Women who take prenatal multivitamin supplements may reduce their infants’ risk of developing autism, suggests a study in JAMA Psychiatry. Researchers followed more than 45,000 children born in Israel from 2003 to 2007, and gathered data from prescription records on whether their mothers had been prescribed prenatal multivitamins A, B, C and D. Compared with women who did not receive the vitamins, women who were dispensed the vitamins at any time before pregnancy had a 61 percent lower chance of having a child with autism. Those who were dispensed the vitamins during pregnancy had a 73 percent lower chance, even after controlling for factors such as the child’s sex, socioeconomic status and parents’ age.
