To assess whether an association exists between financial links to the indoor tanning industry and conclusions of indoor tanning literature.
Systematic review.
PubMed, Embase, and Web of Science, up to 15 February 2019.
Articles discussing indoor tanning and health were eligible for inclusion, with no article type restrictions (original research, systematic reviews, review articles, case reports, editorials, commentaries, and letters were all eligible). Basic science studies, articles describing only indoor tanning prevalence, non-English articles, and articles without full text available were excluded.
691 articles were included in analysis, including empiric articles (eg, original articles or systematic reviews) (357/691; 51.7%) and non-empiric articles letters (eg, commentaries, letters, or editorials) (334/691; 48.3%). Overall, 7.2% (50/691) of articles had financial links to the indoor tanning industry; 10.7% (74/691) articles favored indoor tanning, 3.9% (27/691) were neutral, and 85.4% (590/691) were critical of indoor tanning. Among the articles without industry funding, 4.4% (27/620) favored indoor tanning, 3.5% (22/620) were neutral, and 92.1% (571/620) were critical of indoor tanning. Among the articles with financial links to the indoor tanning industry, 78% (39/50) favored indoor tanning, 10% (5/50) were neutral, and 12% (6/50) were critical of indoor tanning. Support from the indoor tanning industry was significantly associated with favoring indoor tanning (risk ratio 14.3, 95% confidence interval 10.0 to 20.4).
Although most articles in the indoor tanning literature are independent of industry funding, articles with financial links to the indoor tanning industry are more likely to favor indoor tanning. Public health practitioners and researchers need to be aware of and account for industry funding when interpreting the evidence related to indoor tanning.

评估与室内晒黑行业的财务联系与室内晒黑文献结论之间是否存在关联。
系统评价。
PubMed、Embase 和 Web of Science,截至 2019 年 2 月 15 日。
讨论室内晒黑与健康的文章符合纳入标准,对文章类型没有限制(原始研究、系统评价、综述文章、病例报告、社论、评论和信件均符合条件)。基础科学研究、仅描述室内晒黑流行率的文章、非英语文章以及无法获取全文的文章均被排除在外。
纳入分析的文章共有 691 篇,包括实证文章(例如原始文章或系统评价)(357/691;51.7%)和非实证文章(信件)(334/691;48.3%)。总体而言,7.2%(50/691)的文章与室内晒黑行业有财务联系;10.7%(74/691)的文章支持室内晒黑,3.9%(27/691)为中立,85.4%(590/691)对室内晒黑持批评态度。在没有行业资助的文章中,4.4%(27/620)支持室内晒黑,3.5%(22/620)为中立,92.1%(571/620)对室内晒黑持批评态度。在与室内晒黑行业有财务联系的文章中,78%(39/50)支持室内晒黑,10%(5/50)为中立,12%(6/50)对室内晒黑持批评态度。室内晒黑行业的支持与支持室内晒黑显著相关(风险比 14.3,95%置信区间 10.0 至 20.4)。
尽管室内晒黑文献中的大多数文章都独立于行业资助,但与室内晒黑行业有财务联系的文章更有可能支持室内晒黑。公共卫生从业者和研究人员在解释与室内晒黑相关的证据时,需要意识到并考虑行业资助。
