In the model not controlling for T1 alcohol problems, those with the GG genotype had greater T2 alcohol problems. Non-Hispanic Caucasian ancestry (marginal), older age, and female gender predicted higher T2 alcohol problems. No other covariates predicted T2 alcohol problems. Higher sensation seeking and higher impulsivity predicted greater T2 alcohol problems. All results were identical in the model that controlled for T1 alcohol problems (which was also a significant predictor) except that non-Hispanic Caucasian ancestry significantly and female gender marginally significantly predicted T2 alcohol problems.
