BACKGROUND
U.S. adolescents and young adults are using indoor tanning at high rates, even though it has been linked to both melanoma and squamous cell cancer. Because the availability of commercial indoor tanning facilities may influence use, data are needed on the number and density of such facilities.
METHODS
In March 2006, commercial indoor tanning facilities in 116 large U.S. cities were identified, and the number and density (per 100,000 population) were computed for each city. Bivariate and multivariate analyses conducted in 2008 tested the association between tanning-facility density and selected geographic, climatologic, demographic, and legislative variables.
RESULTS
Mean facility number and density across cities were 41.8 (SD=30.8) and 11.8 (SD=6.0), respectively. In multivariate analysis, cities with higher percentages of whites and lower ultraviolet (UV)index scores had significantly higher facility densities than those with lower percentages of whites and higher UV index scores.
CONCLUSIONS
These data indicate that commercial indoor tanning is widely available in the urban U.S., and this availability may help explain the high usage of indoor tanning.
背景
美国青少年和年轻人使用室内晒黑的比例很高，尽管这与黑色素瘤和鳞状细胞癌都有关联。由于商业室内晒黑设施的可获得性可能会影响其使用情况，因此需要有关此类设施数量和密度的数据。
方法
2006年3月，确定了美国116个大城市中的商业室内晒黑设施，并计算了每个城市的设施数量和密度（每10万人）。2008年进行的双变量和多变量分析测试了晒黑设施密度与选定的地理、气候、人口和立法变量之间的关联。
结果
各城市的设施平均数量和密度分别为41.8（标准差=30.8）和11.8（标准差=6.0）。在多变量分析中，白人比例较高且紫外线（UV）指数得分较低的城市，其设施密度显著高于白人比例较低且UV指数得分较高的城市。
结论
这些数据表明，商业室内晒黑在美国城市中广泛存在，这种可获得性可能有助于解释室内晒黑的高使用率。
