| 目的 检测绵阳地区不同民族的中老年人骨密度（bone mineral density，BMD)情况，了解BMD是否与民族因素有关。方法 用双能X线骨密度检测仪检测绵阳市城区、郊区和农村5039例50岁以上自愿者（其中男性1895例，女性3144例）腰 椎（L1-4)和左侧股骨颈和Ward’s三角BMD，对不同民族人的BMD进行比较。结果 本次检测人群包括汉族、藏族、羌族、回族，各年龄组男性和女性，各民族BMD分别比较，男性和女性比较的结果均显示，汉族BMD显著高于藏族、羌族、回族，回族高于羌族和藏族，羌族高于藏族（P<0.05)。结论 BMD与民族有关，产生民族差异可能与遗传、生活地区、饮食结构有关。造成BMD民族差异的这些因素还需进一步证实。 |

| Objective To evaluate bone mineral density (BMD) in middle-aged and older people living in the Mianyang region, and to study if there are ethnic differences in BMD. Methods Using dual-energy X-ray absorptiometry, BMD at lumbar spine, femoral neck and trochanter of 5039 individuals (living in urban, suburban and rural areas；1895 males and 3144 females) was assessed. BMD was compared among different ethnic groups. Results The study population included four ethnic groups - Han, Tibetan, Qiang and Hui. BMD was related to race. BMD in Han was significantly higher than that of Tibetan, Qiang and Hui (P < 0. 05). BMD in Hui was significantly higher than that of Tibetan and Qiang and BMD in Qiang was significantly higher than that of Tibetan (P <0. 05). Conclusion BMD was related to race，and the ethnic differences may be caused by genetic factors，living areas and dietary structure. Further studies are needed to confirm factors lead to the ethnic differences of BMD.
