Objectives

Increase awareness on childhood obesity among pediatricians so they can work with their patients and parents to identify at-risk patients and take preventive or corrective action.

TM

Childhood Obesity Epidemic – Widespread in population (adults and

children) Progressive – Childhood obesity becomes adult

obesity Alters Development – Physically, emotionally,

psychosocially Chronic disease – Lifelong morbidity accelerates

“adult” disease into childhood Increases morbidity/mortality – First generation to

have shorter lifespan than parents

TM

Obesity and Normal Development Deconditioned Derailed from normal activity Depressed, teased and bullied Disease burden Decreased quality of life Diminished educational and job opportunities

Trends in Obesity Among Childrenand Adolescents: United States, 1963–2008

Note: Obesity is defined as body mass index (BMI) greater than or equal to sex- and age-specific 95th percentile from the 2000 CDC Growth Charts.CDC/NCHS, National Health Examination Surveys II (ages 6–11), III (ages 12–17), and National Health and Nutrition ExaminationSurveys (NHANES) 1999–2000, 2001–2003, 2003–2004, 2005–2006, and 2007–2008.

Recommendations with Consistent Evidence Multiple studies show consistent association

between recommended behavior and either obesity risk or energy balance.– Limit consumption of sugar sweetened beverages. – Limit TV (0 hours <2 years, <2 hours >2 years old).– Remove TV from primary sleeping area.– Eat breakfast daily. – Limit eating out. – Encourage family meals. – Limit portion size.

TM

Recommendations with Mixed Evidence

Some studies demonstrated evidence for weight or energy balance benefit but others did not or the studies were too few or too small. – 5 or more fruits and vegetable servings/day (9 age

appropriate servings recommended)

TM

Recommendations Where Evidence Suggests Studies have not examined association with weight

or energy balance, or the studies were too few or too small, but expert committee thinks it could support healthy weight and would not be harmful – Eat a diet rich in calcium.– Eat a diet high in fiber. – Eat a diet with balanced macronutrients (food groups). – Breastfeeding– Promote moderate-vigorous activity 60 minutes a day.– Limit consumption of energy dense foods.

TM

Assessment of Obesity Calculate, chart, and classify BMI for all children 2–18

years of age at least yearly. Assess dietary patterns. Assess activity/inactivity. Assess readiness for change. Assess obesity related comorbidities. Assess ongoing progress.

TM

BMI – Calculate, Chart, Classify• BMI is a screening measure, determines further

evaluation• BMI based on age and gender and is a population

based reference• Underweight BMI <5% • “Normal weight” BMI 5%–84% • Overweight BMI >85%–94% (IOM classification)• Obese BMI 95%–99% (IOM classification)• Morbid (severe) obesity BMI >99%

TM

Prevention All children are considered “at risk for obesity.” Message at well visits– Simple– Consistent– Cumulative prevention

“Gateway message” to nutrition, activity, and high risk behavior

Promote breastfeeding. Diet and physical activity

• 5 or more servings of fruits and vegetables per day • 2 or fewer hours of screen time per day, and no television

in the room where the child sleeps • 1 hour or more of daily physical activity • No sugar-sweetened beverages

Prevention of BMI 5%–84%

TM

Prevention BMI 5%–84% Portions

– Age appropriate– “Parents provide, child decides”– 10–15 minute increments of exercise

Structure– Breakfast– Family dinners, no TV– Limit fast food– Outdoor time

Balance– Food groups– Limit refined sugar– Screen time alternatives

TM

PreventionMinimum Once a Year at Well Visits Self-efficacy and readiness to change Small incremental steps for change Family support Positive Self monitoring Setbacks are normal, trouble shoot, support return to plan Identify high risk nutritional/activity behaviors

TM

Universal Assessment of Obesity Risk: Steps to Prevention and Treatment

American Academy of Pediatrics. Pediatric Obesity Clinical Decision Support Chart.Elk Grove Village, IL: American Academy of Pediatrics; 2008.

TM

Prevention Plus BMI >85% Build on prevention. Eating behaviors – Family meals should happen at least 5 to 6 times per

week. – Allow the child to self-regulate his or her meals and

avoid overly restrictive behaviors—“Parents provide, child decides.”

– Structure activity.

TM

Prevention Plus BMI >85% Within this category, the goal should be weight

maintenance with growth that results in a decreasing BMI as age increases.

Monthly follow-up for 3 to 6 months; if no improvement go to Stage 2.

TM

Assess Dietary Patterns Additional practices to be considered for evaluation

during the qualitative dietary assessment include: – Excessive consumption of foods that are high in energy

density – Meal frequency and snacking patterns (including quality)

TM

Dietary Assessment Consumption of sugar sweetened beverages Daily breakfast Eating out Family meals Portion size 5 or more servings of fruits and vegetables Calcium Fiber Balanced macronutrients (food groups) Energy dense foods Readiness to change

TM

Assess Physical Activity/Inactivity Screen time TV in room Daily activity Self-efficacy and readiness to change Physical (built) environment Social/community support for activity Barriers to physical activity Assess patient’s and family’s activity and exercise

habits. Assess outdoor activity.

TM

Physical Activity/Inactivity Advise 60 minutes of at least moderate physical

activity per day and 20 minutes of vigorous activity 3 times a week.– Refer to community activity programs.– Encourage development of family activities.– Consider pedometer use.

Decrease level of sedentary behavior. Limit screen time to <2 hours per day. No TV/computer in bedroom.

TM

Structured Weight Management Dietary and physical activity behaviors – Development of a plan for utilization of a balanced

macronutrient diet emphasizing low amounts of energy-dense foods

– Increased structured daily meals and snacks – Supervised active play of at least 60 minutes a day – Screen time of 1 hour or less a day

TM

Structured Weight Management Increased monitoring (eg, screen time, physical

activity, dietary intake, restaurant logs) by provider, patient, and/or family

This approach may be amenable to group visits with patient/parent component, nutrition, and structured activity.

TM

Structured Weight Management Weight maintenance that – Decreases BMI as age and height increases

Weight loss should not exceed – 1 lb/month in children aged 2–11 yearsor– An average of 2 lb/week in older overweight/obese

children and adolescents If no improvement in BMI/weight after 3 to 6

months, patient should be advanced to Stage 3.

TM

Family History Focused family history– Obesity, type 2 diabetes, cardiovascular disease

(particularly hypertension), and early deaths from heart disease or stroke

Family history may be the touch point for emphasizing family involvement.

Medical Screening by BMI Category

TM

Comprehensive Multidisciplinary Protocol Multidisciplinary obesity care team– Physician, nurse, dietician, exercise trainer, social worker,

psychologist Eating and activity goals are the same as in Stage 2. Activities within this category should also include: – Structured behavioral modification program, including

food and activity monitoring and development of short-term diet and physical activity goals

TM

Comprehensive MultidisciplinaryProtocol Behavior modification – Involvement of primary caregivers/families in children

under age 12 years – Training of primary caregivers/families for all children

Goal – Weight maintenance or gradual weight loss until BMI is

<85th percentile and should not exceed 1 lb/month in children aged 2–5 years, or 2 lb/week in older obese children and adolescents

TM

Tertiary Care Protocol Referral to pediatric tertiary weight management

center with access to a multidisciplinary team with expertise in childhood obesity and which operates under a designed protocol

Continued diet and activity counseling and the consideration of such additions as meal replacement, very-low-calorie diet, medication, and surgery

TM

Partnership with Families Families have a critical role in influencing a child’s

health. Effective interaction with families is the cornerstone

of lifestyle change.

TM

Communication Positive discussion of what healthy lifestyle changes

families can make (evidence base) Allow for personal family choices. Have families set specific achievable goals and follow

up with these on revisits. Be aware of cultural norms, significance of meals and

eating for family/community, beliefs about special foods, and feelings about body size.

Motivational interviewing
