Consumption of alcohol was investigated in two groups of pregnant women: an intervention group (n = 58) (two structured interviews during pregnancy including counseling focused on reduction of alcohol consumption and potential benefits to the fetus, and interview after delivery), and a control group (n = 74) (interview after delivery). Prepregnancy 80% of the women were light or moderate alcohol consumers, and 20% teetotalers. Pregnancy considerably reduced alcohol consumption in both groups. 66% abstained from alcohol during pregnancy, and use of liquor nearly ceased. The changes in alcohol consumption occurred independently to the intervention program. Strategy for reducing alcohol consumption during pregnancy should include a structured alcohol anamnesis at the first ante-natal visit, accompanied by counseling focused on reduction of alcohol consumption. More extensive intervention programs may be reserved for pregnancies at higher risk (high-consumers, abusers).
