| 目的 了解新疆维吾尔族、汉族老年男性人群腰椎、髋关节T值的差异和特点，为临床合理选择骨密度检测提供科学依据。方法 收集2011年10月至2013年8月入住我院干部病房的维、汉老年男性高血压或（和）糖尿病患者320例，根据民族、年龄段分为12组；使用法国DMS生产的双能X线骨密度仪(Duel energy X-ray absorptiometry，DEXA)测量腰椎、髋关节骨密度（Bone mineral density，BMD)T值，统计各组腰椎、髋关节T值平均值，采用t检验及卡方检验对数据进行分析整理。结果 (1)维吾尔族老年男性腰椎、髋关节T值均比汉族老年男性低，差异有统计学意义（P <0. 05)；随年龄增加，维、汉两族老年男性腰椎、髋关节T值均呈下降趋势。（2)相同民族同年龄段组间比较，腰椎T值均高于髋关节。维吾尔族老年男性患者在60~64岁、65 ~69岁、70 ~74岁、75 ~79岁、>85岁5个年龄段，腰椎T值与髋关节T值比较差异有统计学意义（P < 0. 05)，80~84岁年龄段两者比较差异无统计学意义；汉族老年男性患者在60 ~64岁、70 ~74岁、75~79岁、80 ~84岁、>85岁5个年龄段，腰椎T值与髋关节T值比较差异有统计学意义(P <0.05)，65~69岁年龄段两者比较差异无统计学意义。结论 骨密度T值受民族因素的影响；相同民族间腰椎与髋关节T值也存在差异。本研究为新疆地区不同民族、不同年龄段老年男性人群合理选择优势部位骨密度检测提供了一定的临床指导意义。 |

| Objective To investigate the difference and characteristics of the T-score of bone mineral density (BMD) of the lumbar vertebrae and the hip between elderly Uyghur and Han males，and to provide the scientific basis for BMD detection. Methods A total of 320 elderly male Uyghur and Han patients，who were hospitalized in cadre wards in the First Affiliated Hospital of Xinjiang Medical University and diagnosed as hypertension or diabetes from October 2011 to August 2013，were selected. All the patients were divided into 12 groups according to ethnicity and gender. BMD of the lumbar vertebrae and the hip was detected using Lexos dual energy X-ray absorptiometry (DEXA，DMS Co. Ltd，France). The average T-scores in each group were calculated and the differences were analyzed using t-test and Chi-square test. Results The T-score of the lumbar vertebrae and the hip in the elderly Uygur males was significantly lower than that in Han males (P < 0. 05). Along with the increase of age，the T-scores of the lumbar vertebrae and the hip in both Uyghur and Han males decreased. When compared within same ethnicity and same age，the T-score of the lumbar vertebrae was higher than that of the hip. And significant difference was observed in every elderly male Uyghur age group (P < 0. 05) except in 80?84 year old group. Meanwhile，no difference was observed in the 65?69 year old group in the Han patients. Conclusion Ethnic factor has an important role in BMD. Even for people with the same ethnicity，there are significant differences between T-scores of the lumbar vertebrae and the hip. Our research provides some clinical significance for different nationality and different age groups in elderly male people and directes them how to choose the dominant position to detect the BMD. |
