白马人与羌族围度特征的分析

Analysis of body circumference characteristics of Baima Tibetans and Qiang people

目的：研究白马人和羌族的围度特征。方法：采用人体测量法，在四川省平武县和阿坝羌族藏族自治州茂县随机测量233例白马人和602例羌族的13项围度值。结果：白马人男性头水平围、大腿围、小腿围、上臂围、前臂围和上臂最大围与年龄呈负相关，女性头水平围、颈围和腰围与年龄呈正相关，而大腿围和上臂最大围与年龄呈负相关；羌族男性胸围、吸气围、呼气围、腰围、腹围和臀围与年龄呈正相关，女性除头水平围和大腿围以外，其余围度指标均与年龄呈正相关。白马人男性小腿围、上臂围、前臂围、上臂最大围年龄组间差异具有统计学意义，女性所有围度在年龄组间的差异均具有统计学意义；羌族男性所有围度在年龄组间的差异均具有统计学意义，女性除头水平围外，其余围度指标在年龄组间差异均具有统计学意义。白马人和羌族围度指标中，围度值多表现为男性大于女性，而女性的臀围和大腿围均大于男性。结论：在13个中国族群中，白马人和羌族彼此围度特征最为接近，族源关系较近。

Objective： To study body circumference characteristics of Baima Tibetans and Qiang people. Methods： Thirteen circumference characteristics of 233 Baima Tibetan and 602 Qiang people in Pingwu city and the Tibetan Qiang Autonomous Prefecture of Aba in Sichuan province were measured by anthropometric method. Results： Circumferences of head, thigh, calf, biceps, fore-arm and maximum biceps of Baima males were negatively correlated with age. Female circumferences of head, neck and waist were positively correlated with age, but their circumferences of thigh and maximum biceps were negatively correlated with age. Qiang male circumferences of chest, inspiratory chest, expiratory chest, waist, abdomen and hip were positively correlated with age and female circumferences were positively correlated with age except circumferences of head and thigh. All the correlation coefficients were statistically significant. Among age groups, circumferences of calf, biceps, fore-arm and maximum biceps of Baima males had statistical significance and the differences of all the circumferences of females had statistical significance; the differences of all the circumferences of Qiang males were statistically significant. Except for the circumference of head, other indexes had statistical significance. Among Baima Tibetans and Qiang people, circumference indexes and the values of males were obviously larger than females. However, the circumference of hip and thigh of females was larger than males. Conclusion： In the 13 Chinese ethnic groups, the circumference characteristics of Baima Tibetans and Qiang people are close to each other and their ethnic relationship is closer.
