A separate category for missing data was included for each categorical variable with missing data. These categories are not reported in this Table.
Associations with skin cancer screening significant at P < .01 in unadjusted univariate models are denoted using bold font (ie, the proportion of individuals who were screened differed significantly among categories within a variable).
Associations with skin cancer screening significant at P < .01 in adjusted multivariable models are also denoted using bold font. This Table presents only variables found to have significant associations in indoor tanners or nontanners in the multivariable analyses. Results for nonsignificant variables in the multivariable analyses are presented in eTable 2 in the Supplement. Nonsignificant variables included sex, employment, health insurance, sexual orientation, marital status, internet use, worry about bills, availability of a place to receive health care when sick, sunburn history, and skin reaction to sun (short and long term).
