摘要：
Objective:To study the variation rules of head-facial somatoscopy indexes of northern China Han with age increase. Methods:From 2009 to 2012,17 head-facial observation indices of 9,582 northern Han (4,711 males and 4,871 females) were investigated.The gender differences and the changes with age were analyzed.Results:Along with the age,the northern Han mongoloid fold rate declined,eyeslists tended to become narrow and horizontal,nasal root became lower,zygomatic became more projected,eye color became brown and light,skin color turned dark,upper lip became higher,and lips became thinner.The comparison between sex showed that on the eyes,the mongoloid fold and eyefold of upper eyelid of females were higher than those of males.Females had more wide,outward and oblique eyeslits.On the nose,female nasal root was lower, the nasal profile more concave,the nasal base more upward,the nose lower,and nose width closer to interocular breadth.On the lips,the female upper lip height was lower,and thickness of lips was thinner.In addition,the female face was flatter with high triangular lobes, lighter hair color and skin color and deeper eye color.Conclusion:Head-facial morphological characteristic indexes of northern China Han change with age.%目的:研究中国北方汉族人头面部观察指标出现率随年龄增长而变化的规律.方法:2009年至2012年研究组调查了9582例(男性4711例,女性4871例)北方汉族的头面部17项观察指标,进行了性别间比较,分析了随年龄增长北方汉族头面部17项观察指标值的变化规律.结果:随年龄增长,北方汉族人出现蒙古褶率下降,眼裂变窄并趋于水平,鼻根变低,颧部更显突出,眼色变褐、变浅,肤色加深,上唇皮肤部变高,红唇变薄.性别间比较,眼部,女性的蒙古褶、上眼睑皱褶比男性发达,女性眼裂更宽,更向外、上倾斜;鼻部,女性的鼻根较低,鼻背更凹,鼻基部更上翘,鼻翼较低,鼻翼宽更接近眼内角间宽;唇部,女性上唇皮肤部较低,红唇较薄.此外,女性面部较扁平,耳垂三角形较高,发色、肤色较浅,眼色较深.结论:随年龄增长,北方汉族人头面部观察指标出现率出现明显的变化.
