In comparison, LGC models within the older FTC cohort (Table 4) demonstrated that BeerPref and EXT PGSs were associated with a higher intercept for Heavy drinking (β=0.047–0.059, p<1.03E-05). EXT PGSs also predicted higher intercept values for gEtOH (β=0.197, p=1.12E-06). These differences likely reflect the older age of the sample, as the intercept now references drinking behaviors in young adulthood, after the period of sharp increase observed in adolescence in other cohorts. Again, no significant prediction from the PGSs was seen for the latent growth factors representing longitudinal changes in AUBs.
