三亚与沈阳农村地区人群手背部皮肤纹理老化配对比较研究

A paired comparison study of dorsal hand skin texture aging in rural population of Shenyang and Sanya

目的:比较三亚与沈阳两地农民手背部皮肤纹理老化程度,探索紫外线对皮肤老化的影响。方法:采用I mage-Pr o Pl us图像分析软件,测量三亚与沈阳两地人群手背部皮肤纹理间距、纹理形成的角度和网格数。结果:除中年男性外,男女各年龄组的三亚地区人群皮肤纹理最大角度均显著高于沈阳地区人群,两地男性皮肤纹理最大角度达到老化的OR值为6.5(95%CI=1.5-28.8),女性的OR值为11.5(95%CI=2.7-48.8)。三亚地区青中年女性皮肤纹理间距显著高于沈阳地区女性,网格数显著低于沈阳地区女性。男性的皮肤网格数仅在青年时期表现出显著的两地差异。结论:三亚农村地区人群的手背部皮肤纹理老化程度高于沈阳农村地区人群,其中皮肤纹理最大角度能够更有效地反映两地人群皮肤老化的差异。

Objective To compare the skin texture aging level of subjects lived in Sanya and Shenyang and explore the effects of sun exposure on the skin aging. Methods Image-Pro Plus software was utilized to measure the distance between texture, the max angle and grids. Results Except for the middle-aged men, the max angle of Sanya subjects was higher than that of Shenyang subjects in each gender and each age group. Compared with the males lived in Shenyang, the risk of reaching the old of the max angle was 6.5 （95%C1=1.5-28.8） for the males lived in Sanya. For females this risk was 11.5 （95%CI =2.7-48.8）. Compared with their Shenyang counterparts, the young women and middle-aged women lived in Sanya had a significantly higher distance and fewer grids. The difference of grid between the men lived in Sanya and Shenyang was significant only in young age. Conclusion The dorsal hand skin texture aging of Sanya rural population was older than that of Shenyang rural population. The max angle can distinguish the difference between Sanya and Shenyang subjects more effectively.
