Early-onset drinkers were more likely to participate in the sexual behaviors as compared with nondrinkers; they were 24 times more likely to report having had sex, 4 times as likely to report multiple partners, and almost 6 times more likely to have sex without using a condom, compared with nondrinkers. Comparisons between nondrinkers and late-onset drinkers revealed elevated ORs for all of the sexual behaviors; the latter were almost 12 times 4 four times as likely to have sex without using a condom. Although there were no differences between early- and late-onset drinkers for the individual sexual behaviors, early-onset drinkers were significantly more likely than their late-onset counterparts to participate in one of the sexual behaviors.
