신체활동량을 기준으로 한 폐경 후 여성에게 있어 근력운동 실시유무에 따른 골밀도 관련 요인, 골밀도 및 골다공증 비교 연구

Abstract

The purpose of this study is to compare the problems of bone in postmenopausal women who have different physical activity and muscle strength exercise using Korea National Health and Nutrition Examination Survey (KNHNES) data. Complex sampling design data was obtained from the fourth (2008-2009) and fifth (2010-2011) KNHNES. The subjects, total 3,307 postmenopausal women excluding those who were in the menopause over 20 years, were classified into six groups based on physical activity and muscle strength exercise. Data were analyzed by complex sample linear model, chi-squared analysis and logistic regression. All statistical significance levels were set to .05. The results of this study are as follows. 1) Height, AUDIT, protein consumption and calcium consumption of people who did muscle strength exercise in moderate physical activity (MM) group were significantly higher than those with no muscle strength exercise in moderate physical activity (MN) group. Also age and menopause period of MM group was significantly lower than MN group. 2) The difference of body meneral density (BMD) in MM group was significantly higher than MN group. 3) The prevalence of osteopenia and osteoporosis in all of muscle strength exercise group was lower than non-muscle strength exercise group. 4) The prevalence of osteoporosis in MN group was significantly higher than MM group. In summary, the MM group has positive effects on the influencing factors of bone mineral density (BMD), BMD and osteoporosis compared with other groups.
