Objective : The purpose of this study is to determine the incidence of osteoporosis according to lean mass, waist circumference, waist-hip ratio, body mass index, and sleep duration in postmenopausal women over 50 years of age. Methods : The participants of the study were 1,320 postmenopausal women over 50 years of age among those who participated in the 6th community survey of the Korean Genome and Epidemiology Study. Logistic regression analysis was conducted after correcting the characteristic variables affecting osteoporosis to find out the relationship between independent variables and the occurrence of osteoporosis. Statistical significance in the analysis was set at the significance level of less than 0.05. Results : As a result of logistic regression analysis, the risk of osteoporosis decreased by 0.06 times for every 1kg increase in lean body mass. Waist circumference showed an odds ratio of 0.69 (95% CI: 0.53∼0.88) compared to waist circumferences greater than 85 cm than those less than 85 cm. The risk of osteoporosis related to abdominal fat percentage was 0.76 lower in the group with abdominal fat percentage higher than 0.90 than in the group with lower than 0.90, with an odds ratio of 0.76 (95% CI: 0.06∼0.96). Body mass index (BMI) was odds ratio of 0.70 (95% CI: 0.56∼0.89) compared to BMI 25 or more compared to BMI less than 25. As for the sleep duration, the odds ratio of 5 hours or less compared to 6∼7 hours increased the risk of osteoporosis by 1.39 times with an odds ratio of 1.39 (95% CI: 1.05∼1.84), and the odds ratio of 8 hours or more compared to 6∼7 hours of sleep duration increased the odds ratio of 0.77 (95% CI: 0.56 ∼1.06). Conclusion : In this study, it is confirmed that lean mass, waist circumference, waist-hip ratio, body mass index, sleep duration are related with osteoporosis. In order to help prevent the onset of osteoporosis in postmenopausal women over 50 years of age, comprehensive preventive management, including individual appropriate sleep duration and management of lean mass, waist circumference, and BMI levels, is required before osteoporosis evolved.
