Next, a simultaneous evaluation of all predictors in a full multivariable survival model was carried out as shown regarding parameter estimates (log hazard odds) and hazard odds ratios (hOR) in Table 2 under the Full Model heading. After adjusting for all other covariates, the FH of AUDs, conduct problems, and prior marijuana use remained significant predictors of alcohol onset, and male gender became statistically significant. Interpreting the significant hazard odds ratios in the full model, offspring with an FH of alcoholism (hOR=2.01), males (hOR=1.79), more conduct problems (hOR=1.28), and prior marijuana use (hOR=2.72) all corresponded to higher hazard probabilities of lifetime alcohol use across the age range examined here.
