Table 2 presents the unadjusted, partially adjusted, and fully adjusted Cox proportional hazard models of the risk for onset of drinking as a function of divorce/separation. The unadjusted models revealed that the estimated odds of consuming a full drink were greater for girls than for boys and increased with age. For girls, the odds of consuming a full drink were 49% higher (HR=1.49; 95% CI: 1.14, 1.94) the odds for boys, and the odds increased by 31% (HR=1.31; 95% CI: 1.14, 1.52) with each year of age. Importantly, youth who experienced divorce/separation were at significantly greater risk of initiation than those who did not (HR=1.65; 95% CI: 1.26, 2.14). This association remained significant in adjusted models controlling for sex, age, and SES (HR=1.55; 95% CI: 1.17, 2.05).
