“…Interestingly, the variation in ASM values in young and old men was greater than in women, whereas variation in values for intra-abdominal obesity indicators between young and old subjects was greater in women than in men. When the alternative definitions of SO suggested by Zoico et al 9 and Davison et al 10 were used, the prevalence of SO in this study was higher than that of SO in Davison's study. Moreover, the cutoff values for sarcopenia and obesity used in this study differed from those of earlier studies.…”

“…9,10 SO was defined as high total body fat percentage and low relative skeletal muscle mass in the same subjects according to other earlier studies. [8][9][10] We classified four sarcopenia/ obesity groups by using the new criterion of SMI of two s.d. below the value of a young reference group and the upper two quintiles for total body fat percentage.…”

“…6,8 In community-dwelling elderly women in Verona, Italy, Zoico et al, 9 defining SO as the two lower quintiles of ASM/height 2 plus two higher quintiles of fat mass, reported that the prevalence of SO was 12.4%. Using the same definition, Davison et al 10 reported that the prevalence of SO was 9.6% in men and 7.4% in women from the bioelectrical impedance analysis data of NHANES III. The ASM/height 2 index is highly correlated with body mass index (BMI) as a current criterion for obesity.…”

Objectives: To examine the prevalence of sarcopenia and sarcopenic obesity (SO) as defined by different indices, including appendicular skeletal muscle mass (ASM)/height 2 , skeletal muscle mass index (SMI) and residuals for Korean adults, and to explore the association between SO and metabolic syndrome. Methods: Our study sample included 526 participants (328 women, 198 men) for whom complete data on body composition were collected using available dual X-ray absorptiometry. Modified National Cholesterol Education Program Adult Treatment Panel III criteria were used to identify the individuals with metabolic syndrome. Results: The prevalence of sarcopenia and SO is higher in older adults. Using two s.d. of ASM/height 2 below reference values from young, healthy adults as a definition of sarcopenia, the prevalence of sarcopenia and SO was 6.3% and 1.3% in older (X60 years) men and 4.1% and 0.8% in older women, respectively. The prevalence of sarcopenia using the residuals method was 15.4% in older men and 22.3% in older women. In addition, using two s.d. of SMI, the prevalence of sarcopenia and SO was 5.1% and 5.1%, respectively, in older men and 14.2% and 12.5%, respectively, in older women. Among women, SO subjects defined by the SMI had three times the risk of metabolic syndrome (odds ratios (OR) ¼ 3.24, 95% confidence interval (CI) ¼ 1.21-8.66) and non-sarcopenic obese subjects had approximately twice the risk of metabolic syndrome (OR ¼ 2.17, 95% CI ¼ 1.22-3.88) compared with normal subjects. Similar trends were observed in men. Conclusion: The prevalence and cutoff values of sarcopenia and SO in the Korean population were evaluated using different methods. Among the different indices of sarcopenia and SO, SO only defined using the SMI was associated with the risk of metabolic syndrome. As the Korean population gets older and more obese, the problematics of SO need to be elucidate.

“…However, others have not found an association between sarcopenic obesity and functional limitations. 30,31 In the Health ABC cohort, Visser et al 32 previously examined the cross-sectional association between muscle mass, muscle composition and total body fat with physical performance and found that muscle mass and muscle attenuation were positively associated with physical performance while total body fat was inversely associated with physical performance. Muscle mass was most strongly associated with physical performance in men, whereas total body fat was most strongly associated with physical performance in women.…”

Objective: Although the association between current obesity and physical disability is well known, the cumulative effect of obesity is unknown. Using data from the Health, Aging and Body Composition study, we examined the association between weight history in young and middle adulthood and weight status in late adulthood with physical performance in late adulthood. Design: Longitudinal cohort study. Subjects: White and black men and women aged 70-79 years at study baseline (n ¼ 2803). Measures: Body mass index (BMI; kg/m 2 ) was calculated using recalled height at age 25 and weight at age 25 and 50 and measured height and weight at ages 70-79. Physical performance at ages 70-79 was assessed using a short physical performance battery (SPPB) and a 400-m walk test. Results: In this well-functioning cohort, approximately 24% of men and 8% of women reported being overweight or obese (BMI X25 kg/m 2 ) at age 25, 51% of men and 37% of women reported being overweight or obese at age 50, and 69% of men and 66% of women were overweight or obese at ages 70-79. Men and women who were obese (BMI X30 kg/m 2 ) at ages 25, 50 and 70-79 had significantly worse SPPB scores and 400-m walk times than those who were normal weight. Women who were overweight (BMI 25-29.9 kg/m 2 ) at ages 25, 50 and 70-79 also had significantly worse physical performance. Furthermore, men and women who had a history of being overweight or obese at ages 25 or 50 had worse physical performance compared to those who were normal weight throughout or who were overweight or obese at ages 70-79 but not in midlife or earlier.Conclusions: Maintaining a healthy body weight throughout adulthood may play a role in preventing or delaying the onset of physical disability.

Background: Obesity exacerbates the age-related decline in physical function and causes frailty in older persons. However, appropriate treatment for obese older persons is unknown. We evaluated the effects of weight loss and exercise therapy on physical function and body composition in obese older persons. Methods:We screened 40 obese older volunteers and eventually randomized 27 frail obese older volunteers to treatment or control groups. Treatment consisted of 6 months of weekly behavioral therapy for weight loss in conjunction with exercise training 3 times per week. Physical function was evaluated with measurements of frailty (Physical Performance Test, peak oxygen consumption, and Functional Status Questionnaire); strength, gait, and balance tests; body composition with dualenergy x-ray absorptiometry; and quality of life using the Medical Outcomes Survey 36-Item Short-Form Health Survey. Results are reported as mean ± SD.Results: Two subjects in the treatment group did not comply with the intervention, and 1 subject in the control group withdrew. Analyses included all 27 subjects originally randomized to the treatment and control groups. The treatment group lost 8.4% ± 5.6% of body weight, whereas weight did not change in the control group (ϩ0.5% ± 2.8%; PϽ.001). Compared with the control group, fat mass decreased (−6.6 ± 3.4 vs ϩ1.7 ± 4.1 kg; PϽ.001), without a change in fat-free mass (−1.2±2.1 vs −1.0±3.5 kg; P =.75) in the treatment group. The Physical Performance Test score (2.6±2.5 vs 0.1±1.0; P=.001), peak oxygen consumption (1.7±1.6 vs 0.3±1.1 mL/min per kilogram; P =.02), and Functional Status Questionnaire score (2.9±3.7 vs −0.2±3.9; P =.02) improved in treated subjects compared with control subjects. Treatment also improved strength, walking speed, obstacle course, 1-leg limb stance time, and health survey physical subscale scores (all PϽ.05). Conclusion:These findings suggest that weight loss and exercise can ameliorate frailty in obese older adults.
