Alcohol consumption by pregnant women.

Demographic and behavioral characteristics, including use of alcohol, were investigated among 1711 women registering for prenatal care at Boston City Hospital. During personal interviews, 9% reported drinking heavily, 37% moderately, and 53% rarely or not at all. The women who drank heavily differed from the rest of the pregnant population on several traits, including age, education, use of cigarettes, marijuana and other drugs, parity, and association with others who drank heavily. Multiple regression analysis revealed that these traits had little predictive power for whether a woman was a heavy drinker. A systematic drinking history remains the most practical method in identifying problem drinkers.
