江西汉族人头面部形态特征的年龄变化

Variation of Morphological Traits in the Head and Face of the Han in Jiangxi

为研究人类头面部形态特征随年龄增长而变化的规律,赴江西省丰城调查了汉族705例(城男151,城女156,乡男203,乡女195)38项头面部指标,并计算了12项头面部体质指数,对江西汉族头面部形态特征的年龄变化进行了初步分析。结果显示:江西汉族人头面部形态特征随年龄增长呈现一定的变化规律。1)随年龄增长,江西汉族成人有蒙古褶率下降,眼裂倾斜度渐趋水平,眼色变浅,上唇皮肤部高度狭窄型率下降,红唇厚度窄型率上升。2)相关分析显示,江西汉族鼻宽、口裂宽、鼻深、上唇皮肤部高度、容貌耳长、容貌耳宽与年龄呈正相关;眼外角间宽、唇高、红唇厚度与年龄呈负相关;3)江西汉族人头长宽指数、口指数与年龄呈负相关。4)方差分析显示,上述指标值、指数值在不同年龄组间差异均具有统计学意义。

This study examined the changing features of head-face morphology with the increaseing age in a large sample of humans. Thirty-eight head-face characteristics on 705 individuals （151 urban males, 156 urban females, 203 rural males, and 195 rural males） of Han were investigated from Fengcheng, Jiangxi Province in May 2010. Twelve physical indices were calculated. Preliminary analysis was carried out on these head-face characteristics with the following results. 1） With increasing age, the Mongoloid fold rate decreased, the direction of eyeslit inclination moved towards a middle range, eye color became shallow the height of the narrow part of the upper lip declined, and lip thickness increased. 2） Correlation analysis showed that nose breadth, mouth breadth, nasal depth, upper lip height, physiognomic ear length, and physiognomic ear breadth were positively correlated with age. In contrast, external biocular breadth, lip height, and thickness of the lips were negatively correlated. The length- breadth index of the head and the lip index were also negatively correlated with age. Analysis of variance showed that there were significant differences between the different age groups in the variable and index values used in this research.
