Including missing follow-ups of two participants who withdrew (2 men in Year 4) and one who died (a woman in Year 3), 98% (509 of 520) of follow-ups were successfully conducted at 1, 2, 4, 5, and 6 years. Table 1 presents demographic and drinking characteristics at baseline when the average age was 25.3 years (range 21–34) years and at year 6 when the average age was 31.4 years (range 27–40). From baseline to Year 6, alcohol drinking decreased for any drinking frequency (from 51% to 44% of days), binge-drinking frequency (from 28% to 23% of days), and maximum number of drinks consumed on one occasion (from 9.7 to 8.4). The AUDIT scores decreased but remained above cutoff threshold levels for heavy drinking (43), and drinks per drinking day and alcohol consequences did not decrease over time (Table 1).
