To promote abstinence from alcohol during pregnancy, a health warning is now printed on alcoholic beverage packaging. The implementation of this measure was accompanied by a press campaign and extensive media coverage. The authors conducted a study to assess changes in the general public’s knowledge on this subject. Two telephone surveys were conducted in 2004 and 2007 with two independent samples representative of the French population aged 15 and older. These samples (1,003 and 1,006 people, respectively) were constructed using the quota method. It appears that awareness of the recommendation to avoid alcohol during pregnancy was higher in 2007 than in 2004 (87% of respondents vs. 82%). In 2007, 30% believed that the risk to the fetus begins with the first drink (vs. 25% in 2004). For 27% of respondents in 2007 (22% in 2004), the risk is equivalent throughout pregnancy. In both surveys, one in two people believed that drinking beer or wine during pregnancy is as dangerous as drinking hard liquor. These results indicate that while awareness of the principle of equivalence among different alcoholic beverages has not increased, the social norm regarding alcohol consumption during pregnancy appears to have shifted toward “zero alcohol.” These trends suggest a positive impact of media coverage on this topic.
