温州市区791例健康成人腰椎和髋部骨密度测量分析

Analysis of lumbar vertebrae and the hips bone mineral density in 791 cases of Wenzhou city healthy adults

目的：分析温州市区健康成人腰椎和髋部骨密度（BMD）的变化规律,建立本地区BMD正常参考值,为临床骨质疏松症（OP）的防治工作提供参考依据。方法：使用双能X线骨密度仪（DXA）,测量791例温州市区健康成人腰椎前后位（L1、L2、L3、L4、L1-4）和髋部BMD值,采用SPSS18.0软件进行统计学分析。结果：女性腰椎各部位和髋部BMD峰值在20~29岁,男性腰椎各部位和髋部BMD峰值在30~39岁,达峰后随着年龄增大BMD值开始降低,年龄越大BMD值越低。但男性在60岁后腰椎各部位BMD值有反弹现象。结论：温州市区健康成人腰椎和髋部BMD数据对本地区OP的诊断有一定的参考价值。

Objective： To analyze the change regularities of bone mineral density （BMD） in lumbar ver-tebrae and the hips of healthy adults in Wenzhou area, establishing of a local region of BMD normal reference value, in order to provide reference for prevention and clinical treatment of osteoporosis. Methods： Used by dual energy X-ray absorptionetry （DXA）, BMD of lumbar vertebrae （L1, L2, L3, L4, L1-4） and the hips in 791 cases of healthy adults in Wenzhou area was measured, statistical analysis was perfomed with SPSS 18.0 software. Results： The peak of BMD in lumbar vertebrae and the hips occurred at the age of 20-29 in females and 30-39 in males. After reaching the peak of BMD, the BMD value decreased with growing age, and it reduced with in- crease of age. However, the rebound phenomenon of BMD value in lumbar vertebrae occurred in men after 60 years old. Couelusion： BMD data of healthy adult men and women in Wenzhou area can provide certain refr- rence value for the diagnosis of osteoporosis in our region.
