This research project aimed to estimate the global prevalence of alcohol use during pregnancy and Foetal Alcohol Syndrome (FAS) in the general population. It finds that alcohol use during pregnancy is relatively common and that Europe has particularly high rates of women who consume alcohol during pregnancy, and consequently, the highest rate of FAS. The paper provides a discussion of the social and cultural factors that may influence the prevalence of alcohol use during pregnancy, and suggests that more effective prevention strategies be targeted towards particular at-risk populations.
