目的:讨论围绝经期与绝经早期妇女骨密度(BMD)和身体成分的变化,分析身体成分对BMD的影响。方法:选择2009年10月以来在本院行健康体检的(40～60)岁围绝经期和绝经≤5年的妇女,记录身高和体质量,计算体质数(BMI)。采用双能X线检测仪检测腰椎2～4和左侧股骨颈、大转子及全髋的BMD。结果:符合条件的妇女共157例,其中围绝经期组69例,绝经早期组88例。绝经早期组身高低于围绝经期组,体质量和BMI高于围绝经期组,绝经早期组腰椎2～4、股骨颈、大转子、全髋BMD均低于围绝经期组。结论:绝经早期的BMD降低。绝经后骨质疏松预防工作应及早展开。
OBJECTIVE: To discuss the change of bone mineral density (BMD) and body composition in perimenopausal women and early menopause women and to analyze the influence of body composition on BMD. Methods: Women with perimenopausal menopause (≤40-60) years and menopausal ≤5 years who had taken physical examination in our hospital since October 2009 were enrolled in the study. Height and body mass were recorded and body mass index (BMI) was calculated. Dual energy X-ray detector was used to detect BMD of lumbar spine 2 ~ 4 and left femoral neck, greater trochanter and total hip. Results: A total of 157 eligible women, including 69 cases of perimenopausal group, 88 cases of early menopause. Compared with the perimenopausal group, body mass and BMI in the early menopause group were lower than those in the perimenopausal group. The lumbar spine 2 to 4 and the femoral neck, greater trochanter, and total hip BMD in the early menopause group were lower than those in the perimenopausal group. Conclusion: BMD decreased in early menopause. Prevention of postmenopausal osteoporosis should be started as soon as possible.
