The risk factors to influence postmenopausal osteoporosis on women living in Suzhou district

目的分析苏州地区绝经后妇女的骨质疏松发生情况及相关影响因素。方法采用随机整群抽样方法从苏州市抽取261例45-70岁的绝经后妇女进行流行病学调查,收集相关资料,测定桡骨远端骨密度,分析骨质疏松患病情况及其影响因素。结果 261例中,骨质疏松92例（35.25%）（A组）,骨量减少117例（44.83%）（B组）,骨量正常52例（19.92%）（C组）。A组的绝经年限、分娩次数、腰围、腰臀比（WHR）、胆固醇、甘油三酯、低密度脂蛋白等指标均高于B、C组（P〈0.05）。绝经年限（OR=2.29）和WHR（OR=3.79）是骨质疏松的危险因素（P〈0.01）。结论绝经时间长、中心性肥胖和多产妇女是骨质疏松的高风险人群。
