四川邛崃汉族头面部形态特征的年龄变化

Variation of Morphological Traits in Head-facial Values of Han in Qionglai of Sichuan Province

【目的】研究随年龄增长,成人头面部指标、指数值的变化规律。【方法】在四川邛崃市城市和乡村调查了汉族748例(男为368例,女为380例)成人的38项头面部体质指标,计算了13项头面部体质指数,统计了指数分型情况,对邛崃汉族头面部形态特征的年龄变化进行了初步分析。【结果】①头宽、眼内角间宽、眼外角间宽、形态面高、唇高、红唇厚度、头水平围这7项指标与年龄呈负相关。②鼻宽、口裂宽、上唇皮肤部高度、容貌耳长、容貌耳宽、面颊皮褶这6项指标与年龄呈正相关。③随年龄增长,有内眦褶率、眼外角高率下降,颧部愈显突出。眼色褐色率上升而黑褐色率下降,红唇薄型率明显增加而中等型率、厚型率下降,鼻翼中等率呈下降趋势而宽阔率呈上升趋势。④头长宽指数、头长高指数、口指数均数随年龄增长而下降,头面宽指数、鼻指数则随年龄增长而上升。【结论】头面部一些测量指标值、指数值以及观察指标分型比例随年龄增长呈现有规律的变化。

Abs [Objective] To investigate the variations of craniofacial characteristic with the increase of the age. [Methods] The craniofaeial characteristics on 748 adults （368 males, 380 females） of Han people reside in Sichuan were investigated. Thirty-eight items of the craniofacial physical indices and other 13 items of craniofacial physical data were calculated. These eraniofacial characteristics change have been analyzed with the growth of the age. [ Results ] （ 1 ） The indices of head breadth, interocular breadth, external biocular breadth, morphological facial height, lip height, thickness of lips and horizontal head circumference have negatively correlation with the increase of the age. （2） The indices of nasal breadth, mouth breadth, upper lip skin height, physiognonic ear length, physiognmic ear breadth and facia skinfold have positive correlation with the increas of the age. （3） With the growth of the age, some of the characteristics have significant change. The occurrence rate of Mongoloid fold and external biocular height declines. Zygomatic process protrude more than before. What＇s more, the occurrence rate of the brown color of eye has increased, but that of black brown ones has decreased ; the rate of thin lips out of the Thickness of lips has increased too, but the rate of middle-thick lips types has decreased; and the wide types of alae nasi breadth has increased, but the middling ones has decreased. （4）With the growth of the age, the cephalic index such as length-breadth index, length-height index and stomatic index have declined. Moreover, transverse cephalo-facial index and Height-breadth index ascended. [Conclusion] With the growth of the age, the measured value and index of eraniofacial characteristic along with the typing of the observed value change with regularity.
