For males, there were no significant differences in alcohol outcomes comparing Wave 4 to Wave 1. However, as shown in Online Table 1, estimates significantly converged between Wave 4 and Wave 3 for at-risk drinking (B=-0.56, SE=0.21, p=0.01) and average number of drinks consumed, suggesting a possible trend towards convergence as this cohort ages. Among females, the difference in the magnitude of association between race/ethnicity and average number of drinks consumed on days used diminished over time (B=-0.64, SE=0.28, p<0.01) (see Table 3), and any use as well as frequency of drunkenness exhibited non-significant negative coefficients.
