本项目采用人体测量法,测量了976名（男性528人,女性448人）湖南土家族成人的身高、体质量以及肱三头肌、肩胛下、髂前上和小腿内侧皮褶的厚度,并根据公式计算体密度、体脂率、脂肪质量、脂肪质量指数、瘦体质量和瘦体质量指数。结果显示随年龄增长,小腿内侧皮褶厚度值逐渐减小,肱三头肌、肩胛下和髂前上棘皮褶以及体脂率、脂肪质量、瘦体质量、体质量指数、脂肪质量指数和瘦体质量指数值先增大后减小,体密度值先减小后增大;各年龄组中体密度、瘦体质量及其指数值女性明显低于男性,4项皮褶厚度值以及体脂率、脂肪质量及其指数值女性高于男性;与布朗族等24个族群比较,湖南土家族成人皮褶厚度处于中等水平,与门巴族、珞巴族、僜人、彝族等族群的亲缘关系较近。

The values of stature, body mass, triceps skinfold, subscapular skinfold, anterior superior iliac skinfold and medial calf skinfold of 976 Tujia adults (528 males and 448 females) were measured in Hunan by anthropometry method, and the values of the body dense, body fat rate, fat mass, lean body mass, fat mass index and lean mass index were calculated by formula. The results were as follows: 1) With the increase of age, the thickness of medial calf skinfold decreased gradually, the values of triceps skinfold, subscapular skinfold, anterior superior iliac skinfold, body fat rate, fat mass, lean body mass, body mass index, fat mass index and lean mass index increased and then decreased, while the value of body density decreased and then increased; 2) The values of body density, lean body mass and lean mass index of females were significantly lower than those of male in the same age group, while the values of four skinfold thicknesses, body fat rate, fat mass and fat mass index were significantly greater than those of male; 3) Compared with 24 ethnic groups such as Blang, the distribution of skinfold thickness of Tujia adults in Hunan is in the medium level, and Tujia is closely related to Monba, Lhoba, Deng and Yi ethnic groups.
