AbstractBackgroundIn France, since 2007, there is a compulsory warning recommending abstinence during pregnancy on every container of alcohol. Awareness of this warning, which consists of a small pictogram, is unknown. The aim of this study was to assess awareness of the warning and risk perceptions about prenatal drinking in pregnant and postpartum women.MethodsA cross-sectional survey was carried out by telephone five years after the introduction of the warning label. A total of 3603 pregnant or postpartum French women participated. A quota sampling method was used to ensure the sample reflected the population. Multivariate analyses examined the characteristics associated with knowledge of risks and with awareness of the warning label.ResultsThe warning label had been noticed by 66.1% of women and 77.3% of drinkers. Of those who had noticed the warning, 98.6% thought that it suggested abstinence. Overall, 40.8% of the women thought that spirits were more harmful than wine or beer, and 8.9% thought that drinking beer was recommended for lactation.ConclusionAwareness of the warning is high but knowledge about the risks associated with wine and beer is poor.Practice ImplicationsFuture information campaigns should educate women about standard drinks and their pure alcohol equivalent. They should emphasize the risks associated with drinking during breastfeeding.
