  1. 95 % CI 95 % confidence interval, OR odds ratio aOR adjusted odds ratio, No. number, STI+ diagnosed or self-reported one or more sexually transmitted diseases in the last 12 months
  2. Bold printed statistics differ, p-values < .05 are considered significant
  3. aVariables are a priori included in multivariable analyses
  4. bFactors differ significantly between databases, p-values < .05 are considered significant
