Abstract

BACKGROUND:

Prenatal alcohol exposure is a leading preventable cause of birth defects and developmental disabilities in the United States.

DESIGN:

A randomized controlled trial (2002-2005; data analyzed 2005-2006) of a brief motivational intervention to reduce the risk of an alcohol-exposed pregnancy (AEP) in preconceptional women by focusing on both risk drinking and ineffective contraception use.

SETTING/PARTICIPANTS:

A total of 830 nonpregnant women, aged 18-44 years, and currently at risk for an AEP were recruited in six diverse settings in Florida, Texas, and Virginia. Combined settings had higher proportions of women at risk for AEP (12.5% overall) than in the general population (2%).

INTERVENTIONS:

Participants were randomized to receive information plus a brief motivational intervention (n=416) or to receive information only (n=414). The brief motivational intervention consisted of four counseling sessions and one contraception consultation and services visit.

MAIN OUTCOME MEASURES:

Women consuming more than five drinks on any day or more than eight drinks per week on average, were considered risk drinkers; women who had intercourse without effective contraception were considered at risk of pregnancy. Reversing either or both risk conditions resulted in reduced risk of an AEP.

RESULTS:

Across the follow-up period, the odds ratios (ORs) of being at reduced risk for AEP were twofold greater in the intervention group: 3 months, 2.31 (95% confidence interval [CI]=1.69-3.20); 6 months, 2.15 (CI=1.52-3.06); 9 months, 2.11 (CI=1.47-3.03). Between-groups differences by time phase were 18.0%, 17.0%, and 14. 8%, respectively.

CONCLUSIONS:

A brief motivational intervention can reduce the risk of an AEP.
