Indoor tanning and sunburns, particularly during adolescence and young adulthood, increase the risk of developing skin cancer.
To examine the trends in the prevalence of indoor tanning and the association between indoor tanning and sunburn among US high school students.
DESIGN, SETTING, AND PARTICIPANTS: This study pooled and examined cross-sectional data from the 2009, 2011, 2013, and 2015 national Youth Risk Behavior Survey. During 2009, 2011, 2013, and 2015, the overall response rates were 71%, 71%, 68%, and 60%, respectively, and unweighted sample sizes were 16 410, 15 425, 13 538, and 15 624, respectively. It included nationally representative samples of US high school students. Data were collected during the spring semester (January to June) in each survey cycle beginning February 9, 2009, through June 18, 2015.
Prevalence of indoor tanning in the past year from 2009 to 2015 and its association with sunburn in 2015.
Among high school students in the United States, the prevalence of indoor tanning decreased from 15.6% (95% CI, 13.7%-17.6%) in 2009 to 7.3% (95% CI, 6.0%-8.9%) in 2015. Decreases in indoor tanning were found among male (from 6.7% in 2009 to 4.0% in 2015) and female (from 25.4 % in 2009 to 10.6 % in 2015) students overall, non-Hispanic white (from 21.1 % in 2009 to 9.4% in 2015) and Hispanic (from 8.2% in 2009 to 4.7% in 2015) students overall, and all age groups. Among non-Hispanic white female students, the prevalence decreased from 37.4% (95% CI, 33.6%-41.4%) in 2009 to 15.2% (95% CI, 11.7%-19.5%) in 2015. In 2015, indoor tanning was associated with sunburn in the adjusted model: 82.3% (95% CI, 77.9%-86.0%) of indoor tanners had at least 1 sunburn during the preceding year compared with 53.7% (95% CI, 48.9%-58.4%) of those who did not engage in indoor tanning (P < .001).
Despite declines in the prevalence of indoor tanning from 2009 to 2015 among high school students nationwide, indoor tanning remains commonplace among certain subgroups, especially non-Hispanic white female students. Three-quarters of those who engaged in indoor tanning had experienced at least 1 sunburn. Efforts by the public health and medical communities are needed to further reduce the prevalence of indoor tanning and sunburn and thus prevent future cases of skin cancer.
室内晒黑以及晒伤，尤其是在青少年期和青年期，会增加患皮肤癌的风险。
研究美国高中生室内晒黑流行趋势以及室内晒黑与晒伤之间的关联。
设计、背景和参与者：本研究汇总并分析了2009年、2011年、2013年和2015年全国青少年风险行为调查的横断面数据。在2009年、2011年、2013年和2015年，总体回复率分别为71%、71%、68%和60%，未加权样本量分别为16410、15425、13538和15624。研究纳入了具有全国代表性的美国高中生样本。在每个调查周期的春季学期（1月至6月）收集数据，调查周期从2009年2月9日开始至2015年6月18日结束。
2009年至2015年过去一年室内晒黑的流行率及其与2015年晒伤的关联。
在美国高中生中，室内晒黑的流行率从2009年的15.6%（95%CI，13.7%-17.6%）降至2015年的7.3%（95%CI，6.0%-8.9%）。总体而言，男性（从2009年的6.7%降至2015年的4.0%）和女性（从2009年的25.4%降至2015年的10.6%）学生、非西班牙裔白人（从2009年的21.1%降至2015年的9.4%）和西班牙裔（从2009年的8.2%降至2015年的4.7%）学生以及所有年龄组的室内晒黑率均有所下降。在非西班牙裔白人女性学生中，可以看到流行率从2009年的37.4%（95%CI，33.6%-41.4%）降至2015年的15.2%（95%CI，11.7%-19.5%）。在2015年，校正模型中室内晒黑与晒伤相关：在前一年，82.3%（95%CI，77.9%-86.0%）的室内晒黑者至少有一次晒伤，而未进行室内晒黑的人这一比例为53.7%（95%CI，48.9%-58.4%）（P < .001）。
尽管2009年至2015年全国高中生室内晒黑的流行率有所下降，但在某些亚组中，尤其是非西班牙裔白人女性学生中，室内晒黑仍然很常见。四分之三进行室内晒黑的人至少有过一次晒伤。公共卫生和医学界需要做出努力，进一步降低室内晒黑和晒伤的流行率，从而预防未来的皮肤癌病例。
