n=sample size; *weighted percentages; OR=odds ratio (crude); aOR=adjusted odds ratio; CI=confidence interval

Model 1: ORs estimated through bivariate analyses of the association between each variable and suicide attempts

Model 2: aORs for the association between each sociodemografic variable and suicide attempts (entered simultaneously)

Model 3: aORs obtained introducing all variables simultaneously
