confidence intervals are reported for the multivariable models. ORs reflect the increased odds of the presence of the risky behavior as compared to the lower ordered drinking group, after adjusting for all other variables in the model. Nondrinkers are used as the reference group for the nondrinkers vs. the early-onset drinkers, and the nondrinkers vs. the late-onset drinkers; early drinkers are the referent group for the early-onset vs. the late-onset drinkers. Multivariable models could not be explored for some variables (i.e., binge eating when drinking and early marijuana use) due to sparse data in the cross-tabulations.
