Indoor tanning beds (ITBs) emit UV light at high intensity and have been classified as carcinogenic to humans by the World Health Organization since 2009. We are the first to study the role of state laws prohibiting youths from indoor tanning using a difference-in-differences research design. We find that youth ITB prohibitions reduced population search intensity for tanning-related information. Among white teen girls, ITB prohibitions reduced self-reported indoor tanning and increased sun protective behaviors. We also find that youth ITB prohibitions significantly reduced the size of the indoor tanning market by increasing tanning salon closures and reducing tanning salon sales.
室内晒黑床(ITBs)会高强度发射紫外线,自2009年起就被世界卫生组织列为对人类致癌物质。我们首次运用双重差分研究设计来探究禁止青少年使用室内晒黑床的州法律所起的作用。我们发现,禁止青少年使用室内晒黑床的法律降低了民众对晒黑相关信息的搜索强度。在白人少女中,禁止使用室内晒黑床的法律减少了她们自我报告的室内晒黑行为,并增加了防晒行为。我们还发现,禁止青少年使用室内晒黑床的法律通过增加晒黑沙龙的关闭数量和减少晒黑沙龙的销售额,显著缩小了室内晒黑市场的规模。
