As is shown in Table 1, the prevalence of any past year alcohol abuse steadily increased from grade 7 to 1 year post-high school in both AAs (7.5–25.5%) and EAs (11.5–51.3%), which stabilized at 2 years post-high school (25.3% and 49.9%, respectively). AAs consistently showed lower prevalence of any alcohol abuse in the past year than EAs.
