How common is FAS?
The reported prevalence rates of FAS vary widely depending on the population studied and the intensity of case ascertainment. In the general population, estimates vary from 0.7 cases per 1,000 to 1.0 cases per 1,000 live births with higher rates (e.g., 3 per 1,000 live births) among American Indian and Alaska natives. Other neurodevelopmental effects of alcohol are believed to occur more frequently.
