目的了解上海北蔡镇老年人群骨密度(Bone mineraldensity,BMD)变化规律及骨质疏松(Osteoporosis,OP)患病率,为本地区骨质疏松症的防治提供参考。方法使用美国GE公司的LunarProdigy Advance PA+300164型双能X线骨密度仪对608例上海北蔡镇60～79岁老年人正位腰椎和左股骨近端进行骨密度测定,男性205例,女性403例。结果随着年龄的增加髋部BMD逐渐下降,而腰部BMD不随年龄的增加而下降。男性组与女性组OP患病率差异有显著性(P<0.001);60～64、65～69、70～74、75～79岁组OP患病率差异有显著性(P<0.05)。结论上海北蔡镇老年人群OP患病率随年龄增高而增高,70～79岁女性骨质疏松的患病率最高,预防骨折的重点在老年妇女。老年人应坚持适当的体育活动,及时检查骨密度,积极治疗骨质疏松症,并注意防止跌倒导致的骨折发生。
