Résumé
BACKGROUND: Physical activity is an important factor for preventing osteoporosis. This study aimed to investigate the association of work- and leisure-time physical activities with osteoporosis in postmenopausal women.METHODS: Data were obtained from the Korea National Health and Nutritional Examination Survey 2015–2016. A total of 2,885 postmenopausal women were included in the analysis. The subjects were divided into 3 groups according to the intensity of the work- and leisure-time physical activities. T-test, chi-square test, and multivariable logistic regression analysis were used.RESULTS: No association was found between work-time physical activity and osteoporosis prevalence. However, a dose-response relationship was found in case of leisure-time physical activity. People with leisure-time physical activity of at least >1,000 MET-min/week showed lower prevalence of osteoporosis.CONCLUSION: An appropriate level of leisure-time physical activity should be recommended to prevent and treat osteoporosis.
