广西少数民族成年女性骨密度的差异及年龄变化特点

目的探讨广西毛南族、仫佬族、瑶族和苗族成年女性骨密度和骨质疏松症患病率(POP)的差异及年龄变化规律。方法随机抽取广西毛南族、仫佬族、瑶族、苗族成年女性860例,通过定量超声骨密度仪测定其右侧跟骨的骨密度。结果毛南族、仫佬族和苗族女性间的骨质指数(BQI)、T值和POP差异无统计学意义,而瑶族女性与以上3个民族女性间的差异显著(P <0. 05);随年龄增长,瑶族和毛南族的骨密度在35~45岁年龄段达到峰值后急剧下降,仫佬族和苗族在45岁之前,骨密度变化趋势平缓,在45岁后急剧下降;在45~55岁年龄段,瑶族女性的BQI和T值显著大于毛南族、仫佬族和苗族女性(P <0. 05);在45~55岁年龄段,瑶族女性的POP显著低于毛南族、仫佬族和苗族女性,而其他3个民族女性间的POP差异无统计学意义。结论广西成年女性的骨密度和骨质疏松症患病率各民族间的差异存在显著的统计学意义,瑶族女性的骨质状况较好。

Prevalence rate of osteoporosis in the mid-aged and elderly in selected parts of China

OBJECTIVE: To understand the distribution of prevalence rate of osteoporosis in the middle - aged and elderly in parts of China.
