Although the beach is a high-risk environment for ultraviolet light exposure and subsequent skin damage, little is known about beachgoer tanning habits outside the beach setting. Our purpose was to evaluate indoor tanning and additional, nonbeach sunlight exposure in a beachgoing population.
We conducted an epidemiologic survey.
There was more use of indoor tanning salons among sunbathing beachgoers who applied little or no skin protection from the sun (50.8% [31 of 61 respondents]) compared with nonsunbathing beachgoers (22.7% [5 of 22 respondents]). In addition to increased use of tanning salons, we observed that poorly protected sunbathers tanned at locations other than the beach on a regular basis (50.8% [31 of 61 respondents]) more than nonsunbathers did (9.1% [2 of 22 respondents]).
Beachgoing sunbathers often used both natural sunlight and tanning beds, subjecting themselves to two forms of ultraviolet radiation exposure.
尽管海滩是紫外线暴露及后续皮肤损伤的高风险环境，但对于海滩游客在海滩环境之外的晒黑习惯知之甚少。我们的目的是评估海滩游客群体中的室内晒黑情况以及额外的非海滩阳光暴露情况。
我们进行了一项流行病学调查。
与不进行日光浴的海滩游客（22.7%[22名受访者中的5名]）相比，在日光浴时几乎不采取或不采取任何防晒措施的海滩游客中，使用室内晒黑沙龙的比例更高（50.8%[61名受访者中的31名]）。除了使用晒黑沙龙的比例增加外，我们还观察到，防护措施较差的日光浴者定期在海滩以外的地方晒黑（50.8%[61名受访者中的31名]），这一比例高于不进行日光浴的人（9.1%[22名受访者中的2名]）。
进行日光浴的海滩游客经常同时使用自然阳光和晒黑床，使自己暴露于两种形式的紫外线辐射之下。
