Background

Increases in outdoor temperature may lead to increases in sunburn, outdoor exposure, and skin cancer in human populations.

Objective

This study aimed to quantify sunburn incidence and risk for Ohio beachgoers exposed to varying outdoor conditions.

Methods

Sunburn incidence data were obtained through a prospective cohort study at East Fork Lake (Cincinnati, Ohio, USA). Recruitment occurred over 26 weekend days. Beach interviews and follow-up telephone interviews obtained exposure and health information. New sunburns were self-reported 8–9 days post-enrollment. Survey data were paired with ultraviolet radiation (UVR) index and temperature data for statistical analysis.

Results

Among 947 beachgoers, new sunburns were reported in 18% of swimmers. Sunburn incidence was associated with temperature (odds ratio = 1.2; 95% CI: 1.1 – 1.4) and UVR index (odds ratio = 1.6; 95% CI: 1.0 – 2.5) in models adjusted for water exposure, arrival time, and beach visit frequency. Some evidence of a temperature+UVR interaction was observed.

Limitations

Exposure and sunburn data were self-reported without clinical diagnosis and date of onset. The follow-up period enabled sunburns to be reported from a variety of days rather than only the beach visit day thereby limiting interpretation. Sun protection behaviors were not evaluated.

Conclusions

Temperature and UVR influence sunburn frequency. Temperature, however was more strongly associated with sunburn in beachgoers than the nearest measured UVR index, suggesting future investigations are needed to better understand how temperature effects sunburn development. Interventions for decreasing sunburn are needed.

评估美国内陆海滩上温度和紫外线辐射对晒伤发生率的影响：一项队列研究

背景

室外温度的升高可能导致人类晒伤，室外暴露和皮肤癌的增加。

客观的

这项研究旨在量化暴露于不同户外条件下的俄亥俄州泳客的晒伤发生率和风险。

方法

晒伤发生率数据是通过在东福克湖（美国俄亥俄州辛辛那提）进行的前瞻性队列研究获得的。招聘发生在26个周末期间。海滩访问和后续电话访问获得了接触和健康信息。入学后8–9天自我报告新的晒伤。将调查数据与紫外线辐射（UVR）指数和温度数据配对以进行统计分析。

结果

在947名泳客中，有18％的游泳者被晒伤。在针对暴露水，到达时间和沙滩游览进行了调整的模型中，晒伤的发生与温度（奇数比= 1.2； 95％CI：1.1 – 1.4）和UVR指数（奇数比= 1.6； 95％CI：1.0 – 2.5）相关。频率。观察到温度+ UVR相互作用的一些证据。

局限性

自我报告的暴露和晒伤数据没有临床诊断和发病日期。随访期使人们可以在不同的日子报告晒伤，而不仅仅是在海滩拜访的日子，因此限制了解释。没有评估防晒行为。

结论

温度和紫外线辐射会影响晒斑频率。但是，比起最近测得的UVR指数，温度与泳客晒伤的相关性更强，这表明需要进一步研究以更好地了解温度如何影响晒伤的发展。需要减少晒伤的干预措施。
