目的  探讨造成内蒙古和新疆达斡尔族成人皮下脂肪发育差异的主要原因以及环境对皮下脂肪发育的影响。   方法  采用随机抽样方法调查了544例（新疆304，内蒙古240）达斡尔族成人9项身体围度值与6项皮褶厚度值，对新疆和内蒙古达斡尔族身体围度、皮褶厚度以及肥胖指标进行分析。   结果  新疆和内蒙古达斡尔族除大腿围外，其余8项身体围度、肱三头肌皮褶、肩胛下皮褶等2项皮褶厚度、皮-弗指数、体脂率、身体质量指数（BMI）等3项肥胖指数间差异有统计学意义。对应分析显示，与南方地区相比，北方地区皮下脂肪发育较强。   结论   内蒙古达斡尔族比新疆脂肪发育较强，肌肉发育较弱，两地超重及肥胖问题均较严重，建议加强锻炼注意饮食，低温、缺乏体育锻炼、经济和医疗水平低以及不健康的饮食习惯会导致皮下脂肪增厚。

Objective  To discuss the main reasons for the difference of sedum development between Daur adults in Inner Mongolia and Xinjiang.    Methods  Nine circumference values and six skin fold thickness of 544 adults of Daur nationality (304 in Xinjiang and 240 in Inner Mongolia) were investigated by random sampling. Circumferences, skin fold thickness and obesity indexes of Daur nationality in Xinjiang and Inner Mongolia were analyzed.    Results  There were significant differences in 8 circumference without thigh circumference, 2 skin fold thickness such as triceps skinfold, subscapularis skinfold, 3 obesity indexes such as Verv index, body fat rate, body mass index(BMI). Correspondence analysis showed that subcutaneous fat development was stronger in northern regions than in southern regions.    Conclusion  The Daur nationality in Inner Mongolia has more fat and less muscle than that in Xinjiang. The problems of overweight and obesity in both regions are serious. It is suggested to pay attention to exercise and diet. Low temperature，lack of physical exercise, low temperature, low economic and medical standards and unhealthy eating habits can thicken subcutaneous fat.
