中国木雅人、尔苏人、八甲人与空格人的皮褶厚度

Skinfold thickness of Muya,Ersu,Bajia and Kongge adults in China

在云南省西双版纳与四川省石棉县调查了157例木雅人、120例尔苏人、158例八甲人与71例空格人的皮褶厚度,包括面颊皮褶、肱二头肌皮褶、肱三头肌皮褶、肩胛下皮褶、髂前上棘皮褶、髂嵴上皮褶、小腿内侧皮褶共7项.比较研究了4个族群与我国西南地区15个族群的皮褶厚度并进行聚类分析.结果表明:①木雅人、尔苏人、八甲人与空格人男性的7项皮褶厚度均显著低于女性数值;②木雅人与尔苏人的各项皮褶厚度值较接近,二者的面部皮下脂肪堆积水平较高,八甲人身体躯干和四肢皮下脂肪堆积水平优于其他3个族群,空格人的各项皮褶厚度均较小,皮下脂肪堆积水平较低;③同西南地区其他15个族群的皮褶厚度相比,八甲人的数值偏大,尔苏人和木雅人的数值属于偏大或中等偏大,空格人的数值较小;④聚类分析结果显示,木雅人与尔苏人接近,八甲人与四川汉族族群接近,而空格人与云南傣族和云南蒙古族接近.

The skinfold thicknesses of facial,biceps,triceps,subscapular,supraspinale,suprailiac and calf were investigated in 157 Muya adults,120 Ersu adults,158 Bajia adults and 71 Kongge adults living in Xishuangbanna of Yunnan Province and Shimian of Sichuan Province. The skinfold thickness of four ethnic groups and 15 ethnic groups in southwest-ern China was compared,and cluster analysis was carried out. The results show:① The seven skinfold thickness of Muya,Ersu,Bajia and Kongge are lower in males than that in females. ②The skinfold thickness of Muya and Ersu is relatively close.The facial subcutaneous fat accumulation level of Ersu and Muya are higher. The level of subcutaneous fat accumulation in the torso and limbs of Bajia is the best among the four ethnic groups. The skinfold thickness of Kongge is small and the level of subcutaneous fat accumulation is low. ③Compared with the skinfold thickness of the other 15 ethnic groups in the south-western region,the values of Bajia are large,and the values of Ersu and Muya are large or mediumlarge,and the values of Kongge are small. ④ The results of cluster analysis showed that Muya is close to Ersu,Bajia is close to the Han ethnic groups in Sichuan,and Kongge is close to the Dai and Yunnan Mongol.
