【摘 要】目的：分析新疆伊犁哈萨克自治州汉族、哈萨克族2个民族正常人群骨密度值测量结果及其差异性,确定本地区各民族骨密度正常值,为开展骨质疏松症防治工作提供判断骨密度的依据。方法：对年龄20～65岁来自新疆汉哈2个民族正常人群的731名个体进行腰椎骨密度测量,按10岁一个年龄段分别统计出均数和标准差,并且进行2个民族同性别、同年龄之间骨密度差异性的分析。设备为SIEMENS SOMATO ESPR IT+螺旋CT机,配合使用QCT骨密度测量系统,对所有调查对象的腰椎2～4椎体松质骨进行测量和计算。结果：男性腰椎骨密度峰值年龄在30一39岁、女腰椎骨密度峰值年龄在20一29岁，峰值后随年龄增加而骨密度下降，女性在50岁后特别在绝经以后出现明显下降，男性下降速度比较平稳。结论：新疆汉哈2个民族的骨密度正常值各年龄段均不相同,总体上是以哈族的骨密度值高于汉族。女性腰椎骨密度值在各年龄段均低于男性。上述结果为新疆伊犁地区诊断和治疗骨质疏松症提供了科学的诊断依据,也是进一步研究骨质疏松症的发病机理的可靠线索。

    【Abstract】Objective：To analyze the values of and compare the difference in bone mineral density (BMD) for peoples of Han and Kazak nationalities in Xinjiang, determine the normal BMD values of the two nationalities in this region, and provide the criteria for the diagnosis of osteoporosis. Methods：731 Han and Kazak individuals, aged 20-65, underwent quantiative computed tomography (QCT) densitom-etry of lumbar vertebrae with SIEMENS SOMATO ESPRIT+ spiral CT and calculation of BMD with QCT-3000 System. All BMD data were divided into different groups by age and nationality, then analyzed and compared by statistical method. Results：The ages of peak BMD for male Han and Kazak were 30-39and 20-29, respectively . ......
