摘要：

目的 探讨大连汉族正常人皮肤摩擦系数是否与性别和年龄有关。方法 414名汉族志愿者参加本项研究，年龄2个月至79岁，男187例，女227例；平均年龄（35.80 ± 1.33）岁。根据生长发育期将其分为3组：0 ~ 12岁为青春期前组；20 ~ 40岁为青壮年组；60 ~ 80岁为老年组。利用Courage-Khazaka多功能皮肤生理仪Frictiometer?誖 FR 770 and Corneometer?誖 CM 825探头分别测量不同部位皮肤摩擦系数和角质层的含水量（电容）。结果 在男性，除老年组前额部位皮肤摩擦系数明显低于手背部位外（P < 0.05），在其他各年龄组中，各部位之间皮肤摩擦系数差异无统计学意义；而在女性，除青壮年组前额部位的皮肤摩擦系数明显低于手背和眼外眦部位外（P < 0.001），在其他各年龄组中，各部位之间皮肤摩擦系数差异也无统计学意义。在男性，同一部位各年龄组之间皮肤摩擦系数差异无统计学意义；然而在女性的前额部位，老年的皮肤摩擦系数明显大于青春期前和青壮年（P值均 < 0.01）；在女性的眼外眦和手背部位，青壮年的皮肤摩擦系数明显大于青春期前和老年（P值均 < 0.01）。除青壮年女性手背和眼外眦部位的皮肤摩擦系数明显大于男性外（P分别 < 0.05和0.001），在其他各年龄组和各部位中，男女间皮肤摩擦系数差异无统计学意义。在青壮年男性，各部位皮肤摩擦系数与角质层的含水量呈正相关性（前额r = 0.6342，P < 0.0001；眼外眦r = 0.4501，P < 0.001；手背r = 0.3627，P < 0.01）；而在女性，仅老年前额和眼外眦的皮肤摩擦系数与角质层含水量呈正相关性（前额r = 0.2797，P < 0.05；眼外眦r = 0.486，P < 0.001）。结论 汉族正常人皮肤摩擦系数与性别、年龄、部位及角质层含水量有关。

Abstract:

Objective To determine whether skin friction coefficient （SFC） is associated with gender and age in a normal Chinese Han population. Methods A total of 414 Chinese Han subjects including 187 males and 227 females, who were aged from 0.15 to 79 years （mean age: 35.80 ± 1.33 years）, were enrolled in this study. According to human development stages, subjects were divided into pre-puberty group （aged 0 - 12 years）, young group （aged 20 - 40 years） and old group （aged 60 - 80 years）. SFC and stratum corneum capacitance were measured with A Frictiometer?誖FR 770 and Corneometer?誖CM 825 （C&K MPA 5）, respectively, on the dorsal hand, forehead, as well as canthus. Results SFC was higher on the dorsal hand than on the forehead in old males （P < 0.05）, and higher on the dorsal hand and canthus than on the forehead in young females （both P < 0.001）, while no significant difference was observed between the three measured sites in other groups of females or males （all P > 0.05）. In males, SFC on each measured site was similar among the three groups. In contrast, SFC was significantly higher on the forehead of females in aged than in young and pre-puberty groups （both P < 0.01）, and on the canthus and dorsal hand of females in young than in pre-puberty and aged groups （all P < 0.01）. The SFC on the canthus and dorsal hands of young females was higher than that of age-matched males （P < 0.0001 and 0.05, respectively）. A positive correlation was found between SFC and stratum corneum hydration in young males （foreahead: r = 0.6342, P < 0.0001; canthus: r = 0.4501, P < 0.001; dorsal hands: r = 0.3627, P < 0.01）. Moreover, SFC on the forehead （r = 0.2797, P < 0.05） and canthus （r = 0.486, P < 0.001） was also positively correlated with stratum corneum hydration in old females. Conclusion Skin friction coefficient varies with age, gender, body sites and stratum corneum hydration in normal Han populations.
