After adjusting for covariates, the joint effect of exposure to advertising from all six sources at grade 6 was strongly predictive of grade 7 drinking and grade 7 intentions to drink. Youth in the 75th percentile of alcohol marketing exposure had a predicted probability of drinking that was 50% greater than that of youth in the 25th percentile.
Although causal effects are uncertain, policy makers should consider limiting a variety of marketing practices that could contribute to drinking in early adolescence.
