ABSTRACT

Sarcopenia is a progressive skeletal muscle disorder associated with poor health outcomes such as falls, fractures, cardiovascular and metabolic disease. In this study, we used nation-wide data from 2008 to 2011 Korea National Health and Nutrition Examination Survey (KNHANES) to analyze the association between bone mineral density (BMD) and sarcopenia in community-dwelling men and women. Subjects with history of medication for osteoporosis or with illness or malignancy affecting bone metabolism were excluded. Sarcopenia was defined using the revised Asian Working Group for Sarcopenia (AWGS) classification with SMI (skeletal muscle index; <7.0 kg/m2 for men and <5.4 kg/m2 for women). We included 2,133 subjects aged 50 years or older men (N=1,246) and postmenopausal women (N=887). Prevalence of sarcopenia was significantly higher in men (28.8%) than women (22.0%). In multiple regression analysis, sarcopenia was significantly associated with low bone mass at the lumbar spine, femur neck and total femur BMD after adjusting confounding factors in men. However, there was no association between sarcopenia and bone mass in women. In conclusion, sarcopenia is significantly related to low bone mass, especially in men aged ≥50 years in Korea.
