摘要
目的了解华北、华东、华南地区人群皮肤颜色差异。方法利用MPA9色差测试仪测量华北（北京）、华南（深圳、东莞）、华东（常州、烟台）地区600名受试者额头、左脸颊、左手臂内侧、手背部皮肤颜色。采用国际照明学会规定的色度系统pa％。测量值得出每一受试者的个人类型角（ITAo），并根据Chardon等提出的肤色分类方法进行肤色分级。对各地区每个等级肤色的人次分布进行分析，对构成比进行r检验，在SPSS16．0软件上完成。结果在3个地区600名受试者2400个测试部位中，肤色I级占2．96％，Ⅱ级占39．88％，Ⅲ级占36．58％，1V级占16．96％，V级占3．63％，无Ⅵ级肤色。华北地区Ⅱ级肤色与I级肤色最多（530人次），Ⅳ、V级（37人次）最少；华东地区Ⅲ级肤色最多（335人次），IV、V级肤色居中（110人次）；华南地区I级肤色最少（2人次），IV级肤色最多（267人次）。左手背最黑，左脸颊、左手臂部位肤色最白。对所选部位不同肤色等级的构成比进行r检验后发现，部位之间肤色构成比差异有统计学意义（P〈0．01）。
Objective To assess the difference in human skin color among different geographical regions including Northern, Eastern and Sourthern China. Methods Six hundred individuals from Northern （Beijing）, Southern （Shenzhen and Dongguan in Guangdong province） and Eastern （Changzhou in Jiangsu province and Yantai in Shandong province） China were included in this study. A Muhi Probe Adapter MPA 9 device was used to measure the skin color of 4 body sites, including forehead, left cheek, left medial forearm, and the back of left hand, of these subjects. The Commission International de l＇Eclariage （CIE） L＊a＊b＊ values were recorded and individual typological angle （ITA） was calculated. Skin color was rated on a scale from 1 to 6 which was proposed by Chardon et al. The SPSS 16.0 software was used to process these data, and the skin color grade distribution was compared by chi-square test among different geographical regions and body sites. Results Among the 2400 tested sites from 600 subjects, 2.96% were rated as grade I, 39.88% as grade Ⅱ, 36.58% as grade Ⅲ, 16.96% as grade W, 3.63% as grade Ⅳ one as grade Ⅵ. In Northern China, I and llwere the most prevalent grade of skin color （530 sites）, while Ⅳ and Vwere relatively rare （37 sites）; in Eastern China, grade IU predominated （335 sites）, which was followed by Ⅳand V （110 sites）; in Southern China, the most common grade was Ⅳ （267 sites）, while the rarest grade was I （2 sites）. The back of the left hand seemed to be the blackest, while the left cheek and left medial forearm the whitest, with significant differences in the distribution of skin color grade between these 4 tested body sites （X2 = 106.00, P 〈 0.01）. Conclusions Skin color varies among different geographical regions in China, and among different sites on the human body.
