南疆地区维吾尔族面部微笑美学的动态特征研究

摘要

Objective To study the gender aesthetical characteristics of lips during smile and the changes with aging of Uygur people in southern Xinjiang Uygur(Uygur). Methods Total 273 Uygur volunteers from the southern Xinjiang were selected randomly, including 137 males and 136 females. They are divided into three groups according to their ages(14-19 years old,24-34 years old and 39-50 years old),i. e. ,Group 1(47 males and 48 females),Group 2(45 males and 43 females)and Group 3(45 males and 45 females). After videos of these subjectsˊface were recorded,their images in both standard rest position and smile position were selected in order to measure the length and vermilion thickness of upper lip,and width and height of angulus oris. And then,variance analysis was made among the three groups. Results The lengths of upper lips in smile position of the males were greater than those of the females in group 2 and 3(P < 0. 05);the dynamic changes in the four indexes of the males decreased with the increase of ages,and the differences were significant between group 3 and group 1;the dynamic changes in the length of upper lip and in the width of angulus oris of the males were smaller significantly than those of the females in group 2 and 3(P < 0. 05),and the dynamic changes in the height of angulus oris of the males in group 3 were smaller significantly than those of the females in the same group(P < 0. 05). Conclusion The lip shape of southern Xinjiang Uygur males and females will change with the increase of age;the dynamic changes in smile of Uygur males are smaller than those of Uygur females who are more easily affected by aging.%目的：评估南疆地区维吾尔族（简称维族）口唇部微笑特征的性别特征和增龄性变化。方法随机选取南疆地区维族志愿者273名，其中男性137名，女性136名。根据年龄段（14~19岁，24~34岁，39~50岁）分为3组：组1（男性47人，女性48人），组2（男性45人，女性43人）和组3（男性45人，女性45人）。为受试者录制微笑视频后，选取标准息止位和微笑位图像，分别测量息止位和微笑位的上唇长度、上唇唇红厚度、口角宽度和口角高度，进行组间方差分析。结果微笑位男性上唇长度在组2和组3均大于女性（P <0.05）；男性4项指标的动态变化幅度均随年龄增长而降低，组3与组1相比差异显著；男性上唇长度、口角宽度的动态改变在组2和组3明显小于女性（P <0.05），口角高度的动态改变在组3明显小于女性（P <0.05）。结论南疆地区维族男性和女性口唇部形态均存在规律性的！龄性变化；维族男性微笑的动态变化小于女性，且更易受到老龄化的影响。
