福建省中老年人骨密度的流行病学调查

Epidemkllogical investigation of bone mineral density in norml middle-aged and old people in Fujian Province

目的 了解福建省正常中老年人骨密度的水平和特点,为本地区骨质疏松症的防治提供参考。方法应用双能X线骨密度仪(DEXA)对福建省福州、泉州、龙岩3个地区共计2643例中老年人腰椎及股骨近端进行骨密度测定。结果 中老年人随着年龄的增加,各部位的BMD逐渐下降,女性更为明显,尤其是50岁左右绝经后妇女更加突出,50岁以后女性BND低于男性。结论 OP的防治重点应放在50岁女性;测定的腰椎BMD与临床情况不相符时,应参考股骨近端的BMD进行诊断;福建省中老年人应每天进行适当的体育活动,维持骨密度,抑制骨丢失,预防OP的发生。

Objective To evaluate bone mineral density of normal middle-aged and old people in Fujian Province, providing useful data for preventing osteoporosis (OP) . Methods BMD of lumbar spines and proximal femur were measured by dual energy X-ray absorptiometry (DEXA) for 2643 healthy middle-aged and old persons in Fuzhou, Quanzhou and Longyan in Fujian Province. Results BMD of middle-aged and old people decreased gradually with increasing age. BMD of females, especially postmenopausal women 50 years old or above, decreased more quickly than males .BMD of females above 50 years old were lower than that of males. Conclusions Prevention of OP should be stressed on women 50 years old or above. When BMD of lumbar spines do not accord with clinical symptoms, BMD of proximal femur should be referred to. Middle-aged and old people in Fujian Province should exercise properly every day,so as to maintain BMD, inhibit bone loss, and prevent OP.
