广东粤西地区正常人双能X线骨密度的检测分析

为了解中国粤西地区正常人骨密度水平，提高沿海地区骨质疏松症的防治水平。本文采用法国ＳＯＰＨＯＳＬ－ＸＲＡ骨密度仪，对３０１例正常人的前臂、髋骨及腰椎进行测量分析。结果：男、女性前臂和腰椎峰值骨量均为３０～３９岁，股骨颈、Ｗａｒｄ’ｓ区峰值骨量男、女性均为２０～２９岁。男、女性腰椎和髋骨的骨密度累积下降率均在５０岁后加快，尤以女性为明显。男女组的前臂骨密度测定值均低于文献报道。通过本组正常人骨密度的检测，为本地区骨质疏松病的研究提供了有益的参考数据。

Determination of dual energy X-ray bone mineral density in normal Peoples in western region of Guangdong

To evaluate bone mineral density of normal humans in westesn region of Guangdong,and improve level of prevention and care of osteoporosis in south coastland of China, BMD of forearm,femoral neck,lumbar vertebrae of 301 healthy subjects was measured by SOPHOS L-XRA instrument made in France. Results showed that the peak mass of BMD of forearm and lumbar vertebrae occurred in age group 30-39 of both males and females. The peak values of femoral neck,Ward's triangle occurred in age group 20-29 of both sexes. The rate of accumulative loss of BMD of lumbar vertebrae and hip bone in people over 50 years old was rapid for both sexes,especially for females. The values of BMD of forearm in both sexes were lower than those reported in literatare. By BMD measuring the normal people,we put forward useful reference data for research of osteoorosis in that region.
