To our knowledge, no study has examined age- and sex-specific associations between indoor tanning and melanoma to determine if these trends could be due to greater indoor tanning use among younger women. OBJECTIVE To examine associations between indoor tanning and melanoma among men andwomen younger than 50 years. DESIGN, SETTING, AND PARTICIPANTS Population-based case-control study conducted in Minnesota of 681 patients (465 [68.3%] women) diagnosed as having melanoma between 2004 and 2007, and 654 controls (446 [68.2%] women), ages 25 to 49 years. EXPOSURE Indoor tanning, defined as any use, first age of use, and total sessions. MAIN OUTCOMES AND MEASURES Crude and adjusted odds ratios (ORs) and 95%CIs were calculated for melanoma in relation to indoor tanning exposure for men and women by diagnosis or reference age (>30, 30-39, 40-49 years). Sex-specific associations for indoor tanning and melanoma by anatomic site were examined. RESULTS Compared withwomen aged 40 to 49 years,women younger than 40 years initiated indoor tanning at a younger age (16 vs 25 years, P >.001) and reported more frequent indoor tanning (median number of sessions, 100 vs 40, P >.001). Women younger than 30 yearswere 6 times more likely to be in the case than the control group if they tanned indoors (crude OR, 6.0; 95%CI, 1.3-28.5). Odds ratioswere also significantly elevated amongwomen, ages 30 to 49 years (adjusted OR, 3.5; 95%CI, 1.2-9.7 forwomen 30-39 years; adjusted OR, 2.3; 95% CI, 1.4-3.6 forwomen 40-49 years); a dose responsewas observed amongwomen regardless of age. Among men, results by agewere inconsistent. The strongest OR for indoor tanning by anatomic sitewas for melanomas arising on the trunk of women (adjusted OR, 3.7; 95%CI, 1.9-7.2). CONCLUSIONS AND RELEVANCE Indoor tanning is a likely factor for the steeper increase in melanoma rates in the United States among younger women compared with men, given the timing of when women initiated indoor tanning relative to diagnosis. The melanoma epidemic can be expected to continue unless indoor tanning is restricted and reduced. © 2016 American Medical Association. All rights reserved.
