摘要

The purpose of this study was to determine the relationship of physical activities with bone mineral density (BMD) in postmenopausal women. Through dual energy X-ray absorptiometry (DEXA) measurements, 102 women with BMD more than one standard deviation below (T-score ＜ -1.0 SD) were grouped as osteopenia group (average age 54.5 ± 4.90/yrs), 41 women with BMD less than one standard deviation below (T-score ＞ -1.0 SD) grouped as healthy group (average age 53.7 ± 4.47/yrs) were included in this study. Age, height, body weigh, body mass index (BMI), duration of menopause and calcium intake were testified with t-test for both groups and showed only significantly difference in body weight. Considering hormone status and calcium intake were critical to BMD, together with body weight, we put them as covariance. Physical activities, BMD, and bone resorption marker (assessed by urinary N-telopoptides (NTx)) were analyzed with MANCOVA. The results showed physical activities was significantly lower and NTx significantly higher in osteopenia group (p＜0.05). It is our recommendation that womankind should increase regular physical activities to benefit bone mineral density.
