革家成年人头面部形态特征的年龄变化

目的 探讨革家人头面部形态特征随年龄增长而变化的规律。方法 按照国际学术界规定方法，在贵州黄平县共调查了311例（男性为159例，女性为152例）革家成年人38项头面部指标，并计算了12项头面部体质指数，对革家人头面部形态特征的年龄变化进行了初步分析。结果 随年龄增长，革家人有蒙古褶率下降，眼色变浅，上唇皮肤部变高，红唇变薄。革家人形态面高、上唇皮肤部高度、容貌耳长、容貌耳宽与年龄呈正相关，革家人头宽、眼外角间宽、唇高、红唇厚度与年龄呈负相关，革家人额最小宽、下颌角间宽、眼内角间宽、口裂宽、鼻深与年龄无相关。革家人容貌面、形态面、头面宽、头面高指数与年龄呈正相关，头长宽、头长高、口指数与年龄呈负相关。 结论 革家人头面部形态特征随年龄增长呈现一定的变化规律。

Age variation of morphological traits in the head and face of Gejia people

Objective To study the change law of head-face morphological characters with the increasing age. Method Thirty-eight physical indices of head and face of 311 Gejia adults (159 males, 152 females) were investigated in Huangping county of Guizhou province. Twelve physical indices of head and face were calculated. Preliminary analysis was carried out on the age change of head-face morphological characteristics. Results With increasing age, the Mongoloid fold rate decreased, eye color became shallow, the height of the narrow part of the upper lip raised, and lip thickness decreased. Correlation analysis showed that morphological facial height, upper lip height, physiognomic ear length, and physiognomic ear breadth were positively correlated with age. In contrast, head breadth, external biocular breadth, lip height, and thickness of the lips were negatively correlated. The minimum frontal breadth, bigonial diameter, interocular breadth, mouth breadth, nasal depth showed no correlation with age variation. With increasing age, physiognomic facial height, morphological facial height, transverse cephalo-facial index, and vertical cephalo-facial index were ascending. Moreover, cephalic index, length-height index of head and lip index were declining. Conclusion With the growth,the head and face measurements, index of craniofacial characteristic and the proportion of observed indices change with regularity.
