中国城市汉族体质形态指标与经度的相关分析

Correlation analysis on human morphological index of Chinese urban Han with longitudes

为了研究中国汉族人群形态特征随经度的变化规律,2009年—2013年自西向东测量了中国31个城市汉族10 451例(男性5 048例,女性5 403例)成人的身高、体质量等16项指标值,并计算了身体质量指数,分析这些指标与经度的相关性.结果表明:随着经度值的增加,城市汉族男性和女性的身高、体质量总体上呈增加趋势.汉族男性和女性的身高均与经度呈正相关(P<0.05),在长度特征中只有躯干前高是造成这种相关性的体质特征.汉族男性的体质量与经度呈正相关,身高、躯干部围度和四肢骨骼发育水平是造成这种相关性的重要原因.汉族女性的体质量则与经度不呈相关性.

To learn the change rule of morphological characteristics of Chinese urban Han with longitudes, 10 451 urban adults （5 048 men and 5 403 women ）of 31 cities were investigated from the west to the east of China. Fifteen indexes, in- cluding stature and body weight, etc., were measured, and body mass index was calculated. The relationships of these in- dexes with longitudes were analyzed. The results showed that the statures and body weight increased generally with the in- crease of longitudes. The statures of male and female Han were positively correlated with longitudes（P 〈 0.05 ）, and height of suprasternal notch above sitting plane was the only length index resulting in this relationship. The body weight of male was positively correlated with longitudes, and the stature, the body circumference and the developmental level of limb bones were the important factors caused this relationship. The body weight of female had no relationship with longitudes.
