More American children than previously thought may be suffering from neurological damage because their mothers drank alcohol during pregnancy, according to a new study.
The study, published Tuesday in the journal JAMA, estimates that fetal alcohol syndrome and other alcohol-related disorders among American children are at least as common as autism. The disorders can cause cognitive, behavioral and physical problems that hurt children’s development and learning ability.
The researchers evaluated about 3,000 children in schools in four communities across the United States and interviewed many of their mothers. Based on their findings, they estimated conservatively that fetal alcohol spectrum disorders affect 1.1 to 5 percent of children in the country, up to five times previous estimates. About 1.5 percent of children are currently diagnosed with autism.
