Objective We want to further understand the distribution characteristics of BMI, bone, fat and lean by analyzing these factors in groups of Uygur and Han, in order to improve the national health level, prevent disease and provide better medical treatment. Methods Using dual energy X-ray absorptiometry ( DMS LEXXOS) body component analysis software, analyze BMI and 3 measuring index ( Bone, Lean, Fat ) of Uygur and Han groups and make a multiple regression analysis. Results Uygur has a larger number of people who are overweight than Han nationality considering both gender and age, consistent with the previous reports. With the same BMI , the percentages of bone and lean of both male and female in Han nationality are greater than those of Uygur. But the percentage of fat of both male and female in Uygur is greater than that of Han nationality. There is little difference on the body construction between Uygur and Han groups, though the genetic theory elucidates some differences. After decades of interaction in culture, diet and other aspects, acquired factors have a great development space in remodeling our body. Conclusion Dietary structure imbalance and inadequate physical activity are the main reasons for overweight and increasing obesity rate, which also influence the physical health of Han and Uygur nationalities.%目的 通过对维吾尔族、汉族不同民族人群BMI、Bone、Fat及Lean的测定比较,了解新疆维、汉两族人群 Bone、Fat、Lean的分布特征,BMI的流行趋势以及有无明显的种族差异.探讨BMI与Bone、Fat及Lean之间的变化规律.方法 利用双能X线骨密度仪(DMS LEXXOS外星人)全身身体成分分析软件,对新疆维吾尔族、汉族人群的BMI以及3个测量指数(Bone、Lean、Fat)进行分析和多元回归分析.结果 无论男女或任何年龄段维吾尔族超重者均多于汉族人群;这与此前多篇相关报道一致[1-3].在同等BMI条件下,汉族男、女性Bone、Lean的百分比均大于维族男、女性.而维族男、女性Fat的百分比均大于汉族男、女性.维、汉人群的身体构建差异不大;从遗传理论的角度来说应该有一定的影响,但是经过近几十年各族人民在文化、饮食等方面的交流,后天因素有了很大的发展空间.结论 新疆维、汉族人群的膳食结构不平衡和身体活动不足是导致超重和肥胖率上升的最主要的原因,也是影响新疆汉族人群与维吾尔族人群身体健康的主要因素.
