effectiveness of MWMIs

and reduce the risk of bias future studies should bedesigned with concealed allocation and document andreport in detail the flow of participants

Identification of intervention components that im-

prove self-esteem is important for future weight man-agement intervention design Included interventionswere heterogeneous offering different levels of diet-

ary physical activity and behavioral interventionwhich may have collectively or individually influenced

the results Inconsistent reporting of intervention andcomparator conditions make it difficult to elucidate

the components that contributed to improvements inself-esteem Future studies should report intervention

and comparator procedures in adequate detail so thatsuccessful components can be identified and repli-cated These limitations highlight areas for improve-

ment to develop best-practice guidelines forundertaking and evaluating MWMIs in adolescents to

enhance self-esteem

Conclusion

Overweight and obese adolescents experience low

self-esteem largely owing to poor body image yetthis meta-analysis found no improvement in self-esteem even with significant weight loss Although it

was noted that interventions that had larger effects onself-esteem also had larger effects on weight loss The

incorporation of intervention components that wereidentified to contribute to improvements in self-

esteem may assist future weight management interven-tions to improve the self-esteem of overweight and

obese adolescents Furthermore a consistent measureof self-esteem would enable easier interpretation ofself-esteem scores and comparison of results across

studies to improve our understanding of the relation-ship between self-esteem and weight management in

adolescents

Risk of BiasThe American Dietetic Association Quality CriteriaChecklist was used to assess the quality of the papers

(Academy of Nutrition and Dietetics 2012) Criteriawere independently tested by two researchers (MM

and AD) to determine study quality including ran-domization research question participant selection

and comparability blinding outcome measures stat-istical analysis and potential for bias from funding

Studies were designated a positive neutral or negativerating Publication bias was assessed through visual in-

terpretation of funnel plots created using RevMan 53(Cochrane Informatics amp Knowledge Management

Department 2014 see Figure S1)

Statistical AnalysisCohenrsquos d effect sizes were calculated for weight andself-esteem outcomes to allow for comparison of re-

sults across studies Positive effect sizes indicated theoutcome had improved that is increased self-esteem

or decreased weight (02frac14 small effect05frac14me-dium effect08frac14 large effect) Where an effect size

could not be calculated the reported significance ofresults was assessed Following tests for normality ef-

fect sizes for self-esteem and weight changes were as-sessed for correlation using the Pearson Correlation

test and the coefficient of determination (R2)Meta-analyses were performed to compare the

change in the intervention and control groups forboth self-esteem and BMI z-score using Stata

Statistical Software (Release 13 2013 Texas USA)Only studies that reported the mean (SD) change in

self-esteem or BMI z-score and compared the inter-vention with a no-treatment control group were

included in the meta-analyses If data were not origin-ally reported in this format results were requested

from the authors for inclusion in this review To ac-count for the different tools used to measure self-

esteem outcomes a standard mean difference (SMD)was calculated from the Cohenrsquos d effect size for each

study Studies that reported a weight outcome otherthan BMI z-score were excluded from the meta-

analysis Weighted mean difference was calculated forBMI z-score for the meta-analysis All meta-analyses

were carried out using random effects analysisSensitivity analyses were not performed as only a

small number of studies were included and they wereall of neutral or positive quality

Results

Database searches identified 4707 original papersFollowing title and abstract screening 115 full-textarticles were retrieved and assessed for eligibilityThirteen papers met the review criteria including 2studies that were reviewed by Lowry et al (2007) and11 studies published since Seven studies wereincluded in the meta-analyses (Figure 1)

Description of Included StudiesThe included studies involved between 32 and 208male andor female participants aged 10ndash19 yearswho were overweight or obese (BMI 85th percent-ile) Owing to the limited number of studies that ex-clusively examined the overweight adolescentpopulation studies with mixed populations wereincluded (Croker et al 2012 Danielsen NordhusJulıusson Maelighle amp Pallesen 2013 Lochrie et al2013 Lubans et al 2012 Morgan Saunders ampLubans 2012 Neumark-Sztainer et al 2010 Sacheret al 2010) However only data relating to the popu-lation of interest are reported

Interventions ranged from seven weeks up to a yearin length Only results taken immediately postinterven-tion were assessed in this review For studies thatincluded an intense treatment phase followed by a main-tenance phase the results taken immediately after the in-tense treatment phase have been used as theldquopostinterventionrdquo results (Brennan Wilks WalkleyFraser amp Greenway 2012 Daley Copeland WrightRoalfe amp Wales 2006 Neumark-Sztainer et al 2010)One exception to this was the study by NguyenShrewsbury et al (2012) that had an additional outcomemeasurement at 12 months half way through the main-tenance phase For this study the 12-month measureshave been used as the ldquopostinterventionrdquo results as thiswas the first time point that reported separate results forthe intervention and control groups

All interventions included dietary physical activityand behavioral strategies (Table I) For the purpose ofthis review all groups that received a treatment that metthe review criteria for a MWMI were considered ldquointer-vention groupsrdquo hence there are a greater number ofintervention than control groups In all studies theintervention and control groups were considered com-parable at baseline for the outcomes of interest

Risk of BiasIncluded studies were assessed against 10 criteria andstudy quality was generally high (Table I) Four criteriahad to be met for a study to receive a positive quality rat-ing The remaining six criteria contributed to the overallrating but were not compulsory for a positive rating tobe assigned All 14 studies in this review met the criteriafor a clearly stated research question clearly definedvalid and reliable outcome measures and low risk of bias

owing to funding or sponsorship Four studies weredowngraded to a neutral quality rating for not meetingthe criteria (1) selection of participants free from bias(Danielsen et al 2013 Morgan et al 2012) (2) studygroups comparable at baseline (Neumark-Sztainer et al2010) or (3) intervention and comparison conditionsdescribed in detail (Mellin Slinkard amp Irwin 1987Morgan et al 2012) Other criteria that were not met byall studies but did not result in the assignment of any neu-tral quality ratings included appropriate statistical

analysis handling of withdrawals described and use

blinding to prevent bias Funnel plot analysis (Figure S1)did not suggest publication bias however should be inter-

preted with caution owing to the small number of studies

self-esteem was observed following four MWMIsacross three studies (Croker et al 2012 Danielsenet al 2013 Nguyen Shrewsbury et al 2012) Fivestudies showed no effect on adolescent self-esteem fol-lowing MWMI (Brennan et al 2012 DeBar et al2012 Lochrie et al 2013 Lubans et al 2012Neumark-Sztainer et al 2010) No positive effects onself-esteem were observed in any of the controlgroups One wait-listed control group (Croker et al2012) showed a small negative effect on self-esteem

Mixed results were also observed in the studies forwhich an effect size could not be calculatedImprovements in adolescent self-esteem were observedfollowing MWMIs by Daley et al (2006) Mellin et al(1987) Sacher et al (2010) and Wadden et al(1990) However only Daley et al (2006) reportedthat this change was different to that observed in thecontrol group No changes in self-esteem were de-tected following intervention by Morgan et al (2012)although a significant decline in self-esteem wasobserved in the wait-listed control group who receivedthe normal school curriculum throughout the studyperiod

Multicomponent Weight ManagementInterventions Improve Weight Outcomes inAdolescentsOf the 13 included studies there were 14 groups whoreceived a MWMI and 11 no-treatment controlgroups Of these effect sizes were able to be calculatedfor nine intervention groups and seven control groups(Table III) Seven intervention groups had small to me-dium positive effects indicating successful weight loss(Brennan et al 2012 Croker et al 2012 Danielsenet al 2013 DeBar et al 2012 Lochrie et al 2013Lubans et al 2012 Nguyen Shrewsbury et al2012) and two intervention groups had no effect(Neumark-Sztainer et al 2010 Nguyen Shrewsburyet al 2012) All seven control groups showed no ef-fect on weight

Of the studies for which effect size could not be cal-culated the results were similar Mellin et al (1987)Morgan et al (2012) Sacher et al (2010) andWadden et al (1990) all observed significant weightloss following intervention Morgan et al (2012) andSacher et al (2010) also showed that these changeswere significantly different to changes observed in thecontrol groups No studies observed significant weightchange in the control groups

Correlation Between Self-Esteem Improvementand Weight Loss Effect SizesThere is a strong (rfrac14 641 R2frac140410) positive linearrelationship between effect sizes for self-esteem im-provement and weight loss across all intervention andcontrol groups (pfrac14 008)T

Quantitative Data AnalysisDifferences between intervention and control groupsfor change in self-esteem are presented in Figure 2aThis analysis included seven intervention groups(nfrac14 191) and seven control groups (nfrac14 132) with

interventions or intensive treatment phases rangingfrom 9 weeks to 6 months in duration A moderatelevel of the variation across studies was owing to het-erogeneity (I2frac14464 Higgins Thompson Deeksamp Altman 2003) The overall summary effect showed

no effect on self-esteem as a result of interventionSMD of 027 (95 confidence interval 004 059)zfrac14 169 and pfrac14 092 However all studies exceptone favored the intervention for improvements in self-esteem

The difference between intervention and controlgroups for change in BMI z-score is illustrated inFigure 2b This analysis included five interventiongroups (nfrac14 135) and five control groups (nfrac14 82) withinterventions ranging from 9 weeks to 6 months induration Heterogeneity in this sample was low(I2frac14177 Higgins et al 2003) and the overall sum-mary effect was 017 (022 011) BMI z-scorepoints (zfrac14613 and plt 001) indicating statisticallysignificant weight loss following MWMI

Discussion

The purpose of this review was to examine the effectof MWMIs on self-esteem in overweight and obeseadolescents Increased self-esteem is proposed as a keyfactor for maintaining long-term weight management(Elfhag amp Rossner 2005 French et al 1995Roberts 2006) A secondary outcome of this reviewwas to examine the impact of MWMIs on weight lossand whether this was associated with improvements inself-esteem

The meta-analysis showed no difference in self-esteem between the intervention and control groupsHowever six of the seven studies in the meta-analysisfavored the intervention over control for improve-ments in self-esteem and four of the six studies notincluded in the meta-analysis found significant im-provements in self-esteem following intervention Thelatter of these findings are similar to those of an earlierreview (Lowry et al 2007) that showed improve-ments in self-esteem following weight managementinterventions in a pediatric population particularlywhen certain intervention features were presentSimilarly a number of intervention features that con-tributed to an increased likelihood of improving self-esteem were identified in this review

Improvements in self-esteem regardless of weightloss have been demonstrated in children who tookpart in weight management interventions thatincluded a focus on building self-esteem and it is rec-ommended that this be a focus of all pediatric weightmanagement interventions (Lowry et al 2007) Yetthe majority of studies identified in this review did notinclude building self-esteem as a key aspect of theirintervention Nguyen Shrewsbury et al (2012)described the greatest focus on self-esteem (one75-min group session focused on building self-esteem)and also resulted in the largest treatment effect (057)and a significant improvement in self-esteem (NguyenShrewsbury et al 2012) A focus on similar topics

such as body image social support and managing bul-lying may also contribute to improvements in self-esteem (Croker et al 2012 Pierce amp Wardle 1997Tiggemann 2005) however these findings highlightthe lack of uptake of these recommendations

Among overweight and obese youth reductions inself-esteem are often observed in domains of physicalappearance and physical ability (Franklin DenyerSteinbeck Caterson amp Hill 2006 French et al1995 Latzer amp Stein 2013 Lowry et al 2007)Particularly for adolescent girls body image is a keyconcern (Cave Fildes Luckett amp Wearring 2015)and comprises a large portion of global self-esteem(Lowry et al 2007 Pesa Syre amp Jones 2000)However weight loss and associated changes in phys-ical appearance do not necessarily reflect improve-ments in self-esteem (Lowry et al 2007) Changes inbody-esteem often occur more rapidly than changes inglobal self-esteem as a result of weight management(Lowry et al 2007) This may explain the lack ofchange observed in global self-esteem in this meta-analysis and highlights the need to also include body-esteem (or physical self-esteem) as a focus and out-come of weight management interventions foradolescents

Parental involvement in adolescent weight manage-ment interventions is a critical component for success-ful weight loss and may also be important forimproving self-esteem (Lowry et al 2007) Weight-related teasing from family is shown to be negativelyassociated with self-esteem in overweight adolescentswhereas family connectedness was positively associ-ated with adolescent self-esteem (Fulkerson StraussNeumark-Sztainer Story amp Boutelle 2007) The in-clusion of parents in weight management interventionsfosters a safer and more encouraging home environ-ment for the adolescent (Lowry et al 2007) which isassociated with increased self-esteem in nonover-weight children (Marx amp Neumark-Sztainer 2005)All studies in the present review baring one includedparents in the intervention Parental involvementshould continue to be a key component of weightmanagement interventions to ensure a supportivehome environment for the adolescent to help fosterpositive self-esteem

Weight management interventions that used agroup setting to target self-esteem have shown im-provements in self-esteem without significant weightchange (Lowry et al 2007 Sherman AlexanderGomez Kim amp Marole 1992) The ability of the peergroup setting to provide opportunities for bondingsupport feelings of belonging development of peer-based skills and positive peer exchanges is key toincreasing self-esteem (Lowry et al 2007) The im-portance of this element is being acknowledged in the

Measures of self-esteem are self-reported and there-fore subjective Responses to questionnaires are likelyto be influenced by individual (eg age gender) andenvironmental (eg cultural group socioeconomicstatus) factors (Khanlou 2004) Changes followinginterventions may represent genuine long-termchanges in self-esteem or may be due to short-termfluctuations in self-esteem in response to specificevents (eg winning a sporting event or performanceon a test at school) (Kernis 1993) While validatedtools were used to measure self-esteem in all studies itwas difficult to conclude whether outcomes were en-tirely dependent on the intervention without inclusionof a no-treatment control group

The variety of self-esteem assessment tools also addsto the difficulty of interpretation Across the 13 studies inthis review five different tools were used with differentquestions and different scales Even within tools therewere different scales used to report the results (RosenbergSelf-esteem Scale) and different versions of the same ques-tionnaire (Harterrsquos Self-perception Profile for ChildrenHarterrsquos Self-perception Profile for Adolescents) HarterrsquosSelf-Perception Profile (Harterrsquos Self-perception Profilefor Adolescents for adolescents) which measures ninesubscales of self-esteem including physical self-esteem issuggested as the most appropriate measure for adolescentself-esteem (Lowry et al 2007) It was also the mostcommonly used tool among papers included in this re-view While Cohenrsquos d effect sizes were used to stand-ardize results in this review the consistent use of one toolwould provide the ability to compare raw self-esteemscores and create a stronger analysis in the future

Results from this review support evidence thatMWMIs induce weight loss in overweight and obeseadolescents (Hoelscher Kirk Ritchie ampCunningham-Sabo 2013 Kelly amp Melnyk 2008Luttikhuis et al 2009) The change in BMI z-score inthe present meta-analysis (017 [022 011]) wassimilar to the clinically meaningful weight loss re-ported in the 2009 Cochrane Review in children 12years at 6 months follow up from a lifestyle weightmanagement intervention (014 [017 012])(Luttikhuis et al 2009) Jelalian Mehlenbeck Lloyd-Richardson Birmaher and Wing (2006) and WalkerGately Bewick and Hill (2003) have demonstratedassociations between weight loss and increased self-esteem in overweight and obese adolescents after at-tending a weight-management intervention Similarlyin the present review a strong positive relationship be-tween treatment effects for weight loss and improve-ment in self-esteem was identified However itremains unclear whether the improvement in self-esteem was as a result of successful weight loss orwhether it was a contributing factor toward successful

weight loss Nonetheless building self-esteem shouldbe a key focus of MWMIs as improved self-esteem ap-

pears to be linked to enhanced weight lossA key strength of this review was that all included

studies had strong designs and presented level II evi-dence (Coleman et al 2009) However to further elu-

cidate the role of self-esteem in adolescent weightmanagement future research should consider power-

ing studies to detect changes in psychosocial as well asphysiological outcomes Only one study in this reviewwas powered to detect a change in psychosocial out-

comes (Daley et al 2006) which may explain thelack of significant results observed for self-esteem

Additionally a large number of included studies didnot describe their method of handling withdrawals or

use blinding to prevent the introduction of bias Toimprove confidence in the effectiveness of MWMIs

and reduce the risk of bias future studies should bedesigned with concealed allocation and document andreport in detail the flow of participants

Identification of intervention components that im-

prove self-esteem is important for future weight man-agement intervention design Included interventionswere heterogeneous offering different levels of diet-

ary physical activity and behavioral interventionwhich may have collectively or individually influenced

the results Inconsistent reporting of intervention andcomparator conditions make it difficult to elucidate

the components that contributed to improvements inself-esteem Future studies should report intervention

and comparator procedures in adequate detail so thatsuccessful components can be identified and repli-cated These limitations highlight areas for improve-

ment to develop best-practice guidelines forundertaking and evaluating MWMIs in adolescents to

enhance self-esteem

Conclusion

Overweight and obese adolescents experience low

self-esteem largely owing to poor body image yetthis meta-analysis found no improvement in self-esteem even with significant weight loss Although it

was noted that interventions that had larger effects onself-esteem also had larger effects on weight loss The

incorporation of intervention components that wereidentified to contribute to improvements in self-

esteem may assist future weight management interven-tions to improve the self-esteem of overweight and

obese adolescents Furthermore a consistent measureof self-esteem would enable easier interpretation ofself-esteem scores and comparison of results across

studies to improve our understanding of the relation-ship between self-esteem and weight management in

adolescents

The Impact of Weight Management on Self-Esteem 385

self-esteem was observed following four MWMIsacross three studies (Croker et al 2012 Danielsenet al 2013 Nguyen Shrewsbury et al 2012) Fivestudies showed no effect on adolescent self-esteem fol-lowing MWMI (Brennan et al 2012 DeBar et al2012 Lochrie et al 2013 Lubans et al 2012Neumark-Sztainer et al 2010) No positive effects onself-esteem were observed in any of the controlgroups One wait-listed control group (Croker et al2012) showed a small negative effect on self-esteem

Mixed results were also observed in the studies forwhich an effect size could not be calculatedImprovements in adolescent self-esteem were observedfollowing MWMIs by Daley et al (2006) Mellin et al(1987) Sacher et al (2010) and Wadden et al(1990) However only Daley et al (2006) reportedthat this change was different to that observed in thecontrol group No changes in self-esteem were de-tected following intervention by Morgan et al (2012)although a significant decline in self-esteem wasobserved in the wait-listed control group who receivedthe normal school curriculum throughout the studyperiod

Multicomponent Weight ManagementInterventions Improve Weight Outcomes inAdolescentsOf the 13 included studies there were 14 groups whoreceived a MWMI and 11 no-treatment controlgroups Of these effect sizes were able to be calculatedfor nine intervention groups and seven control groups(Table III) Seven intervention groups had small to me-dium positive effects indicating successful weight loss(Brennan et al 2012 Croker et al 2012 Danielsenet al 2013 DeBar et al 2012 Lochrie et al 2013Lubans et al 2012 Nguyen Shrewsbury et al2012) and two intervention groups had no effect(Neumark-Sztainer et al 2010 Nguyen Shrewsburyet al 2012) All seven control groups showed no ef-fect on weight

Of the studies for which effect size could not be cal-culated the results were similar Mellin et al (1987)Morgan et al (2012) Sacher et al (2010) andWadden et al (1990) all observed significant weightloss following intervention Morgan et al (2012) andSacher et al (2010) also showed that these changeswere significantly different to changes observed in thecontrol groups No studies observed significant weightchange in the control groups

Correlation Between Self-Esteem Improvementand Weight Loss Effect SizesThere is a strong (rfrac14 641 R2frac140410) positive linearrelationship between effect sizes for self-esteem im-provement and weight loss across all intervention andcontrol groups (pfrac14 008)T

Quantitative Data AnalysisDifferences between intervention and control groupsfor change in self-esteem are presented in Figure 2aThis analysis included seven intervention groups(nfrac14 191) and seven control groups (nfrac14 132) with

interventions or intensive treatment phases rangingfrom 9 weeks to 6 months in duration A moderatelevel of the variation across studies was owing to het-erogeneity (I2frac14464 Higgins Thompson Deeksamp Altman 2003) The overall summary effect showed

no effect on self-esteem as a result of interventionSMD of 027 (95 confidence interval 004 059)zfrac14 169 and pfrac14 092 However all studies exceptone favored the intervention for improvements in self-esteem

The difference between intervention and controlgroups for change in BMI z-score is illustrated inFigure 2b This analysis included five interventiongroups (nfrac14 135) and five control groups (nfrac14 82) withinterventions ranging from 9 weeks to 6 months induration Heterogeneity in this sample was low(I2frac14177 Higgins et al 2003) and the overall sum-mary effect was 017 (022 011) BMI z-scorepoints (zfrac14613 and plt 001) indicating statisticallysignificant weight loss following MWMI

Discussion

The purpose of this review was to examine the effectof MWMIs on self-esteem in overweight and obeseadolescents Increased self-esteem is proposed as a keyfactor for maintaining long-term weight management(Elfhag amp Rossner 2005 French et al 1995Roberts 2006) A secondary outcome of this reviewwas to examine the impact of MWMIs on weight lossand whether this was associated with improvements inself-esteem

The meta-analysis showed no difference in self-esteem between the intervention and control groupsHowever six of the seven studies in the meta-analysisfavored the intervention over control for improve-ments in self-esteem and four of the six studies notincluded in the meta-analysis found significant im-provements in self-esteem following intervention Thelatter of these findings are similar to those of an earlierreview (Lowry et al 2007) that showed improve-ments in self-esteem following weight managementinterventions in a pediatric population particularlywhen certain intervention features were presentSimilarly a number of intervention features that con-tributed to an increased likelihood of improving self-esteem were identified in this review

Improvements in self-esteem regardless of weightloss have been demonstrated in children who tookpart in weight management interventions thatincluded a focus on building self-esteem and it is rec-ommended that this be a focus of all pediatric weightmanagement interventions (Lowry et al 2007) Yetthe majority of studies identified in this review did notinclude building self-esteem as a key aspect of theirintervention Nguyen Shrewsbury et al (2012)described the greatest focus on self-esteem (one75-min group session focused on building self-esteem)and also resulted in the largest treatment effect (057)and a significant improvement in self-esteem (NguyenShrewsbury et al 2012) A focus on similar topics

such as body image social support and managing bul-lying may also contribute to improvements in self-esteem (Croker et al 2012 Pierce amp Wardle 1997Tiggemann 2005) however these findings highlightthe lack of uptake of these recommendations

Among overweight and obese youth reductions inself-esteem are often observed in domains of physicalappearance and physical ability (Franklin DenyerSteinbeck Caterson amp Hill 2006 French et al1995 Latzer amp Stein 2013 Lowry et al 2007)Particularly for adolescent girls body image is a keyconcern (Cave Fildes Luckett amp Wearring 2015)and comprises a large portion of global self-esteem(Lowry et al 2007 Pesa Syre amp Jones 2000)However weight loss and associated changes in phys-ical appearance do not necessarily reflect improve-ments in self-esteem (Lowry et al 2007) Changes inbody-esteem often occur more rapidly than changes inglobal self-esteem as a result of weight management(Lowry et al 2007) This may explain the lack ofchange observed in global self-esteem in this meta-analysis and highlights the need to also include body-esteem (or physical self-esteem) as a focus and out-come of weight management interventions foradolescents

Parental involvement in adolescent weight manage-ment interventions is a critical component for success-ful weight loss and may also be important forimproving self-esteem (Lowry et al 2007) Weight-related teasing from family is shown to be negativelyassociated with self-esteem in overweight adolescentswhereas family connectedness was positively associ-ated with adolescent self-esteem (Fulkerson StraussNeumark-Sztainer Story amp Boutelle 2007) The in-clusion of parents in weight management interventionsfosters a safer and more encouraging home environ-ment for the adolescent (Lowry et al 2007) which isassociated with increased self-esteem in nonover-weight children (Marx amp Neumark-Sztainer 2005)All studies in the present review baring one includedparents in the intervention Parental involvementshould continue to be a key component of weightmanagement interventions to ensure a supportivehome environment for the adolescent to help fosterpositive self-esteem

Weight management interventions that used agroup setting to target self-esteem have shown im-provements in self-esteem without significant weightchange (Lowry et al 2007 Sherman AlexanderGomez Kim amp Marole 1992) The ability of the peergroup setting to provide opportunities for bondingsupport feelings of belonging development of peer-based skills and positive peer exchanges is key toincreasing self-esteem (Lowry et al 2007) The im-portance of this element is being acknowledged in the

field with all the studies in this review baring twousing group sessions in their intervention

Measures of self-esteem are self-reported and there-fore subjective Responses to questionnaires are likelyto be influenced by individual (eg age gender) andenvironmental (eg cultural group socioeconomicstatus) factors (Khanlou 2004) Changes followinginterventions may represent genuine long-termchanges in self-esteem or may be due to short-termfluctuations in self-esteem in response to specificevents (eg winning a sporting event or performanceon a test at school) (Kernis 1993) While validatedtools were used to measure self-esteem in all studies itwas difficult to conclude whether outcomes were en-tirely dependent on the intervention without inclusionof a no-treatment control group

The variety of self-esteem assessment tools also addsto the difficulty of interpretation Across the 13 studies inthis review five different tools were used with differentquestions and different scales Even within tools therewere different scales used to report the results (RosenbergSelf-esteem Scale) and different versions of the same ques-tionnaire (Harterrsquos Self-perception Profile for ChildrenHarterrsquos Self-perception Profile for Adolescents) HarterrsquosSelf-Perception Profile (Harterrsquos Self-perception Profilefor Adolescents for adolescents) which measures ninesubscales of self-esteem including physical self-esteem issuggested as the most appropriate measure for adolescentself-esteem (Lowry et al 2007) It was also the mostcommonly used tool among papers included in this re-view While Cohenrsquos d effect sizes were used to stand-ardize results in this review the consistent use of one toolwould provide the ability to compare raw self-esteemscores and create a stronger analysis in the future

Results from this review support evidence thatMWMIs induce weight loss in overweight and obeseadolescents (Hoelscher Kirk Ritchie ampCunningham-Sabo 2013 Kelly amp Melnyk 2008Luttikhuis et al 2009) The change in BMI z-score inthe present meta-analysis (017 [022 011]) wassimilar to the clinically meaningful weight loss re-ported in the 2009 Cochrane Review in children 12years at 6 months follow up from a lifestyle weightmanagement intervention (014 [017 012])(Luttikhuis et al 2009) Jelalian Mehlenbeck Lloyd-Richardson Birmaher and Wing (2006) and WalkerGately Bewick and Hill (2003) have demonstratedassociations between weight loss and increased self-esteem in overweight and obese adolescents after at-tending a weight-management intervention Similarlyin the present review a strong positive relationship be-tween treatment effects for weight loss and improve-ment in self-esteem was identified However itremains unclear whether the improvement in self-esteem was as a result of successful weight loss orwhether it was a contributing factor toward successful

weight loss Nonetheless building self-esteem shouldbe a key focus of MWMIs as improved self-esteem ap-

pears to be linked to enhanced weight lossA key strength of this review was that all included

studies had strong designs and presented level II evi-dence (Coleman et al 2009) However to further elu-

cidate the role of self-esteem in adolescent weightmanagement future research should consider power-

ing studies to detect changes in psychosocial as well asphysiological outcomes Only one study in this reviewwas powered to detect a change in psychosocial out-

comes (Daley et al 2006) which may explain thelack of significant results observed for self-esteem

Additionally a large number of included studies didnot describe their method of handling withdrawals or

use blinding to prevent the introduction of bias Toimprove confidence in the effectiveness of MWMIs

and reduce the risk of bias future studies should bedesigned with concealed allocation and document andreport in detail the flow of participants

Identification of intervention components that im-

prove self-esteem is important for future weight man-agement intervention design Included interventionswere heterogeneous offering different levels of diet-

ary physical activity and behavioral interventionwhich may have collectively or individually influenced

the results Inconsistent reporting of intervention andcomparator conditions make it difficult to elucidate

the components that contributed to improvements inself-esteem Future studies should report intervention

and comparator procedures in adequate detail so thatsuccessful components can be identified and repli-cated These limitations highlight areas for improve-

ment to develop best-practice guidelines forundertaking and evaluating MWMIs in adolescents to

enhance self-esteem

Conclusion

Overweight and obese adolescents experience low

self-esteem largely owing to poor body image yetthis meta-analysis found no improvement in self-esteem even with significant weight loss Although it

was noted that interventions that had larger effects onself-esteem also had larger effects on weight loss The

incorporation of intervention components that wereidentified to contribute to improvements in self-

esteem may assist future weight management interven-tions to improve the self-esteem of overweight and

obese adolescents Furthermore a consistent measureof self-esteem would enable easier interpretation ofself-esteem scores and comparison of results across

studies to improve our understanding of the relation-ship between self-esteem and weight management in

adolescents

self-esteem was observed following four MWMIsacross three studies (Croker et al 2012 Danielsenet al 2013 Nguyen Shrewsbury et al 2012) Fivestudies showed no effect on adolescent self-esteem fol-lowing MWMI (Brennan et al 2012 DeBar et al2012 Lochrie et al 2013 Lubans et al 2012Neumark-Sztainer et al 2010) No positive effects onself-esteem were observed in any of the controlgroups One wait-listed control group (Croker et al2012) showed a small negative effect on self-esteem

Mixed results were also observed in the studies forwhich an effect size could not be calculatedImprovements in adolescent self-esteem were observedfollowing MWMIs by Daley et al (2006) Mellin et al(1987) Sacher et al (2010) and Wadden et al(1990) However only Daley et al (2006) reportedthat this change was different to that observed in thecontrol group No changes in self-esteem were de-tected following intervention by Morgan et al (2012)although a significant decline in self-esteem wasobserved in the wait-listed control group who receivedthe normal school curriculum throughout the studyperiod

Multicomponent Weight ManagementInterventions Improve Weight Outcomes inAdolescentsOf the 13 included studies there were 14 groups whoreceived a MWMI and 11 no-treatment controlgroups Of these effect sizes were able to be calculatedfor nine intervention groups and seven control groups(Table III) Seven intervention groups had small to me-dium positive effects indicating successful weight loss(Brennan et al 2012 Croker et al 2012 Danielsenet al 2013 DeBar et al 2012 Lochrie et al 2013Lubans et al 2012 Nguyen Shrewsbury et al2012) and two intervention groups had no effect(Neumark-Sztainer et al 2010 Nguyen Shrewsburyet al 2012) All seven control groups showed no ef-fect on weight

Of the studies for which effect size could not be cal-culated the results were similar Mellin et al (1987)Morgan et al (2012) Sacher et al (2010) andWadden et al (1990) all observed significant weightloss following intervention Morgan et al (2012) andSacher et al (2010) also showed that these changeswere significantly different to changes observed in thecontrol groups No studies observed significant weightchange in the control groups

Correlation Between Self-Esteem Improvementand Weight Loss Effect SizesThere is a strong (rfrac14 641 R2frac140410) positive linearrelationship between effect sizes for self-esteem im-provement and weight loss across all intervention andcontrol groups (pfrac14 008)T

Quantitative Data AnalysisDifferences between intervention and control groupsfor change in self-esteem are presented in Figure 2aThis analysis included seven intervention groups(nfrac14 191) and seven control groups (nfrac14 132) with

interventions or intensive treatment phases rangingfrom 9 weeks to 6 months in duration A moderatelevel of the variation across studies was owing to het-erogeneity (I2frac14464 Higgins Thompson Deeksamp Altman 2003) The overall summary effect showed

no effect on self-esteem as a result of interventionSMD of 027 (95 confidence interval 004 059)zfrac14 169 and pfrac14 092 However all studies exceptone favored the intervention for improvements in self-esteem

The difference between intervention and controlgroups for change in BMI z-score is illustrated inFigure 2b This analysis included five interventiongroups (nfrac14 135) and five control groups (nfrac14 82) withinterventions ranging from 9 weeks to 6 months induration Heterogeneity in this sample was low(I2frac14177 Higgins et al 2003) and the overall sum-mary effect was 017 (022 011) BMI z-scorepoints (zfrac14613 and plt 001) indicating statisticallysignificant weight loss following MWMI

Discussion

The purpose of this review was to examine the effectof MWMIs on self-esteem in overweight and obeseadolescents Increased self-esteem is proposed as a keyfactor for maintaining long-term weight management(Elfhag amp Rossner 2005 French et al 1995Roberts 2006) A secondary outcome of this reviewwas to examine the impact of MWMIs on weight lossand whether this was associated with improvements inself-esteem

The meta-analysis showed no difference in self-esteem between the intervention and control groupsHowever six of the seven studies in the meta-analysisfavored the intervention over control for improve-ments in self-esteem and four of the six studies notincluded in the meta-analysis found significant im-provements in self-esteem following intervention Thelatter of these findings are similar to those of an earlierreview (Lowry et al 2007) that showed improve-ments in self-esteem following weight managementinterventions in a pediatric population particularlywhen certain intervention features were presentSimilarly a number of intervention features that con-tributed to an increased likelihood of improving self-esteem were identified in this review

Improvements in self-esteem regardless of weightloss have been demonstrated in children who tookpart in weight management interventions thatincluded a focus on building self-esteem and it is rec-ommended that this be a focus of all pediatric weightmanagement interventions (Lowry et al 2007) Yetthe majority of studies identified in this review did notinclude building self-esteem as a key aspect of theirintervention Nguyen Shrewsbury et al (2012)described the greatest focus on self-esteem (one75-min group session focused on building self-esteem)and also resulted in the largest treatment effect (057)and a significant improvement in self-esteem (NguyenShrewsbury et al 2012) A focus on similar topics

such as body image social support and managing bul-lying may also contribute to improvements in self-esteem (Croker et al 2012 Pierce amp Wardle 1997Tiggemann 2005) however these findings highlightthe lack of uptake of these recommendations

Among overweight and obese youth reductions inself-esteem are often observed in domains of physicalappearance and physical ability (Franklin DenyerSteinbeck Caterson amp Hill 2006 French et al1995 Latzer amp Stein 2013 Lowry et al 2007)Particularly for adolescent girls body image is a keyconcern (Cave Fildes Luckett amp Wearring 2015)and comprises a large portion of global self-esteem(Lowry et al 2007 Pesa Syre amp Jones 2000)However weight loss and associated changes in phys-ical appearance do not necessarily reflect improve-ments in self-esteem (Lowry et al 2007) Changes inbody-esteem often occur more rapidly than changes inglobal self-esteem as a result of weight management(Lowry et al 2007) This may explain the lack ofchange observed in global self-esteem in this meta-analysis and highlights the need to also include body-esteem (or physical self-esteem) as a focus and out-come of weight management interventions foradolescents

Parental involvement in adolescent weight manage-ment interventions is a critical component for success-ful weight loss and may also be important forimproving self-esteem (Lowry et al 2007) Weight-related teasing from family is shown to be negativelyassociated with self-esteem in overweight adolescentswhereas family connectedness was positively associ-ated with adolescent self-esteem (Fulkerson StraussNeumark-Sztainer Story amp Boutelle 2007) The in-clusion of parents in weight management interventionsfosters a safer and more encouraging home environ-ment for the adolescent (Lowry et al 2007) which isassociated with increased self-esteem in nonover-weight children (Marx amp Neumark-Sztainer 2005)All studies in the present review baring one includedparents in the intervention Parental involvementshould continue to be a key component of weightmanagement interventions to ensure a supportivehome environment for the adolescent to help fosterpositive self-esteem

Weight management interventions that used agroup setting to target self-esteem have shown im-provements in self-esteem without significant weightchange (Lowry et al 2007 Sherman AlexanderGomez Kim amp Marole 1992) The ability of the peergroup setting to provide opportunities for bondingsupport feelings of belonging development of peer-based skills and positive peer exchanges is key toincreasing self-esteem (Lowry et al 2007) The im-portance of this element is being acknowledged in the

field with all the studies in this review baring twousing group sessions in their intervention

Measures of self-esteem are self-reported and there-fore subjective Responses to questionnaires are likelyto be influenced by individual (eg age gender) andenvironmental (eg cultural group socioeconomicstatus) factors (Khanlou 2004) Changes followinginterventions may represent genuine long-termchanges in self-esteem or may be due to short-termfluctuations in self-esteem in response to specificevents (eg winning a sporting event or performanceon a test at school) (Kernis 1993) While validatedtools were used to measure self-esteem in all studies itwas difficult to conclude whether outcomes were en-tirely dependent on the intervention without inclusionof a no-treatment control group

The variety of self-esteem assessment tools also addsto the difficulty of interpretation Across the 13 studies inthis review five different tools were used with differentquestions and different scales Even within tools therewere different scales used to report the results (RosenbergSelf-esteem Scale) and different versions of the same ques-tionnaire (Harterrsquos Self-perception Profile for ChildrenHarterrsquos Self-perception Profile for Adolescents) HarterrsquosSelf-Perception Profile (Harterrsquos Self-perception Profilefor Adolescents for adolescents) which measures ninesubscales of self-esteem including physical self-esteem issuggested as the most appropriate measure for adolescentself-esteem (Lowry et al 2007) It was also the mostcommonly used tool among papers included in this re-view While Cohenrsquos d effect sizes were used to stand-ardize results in this review the consistent use of one toolwould provide the ability to compare raw self-esteemscores and create a stronger analysis in the future

Results from this review support evidence thatMWMIs induce weight loss in overweight and obeseadolescents (Hoelscher Kirk Ritchie ampCunningham-Sabo 2013 Kelly amp Melnyk 2008Luttikhuis et al 2009) The change in BMI z-score inthe present meta-analysis (017 [022 011]) wassimilar to the clinically meaningful weight loss re-ported in the 2009 Cochrane Review in children 12years at 6 months follow up from a lifestyle weightmanagement intervention (014 [017 012])(Luttikhuis et al 2009) Jelalian Mehlenbeck Lloyd-Richardson Birmaher and Wing (2006) and WalkerGately Bewick and Hill (2003) have demonstratedassociations between weight loss and increased self-esteem in overweight and obese adolescents after at-tending a weight-management intervention Similarlyin the present review a strong positive relationship be-tween treatment effects for weight loss and improve-ment in self-esteem was identified However itremains unclear whether the improvement in self-esteem was as a result of successful weight loss orwhether it was a contributing factor toward successful

weight loss Nonetheless building self-esteem shouldbe a key focus of MWMIs as improved self-esteem ap-

pears to be linked to enhanced weight lossA key strength of this review was that all included

studies had strong designs and presented level II evi-dence (Coleman et al 2009) However to further elu-

cidate the role of self-esteem in adolescent weightmanagement future research should consider power-

ing studies to detect changes in psychosocial as well asphysiological outcomes Only one study in this reviewwas powered to detect a change in psychosocial out-

comes (Daley et al 2006) which may explain thelack of significant results observed for self-esteem

Additionally a large number of included studies didnot describe their method of handling withdrawals or

use blinding to prevent the introduction of bias Toimprove confidence in the effectiveness of MWMIs

and reduce the risk of bias future studies should bedesigned with concealed allocation and document andreport in detail the flow of participants

Identification of intervention components that im-

prove self-esteem is important for future weight man-agement intervention design Included interventionswere heterogeneous offering different levels of diet-

ary physical activity and behavioral interventionwhich may have collectively or individually influenced

the results Inconsistent reporting of intervention andcomparator conditions make it difficult to elucidate

the components that contributed to improvements inself-esteem Future studies should report intervention

and comparator procedures in adequate detail so thatsuccessful components can be identified and repli-cated These limitations highlight areas for improve-

ment to develop best-practice guidelines forundertaking and evaluating MWMIs in adolescents to

enhance self-esteem

Conclusion

Overweight and obese adolescents experience low

self-esteem largely owing to poor body image yetthis meta-analysis found no improvement in self-esteem even with significant weight loss Although it

was noted that interventions that had larger effects onself-esteem also had larger effects on weight loss The

incorporation of intervention components that wereidentified to contribute to improvements in self-

esteem may assist future weight management interven-tions to improve the self-esteem of overweight and

obese adolescents Furthermore a consistent measureof self-esteem would enable easier interpretation ofself-esteem scores and comparison of results across

studies to improve our understanding of the relation-ship between self-esteem and weight management in

adolescents

self-esteem was observed following four MWMIsacross three studies (Croker et al 2012 Danielsenet al 2013 Nguyen Shrewsbury et al 2012) Fivestudies showed no effect on adolescent self-esteem fol-lowing MWMI (Brennan et al 2012 DeBar et al2012 Lochrie et al 2013 Lubans et al 2012Neumark-Sztainer et al 2010) No positive effects onself-esteem were observed in any of the controlgroups One wait-listed control group (Croker et al2012) showed a small negative effect on self-esteem

Mixed results were also observed in the studies forwhich an effect size could not be calculatedImprovements in adolescent self-esteem were observedfollowing MWMIs by Daley et al (2006) Mellin et al(1987) Sacher et al (2010) and Wadden et al(1990) However only Daley et al (2006) reportedthat this change was different to that observed in thecontrol group No changes in self-esteem were de-tected following intervention by Morgan et al (2012)although a significant decline in self-esteem wasobserved in the wait-listed control group who receivedthe normal school curriculum throughout the studyperiod

Multicomponent Weight ManagementInterventions Improve Weight Outcomes inAdolescentsOf the 13 included studies there were 14 groups whoreceived a MWMI and 11 no-treatment controlgroups Of these effect sizes were able to be calculatedfor nine intervention groups and seven control groups(Table III) Seven intervention groups had small to me-dium positive effects indicating successful weight loss(Brennan et al 2012 Croker et al 2012 Danielsenet al 2013 DeBar et al 2012 Lochrie et al 2013Lubans et al 2012 Nguyen Shrewsbury et al2012) and two intervention groups had no effect(Neumark-Sztainer et al 2010 Nguyen Shrewsburyet al 2012) All seven control groups showed no ef-fect on weight

Of the studies for which effect size could not be cal-culated the results were similar Mellin et al (1987)Morgan et al (2012) Sacher et al (2010) andWadden et al (1990) all observed significant weightloss following intervention Morgan et al (2012) andSacher et al (2010) also showed that these changeswere significantly different to changes observed in thecontrol groups No studies observed significant weightchange in the control groups

Correlation Between Self-Esteem Improvementand Weight Loss Effect SizesThere is a strong (rfrac14 641 R2frac140410) positive linearrelationship between effect sizes for self-esteem im-provement and weight loss across all intervention andcontrol groups (pfrac14 008)T

Quantitative Data AnalysisDifferences between intervention and control groupsfor change in self-esteem are presented in Figure 2aThis analysis included seven intervention groups(nfrac14 191) and seven control groups (nfrac14 132) with

interventions or intensive treatment phases rangingfrom 9 weeks to 6 months in duration A moderatelevel of the variation across studies was owing to het-erogeneity (I2frac14464 Higgins Thompson Deeksamp Altman 2003) The overall summary effect showed

no effect on self-esteem as a result of interventionSMD of 027 (95 confidence interval 004 059)zfrac14 169 and pfrac14 092 However all studies exceptone favored the intervention for improvements in self-esteem

The difference between intervention and controlgroups for change in BMI z-score is illustrated inFigure 2b This analysis included five interventiongroups (nfrac14 135) and five control groups (nfrac14 82) withinterventions ranging from 9 weeks to 6 months induration Heterogeneity in this sample was low(I2frac14177 Higgins et al 2003) and the overall sum-mary effect was 017 (022 011) BMI z-scorepoints (zfrac14613 and plt 001) indicating statisticallysignificant weight loss following MWMI

Discussion

The purpose of this review was to examine the effectof MWMIs on self-esteem in overweight and obeseadolescents Increased self-esteem is proposed as a keyfactor for maintaining long-term weight management(Elfhag amp Rossner 2005 French et al 1995Roberts 2006) A secondary outcome of this reviewwas to examine the impact of MWMIs on weight lossand whether this was associated with improvements inself-esteem

The meta-analysis showed no difference in self-esteem between the intervention and control groupsHowever six of the seven studies in the meta-analysisfavored the intervention over control for improve-ments in self-esteem and four of the six studies notincluded in the meta-analysis found significant im-provements in self-esteem following intervention Thelatter of these findings are similar to those of an earlierreview (Lowry et al 2007) that showed improve-ments in self-esteem following weight managementinterventions in a pediatric population particularlywhen certain intervention features were presentSimilarly a number of intervention features that con-tributed to an increased likelihood of improving self-esteem were identified in this review

Improvements in self-esteem regardless of weightloss have been demonstrated in children who tookpart in weight management interventions thatincluded a focus on building self-esteem and it is rec-ommended that this be a focus of all pediatric weightmanagement interventions (Lowry et al 2007) Yetthe majority of studies identified in this review did notinclude building self-esteem as a key aspect of theirintervention Nguyen Shrewsbury et al (2012)described the greatest focus on self-esteem (one75-min group session focused on building self-esteem)and also resulted in the largest treatment effect (057)and a significant improvement in self-esteem (NguyenShrewsbury et al 2012) A focus on similar topics

such as body image social support and managing bul-lying may also contribute to improvements in self-esteem (Croker et al 2012 Pierce amp Wardle 1997Tiggemann 2005) however these findings highlightthe lack of uptake of these recommendations

Among overweight and obese youth reductions inself-esteem are often observed in domains of physicalappearance and physical ability (Franklin DenyerSteinbeck Caterson amp Hill 2006 French et al1995 Latzer amp Stein 2013 Lowry et al 2007)Particularly for adolescent girls body image is a keyconcern (Cave Fildes Luckett amp Wearring 2015)and comprises a large portion of global self-esteem(Lowry et al 2007 Pesa Syre amp Jones 2000)However weight loss and associated changes in phys-ical appearance do not necessarily reflect improve-ments in self-esteem (Lowry et al 2007) Changes inbody-esteem often occur more rapidly than changes inglobal self-esteem as a result of weight management(Lowry et al 2007) This may explain the lack ofchange observed in global self-esteem in this meta-analysis and highlights the need to also include body-esteem (or physical self-esteem) as a focus and out-come of weight management interventions foradolescents

Parental involvement in adolescent weight manage-ment interventions is a critical component for success-ful weight loss and may also be important forimproving self-esteem (Lowry et al 2007) Weight-related teasing from family is shown to be negativelyassociated with self-esteem in overweight adolescentswhereas family connectedness was positively associ-ated with adolescent self-esteem (Fulkerson StraussNeumark-Sztainer Story amp Boutelle 2007) The in-clusion of parents in weight management interventionsfosters a safer and more encouraging home environ-ment for the adolescent (Lowry et al 2007) which isassociated with increased self-esteem in nonover-weight children (Marx amp Neumark-Sztainer 2005)All studies in the present review baring one includedparents in the intervention Parental involvementshould continue to be a key component of weightmanagement interventions to ensure a supportivehome environment for the adolescent to help fosterpositive self-esteem

Weight management interventions that used agroup setting to target self-esteem have shown im-provements in self-esteem without significant weightchange (Lowry et al 2007 Sherman AlexanderGomez Kim amp Marole 1992) The ability of the peergroup setting to provide opportunities for bondingsupport feelings of belonging development of peer-based skills and positive peer exchanges is key toincreasing self-esteem (Lowry et al 2007) The im-portance of this element is being acknowledged in the

field with all the studies in this review baring twousing group sessions in their intervention

Measures of self-esteem are self-reported and there-fore subjective Responses to questionnaires are likelyto be influenced by individual (eg age gender) andenvironmental (eg cultural group socioeconomicstatus) factors (Khanlou 2004) Changes followinginterventions may represent genuine long-termchanges in self-esteem or may be due to short-termfluctuations in self-esteem in response to specificevents (eg winning a sporting event or performanceon a test at school) (Kernis 1993) While validatedtools were used to measure self-esteem in all studies itwas difficult to conclude whether outcomes were en-tirely dependent on the intervention without inclusionof a no-treatment control group

The variety of self-esteem assessment tools also addsto the difficulty of interpretation Across the 13 studies inthis review five different tools were used with differentquestions and different scales Even within tools therewere different scales used to report the results (RosenbergSelf-esteem Scale) and different versions of the same ques-tionnaire (Harterrsquos Self-perception Profile for ChildrenHarterrsquos Self-perception Profile for Adolescents) HarterrsquosSelf-Perception Profile (Harterrsquos Self-perception Profilefor Adolescents for adolescents) which measures ninesubscales of self-esteem including physical self-esteem issuggested as the most appropriate measure for adolescentself-esteem (Lowry et al 2007) It was also the mostcommonly used tool among papers included in this re-view While Cohenrsquos d effect sizes were used to stand-ardize results in this review the consistent use of one toolwould provide the ability to compare raw self-esteemscores and create a stronger analysis in the future

Results from this review support evidence thatMWMIs induce weight loss in overweight and obeseadolescents (Hoelscher Kirk Ritchie ampCunningham-Sabo 2013 Kelly amp Melnyk 2008Luttikhuis et al 2009) The change in BMI z-score inthe present meta-analysis (017 [022 011]) wassimilar to the clinically meaningful weight loss re-ported in the 2009 Cochrane Review in children 12years at 6 months follow up from a lifestyle weightmanagement intervention (014 [017 012])(Luttikhuis et al 2009) Jelalian Mehlenbeck Lloyd-Richardson Birmaher and Wing (2006) and WalkerGately Bewick and Hill (2003) have demonstratedassociations between weight loss and increased self-esteem in overweight and obese adolescents after at-tending a weight-management intervention Similarlyin the present review a strong positive relationship be-tween treatment effects for weight loss and improve-ment in self-esteem was identified However itremains unclear whether the improvement in self-esteem was as a result of successful weight loss orwhether it was a contributing factor toward successful

weight loss Nonetheless building self-esteem shouldbe a key focus of MWMIs as improved self-esteem ap-

pears to be linked to enhanced weight lossA key strength of this review was that all included

studies had strong designs and presented level II evi-dence (Coleman et al 2009) However to further elu-

cidate the role of self-esteem in adolescent weightmanagement future research should consider power-

ing studies to detect changes in psychosocial as well asphysiological outcomes Only one study in this reviewwas powered to detect a change in psychosocial out-

comes (Daley et al 2006) which may explain thelack of significant results observed for self-esteem

Additionally a large number of included studies didnot describe their method of handling withdrawals or

use blinding to prevent the introduction of bias Toimprove confidence in the effectiveness of MWMIs

and reduce the risk of bias future studies should bedesigned with concealed allocation and document andreport in detail the flow of participants

Identification of intervention components that im-

prove self-esteem is important for future weight man-agement intervention design Included interventionswere heterogeneous offering different levels of diet-

ary physical activity and behavioral interventionwhich may have collectively or individually influenced

the results Inconsistent reporting of intervention andcomparator conditions make it difficult to elucidate

the components that contributed to improvements inself-esteem Future studies should report intervention

and comparator procedures in adequate detail so thatsuccessful components can be identified and repli-cated These limitations highlight areas for improve-

ment to develop best-practice guidelines forundertaking and evaluating MWMIs in adolescents to

enhance self-esteem

Conclusion

Overweight and obese adolescents experience low

self-esteem largely owing to poor body image yetthis meta-analysis found no improvement in self-esteem even with significant weight loss Although it

was noted that interventions that had larger effects onself-esteem also had larger effects on weight loss The

incorporation of intervention components that wereidentified to contribute to improvements in self-

esteem may assist future weight management interven-tions to improve the self-esteem of overweight and

obese adolescents Furthermore a consistent measureof self-esteem would enable easier interpretation ofself-esteem scores and comparison of results across

studies to improve our understanding of the relation-ship between self-esteem and weight management in

adolescents

self-esteem was observed following four MWMIsacross three studies (Croker et al 2012 Danielsenet al 2013 Nguyen Shrewsbury et al 2012) Fivestudies showed no effect on adolescent self-esteem fol-lowing MWMI (Brennan et al 2012 DeBar et al2012 Lochrie et al 2013 Lubans et al 2012Neumark-Sztainer et al 2010) No positive effects onself-esteem were observed in any of the controlgroups One wait-listed control group (Croker et al2012) showed a small negative effect on self-esteem

Mixed results were also observed in the studies forwhich an effect size could not be calculatedImprovements in adolescent self-esteem were observedfollowing MWMIs by Daley et al (2006) Mellin et al(1987) Sacher et al (2010) and Wadden et al(1990) However only Daley et al (2006) reportedthat this change was different to that observed in thecontrol group No changes in self-esteem were de-tected following intervention by Morgan et al (2012)although a significant decline in self-esteem wasobserved in the wait-listed control group who receivedthe normal school curriculum throughout the studyperiod

Multicomponent Weight ManagementInterventions Improve Weight Outcomes inAdolescentsOf the 13 included studies there were 14 groups whoreceived a MWMI and 11 no-treatment controlgroups Of these effect sizes were able to be calculatedfor nine intervention groups and seven control groups(Table III) Seven intervention groups had small to me-dium positive effects indicating successful weight loss(Brennan et al 2012 Croker et al 2012 Danielsenet al 2013 DeBar et al 2012 Lochrie et al 2013Lubans et al 2012 Nguyen Shrewsbury et al2012) and two intervention groups had no effect(Neumark-Sztainer et al 2010 Nguyen Shrewsburyet al 2012) All seven control groups showed no ef-fect on weight

Of the studies for which effect size could not be cal-culated the results were similar Mellin et al (1987)Morgan et al (2012) Sacher et al (2010) andWadden et al (1990) all observed significant weightloss following intervention Morgan et al (2012) andSacher et al (2010) also showed that these changeswere significantly different to changes observed in thecontrol groups No studies observed significant weightchange in the control groups

Correlation Between Self-Esteem Improvementand Weight Loss Effect SizesThere is a strong (rfrac14 641 R2frac140410) positive linearrelationship between effect sizes for self-esteem im-provement and weight loss across all intervention andcontrol groups (pfrac14 008)T

The difference between intervention and controlgroups for change in BMI z-score is illustrated inFigure 2b This analysis included five interventiongroups (nfrac14 135) and five control groups (nfrac14 82) withinterventions ranging from 9 weeks to 6 months induration Heterogeneity in this sample was low(I2frac14177 Higgins et al 2003) and the overall sum-mary effect was 017 (022 011) BMI z-scorepoints (zfrac14613 and plt 001) indicating statisticallysignificant weight loss following MWMI

Discussion

The purpose of this review was to examine the effectof MWMIs on self-esteem in overweight and obeseadolescents Increased self-esteem is proposed as a keyfactor for maintaining long-term weight management(Elfhag amp Rossner 2005 French et al 1995Roberts 2006) A secondary outcome of this reviewwas to examine the impact of MWMIs on weight lossand whether this was associated with improvements inself-esteem

The meta-analysis showed no difference in self-esteem between the intervention and control groupsHowever six of the seven studies in the meta-analysisfavored the intervention over control for improve-ments in self-esteem and four of the six studies notincluded in the meta-analysis found significant im-provements in self-esteem following intervention Thelatter of these findings are similar to those of an earlierreview (Lowry et al 2007) that showed improve-ments in self-esteem following weight managementinterventions in a pediatric population particularlywhen certain intervention features were presentSimilarly a number of intervention features that con-tributed to an increased likelihood of improving self-esteem were identified in this review

Improvements in self-esteem regardless of weightloss have been demonstrated in children who tookpart in weight management interventions thatincluded a focus on building self-esteem and it is rec-ommended that this be a focus of all pediatric weightmanagement interventions (Lowry et al 2007) Yetthe majority of studies identified in this review did notinclude building self-esteem as a key aspect of theirintervention Nguyen Shrewsbury et al (2012)described the greatest focus on self-esteem (one75-min group session focused on building self-esteem)and also resulted in the largest treatment effect (057)and a significant improvement in self-esteem (NguyenShrewsbury et al 2012) A focus on similar topics

such as body image social support and managing bul-lying may also contribute to improvements in self-esteem (Croker et al 2012 Pierce amp Wardle 1997Tiggemann 2005) however these findings highlightthe lack of uptake of these recommendations

Among overweight and obese youth reductions inself-esteem are often observed in domains of physicalappearance and physical ability (Franklin DenyerSteinbeck Caterson amp Hill 2006 French et al1995 Latzer amp Stein 2013 Lowry et al 2007)Particularly for adolescent girls body image is a keyconcern (Cave Fildes Luckett amp Wearring 2015)and comprises a large portion of global self-esteem(Lowry et al 2007 Pesa Syre amp Jones 2000)However weight loss and associated changes in phys-ical appearance do not necessarily reflect improve-ments in self-esteem (Lowry et al 2007) Changes inbody-esteem often occur more rapidly than changes inglobal self-esteem as a result of weight management(Lowry et al 2007) This may explain the lack ofchange observed in global self-esteem in this meta-analysis and highlights the need to also include body-esteem (or physical self-esteem) as a focus and out-come of weight management interventions foradolescents

Parental involvement in adolescent weight manage-ment interventions is a critical component for success-ful weight loss and may also be important forimproving self-esteem (Lowry et al 2007) Weight-related teasing from family is shown to be negativelyassociated with self-esteem in overweight adolescentswhereas family connectedness was positively associ-ated with adolescent self-esteem (Fulkerson StraussNeumark-Sztainer Story amp Boutelle 2007) The in-clusion of parents in weight management interventionsfosters a safer and more encouraging home environ-ment for the adolescent (Lowry et al 2007) which isassociated with increased self-esteem in nonover-weight children (Marx amp Neumark-Sztainer 2005)All studies in the present review baring one includedparents in the intervention Parental involvementshould continue to be a key component of weightmanagement interventions to ensure a supportivehome environment for the adolescent to help fosterpositive self-esteem

Weight management interventions that used agroup setting to target self-esteem have shown im-provements in self-esteem without significant weightchange (Lowry et al 2007 Sherman AlexanderGomez Kim amp Marole 1992) The ability of the peergroup setting to provide opportunities for bondingsupport feelings of belonging development of peer-based skills and positive peer exchanges is key toincreasing self-esteem (Lowry et al 2007) The im-portance of this element is being acknowledged in the

field with all the studies in this review baring twousing group sessions in their intervention

Measures of self-esteem are self-reported and there-fore subjective Responses to questionnaires are likelyto be influenced by individual (eg age gender) andenvironmental (eg cultural group socioeconomicstatus) factors (Khanlou 2004) Changes followinginterventions may represent genuine long-termchanges in self-esteem or may be due to short-termfluctuations in self-esteem in response to specificevents (eg winning a sporting event or performanceon a test at school) (Kernis 1993) While validatedtools were used to measure self-esteem in all studies itwas difficult to conclude whether outcomes were en-tirely dependent on the intervention without inclusionof a no-treatment control group

The variety of self-esteem assessment tools also addsto the difficulty of interpretation Across the 13 studies inthis review five different tools were used with differentquestions and different scales Even within tools therewere different scales used to report the results (RosenbergSelf-esteem Scale) and different versions of the same ques-tionnaire (Harterrsquos Self-perception Profile for ChildrenHarterrsquos Self-perception Profile for Adolescents) HarterrsquosSelf-Perception Profile (Harterrsquos Self-perception Profilefor Adolescents for adolescents) which measures ninesubscales of self-esteem including physical self-esteem issuggested as the most appropriate measure for adolescentself-esteem (Lowry et al 2007) It was also the mostcommonly used tool among papers included in this re-view While Cohenrsquos d effect sizes were used to stand-ardize results in this review the consistent use of one toolwould provide the ability to compare raw self-esteemscores and create a stronger analysis in the future

Results from this review support evidence thatMWMIs induce weight loss in overweight and obeseadolescents (Hoelscher Kirk Ritchie ampCunningham-Sabo 2013 Kelly amp Melnyk 2008Luttikhuis et al 2009) The change in BMI z-score inthe present meta-analysis (017 [022 011]) wassimilar to the clinically meaningful weight loss re-ported in the 2009 Cochrane Review in children 12years at 6 months follow up from a lifestyle weightmanagement intervention (014 [017 012])(Luttikhuis et al 2009) Jelalian Mehlenbeck Lloyd-Richardson Birmaher and Wing (2006) and WalkerGately Bewick and Hill (2003) have demonstratedassociations between weight loss and increased self-esteem in overweight and obese adolescents after at-tending a weight-management intervention Similarlyin the present review a strong positive relationship be-tween treatment effects for weight loss and improve-ment in self-esteem was identified However itremains unclear whether the improvement in self-esteem was as a result of successful weight loss orwhether it was a contributing factor toward successful

weight loss Nonetheless building self-esteem shouldbe a key focus of MWMIs as improved self-esteem ap-

pears to be linked to enhanced weight lossA key strength of this review was that all included

studies had strong designs and presented level II evi-dence (Coleman et al 2009) However to further elu-

cidate the role of self-esteem in adolescent weightmanagement future research should consider power-

ing studies to detect changes in psychosocial as well asphysiological outcomes Only one study in this reviewwas powered to detect a change in psychosocial out-

comes (Daley et al 2006) which may explain thelack of significant results observed for self-esteem

Additionally a large number of included studies didnot describe their method of handling withdrawals or

use blinding to prevent the introduction of bias Toimprove confidence in the effectiveness of MWMIs

and reduce the risk of bias future studies should bedesigned with concealed allocation and document andreport in detail the flow of participants

Identification of intervention components that im-

prove self-esteem is important for future weight man-agement intervention design Included interventionswere heterogeneous offering different levels of diet-

ary physical activity and behavioral interventionwhich may have collectively or individually influenced

the results Inconsistent reporting of intervention andcomparator conditions make it difficult to elucidate

the components that contributed to improvements inself-esteem Future studies should report intervention

and comparator procedures in adequate detail so thatsuccessful components can be identified and repli-cated These limitations highlight areas for improve-

ment to develop best-practice guidelines forundertaking and evaluating MWMIs in adolescents to

enhance self-esteem

Conclusion

Overweight and obese adolescents experience low

self-esteem largely owing to poor body image yetthis meta-analysis found no improvement in self-esteem even with significant weight loss Although it

was noted that interventions that had larger effects onself-esteem also had larger effects on weight loss The

incorporation of intervention components that wereidentified to contribute to improvements in self-

esteem may assist future weight management interven-tions to improve the self-esteem of overweight and

obese adolescents Furthermore a consistent measureof self-esteem would enable easier interpretation ofself-esteem scores and comparison of results across

studies to improve our understanding of the relation-ship between self-esteem and weight management in

adolescents

Page 8: Systematic Review and Meta-Analysis: The Impact of ...people.uncw.edu/hakanr/documents/weightlossandselfesteem.pdf · (French, Story, & Perry, 1995; Strauss, 2000). During adolescence,

self-esteem was observed following four MWMIsacross three studies (Croker et al 2012 Danielsenet al 2013 Nguyen Shrewsbury et al 2012) Fivestudies showed no effect on adolescent self-esteem fol-lowing MWMI (Brennan et al 2012 DeBar et al2012 Lochrie et al 2013 Lubans et al 2012Neumark-Sztainer et al 2010) No positive effects onself-esteem were observed in any of the controlgroups One wait-listed control group (Croker et al2012) showed a small negative effect on self-esteem

Mixed results were also observed in the studies forwhich an effect size could not be calculatedImprovements in adolescent self-esteem were observedfollowing MWMIs by Daley et al (2006) Mellin et al(1987) Sacher et al (2010) and Wadden et al(1990) However only Daley et al (2006) reportedthat this change was different to that observed in thecontrol group No changes in self-esteem were de-tected following intervention by Morgan et al (2012)although a significant decline in self-esteem wasobserved in the wait-listed control group who receivedthe normal school curriculum throughout the studyperiod

Multicomponent Weight ManagementInterventions Improve Weight Outcomes inAdolescentsOf the 13 included studies there were 14 groups whoreceived a MWMI and 11 no-treatment controlgroups Of these effect sizes were able to be calculatedfor nine intervention groups and seven control groups(Table III) Seven intervention groups had small to me-dium positive effects indicating successful weight loss(Brennan et al 2012 Croker et al 2012 Danielsenet al 2013 DeBar et al 2012 Lochrie et al 2013Lubans et al 2012 Nguyen Shrewsbury et al2012) and two intervention groups had no effect(Neumark-Sztainer et al 2010 Nguyen Shrewsburyet al 2012) All seven control groups showed no ef-fect on weight

Of the studies for which effect size could not be cal-culated the results were similar Mellin et al (1987)Morgan et al (2012) Sacher et al (2010) andWadden et al (1990) all observed significant weightloss following intervention Morgan et al (2012) andSacher et al (2010) also showed that these changeswere significantly different to changes observed in thecontrol groups No studies observed significant weightchange in the control groups

Correlation Between Self-Esteem Improvementand Weight Loss Effect SizesThere is a strong (rfrac14 641 R2frac140410) positive linearrelationship between effect sizes for self-esteem im-provement and weight loss across all intervention andcontrol groups (pfrac14 008)T

Quantitative Data AnalysisDifferences between intervention and control groupsfor change in self-esteem are presented in Figure 2aThis analysis included seven intervention groups(nfrac14 191) and seven control groups (nfrac14 132) with

interventions or intensive treatment phases rangingfrom 9 weeks to 6 months in duration A moderatelevel of the variation across studies was owing to het-erogeneity (I2frac14464 Higgins Thompson Deeksamp Altman 2003) The overall summary effect showed

no effect on self-esteem as a result of interventionSMD of 027 (95 confidence interval 004 059)zfrac14 169 and pfrac14 092 However all studies exceptone favored the intervention for improvements in self-esteem

The difference between intervention and controlgroups for change in BMI z-score is illustrated inFigure 2b This analysis included five interventiongroups (nfrac14 135) and five control groups (nfrac14 82) withinterventions ranging from 9 weeks to 6 months induration Heterogeneity in this sample was low(I2frac14177 Higgins et al 2003) and the overall sum-mary effect was 017 (022 011) BMI z-scorepoints (zfrac14613 and plt 001) indicating statisticallysignificant weight loss following MWMI

Discussion

The purpose of this review was to examine the effectof MWMIs on self-esteem in overweight and obeseadolescents Increased self-esteem is proposed as a keyfactor for maintaining long-term weight management(Elfhag amp Rossner 2005 French et al 1995Roberts 2006) A secondary outcome of this reviewwas to examine the impact of MWMIs on weight lossand whether this was associated with improvements inself-esteem

The meta-analysis showed no difference in self-esteem between the intervention and control groupsHowever six of the seven studies in the meta-analysisfavored the intervention over control for improve-ments in self-esteem and four of the six studies notincluded in the meta-analysis found significant im-provements in self-esteem following intervention Thelatter of these findings are similar to those of an earlierreview (Lowry et al 2007) that showed improve-ments in self-esteem following weight managementinterventions in a pediatric population particularlywhen certain intervention features were presentSimilarly a number of intervention features that con-tributed to an increased likelihood of improving self-esteem were identified in this review

Improvements in self-esteem regardless of weightloss have been demonstrated in children who tookpart in weight management interventions thatincluded a focus on building self-esteem and it is rec-ommended that this be a focus of all pediatric weightmanagement interventions (Lowry et al 2007) Yetthe majority of studies identified in this review did notinclude building self-esteem as a key aspect of theirintervention Nguyen Shrewsbury et al (2012)described the greatest focus on self-esteem (one75-min group session focused on building self-esteem)and also resulted in the largest treatment effect (057)and a significant improvement in self-esteem (NguyenShrewsbury et al 2012) A focus on similar topics

such as body image social support and managing bul-lying may also contribute to improvements in self-esteem (Croker et al 2012 Pierce amp Wardle 1997Tiggemann 2005) however these findings highlightthe lack of uptake of these recommendations

Among overweight and obese youth reductions inself-esteem are often observed in domains of physicalappearance and physical ability (Franklin DenyerSteinbeck Caterson amp Hill 2006 French et al1995 Latzer amp Stein 2013 Lowry et al 2007)Particularly for adolescent girls body image is a keyconcern (Cave Fildes Luckett amp Wearring 2015)and comprises a large portion of global self-esteem(Lowry et al 2007 Pesa Syre amp Jones 2000)However weight loss and associated changes in phys-ical appearance do not necessarily reflect improve-ments in self-esteem (Lowry et al 2007) Changes inbody-esteem often occur more rapidly than changes inglobal self-esteem as a result of weight management(Lowry et al 2007) This may explain the lack ofchange observed in global self-esteem in this meta-analysis and highlights the need to also include body-esteem (or physical self-esteem) as a focus and out-come of weight management interventions foradolescents

Parental involvement in adolescent weight manage-ment interventions is a critical component for success-ful weight loss and may also be important forimproving self-esteem (Lowry et al 2007) Weight-related teasing from family is shown to be negativelyassociated with self-esteem in overweight adolescentswhereas family connectedness was positively associ-ated with adolescent self-esteem (Fulkerson StraussNeumark-Sztainer Story amp Boutelle 2007) The in-clusion of parents in weight management interventionsfosters a safer and more encouraging home environ-ment for the adolescent (Lowry et al 2007) which isassociated with increased self-esteem in nonover-weight children (Marx amp Neumark-Sztainer 2005)All studies in the present review baring one includedparents in the intervention Parental involvementshould continue to be a key component of weightmanagement interventions to ensure a supportivehome environment for the adolescent to help fosterpositive self-esteem

Weight management interventions that used agroup setting to target self-esteem have shown im-provements in self-esteem without significant weightchange (Lowry et al 2007 Sherman AlexanderGomez Kim amp Marole 1992) The ability of the peergroup setting to provide opportunities for bondingsupport feelings of belonging development of peer-based skills and positive peer exchanges is key toincreasing self-esteem (Lowry et al 2007) The im-portance of this element is being acknowledged in the

field with all the studies in this review baring twousing group sessions in their intervention

Measures of self-esteem are self-reported and there-fore subjective Responses to questionnaires are likelyto be influenced by individual (eg age gender) andenvironmental (eg cultural group socioeconomicstatus) factors (Khanlou 2004) Changes followinginterventions may represent genuine long-termchanges in self-esteem or may be due to short-termfluctuations in self-esteem in response to specificevents (eg winning a sporting event or performanceon a test at school) (Kernis 1993) While validatedtools were used to measure self-esteem in all studies itwas difficult to conclude whether outcomes were en-tirely dependent on the intervention without inclusionof a no-treatment control group

The variety of self-esteem assessment tools also addsto the difficulty of interpretation Across the 13 studies inthis review five different tools were used with differentquestions and different scales Even within tools therewere different scales used to report the results (RosenbergSelf-esteem Scale) and different versions of the same ques-tionnaire (Harterrsquos Self-perception Profile for ChildrenHarterrsquos Self-perception Profile for Adolescents) HarterrsquosSelf-Perception Profile (Harterrsquos Self-perception Profilefor Adolescents for adolescents) which measures ninesubscales of self-esteem including physical self-esteem issuggested as the most appropriate measure for adolescentself-esteem (Lowry et al 2007) It was also the mostcommonly used tool among papers included in this re-view While Cohenrsquos d effect sizes were used to stand-ardize results in this review the consistent use of one toolwould provide the ability to compare raw self-esteemscores and create a stronger analysis in the future

Results from this review support evidence thatMWMIs induce weight loss in overweight and obeseadolescents (Hoelscher Kirk Ritchie ampCunningham-Sabo 2013 Kelly amp Melnyk 2008Luttikhuis et al 2009) The change in BMI z-score inthe present meta-analysis (017 [022 011]) wassimilar to the clinically meaningful weight loss re-ported in the 2009 Cochrane Review in children 12years at 6 months follow up from a lifestyle weightmanagement intervention (014 [017 012])(Luttikhuis et al 2009) Jelalian Mehlenbeck Lloyd-Richardson Birmaher and Wing (2006) and WalkerGately Bewick and Hill (2003) have demonstratedassociations between weight loss and increased self-esteem in overweight and obese adolescents after at-tending a weight-management intervention Similarlyin the present review a strong positive relationship be-tween treatment effects for weight loss and improve-ment in self-esteem was identified However itremains unclear whether the improvement in self-esteem was as a result of successful weight loss orwhether it was a contributing factor toward successful

weight loss Nonetheless building self-esteem shouldbe a key focus of MWMIs as improved self-esteem ap-

pears to be linked to enhanced weight lossA key strength of this review was that all included

studies had strong designs and presented level II evi-dence (Coleman et al 2009) However to further elu-

cidate the role of self-esteem in adolescent weightmanagement future research should consider power-

ing studies to detect changes in psychosocial as well asphysiological outcomes Only one study in this reviewwas powered to detect a change in psychosocial out-

comes (Daley et al 2006) which may explain thelack of significant results observed for self-esteem

Additionally a large number of included studies didnot describe their method of handling withdrawals or

use blinding to prevent the introduction of bias Toimprove confidence in the effectiveness of MWMIs

and reduce the risk of bias future studies should bedesigned with concealed allocation and document andreport in detail the flow of participants

Identification of intervention components that im-

prove self-esteem is important for future weight man-agement intervention design Included interventionswere heterogeneous offering different levels of diet-

ary physical activity and behavioral interventionwhich may have collectively or individually influenced

the results Inconsistent reporting of intervention andcomparator conditions make it difficult to elucidate

the components that contributed to improvements inself-esteem Future studies should report intervention

and comparator procedures in adequate detail so thatsuccessful components can be identified and repli-cated These limitations highlight areas for improve-

ment to develop best-practice guidelines forundertaking and evaluating MWMIs in adolescents to

enhance self-esteem

Conclusion

Overweight and obese adolescents experience low

self-esteem largely owing to poor body image yetthis meta-analysis found no improvement in self-esteem even with significant weight loss Although it

was noted that interventions that had larger effects onself-esteem also had larger effects on weight loss The

incorporation of intervention components that wereidentified to contribute to improvements in self-

esteem may assist future weight management interven-tions to improve the self-esteem of overweight and

obese adolescents Furthermore a consistent measureof self-esteem would enable easier interpretation ofself-esteem scores and comparison of results across

studies to improve our understanding of the relation-ship between self-esteem and weight management in

adolescents

Quantitative Data AnalysisDifferences between intervention and control groupsfor change in self-esteem are presented in Figure 2aThis analysis included seven intervention groups(nfrac14 191) and seven control groups (nfrac14 132) with

interventions or intensive treatment phases rangingfrom 9 weeks to 6 months in duration A moderatelevel of the variation across studies was owing to het-erogeneity (I2frac14464 Higgins Thompson Deeksamp Altman 2003) The overall summary effect showed

no effect on self-esteem as a result of interventionSMD of 027 (95 confidence interval 004 059)zfrac14 169 and pfrac14 092 However all studies exceptone favored the intervention for improvements in self-esteem

The difference between intervention and controlgroups for change in BMI z-score is illustrated inFigure 2b This analysis included five interventiongroups (nfrac14 135) and five control groups (nfrac14 82) withinterventions ranging from 9 weeks to 6 months induration Heterogeneity in this sample was low(I2frac14177 Higgins et al 2003) and the overall sum-mary effect was 017 (022 011) BMI z-scorepoints (zfrac14613 and plt 001) indicating statisticallysignificant weight loss following MWMI

Discussion

The purpose of this review was to examine the effectof MWMIs on self-esteem in overweight and obeseadolescents Increased self-esteem is proposed as a keyfactor for maintaining long-term weight management(Elfhag amp Rossner 2005 French et al 1995Roberts 2006) A secondary outcome of this reviewwas to examine the impact of MWMIs on weight lossand whether this was associated with improvements inself-esteem

The meta-analysis showed no difference in self-esteem between the intervention and control groupsHowever six of the seven studies in the meta-analysisfavored the intervention over control for improve-ments in self-esteem and four of the six studies notincluded in the meta-analysis found significant im-provements in self-esteem following intervention Thelatter of these findings are similar to those of an earlierreview (Lowry et al 2007) that showed improve-ments in self-esteem following weight managementinterventions in a pediatric population particularlywhen certain intervention features were presentSimilarly a number of intervention features that con-tributed to an increased likelihood of improving self-esteem were identified in this review

Improvements in self-esteem regardless of weightloss have been demonstrated in children who tookpart in weight management interventions thatincluded a focus on building self-esteem and it is rec-ommended that this be a focus of all pediatric weightmanagement interventions (Lowry et al 2007) Yetthe majority of studies identified in this review did notinclude building self-esteem as a key aspect of theirintervention Nguyen Shrewsbury et al (2012)described the greatest focus on self-esteem (one75-min group session focused on building self-esteem)and also resulted in the largest treatment effect (057)and a significant improvement in self-esteem (NguyenShrewsbury et al 2012) A focus on similar topics

such as body image social support and managing bul-lying may also contribute to improvements in self-esteem (Croker et al 2012 Pierce amp Wardle 1997Tiggemann 2005) however these findings highlightthe lack of uptake of these recommendations

Among overweight and obese youth reductions inself-esteem are often observed in domains of physicalappearance and physical ability (Franklin DenyerSteinbeck Caterson amp Hill 2006 French et al1995 Latzer amp Stein 2013 Lowry et al 2007)Particularly for adolescent girls body image is a keyconcern (Cave Fildes Luckett amp Wearring 2015)and comprises a large portion of global self-esteem(Lowry et al 2007 Pesa Syre amp Jones 2000)However weight loss and associated changes in phys-ical appearance do not necessarily reflect improve-ments in self-esteem (Lowry et al 2007) Changes inbody-esteem often occur more rapidly than changes inglobal self-esteem as a result of weight management(Lowry et al 2007) This may explain the lack ofchange observed in global self-esteem in this meta-analysis and highlights the need to also include body-esteem (or physical self-esteem) as a focus and out-come of weight management interventions foradolescents

Parental involvement in adolescent weight manage-ment interventions is a critical component for success-ful weight loss and may also be important forimproving self-esteem (Lowry et al 2007) Weight-related teasing from family is shown to be negativelyassociated with self-esteem in overweight adolescentswhereas family connectedness was positively associ-ated with adolescent self-esteem (Fulkerson StraussNeumark-Sztainer Story amp Boutelle 2007) The in-clusion of parents in weight management interventionsfosters a safer and more encouraging home environ-ment for the adolescent (Lowry et al 2007) which isassociated with increased self-esteem in nonover-weight children (Marx amp Neumark-Sztainer 2005)All studies in the present review baring one includedparents in the intervention Parental involvementshould continue to be a key component of weightmanagement interventions to ensure a supportivehome environment for the adolescent to help fosterpositive self-esteem

Weight management interventions that used agroup setting to target self-esteem have shown im-provements in self-esteem without significant weightchange (Lowry et al 2007 Sherman AlexanderGomez Kim amp Marole 1992) The ability of the peergroup setting to provide opportunities for bondingsupport feelings of belonging development of peer-based skills and positive peer exchanges is key toincreasing self-esteem (Lowry et al 2007) The im-portance of this element is being acknowledged in the

field with all the studies in this review baring twousing group sessions in their intervention

Measures of self-esteem are self-reported and there-fore subjective Responses to questionnaires are likelyto be influenced by individual (eg age gender) andenvironmental (eg cultural group socioeconomicstatus) factors (Khanlou 2004) Changes followinginterventions may represent genuine long-termchanges in self-esteem or may be due to short-termfluctuations in self-esteem in response to specificevents (eg winning a sporting event or performanceon a test at school) (Kernis 1993) While validatedtools were used to measure self-esteem in all studies itwas difficult to conclude whether outcomes were en-tirely dependent on the intervention without inclusionof a no-treatment control group

The variety of self-esteem assessment tools also addsto the difficulty of interpretation Across the 13 studies inthis review five different tools were used with differentquestions and different scales Even within tools therewere different scales used to report the results (RosenbergSelf-esteem Scale) and different versions of the same ques-tionnaire (Harterrsquos Self-perception Profile for ChildrenHarterrsquos Self-perception Profile for Adolescents) HarterrsquosSelf-Perception Profile (Harterrsquos Self-perception Profilefor Adolescents for adolescents) which measures ninesubscales of self-esteem including physical self-esteem issuggested as the most appropriate measure for adolescentself-esteem (Lowry et al 2007) It was also the mostcommonly used tool among papers included in this re-view While Cohenrsquos d effect sizes were used to stand-ardize results in this review the consistent use of one toolwould provide the ability to compare raw self-esteemscores and create a stronger analysis in the future

Results from this review support evidence thatMWMIs induce weight loss in overweight and obeseadolescents (Hoelscher Kirk Ritchie ampCunningham-Sabo 2013 Kelly amp Melnyk 2008Luttikhuis et al 2009) The change in BMI z-score inthe present meta-analysis (017 [022 011]) wassimilar to the clinically meaningful weight loss re-ported in the 2009 Cochrane Review in children 12years at 6 months follow up from a lifestyle weightmanagement intervention (014 [017 012])(Luttikhuis et al 2009) Jelalian Mehlenbeck Lloyd-Richardson Birmaher and Wing (2006) and WalkerGately Bewick and Hill (2003) have demonstratedassociations between weight loss and increased self-esteem in overweight and obese adolescents after at-tending a weight-management intervention Similarlyin the present review a strong positive relationship be-tween treatment effects for weight loss and improve-ment in self-esteem was identified However itremains unclear whether the improvement in self-esteem was as a result of successful weight loss orwhether it was a contributing factor toward successful

weight loss Nonetheless building self-esteem shouldbe a key focus of MWMIs as improved self-esteem ap-

pears to be linked to enhanced weight lossA key strength of this review was that all included

studies had strong designs and presented level II evi-dence (Coleman et al 2009) However to further elu-

cidate the role of self-esteem in adolescent weightmanagement future research should consider power-

ing studies to detect changes in psychosocial as well asphysiological outcomes Only one study in this reviewwas powered to detect a change in psychosocial out-

comes (Daley et al 2006) which may explain thelack of significant results observed for self-esteem

Additionally a large number of included studies didnot describe their method of handling withdrawals or

use blinding to prevent the introduction of bias Toimprove confidence in the effectiveness of MWMIs

and reduce the risk of bias future studies should bedesigned with concealed allocation and document andreport in detail the flow of participants

Identification of intervention components that im-

prove self-esteem is important for future weight man-agement intervention design Included interventionswere heterogeneous offering different levels of diet-

ary physical activity and behavioral interventionwhich may have collectively or individually influenced

the results Inconsistent reporting of intervention andcomparator conditions make it difficult to elucidate

the components that contributed to improvements inself-esteem Future studies should report intervention

and comparator procedures in adequate detail so thatsuccessful components can be identified and repli-cated These limitations highlight areas for improve-

ment to develop best-practice guidelines forundertaking and evaluating MWMIs in adolescents to

enhance self-esteem

Conclusion

Overweight and obese adolescents experience low

self-esteem largely owing to poor body image yetthis meta-analysis found no improvement in self-esteem even with significant weight loss Although it

was noted that interventions that had larger effects onself-esteem also had larger effects on weight loss The

incorporation of intervention components that wereidentified to contribute to improvements in self-

esteem may assist future weight management interven-tions to improve the self-esteem of overweight and

obese adolescents Furthermore a consistent measureof self-esteem would enable easier interpretation ofself-esteem scores and comparison of results across

studies to improve our understanding of the relation-ship between self-esteem and weight management in

adolescents

Discussion

The purpose of this review was to examine the effectof MWMIs on self-esteem in overweight and obeseadolescents Increased self-esteem is proposed as a keyfactor for maintaining long-term weight management(Elfhag amp Rossner 2005 French et al 1995Roberts 2006) A secondary outcome of this reviewwas to examine the impact of MWMIs on weight lossand whether this was associated with improvements inself-esteem

The meta-analysis showed no difference in self-esteem between the intervention and control groupsHowever six of the seven studies in the meta-analysisfavored the intervention over control for improve-ments in self-esteem and four of the six studies notincluded in the meta-analysis found significant im-provements in self-esteem following intervention Thelatter of these findings are similar to those of an earlierreview (Lowry et al 2007) that showed improve-ments in self-esteem following weight managementinterventions in a pediatric population particularlywhen certain intervention features were presentSimilarly a number of intervention features that con-tributed to an increased likelihood of improving self-esteem were identified in this review

Improvements in self-esteem regardless of weightloss have been demonstrated in children who tookpart in weight management interventions thatincluded a focus on building self-esteem and it is rec-ommended that this be a focus of all pediatric weightmanagement interventions (Lowry et al 2007) Yetthe majority of studies identified in this review did notinclude building self-esteem as a key aspect of theirintervention Nguyen Shrewsbury et al (2012)described the greatest focus on self-esteem (one75-min group session focused on building self-esteem)and also resulted in the largest treatment effect (057)and a significant improvement in self-esteem (NguyenShrewsbury et al 2012) A focus on similar topics

such as body image social support and managing bul-lying may also contribute to improvements in self-esteem (Croker et al 2012 Pierce amp Wardle 1997Tiggemann 2005) however these findings highlightthe lack of uptake of these recommendations

Among overweight and obese youth reductions inself-esteem are often observed in domains of physicalappearance and physical ability (Franklin DenyerSteinbeck Caterson amp Hill 2006 French et al1995 Latzer amp Stein 2013 Lowry et al 2007)Particularly for adolescent girls body image is a keyconcern (Cave Fildes Luckett amp Wearring 2015)and comprises a large portion of global self-esteem(Lowry et al 2007 Pesa Syre amp Jones 2000)However weight loss and associated changes in phys-ical appearance do not necessarily reflect improve-ments in self-esteem (Lowry et al 2007) Changes inbody-esteem often occur more rapidly than changes inglobal self-esteem as a result of weight management(Lowry et al 2007) This may explain the lack ofchange observed in global self-esteem in this meta-analysis and highlights the need to also include body-esteem (or physical self-esteem) as a focus and out-come of weight management interventions foradolescents

Parental involvement in adolescent weight manage-ment interventions is a critical component for success-ful weight loss and may also be important forimproving self-esteem (Lowry et al 2007) Weight-related teasing from family is shown to be negativelyassociated with self-esteem in overweight adolescentswhereas family connectedness was positively associ-ated with adolescent self-esteem (Fulkerson StraussNeumark-Sztainer Story amp Boutelle 2007) The in-clusion of parents in weight management interventionsfosters a safer and more encouraging home environ-ment for the adolescent (Lowry et al 2007) which isassociated with increased self-esteem in nonover-weight children (Marx amp Neumark-Sztainer 2005)All studies in the present review baring one includedparents in the intervention Parental involvementshould continue to be a key component of weightmanagement interventions to ensure a supportivehome environment for the adolescent to help fosterpositive self-esteem

Weight management interventions that used agroup setting to target self-esteem have shown im-provements in self-esteem without significant weightchange (Lowry et al 2007 Sherman AlexanderGomez Kim amp Marole 1992) The ability of the peergroup setting to provide opportunities for bondingsupport feelings of belonging development of peer-based skills and positive peer exchanges is key toincreasing self-esteem (Lowry et al 2007) The im-portance of this element is being acknowledged in the

field with all the studies in this review baring twousing group sessions in their intervention

Measures of self-esteem are self-reported and there-fore subjective Responses to questionnaires are likelyto be influenced by individual (eg age gender) andenvironmental (eg cultural group socioeconomicstatus) factors (Khanlou 2004) Changes followinginterventions may represent genuine long-termchanges in self-esteem or may be due to short-termfluctuations in self-esteem in response to specificevents (eg winning a sporting event or performanceon a test at school) (Kernis 1993) While validatedtools were used to measure self-esteem in all studies itwas difficult to conclude whether outcomes were en-tirely dependent on the intervention without inclusionof a no-treatment control group

The variety of self-esteem assessment tools also addsto the difficulty of interpretation Across the 13 studies inthis review five different tools were used with differentquestions and different scales Even within tools therewere different scales used to report the results (RosenbergSelf-esteem Scale) and different versions of the same ques-tionnaire (Harterrsquos Self-perception Profile for ChildrenHarterrsquos Self-perception Profile for Adolescents) HarterrsquosSelf-Perception Profile (Harterrsquos Self-perception Profilefor Adolescents for adolescents) which measures ninesubscales of self-esteem including physical self-esteem issuggested as the most appropriate measure for adolescentself-esteem (Lowry et al 2007) It was also the mostcommonly used tool among papers included in this re-view While Cohenrsquos d effect sizes were used to stand-ardize results in this review the consistent use of one toolwould provide the ability to compare raw self-esteemscores and create a stronger analysis in the future

Results from this review support evidence thatMWMIs induce weight loss in overweight and obeseadolescents (Hoelscher Kirk Ritchie ampCunningham-Sabo 2013 Kelly amp Melnyk 2008Luttikhuis et al 2009) The change in BMI z-score inthe present meta-analysis (017 [022 011]) wassimilar to the clinically meaningful weight loss re-ported in the 2009 Cochrane Review in children 12years at 6 months follow up from a lifestyle weightmanagement intervention (014 [017 012])(Luttikhuis et al 2009) Jelalian Mehlenbeck Lloyd-Richardson Birmaher and Wing (2006) and WalkerGately Bewick and Hill (2003) have demonstratedassociations between weight loss and increased self-esteem in overweight and obese adolescents after at-tending a weight-management intervention Similarlyin the present review a strong positive relationship be-tween treatment effects for weight loss and improve-ment in self-esteem was identified However itremains unclear whether the improvement in self-esteem was as a result of successful weight loss orwhether it was a contributing factor toward successful

weight loss Nonetheless building self-esteem shouldbe a key focus of MWMIs as improved self-esteem ap-

pears to be linked to enhanced weight lossA key strength of this review was that all included

studies had strong designs and presented level II evi-dence (Coleman et al 2009) However to further elu-

cidate the role of self-esteem in adolescent weightmanagement future research should consider power-

ing studies to detect changes in psychosocial as well asphysiological outcomes Only one study in this reviewwas powered to detect a change in psychosocial out-

comes (Daley et al 2006) which may explain thelack of significant results observed for self-esteem

Additionally a large number of included studies didnot describe their method of handling withdrawals or

use blinding to prevent the introduction of bias Toimprove confidence in the effectiveness of MWMIs

and reduce the risk of bias future studies should bedesigned with concealed allocation and document andreport in detail the flow of participants

Identification of intervention components that im-

prove self-esteem is important for future weight man-agement intervention design Included interventionswere heterogeneous offering different levels of diet-

ary physical activity and behavioral interventionwhich may have collectively or individually influenced

the results Inconsistent reporting of intervention andcomparator conditions make it difficult to elucidate

the components that contributed to improvements inself-esteem Future studies should report intervention

and comparator procedures in adequate detail so thatsuccessful components can be identified and repli-cated These limitations highlight areas for improve-

ment to develop best-practice guidelines forundertaking and evaluating MWMIs in adolescents to

enhance self-esteem

Conclusion

Overweight and obese adolescents experience low

self-esteem largely owing to poor body image yetthis meta-analysis found no improvement in self-esteem even with significant weight loss Although it

was noted that interventions that had larger effects onself-esteem also had larger effects on weight loss The

incorporation of intervention components that wereidentified to contribute to improvements in self-

esteem may assist future weight management interven-tions to improve the self-esteem of overweight and

obese adolescents Furthermore a consistent measureof self-esteem would enable easier interpretation ofself-esteem scores and comparison of results across

studies to improve our understanding of the relation-ship between self-esteem and weight management in

adolescents

The variety of self-esteem assessment tools also addsto the difficulty of interpretation Across the 13 studies inthis review five different tools were used with differentquestions and different scales Even within tools therewere different scales used to report the results (RosenbergSelf-esteem Scale) and different versions of the same ques-tionnaire (Harterrsquos Self-perception Profile for ChildrenHarterrsquos Self-perception Profile for Adolescents) HarterrsquosSelf-Perception Profile (Harterrsquos Self-perception Profilefor Adolescents for adolescents) which measures ninesubscales of self-esteem including physical self-esteem issuggested as the most appropriate measure for adolescentself-esteem (Lowry et al 2007) It was also the mostcommonly used tool among papers included in this re-view While Cohenrsquos d effect sizes were used to stand-ardize results in this review the consistent use of one toolwould provide the ability to compare raw self-esteemscores and create a stronger analysis in the future

Results from this review support evidence thatMWMIs induce weight loss in overweight and obeseadolescents (Hoelscher Kirk Ritchie ampCunningham-Sabo 2013 Kelly amp Melnyk 2008Luttikhuis et al 2009) The change in BMI z-score inthe present meta-analysis (017 [022 011]) wassimilar to the clinically meaningful weight loss re-ported in the 2009 Cochrane Review in children 12years at 6 months follow up from a lifestyle weightmanagement intervention (014 [017 012])(Luttikhuis et al 2009) Jelalian Mehlenbeck Lloyd-Richardson Birmaher and Wing (2006) and WalkerGately Bewick and Hill (2003) have demonstratedassociations between weight loss and increased self-esteem in overweight and obese adolescents after at-tending a weight-management intervention Similarlyin the present review a strong positive relationship be-tween treatment effects for weight loss and improve-ment in self-esteem was identified However itremains unclear whether the improvement in self-esteem was as a result of successful weight loss orwhether it was a contributing factor toward successful

Overweight and obese adolescents experience low

self-esteem largely owing to poor body image yetthis meta-analysis found no improvement in self-esteem even with significant weight loss Although it

Page 12: Systematic Review and Meta-Analysis: The Impact of ...people.uncw.edu/hakanr/documents/weightlossandselfesteem.pdf · (French, Story, & Perry, 1995; Strauss, 2000). During adolescence,

no effect on self-esteem as a result of interventionSMD of 027 (95 confidence interval 004 059)zfrac14 169 and pfrac14 092 However all studies exceptone favored the intervention for improvements in self-esteem

The difference between intervention and controlgroups for change in BMI z-score is illustrated inFigure 2b This analysis included five interventiongroups (nfrac14 135) and five control groups (nfrac14 82) withinterventions ranging from 9 weeks to 6 months induration Heterogeneity in this sample was low(I2frac14177 Higgins et al 2003) and the overall sum-mary effect was 017 (022 011) BMI z-scorepoints (zfrac14613 and plt 001) indicating statisticallysignificant weight loss following MWMI

Discussion

The purpose of this review was to examine the effectof MWMIs on self-esteem in overweight and obeseadolescents Increased self-esteem is proposed as a keyfactor for maintaining long-term weight management(Elfhag amp Rossner 2005 French et al 1995Roberts 2006) A secondary outcome of this reviewwas to examine the impact of MWMIs on weight lossand whether this was associated with improvements inself-esteem

The meta-analysis showed no difference in self-esteem between the intervention and control groupsHowever six of the seven studies in the meta-analysisfavored the intervention over control for improve-ments in self-esteem and four of the six studies notincluded in the meta-analysis found significant im-provements in self-esteem following intervention Thelatter of these findings are similar to those of an earlierreview (Lowry et al 2007) that showed improve-ments in self-esteem following weight managementinterventions in a pediatric population particularlywhen certain intervention features were presentSimilarly a number of intervention features that con-tributed to an increased likelihood of improving self-esteem were identified in this review

Improvements in self-esteem regardless of weightloss have been demonstrated in children who tookpart in weight management interventions thatincluded a focus on building self-esteem and it is rec-ommended that this be a focus of all pediatric weightmanagement interventions (Lowry et al 2007) Yetthe majority of studies identified in this review did notinclude building self-esteem as a key aspect of theirintervention Nguyen Shrewsbury et al (2012)described the greatest focus on self-esteem (one75-min group session focused on building self-esteem)and also resulted in the largest treatment effect (057)and a significant improvement in self-esteem (NguyenShrewsbury et al 2012) A focus on similar topics

such as body image social support and managing bul-lying may also contribute to improvements in self-esteem (Croker et al 2012 Pierce amp Wardle 1997Tiggemann 2005) however these findings highlightthe lack of uptake of these recommendations

Among overweight and obese youth reductions inself-esteem are often observed in domains of physicalappearance and physical ability (Franklin DenyerSteinbeck Caterson amp Hill 2006 French et al1995 Latzer amp Stein 2013 Lowry et al 2007)Particularly for adolescent girls body image is a keyconcern (Cave Fildes Luckett amp Wearring 2015)and comprises a large portion of global self-esteem(Lowry et al 2007 Pesa Syre amp Jones 2000)However weight loss and associated changes in phys-ical appearance do not necessarily reflect improve-ments in self-esteem (Lowry et al 2007) Changes inbody-esteem often occur more rapidly than changes inglobal self-esteem as a result of weight management(Lowry et al 2007) This may explain the lack ofchange observed in global self-esteem in this meta-analysis and highlights the need to also include body-esteem (or physical self-esteem) as a focus and out-come of weight management interventions foradolescents

Parental involvement in adolescent weight manage-ment interventions is a critical component for success-ful weight loss and may also be important forimproving self-esteem (Lowry et al 2007) Weight-related teasing from family is shown to be negativelyassociated with self-esteem in overweight adolescentswhereas family connectedness was positively associ-ated with adolescent self-esteem (Fulkerson StraussNeumark-Sztainer Story amp Boutelle 2007) The in-clusion of parents in weight management interventionsfosters a safer and more encouraging home environ-ment for the adolescent (Lowry et al 2007) which isassociated with increased self-esteem in nonover-weight children (Marx amp Neumark-Sztainer 2005)All studies in the present review baring one includedparents in the intervention Parental involvementshould continue to be a key component of weightmanagement interventions to ensure a supportivehome environment for the adolescent to help fosterpositive self-esteem

Weight management interventions that used agroup setting to target self-esteem have shown im-provements in self-esteem without significant weightchange (Lowry et al 2007 Sherman AlexanderGomez Kim amp Marole 1992) The ability of the peergroup setting to provide opportunities for bondingsupport feelings of belonging development of peer-based skills and positive peer exchanges is key toincreasing self-esteem (Lowry et al 2007) The im-portance of this element is being acknowledged in the

Page 13: Systematic Review and Meta-Analysis: The Impact of ...people.uncw.edu/hakanr/documents/weightlossandselfesteem.pdf · (French, Story, & Perry, 1995; Strauss, 2000). During adolescence,

field with all the studies in this review baring twousing group sessions in their intervention

Measures of self-esteem are self-reported and there-fore subjective Responses to questionnaires are likelyto be influenced by individual (eg age gender) andenvironmental (eg cultural group socioeconomicstatus) factors (Khanlou 2004) Changes followinginterventions may represent genuine long-termchanges in self-esteem or may be due to short-termfluctuations in self-esteem in response to specificevents (eg winning a sporting event or performanceon a test at school) (Kernis 1993) While validatedtools were used to measure self-esteem in all studies itwas difficult to conclude whether outcomes were en-tirely dependent on the intervention without inclusionof a no-treatment control group

The variety of self-esteem assessment tools also addsto the difficulty of interpretation Across the 13 studies inthis review five different tools were used with differentquestions and different scales Even within tools therewere different scales used to report the results (RosenbergSelf-esteem Scale) and different versions of the same ques-tionnaire (Harterrsquos Self-perception Profile for ChildrenHarterrsquos Self-perception Profile for Adolescents) HarterrsquosSelf-Perception Profile (Harterrsquos Self-perception Profilefor Adolescents for adolescents) which measures ninesubscales of self-esteem including physical self-esteem issuggested as the most appropriate measure for adolescentself-esteem (Lowry et al 2007) It was also the mostcommonly used tool among papers included in this re-view While Cohenrsquos d effect sizes were used to stand-ardize results in this review the consistent use of one toolwould provide the ability to compare raw self-esteemscores and create a stronger analysis in the future

Results from this review support evidence thatMWMIs induce weight loss in overweight and obeseadolescents (Hoelscher Kirk Ritchie ampCunningham-Sabo 2013 Kelly amp Melnyk 2008Luttikhuis et al 2009) The change in BMI z-score inthe present meta-analysis (017 [022 011]) wassimilar to the clinically meaningful weight loss re-ported in the 2009 Cochrane Review in children 12years at 6 months follow up from a lifestyle weightmanagement intervention (014 [017 012])(Luttikhuis et al 2009) Jelalian Mehlenbeck Lloyd-Richardson Birmaher and Wing (2006) and WalkerGately Bewick and Hill (2003) have demonstratedassociations between weight loss and increased self-esteem in overweight and obese adolescents after at-tending a weight-management intervention Similarlyin the present review a strong positive relationship be-tween treatment effects for weight loss and improve-ment in self-esteem was identified However itremains unclear whether the improvement in self-esteem was as a result of successful weight loss orwhether it was a contributing factor toward successful

weight loss Nonetheless building self-esteem shouldbe a key focus of MWMIs as improved self-esteem ap-

pears to be linked to enhanced weight lossA key strength of this review was that all included

studies had strong designs and presented level II evi-dence (Coleman et al 2009) However to further elu-

cidate the role of self-esteem in adolescent weightmanagement future research should consider power-

ing studies to detect changes in psychosocial as well asphysiological outcomes Only one study in this reviewwas powered to detect a change in psychosocial out-

comes (Daley et al 2006) which may explain thelack of significant results observed for self-esteem

Additionally a large number of included studies didnot describe their method of handling withdrawals or

use blinding to prevent the introduction of bias Toimprove confidence in the effectiveness of MWMIs

and reduce the risk of bias future studies should bedesigned with concealed allocation and document andreport in detail the flow of participants

Identification of intervention components that im-

prove self-esteem is important for future weight man-agement intervention design Included interventionswere heterogeneous offering different levels of diet-

ary physical activity and behavioral interventionwhich may have collectively or individually influenced

the results Inconsistent reporting of intervention andcomparator conditions make it difficult to elucidate

the components that contributed to improvements inself-esteem Future studies should report intervention

and comparator procedures in adequate detail so thatsuccessful components can be identified and repli-cated These limitations highlight areas for improve-

ment to develop best-practice guidelines forundertaking and evaluating MWMIs in adolescents to

enhance self-esteem

Conclusion

Overweight and obese adolescents experience low

self-esteem largely owing to poor body image yetthis meta-analysis found no improvement in self-esteem even with significant weight loss Although it

was noted that interventions that had larger effects onself-esteem also had larger effects on weight loss The

incorporation of intervention components that wereidentified to contribute to improvements in self-

esteem may assist future weight management interven-tions to improve the self-esteem of overweight and

obese adolescents Furthermore a consistent measureof self-esteem would enable easier interpretation ofself-esteem scores and comparison of results across

studies to improve our understanding of the relation-ship between self-esteem and weight management in

adolescents
