Abstract
Sarcopenia is believed to be associated with disability and metabolic complications. The objective of this study was to examine the metabolic and quality-of-life profile of sarcopenic overweight and obese postmenopausal women. In this cross-sectional study of 136 healthy overweight and obese postmenopausal women, 9 class I sarcopenic women were identified. Class I sarcopenia was defined as an appendicular lean body mass index (ALBMI) <or= 6.44 kg.m(-2) (appendicular lean body mass/height). Outcome measures were body composition (dual energy X-ray absorptiometry and computed tomography), blood lipids, inflammation markers, blood pressure, insulin sensitivity (homeostasis model assessment and hyperinsulinemic-euglycemic clamp), cardiorespiratory fitness, and quality of life (Medical Outcomes Study General Health Survey questionnaire). By design, class I sarcopenic women (n = 9) had a significantly lower ALBMI and appendicular lean body mass than nonsarcopenic women (n = 127). In addition, class I sarcopenic women tended to have lower levels of insulin resistance (p = 0.070) and fasting glucose (p = 0.054). However, no difference between the groups was observed for quality of life. This study showed that, in our sample of class I sarcopenic overweight and obese postmenopausal women, subjects did not present an unfavourable metabolic or quality-of-life profile, compared with nonsarcopenic overweight and obese postmenopausal women.
