摘　　要：目的通过测量乌鲁木齐市1837人次汉族、维吾尔族健康人群的骨密度（Bone Mineral DensityBMD）．确定本地区汉族、维吾尔族DXA测量骨密度的正常参考值范围，建立本地区汉族、维吾尔族DXA测量骨密度的正常数据库，并比较、探讨汉族、维吾尔族BMD随年龄变化的规律。方法使用法国DMS公司生产的Lexxos型双能x线骨密度仪（Duelenergy X-ray absorptiometer，DEXA）对乌鲁木齐地区20，75岁以上的汉族、维吾尔族健康人群的腰椎前后位、左侧股骨近端进行BMD测定。按不同性别每5岁分为一年龄组，得出骨密度均值、标准差，并进行两组样本均数的f检验。结果汉族、维吾尔族男性及女性各部位出现骨峰值的年龄段略有不同，但多数均在40岁前随骨量逐渐增加而达到骨峰值。其后随年龄的增长BMD降低，女性BMD在50岁后加速下降，男性无加速下降的趋势。结论本研究建立了乌鲁木齐市汉族、维吾尔族DXA测量常规检查部位各年龄段BMD的正常值及骨质疏松诊断参考值，为今后骨质疏松的预防、诊断、研究提供了客观数据，也为国内的资料比较提供了依据。Objective To determine bone mineral density （BMD） of Han and Uygur nationality of 1837 people in health in Urumqi and further to investigate the change regularities of BMD with age. Methods BMD values of lumber spine and proximal femur in healthy subjects were determined by duel energy X-ray BMD detector （Model lexxos made by DMS Co. Ltd, France） in Urumqi residents aged over 20 - 75. The mean BMD value, standard deviation （SD） and according to different sex and age which per 5 years be in one group. Result The peak bone mass for each skeleton site appeared in different ages in both Han and Uygur nationality. The females BMD showed a sharp decline after 50 years while no such a tendency occurred in males post the peak. Conclusions This study may provide useful evidence and data for osteoporosis study in the Han and Uygur ethnic group in Urmuqi area.
