中老年妇女骨质疏松症的流行病学调查

目的调查河北省承德地区健康中老年妇女腰椎骨密度（BMD）的年龄变化规律及各年龄段骨质疏松患病率的年龄分布情况。方法采用美国GELUNAR公司的enCORE2007双能X线骨密度仪对561名健康中老年妇女进行腰椎骨密度测量。结果河北省承德地区中老年妇女腰椎骨密度值从40-44岁组的1．178g／cm。下降到75岁以上组的0．795g／cm^2。40岁以上开始出现骨量减少，50岁以上开始出现骨质疏松；骨质疏松的患病率从50-75岁平均约为10．27％。结论中老年妇女骨质疏松患病率随年龄的增加而增加，骨密度检测可早期诊断无症状的骨质疏松症。

Epidemiological survey on mid-aged and older females'OP in Chengde Heber Province

Objective We aim to find the lumbar tendency because of aging and the distribution of OP incidence a-mong different age groups by examining a number of healthy mid-aged and senile females＇ BMD in Chengde area. Methods Using enCORE 2007 dual energy X-ray bone density instrument produced by American GE LUNAR company, we carried on lumbar BMD examination among 561 mid-aged and senile females in Chengde area. Result The lumbar density of these females decreases from 1. 178 g/cm^2 in group 40-44 to 0. 795 g/cm^2 in group 75 and older. The bone density begins to reduce from 40 and older, and OP occurs at 50 and older. The average OP incidence is 10.27% in group 50-75. Conclusion The OP incidence among the mid-aged and older females increases with age, meanwhile, the incidence in group 50-54 and group 65-69 increases remarkably compared with group 45-49 and group 60-64.
