白马人皮褶厚度的调查研究

Research on skinfold thicknesses of Baima

为了探究白马人的脂肪发育特点及族群关系,以四川省平武县233例成年白马人为研究对象,运用人体测量方法调查白马人的7项皮褶(面颊、肱二头肌、肱三头肌、肩胛下、髂嵴上、髂前上棘、小腿内侧)厚度和体脂率,并与我国西南地区的15个族群进行比较.结果表明:白马人男性躯干部分皮褶较厚(其中髂嵴上皮褶厚度最大),四肢皮褶厚度较小(其中肱二头肌的皮褶厚度最小);女性除了肱三头肌皮褶较厚以外,其余部位的皮褶厚度情况与男性相同.同年龄组女性的7项皮褶厚度均大于男性.体脂率结果显示,白马人男性不属于肥胖,白马人女性45岁以上的属于肥胖.基于皮褶厚度的聚类分析结果表明,白马人与四川羌族的亲缘关系最近,与四川汉族、贵州屯堡人和甘肃汉族较为接近.

To analyze the fat development characteristics and ethnic relations of Baima, anthropometric methods were adopted to measure the skinfold thickness of face, biceps, triceps, subscapular, suprailiac, anterior superior iliac spine, calf and percentage of body fat（ PBF ） of 233 Baima adults from Pingwu County of Siehuan Province. Furthermore, the skinfold of Baima was compared with 15 ethnic groups in southwest of China. The results showed that as for Baima males, the skinfold of trunk were rather thicker, among which suprailiac skinfold was the thickest, and the skinfold of limbs were thinner, among which the skinfold of biceps was the thinnest. As for Baima females, the feature of skinfold thickness was similar as that of males with the exception of triceps, which was thicker. The thickness of seven skinfold of females was larger than that of males. The result of PBF showed that the males of Baima were not fat, while the females above 45 years old belonged to the fat groups. The cluster analysis according to skinfold thickness showed that Baima is the closest with Qiang, and close with Tunpu and Han in Sichuan as well as in Gansu.
