布依族成人围度特征的研究

Study on circumference character of adults of Bouyei

对贵州省黔南州494例(男259例,女235例)布依族成人的围度值进行测量,分析了不同年龄组围度值的变化情况,并与我国其他15个族群的围度值进行聚类分析与主成分分析.结果显示:(1)不同年龄组的头水平围值变化很小;(2)男性与女性四肢围度的最大值均在30-岁组,男性躯干围度的最大值在40-岁组,女性胸围、臀围最大值在30-岁组,腹围最大值在50-岁组;(3)躯干围度年龄组间的绝对变化值高于四肢围度,但相对变化率都低于四肢围度;(4)同年龄组间比较,女性的腹围、臀围、大腿围值多大于男性,而四肢围度值小于男性;(5)我国16个族群进行比较,布依族围度值较小,但在5个南方族群中,布依族围度值较大;(6)聚类分析显示,我国16个族群围度可分为2个大组,即南北方混合组与北方组,布依族男性和女性均属于南北方混合组;(7)主成分分析显示,南北方混合组上肢围度值小,北方组上肢围度值大,上肢围度值是16个族群分组的主要依据.

Based on the measurement of the circumferences of 494 adults （295 male, 235 female） of Bouyei nationality from Qian-nan Zhou, Guizhou Province, the changes of circumference value with age were studied. Meanwhile, the cluster analysis and principal component analysis of the circumference values of Bouyei adults with other 15 nationalities were performed. The results were as follows： （1） The horizontal head circumference of Bouyei adults changed little with age. （2） The maximum limb circumference of male and female occurred in 30-age group, and the maximum trunk circumference of male occurred in 40-age group. While the maximum chest and hip circumference of female occurred in 30-age group, and maximum abdominal circumference occurred in above 50-age group. （3） The absolute change value of trunk circumference was higher than that of limb circumference, but relative change rate was lower than that of limb circumference. （4） In comparison among the same age groups, abdominal, hip and thigh circumference values of female were higher than those of male, while the limb circumference values were lower than those of male. （5） Among the 16 nationalities of China, circumference values of Bouyei were relatively smaller, but among the 5 southern nationalities, the circumference values of Bouyei nationality were relatively bigger. （6） Cluster analysis showed that, according to circumference values, the 16 nationalities can be divided into two groups： south-north mixed group and north group. And Bouyei belonged to south-north group. （7） Principal component analysis showed that the upper limb circumference of south-north mixed group was smaller while that of north group was bigger. Upper limb circumference was the main standard for the grouping of the 16 nationalities.
