There is limited literature about adults in the United States who usually or always spend time outdoors for the purpose of developing a tan, defined as intentional outdoor tanning. Using data from the 2015 Summer ConsumerStyles, an online cross-sectional survey weighted to the US adult population (n=4,127), we performed unadjusted and adjusted multivariable logistic regressions to examine the associations between demographic characteristics, behaviors, and belief factors related to skin cancer risk and intentional outdoor tanning. Nearly 10% of the study population intentionally tanned outdoors. Outdoor tanning was more prevalent among women (11.4%), non-Hispanic white individuals (11.5%), those aged 18-29years (14.1%), those without a high school diploma (12.7%), and those in the northeast United States (13.2%). The adjusted odds of outdoor tanning were significantly higher among women than men (adjusted odds ratio [AOR] 1.51, 95% confidence interval [CI] 1.12-2.04); those with a history of indoor tanning or recent sunburn than those without (AOR 2.61, CI 1.94-3.51; AOR 1.96, CI 1.46-2.63, respectively); those who agreed they looked better with a tan than those who did not (AOR 6.69, CI 3.62-12.35); and those who did not try to protect their skin from the sun when outdoors than those who did (AOR 2.17, CI 1.56-3.04). Adults who engaged in other risky behaviors that expose a person to ultraviolet (UV) radiation were more likely to tan outdoors, further increasing their risk of skin cancer. These findings may guide potential interventions to reduce UV exposure from outdoor tanning.
关于美国成年人通常或总是为了晒黑而在户外花费时间的文献有限，这里将其定义为有意户外晒黑。我们使用了 2015 年夏季消费者风尚（一项在线横断面调查，根据美国成年人人口进行了加权，n=4127）的数据，进行了未经调整和调整后的多变量逻辑回归，以检查与皮肤癌风险和有意户外晒黑相关的人口统计学特征、行为和信念因素之间的关联。研究人群中近 10%的人有意户外晒黑。户外晒黑在女性（11.4%）、非西班牙裔白人（11.5%）、18-29 岁人群（14.1%）、没有高中学历者（12.7%）和美国东北部人群（13.2%）中更为普遍。与男性相比，女性有意户外晒黑的调整后比值比（adjusted odds ratio，AOR）显著更高（AOR 1.51，95%置信区间 [CI] 1.12-2.04）；有室内晒黑或近期晒伤史的人比没有这些情况的人更高（AOR 2.61，CI 1.94-3.51；AOR 1.96，CI 1.46-2.63）；认为自己晒黑后更好看的人比不这么认为的人更高（AOR 6.69，CI 3.62-12.35）；以及在户外时不试图保护皮肤免受阳光照射的人比那些这样做的人更高（AOR 2.17，CI 1.56-3.04）。从事其他会使人暴露于紫外线（ultraviolet，UV）辐射的危险行为的成年人更有可能在户外晒黑，这进一步增加了他们患皮肤癌的风险。这些发现可能为减少户外晒黑中的 UV 暴露提供潜在干预措施的指导。
