Abbreviation: aPOR, adjusted prevalence odds ratio.
Sunless tanning was defined as self-reported use of spray-on or mist tans at a tanning salon or self-applied sunless or fake tanning products in the past 12 months.
Unweighted sample sizes for reference.
Statistical significance calculated using Wald-adjusted Pearson χ2 tests (weighted percentages), Wald-adjusted t tests (mean behavioral scores), multivariable adjusted-logistic regression (aPORs), or multivariate adjusted linear regression (coefficients).
The aPORs and regression coefficients were calculated using logistic regression and linear regression analyses, respectively, controlling for age (continuous), sex, race/ethnicity, region, sexual orientation, educational level, body mass index, sun sensitivity, family history of skin cancer in a first-degree relative, and personal history of skin cancer.
Weighted mean behavioral scores. Individual participants were assigned a behavioral score between 1 (never use) and 5 (always use) based on a Likert scale for self-reported use of each sun protection method when outdoors on a sunny day for more than 1 hour.
