摘要
目的：建立新疆地区维吾尔（维）、汉族两维骨密度测定的各年龄组的正常值范围，评价维、汉族骨密度和骨质疏松患病率之间的差异。方法：分别选取年龄２０～８０岁的２６７例维吾尔族和４０８例汉族，进行了两维骨密度的超远端测定。结果：（１）维、汉两民族两维骨密度呈现相似的变化规律，骨峰年龄男女均在３０～３９岁年龄段；（２）维、汉两维骨密度除２０岁年龄段有显著差异（Ｐ＜０．０５）外其余年龄段未见显著差异（Ｐ＞００５）；（３）维、汉男性５０岁以上（含５０岁）骨质疏松患病率分别为２００％和１８５％，经χ２检验无统计学差异，而维、汉绝经妇女骨质疏松患病率分别为２１６％和２２０％，两者之间也无统计学差异。结论：建立的维汉正常人群骨密度正常值及两维超远端骨密度测定对骨质疏松症的早期诊断都具有重要意义。
Objective: To obtain the reference ranges and to evaluate the difference of the bone density (BMD) between Uygur and Han nationalities in Xinjiang.Methods: The measurement of BMD at the juncture of radius and ulna was performed with single photon absorptiometry (SPA).In this study,there were 267 Uygurs and 408 Hans.The age ranged from 20 to 80 years old.Results: We got some significant results. First,the BMD of Uygur and Han nationality increased with their age. The BMD reached the highest point from 30 to 39 years old and then decreased. Secondly,there was no statistic difference in the BMD except the age ranged from 20 to 29 years old between Uygur and Han nationalities.Thirdly,there was no statistic difference in the prevalence rate of the osteoporosis between Uygur and Han nationalities including men and women.Conclusions: The reference ranges of the BMD of Uygur and Han nationalities were established and the measurement of twodimensional bone density at the juncture of radius and ulna is significant in the early diagnosis of osteoporosis.
