摘　　要：目的了解中国北方地区农村居民皮肤纹理与日光暴露的关系。方法采用整群抽样方法抽取长期居住在辽宁省沈阳市王滨乡的当地居民361人作为调查对象,对收集到的手背部皮肤图像评定老化级别,使用Image-Pro Plus 5.0图像分析软件测量皮肤纹理间距、纹理形成的角度和网格数。结果沈阳农村居民日光高暴露和低暴露组皮肤老化级别平均值分别为(4.48±1.14)和(3.65±1.43)分,达到老化的人数分别为154和97人,老化比例分别为83.7%和54.8%;各年龄组日光高暴露组皮肤老化水平和老化比例均高于低暴露组,但差异均无统计学意义(P>0.05);年龄10～19和30～49岁及老化级别为4～6级时,日光高暴露组农村居民手部皮肤纹理的最大角度均大于低暴露组(P<0.05)。结论沈阳市农村居民皮肤纹理形成的角度与日光暴露密切相关。Objective To explore the effects of sun light exposure on skin texture in rural residents of north China.Methods Totally 361 subjects who lived most of their times in Wangbin town,Shenyang city,Liaoning province were recruited with cluster sampling.Skin aging grade of dorsal hand skin images of subjects was evaluated.Four skin texture parameters（distance,the number of angle,the max angle,and grids） were measured by using Image-Pro Plus software.Results The mean skin aging grade of high and low sun light exposure group was 4.48±1.14 and 3.65±1.43,with the number of residents with aged skin of 154 and 97,and the rate of skin aging of 83.7% and 54.8%,respectively.Skin aging grade and skin aging ratio of the subjects with high sun light exposure were higher than the subjects with lower exposure but without significant difference between the two groups（P0.05）.For the residents aged 10-19 years and 30-49 years or with the skin age grade of 4-6,the max angle was significantly higher in the subjects with higher sun light exposure than the subjects with lower exposure.Conclusion The angle formed by texture was significantly related to sun light exposure among rural residents in Shenyang municipality.
