BACKGROUND The positive association between physical activity and sunburn is a health behavior trade-off between the health benefits of physical activity and increased risk of skin cancer. PURPOSE We assessed walking, which is a common source of physical activity, and the prevalence of sunburn. METHODS This research used the 2015 National Health Interview Survey of adults (N = 26,632), age ≥ 18 years. We defined four exclusive categories of walking: (a) those who reported not walking; (b) only transportation (to get some place, such as work, a store, or public transit stop); (c) only leisure (such as for fun, relaxation, or exercise); and (d) both categories. We estimated the adjusted prevalence of sunburn by walking category and separately for walking duration; we stratified by gender and sun sensitivity. RESULTS The adjusted sunburn prevalence was not different between walking categories for women, but it was for men. Specifically, prevalence was lower for men who reported not walking, 34.1% (95% confidence interval [CI]: 32.2%-36.1%) compared to 38.8% (95% CI: 36.5%-41.2%) who walked for both purposes (p = .003). Walking duration was not associated with sunburn prevalence. CONCLUSION We could not determine whether sunburn occurred during walking trips because the questions were not asked as such. However, the results suggest that walking, unlike leisure-time physical activity (such as exercise, sports, or physically active hobbies), may not generally be associated with sunburn, except for the higher sunburn prevalence for men who walked for both leisure and transportation purposes.

步行和晒伤之间的横断面关联：癌症预防和风险因素之间的潜在权衡。


背景技术身体活动与晒伤之间的正相关性是身体活动的健康益处与皮肤癌风险增加之间的健康行为权衡。目的 我们评估了步行（这是身体活动的常见来源）以及晒伤的发生率。方法 本研究采用了 2015 年全国健康访谈调查，对象为年龄 ≥ 18 岁的成年人 (N = 26,632)。我们定义了四种独特的步行类别：(a) 报告不步行的人； (b) 仅交通（前往某个地点，例如工作地点、商店或公共交通站点）； (c) 仅限休闲（例如娱乐、放松或锻炼）； (d) 两个类别。我们按步行类别和步行持续时间分别估计了调整后的晒伤患病率；我们根据性别和阳光敏感性进行分层。结果调整后的晒伤发生率在女性中不同步行类别之间没有差异，但在男性中则不同。具体而言，报告不步行的男性患病率较低，为 34.1%（95% 置信区间 [CI]：32.2%-36.1%），而出于两种目的而步行的男性患病率为 38.8%（95% CI：36.5%-41.2%）。 p = .003)。步行时间与晒伤发生率无关。结论 我们无法确定步行旅行中是否发生晒伤，因为没有提出这样的问题。然而，结果表明，与休闲时的身体活动（例如锻炼、运动或体力活动爱好）不同，步行通常可能与晒伤无关，但休闲和交通步行的男性晒伤发生率较高。目的。
