(FH) tree for alcohol use disorders and the FH Research Diagnostic Criteria for drinking consequences(37), an alcohol Timeline Follow-back for past month drinking(38), the Alcohol Use Disorders Identification Test (AUDIT (39)), and the Drinker Inventory of Consequences (Dr-InC2R (40). Heavy drinkers (HD) were defined as weekly binge drinkers (consuming >5 drinks for men, >4 for women, per occasion 1–4 times weekly) with at least 10 but no more than 40 drinks consumed per week for at least the past two years. Light drinkers (LD) averaged consuming 1–5 drinks per week with no/rare binge episodes (<5 times/year). These criteria were based upon established guidelines(41–43) and were consistent with prior studies (44–50). Positive FH was defined as having at least one biological first-degree biological relative or two or more second-degree relatives with alcohol use disorders.
