Sarcopenia Definitions

• Sarcopenia is operationally defined as a lean body mass more than 2 standard deviations below the young normal mean

– Baumgartner RN, et al. Mech Ageing Dev. 1999;107:123

• Reduction of muscle mass and strength that occurs with aging (may be independent of mass)

– Lauretani F, et al. J Appl Physiol 2003;95:1851

• Sarcopenia is defined as the loss of muscle protein mass, function and quality that accompanies advancing age.

– Zinna EM, et al. Cur Opinion Clin Nutr Metabolic Care 2003;61:87

From  ages 20‐80 

The cumulative decline in muscle mass reaches 40% 

By 70 yrs

Muscle accounts for only ~27% of total body wt  

From  ages 30‐60

Gains ∼500 g of fat, loses ∼250 g of muscle every yr

Loss of Muscle, Gain of Fat

• Obesity was strongly associated w/ self-reported physical functional health, equivalent to being 11 yrs older for men & 16 yrs for women

• Associated w/ poorer functional status & independent predictor of survival

• Sarcopenic obesity was predictive of morbidity & mortality in both malignant & non-malignant disease (Honda et al 2007; Prado et al 2008).

• Unintentional wt loss >10 lbs lost in the last year

• Exhaustion, Poor endurance

• Low levels of physical activity

• Low walking speed

• Muscle weakness (grip strength)

Screening for Sarcopenia: Measuring Physical Function

Decreased grip strength orChair stand (time to rise from a seated position 5X) orDifficulty walking ¼ mile or Climbing 10 steps without resting

Grip strength is a powerful predictor of future mortality

Effect of Aging on Energy Intake and Expenditure 

Decrease in total energy expenditure (TEE)

• RMR= 70% of TEE

• Thermic effect of food= 10%

• Physical activity= 20%

Elia M, Ritz P, Stubbs RJ. Total energy expenditure in the elderly. Eur J Clin Nutr 2000;54(suppl):S92–103.

• RMR  2‐3% every decade after 20

• Majority of decline is loss of fat free mass(FFM)

• Thermic effect of food= 20% lower in older men than younger 

• physical activity accounts for 50% of  in TEE

Hormonal Changes

Aging is associated with a decrease in growth hormone secretion, decline in serum testosterone and resistance to leptin leading to:• Decrease in FFM • Increase in fat mass• Decreased ability to down‐regulate appetite

Matsumoto AM. Andropause: clinical implications of the decline in serum testosterone levels with aging in men. J Gerontol A Biol Sci Med  ci 2002;57:M76–99.Moller N, O’Brien P, Nair KS. Disruption of the relationship between fat content and leptin levels with aging in humans. J Clin Endocrinol Metab 1998;83:931– 4.

Quality of Life

• Nurses’ Health Study: BMI & age inversely associated with physical function, pain issues and limitations due to physical problems

• SF- 36 noted obesity is associated with health related QOL for older adults- physical functioning and limitations

Weight Loss Alone

Positive• Decrease fat mass/ lean body mass

• Young adults 75% loss is fat tissue & 25% FFM, similar in older adults

• 5‐10% weight loss can improve metabolic abnormalities including insulin‐resistant metabolism

Negative• Could exacerbate age‐related loss of muscle mass & sarcopenia

Dengel DR, Hagberg JM, Coon PJ, Drinkwater DT, Goldberg AP.Effects of weight loss by diet alone or combined with aerobic exercise on body composition in older obese men. Metabolism 1994;43:867‐71.141.

Weight Change in Older Adults

If weight is lost, it is primarily LBM

If weight is gained, it is primarily fat

Therefore, weight loss, even when subsequently 

corrected, is a risk factor for sarcopenia

Newman AB et al. Am J Clin Nutr 2005;82:872-878

Benefits of Exercise + Diet

• RCT of obese older adults found no substantial difference in loss of FFM following a 10% weight loss diet & exercise vs. control who did not lose wt

• Regular exercise can decrease diet induced  only loss of FFM

loss and exercise on frailty in obese elderly subjects. J Am Geriatr Soc

2005;53:S16(abstr).

• Moderate weight loss + exercise improves both physical function and health‐related QOL

• Can result in improved insulin sensitivity and decrease in intrahepatic fat

Weight Loss & Bone Mineral Density

• Women 32‐72  total BMD of 1‐2%/ wt. loss of 10%

• Bone loss proportional to amount of wt. loss 

• Wt loss alters plasma concentration of hormones involved in bone metabolism & markers of bone turnover

Weight Loss + Exercise & BMD

• RCT ‐30 obese older adults of diet vs. diet & exercise = loss of muscle mass & muscle strength

• RCT‐ 27 obese older adults of diet vs diet & exercise=bone mineral density but not in spine

• RCT‐107= improved function but loss of LBM & hip BMD suggesting need for Ca & D or anti‐resorptive therapy during wt. loss (Villareal 2012)

• Essential for maintaining muscle mass & function in aging people

• Helps preserve the Type II muscle fibers that are prone to atrophy in the elderly

Vitamin D

Montero‐Odasso et al. 2005

Vitamin D Supplements

Sarcopenia Recommendations for Vitamin D

• 25(OH) Vit D levels should be measured in all sarcopenic patients (A)

• Vit D supplementation in doses sufficient to raise levels above 100 nmol/L should be given as an adjunctive therapy (A)

• Either Vit D2 or D3 is an acceptable replacement (A)

• Doses of 50,000 IU of Vit D a wk are safe (A)

Level A= minimum of single randomized placebo control trial or meta‐analysis Source: Nutritional recommendations for the management of sarcopenia for the Society for Sarcopenia, Cachexia and Wasting Disease. Morely et.al J Am Med. Dir Assoc: 2010; 11:391‐396.

Carefully weigh risk vs benefits of weight loss plans

Is weight loss appropriate for all obese  individuals with sarcopenia? 

Will a restricted diet reduce the individual’s ability to 

consume adequate nutrients to maintain health?

What are the risks associated with 

obesity treatment?

Weight Loss Therapy

Moderate energy deficient diet plan

• focus on high quality protein

• consider vitamin/mineral

supplements

Increase physical activity

Weight Loss Therapy

Behavior & cognitive strategies

• problem solving

• goal setting

• social support

• self-monitoring

• stress management

• relapse prevention

Nutrition Assessment• Food and Nutrition Related History: food intake, food availability, physical activity, nutrition QOL, meds ,herbal supplements ,previous diets 

• Anthropometric Measurements: weight history, BMI

• Biochemical Values: glucose, electrolytes, any relevant tests

• Nutrition‐Focused Physical Findings: physical appearance, chewing, swallowing concerns, 

• Client History: age ,gender, race, socioeconomic status, support system,

Estimating Energy  Requirements

• RMR= Indirect calorimetry (IC) is most accurate

• Mifflin‐St.Jeor most accurate when IC not an option

• Use ABW + activity and/or injury factor

Academy of Nutrition and Dietetics. AND Evidence Analysis Library.

• Example: 78 year old male. 5’ 10” and 360 lbs. BMI 51.65 obese class III,  moderate activity level

• 2830 kcalories/day

• Minus 500‐700 kcalories to lose 1‐2 lbs./week

Gradual loss has been tied to protein deficiency, lack of exercise, & increased 

frailty among the elderly

The human body reacts to protein deficiency by taking AA away from muscle 

tissue & other areas of the body

The process, in which the body basically metabolizes itself (catabolism) can lead to 

muscle loss & weakness

Protein +  Exercise  Sarcopenia

Ensure Adequate Protein Intake

15%‐38% of older men eat less than the RDI for protein.

27%‐41% of older women eat less than  the RDI for protein.

Morley J et. al. Nutritional recommendations for the management of sarcopenia J Am Med Dir 2010;11:391‐396.

Factors Influencing Protein Intake in Older Adults1. Inadequate intake= appetite loss or GI disturbances

2. Reduced ability to utilize available protein=insulin resistance, protein anabolic resistance, immobility

3. Increased need for protein= inflammatory disease, increased oxidative modification of protein, catabolic conditions ass. /acute & chronic diseases

All Lead to Loss of Functionality

Evidence‐Based recommendations for optimal dietary protein intake in older people: a Position Paper from the PROT‐AGE Study Group, JAMDA 2013

What Does the Evidence Suggest for Optimal Protein Intake for Older Adults 

• Positive association between protein ingestion & muscle mass (PORT‐AGE study group JAMDA 2013)

• Protein  spread equally between breakfast lunch and dinner (Paddon‐

Jones 2009)

• If needed, additional protein supplementation should given between meals (Wilson MM 2002)

Improves muscle mass

Bone health

Insulin sensitivity

Modulates inflammation

Protein Intake Great than RDA

Health, Aging, and Body Composition Study

• Assessed association between dietary protein intake and changes in LBM over 3 years

• 2056 healthy older adults

• Food frequency questionnaire & measured changes in LBM  using DEXA

• Adjusted for potential confounders such as smoking, physical activity 

• Participants / highest quintile of protein intake lost approx. 40% less LBM than those in lowest quintile of intake

Ensure Adequate Protein Intake

It is recommended that the total protein intakeshould be 1 to 1.5 g/kg/day (B) It is suggested that a leucine-enriched balance

essential amino acid mix may be added to thediet (B)

Level B= Small trials Source: Nutritional recommendations for the management of sarcopenia for the Society for Sarcopenia, Cachexia and Wasting Disease. Morely E et.al J Am Med. Dir Assoc: 2010; 11:391‐

396. 

Role of Essential Amino Acids

• Primary source of protein stimulus

• Leucine maybe the most effective & a determinant of quality

• Consumption of leucine‐rich protein sources may be a key strategy that helps prevent/delay sarcopenia

Combaret et al., 2005

Antioxidants

• Aging is associated with increased levels of oxidative stress leading to damaged cell membranes & proteins responsible for many chronic diseases resulting from an inability of the immune response to initiate an adequate cellular defense.  

• Oxidative stress has also been implicated in sarcopenia

• Antioxidants are effective in combating oxidative damage

Antioxidants

Antioxidants• Low serum selenium concentrations are associated with poor grip 

strength among older women living in the community

• Low serum selenium resulted in increased IL(6) = low physical function & sarcopenia (Beck 2007, Lauretani 2007)

• Dietary carotenoids comprise an important component of the antioxidant defense system that helps keep the inflammatory cytokines in check

• There is evidence that older adults with low plasma carotenoids levels are more likely to have elevated IL‐6 concentrations, poor muscle strength

Richard D. Semba*, Fulvio Lauretani, and Luigi Ferrucc. Carotenoids as protection against sarcopenia in older adults. Arch Biochem Biophys. 2007 February 15; 458(2): 141–145h.

• The 6 major dietary carotenoids (α‐carotene, β‐carotene, β‐cryptoxanthin, lutein, zeaxanthin, and lycopene) comprise an important component of the antioxidant defense system in humans

• Carotenoids protect against oxidative stress by quenching singlet oxygen, scavenging free radicals, inhibiting lipid peroxidation, & modulate proinflammatory cytokines

Semba RD, Blaum , Guralnik JM, et al. Carotenoid and vitamin E status are associated with indicators of sarcopenia 

among older women living in the community. Aging Clin Exp Res. 2003;15:482‐487

Carotenoids

Carotenoids

Studies suggest intake of carotenoids or carotenoid‐rich foods may be protective against decline in muscle strength & developing walking disability among older community‐dwelling adults

• EPA (eicosapentaenoic acid) has been found to preserve muscle mass under various physiological conditions.

• DHA (docosahexaenoic acid) has anti‐inflammatory effects, which scientists believe may be of value in managing sarcopenia.

Omega‐3 fatty acid

Tisdale 2006; Roubenoff 2003; Fritsche 2006

Suggested Diet Plan

• Focus on carbohydrate and high quality protein distributed evenly between meals(1.0‐1.5 gr/kg/day)

• Encourage consumption of sources of Ca/vit D

• Consider vitamin D supplement

• Include fruits/veggies antioxidants 

Incorporate Exercise

Summary• Assess all obese older adults with sarcopenia to determine if weight loss is appropriate

• Initiate exercise  for all sarcopenic older adults

• Weight loss programs should include an exercise component (aerobic & resistance training)  plus behavior modification, self‐monitoring, goal setting and social support

Summary

• Weight loss should be gradual and meals should include high quality protein consumed in equal quantities at each meal

• Consider leucine, antioxidants, vit D, & omega‐3 fatty acids
