Little is known about the association between types of skin and subcutaneous diseases and UV protection literacy.
To assess the burden and treatment of skin diseases in Ninger County, Yunnan Province, and establish a transtheoretical model for optimizing public perceptions and behaviors regarding UV radiation.
Electronic medical records of outpatients from the dermatology department were collected from January 2022 to July 2024, and a self-administered questionnaire assessed the public knowledge about UV exposure risks and behaviors. Multivariable regression models were used to investigate the correlation between UV protection literacy and dermatological situations. Knowledge, Attitude, and Practice (KAP) model was established and re-examined by Structural Equation Modeling (SEM).
Significant seasonal trends in skin disease incidence were observed. Each unit increase in UV protection knowledge score was associated with a 59.1% lower risk of pigmented skin disease and a 56.1% lower risk of skin tumors. A KAP model was developed with coefficients of 0.264 ( < 0.001), 0.603 ( = 0.041), 0.605 ( < 0.001). The impact of redundant residuals on the evaluation of the model fit cannot be ignored in SEM.
The negative association between UV protection literacy and certain skin disease occurence revealed the essentiality of UV protection dissemination.
关于皮肤和皮下疾病类型与紫外线防护知识之间的关联，人们了解甚少。
评估云南省宁洱县皮肤病的负担和治疗情况，并建立一个跨理论模型，以优化公众对紫外线辐射的认知和行为。
收集2022年1月至2024年7月皮肤科门诊患者的电子病历，并通过自填式问卷评估公众对紫外线暴露风险和行为的了解。使用多变量回归模型研究紫外线防护知识与皮肤病状况之间的相关性。通过结构方程模型（SEM）建立并重新检验知识、态度和实践（KAP）模型。
观察到皮肤病发病率存在显著的季节性趋势。紫外线防护知识得分每增加一个单位，色素沉着性皮肤病风险降低59.1%，皮肤肿瘤风险降低56.1%。建立了一个KAP模型，系数分别为0.264（<0.001）、0.603（=0.041）、0.605（<0.001）。在结构方程模型中，冗余残差对模型拟合评估的影响不可忽视。
紫外线防护知识与某些皮肤病发生之间的负相关关系揭示了传播紫外线防护知识的必要性。
