【摘要】：目的研究仫佬族绝经前与绝经后女性体成分和骨密度的相关关系,探讨体成分的变化对骨密度的影响。方法随机选取广西仫佬族成年女性200名,追溯其三代均为仫佬族,应用TANITA-MC180人体成分分析仪测定其肌肉量、脂肪量等体成分指标,采用SONOT3000超声骨密度仪测定其右侧跟骨的骨硬度指数。结果 (1)绝经前女性的体重、去脂体重、肌肉量、皮下脂肪量、躯干脂肪量、四肢肌肉量、推定骨量、骨硬度指数和T值等均显著高于绝经后女性(P0.01);而绝经前女性的内脏脂肪面积、腰臀比显著低于绝经后女性(P0.01)。(2)绝经前女性和绝经后女性的骨质疏松检出率分别为6%和45%,差异具有统计学意义(P0.01)。(3)相关分析发现肌肉量、四肢肌肉量和躯干肌肉量与骨密度之间存在显著的正相关关系(P0.01或P0.05),而当控制年龄和绝经状态后体成分和骨密度之间没有相关性;根据年龄分组后发现,≥50岁组的肌肉量各指标与骨密度存在较显著的关联(P0.05),而50岁组的体成分与骨密度不存在关联性(P0.05)。(4)多重逐步回归分析发现只有绝经状态、躯干肌肉量和内脏脂肪量与骨密度相关,而躯干肌肉量对骨密度影响最大。结论仫佬族绝经后女性的骨质疏松症发生率显著高于绝经前女性;控制年龄和绝经因素后,只有躯干肌肉量与骨密度较显著相关,结果可为骨质疏松症的预防和诊断提供理论依据。
[Abstract]:Objective to study the correlation between body composition and bone mineral density (BMD) in premenopausal and postmenopausal women of Mulao nationality, and to explore the effect of changes of body composition on BMD. Methods 200 adult women of Mulao nationality in Guangxi were randomly selected and their three generations were all of Mulao nationality. TANITA-MC180 body composition analyzer was used to measure the muscle mass, fat content and other body composition indexes, and the bone hardness index of the right calcaneus was measured by SONOT3000 ultrasound bone mineral density instrument. Results 1) the body weight, fat free body weight, muscle volume of premenopausal women were measured by SONOT3000 ultrasound absorptiometry. The subcutaneous fat volume, trunk fat volume, limb muscle volume, presumed bone mass, bone hardness index and T value were significantly higher than those of postmenopausal women (P 0.01), while the visceral fat area of premenopausal women was significantly higher than that of postmenopausal women. The prevalence of osteoporosis in premenopausal women and postmenopausal women was significantly lower than that in postmenopausal women (6% and 45, respectively, P < 0.01). There was a significant positive correlation between limb muscle volume and trunk muscle volume and bone mineral density (P 0.01 or P 0.05), but there was no correlation between body composition and bone mineral density (BMD) after control of age and menopausal status. There was a significant correlation between muscle mass and BMD in 鈮，
