目的  采集我国四川茂县羌族成人人体组成学数据，揭示羌族成人身体成分特点。方法  随机抽取羌族成人602名，采用生物电阻抗法对受试者进行体成分的测量，所得数据经SPSS 17.0 统计学软件处理。结果  羌族的各项指标性别间差异具有极显著统计学意义（P<0.01）。羌族成人脂肪相关指标与年龄相关性明显，体脂率、内脏脂肪等级随年龄的增长逐渐增大，肌肉量随年龄的增长先增大后减小。58.6%的男性和63.7%的女性处于超重或肥胖，31.8%的男性和43.6%的女性处于中心型肥胖，这可能会导致肥胖相关疾病发病率较高。结论  羌族成人的身体脂肪偏多，肌肉和骨骼较发达，这可能与茂县气温较低有关。

Objective  To collect body composition data of Qiang adults in Maoxian, Sichuan Province, in order to reveal the body composition characteristics of Qiang. Methods  A total of 602 adults of Qiang were randomly selected. The bioelectrical impedance method was used to measure the body composition of the subjects. The data were processed by SPSS 17.0. Results  There was a statistically significant difference between male and female Qiang adults in all index. The index related to fat in Qiang adults had a significant correlation with age. Percent body fat, percent trunk fat and visceral fat level increased gradually with age. The total body muscle mass increased first and then decreased with the increase of age. 58.6% of males and 63.7% of females were overweight or obese, 31.8% of men and 43.6% of women were at central obesity, which may lead to a higher prevalence of obesity-related diseases. Conclusion  The Qiang adults have more body fat and more developed muscles and bones, which may be related to the low temperature in Maoxian.
