Implication of Sarcopenia and XXXX on Lung Function in Healthy Elderly: Using Korean National Health and Nutrition Examination Survey.

Previous studies have demonstrated a positive association between @entity28 and @entity6314 . However, the effect of muscle and fat has not been fully assessed, especially in a healthy elderly population. In this study, we evaluated the impact of low muscle mass (LMM) and LMM with @entity28 on @entity358 in healthy elderly subjects. Our study used data from the Korea National Health and Nutrition Examination Survey from 2008 to 2011. @entity1 and @entity1 aged 65 yr or older were included. Muscle mass was measured by dual-energy X-ray absorptiometry. LMM was defined as two standard deviations below the sex-specific mean for young healthy adults. Obesity was defined as body mass index >=  25 kg/m(2). The prevalence of LMM in individuals aged over 65 was 11.9%. LMM and pulmonary function (forced vital capacity and forced expiratory volume in 1 second) were independently associated after adjusting for age, sex, body mass index, smoking status, @entity285 consumption, and frequency of exercise. LMM with @entity28 was also related to a decrease in pulmonary function. This study revealed that LMM is an independent risk factor of decreased pulmonary function in healthy Korean @entity1 and @entity1 over 65 yr of age.
