成都地区中老年女性骨折危险因素调查

Investigation of fracture risk factors in middle-aged and old women in Chengdu

目的对成都地区中老年女性骨折分布特征和易发因素进行相关性分析,探讨中老年女性骨折危险因素。方法选择成都市某社区55～75岁女性为调查对象,以问卷调查、体格检查和DXA测量BMD值等方法,分析骨折的相关危险因素。结果共调查绝经后妇女340人,其中发生骨折108例,骨折发生率为31.76%。成都地区中老年女性骨折的发生率随绝经年龄的增长而降低,绝经年龄早、生育胎数多、哺乳时间长、体重指数高是骨折的重要危险因素。进食足量肉食、长期饮用牛奶、右手握力大对骨折有保护作用。结论成都地区中老年女性骨折发生率较高,需引起社会关注,建议加大力度改善骨折的预防、检测和治疗状况。
