中国尔苏人、木雅人、空格人与八甲人的成人围度特征

Circumference characteristics of adults of Ersu,Muya,Kongge and Bajia in China

为了解中国西南地区4个未识别族群(尔苏人、木雅人、八甲人和空格人)的体质状况和亲缘关系,对四川省的尔苏人120例和木雅人157例、云南省的空格人71例和八甲人158例进行身体围度特征的调查,包括头围、颈围、胸围、吸气胸围、呼气胸围、腰围、腹围、臀围、大腿围、小腿围、上臂围、前臂围、上臂最大围13项指标.选取中国南方的11个族群与之进行围度特征的比较.结果表明:4个族群中,男性躯干部的3项围度按大小排列顺序均为胸围>臀围>腹围;女性排列顺序则为臀围>腹围>胸围.男性的上肢围度(上臂围、前臂围、上臂最大围)普遍大于女性,女性的臀围和大腿围普遍大于男性.基于围度的聚类分析结果表明,尔苏人、木雅人、八甲人的亲缘关系较为接近,并且与云南傣族的亲缘关系接近;空格人则与贵州革家人的亲缘关系较为接近.

To learn the physical constitution status and genetic relationships of four unidentified populations living in thesouthwest area of China, i.e. Muya, Ersu, Kongge, Bajia, the 13 circumference values of 120 Ersu adults and 157 Muyaadults living in Sichuan Province, 71 Kongge adults and 158 Bajia adults living in Yunnan Province were investigated. Thethirteen indexes included head circumference, neck circumference, chest circumference, chest circumference at inspiration,chest circumference at expiration, waist circumference, abdomen circumference, hip circumference, thigh circumference,calf circumference, girth of upper arm, girth of fore-arm and maximum biceps circumference. Eleven populations in thesouth China were chosen to be compared with the four unidentified populations on the circumference characteristics. Theresults showed that as for the body circumference of the four populations, the sequence of male was chest circumference 〉hip circumference〉abdomen circumference; while the sequence of female was hip circumference 〉 abdomen circumference 〉chest circumference. The upper limb circumferences including girth of upper arm, girth of fore-arm and maximum bicepscircumference of male were generally higher than those of female, and the hip circumference and thigh circumference offemale were generally higher than those of male. According to the cluster analysis based on the circumference, the relation-ships of Ersu, Muya and Bajia were close, and the three populations were close to Dai of Yunnan Province. While Konggewas close to Gejia of Guizhou Province.
