^*Confounders adjusted for were the number of male intercourse partners and scores on the AUDIT, Readiness for Change for Contraception, Processes of Change for Alcohol, Decision Balance Scale for Alcohol, and Temptation for Alcohol (BSCQ-T).

AEP, alcohol-exposed pregnancy; CI, confidence interval; OR, odds ratio.
