Abstract: 

Reviewing a larger population than in any other study of its kind, the California Department of Public Health (CDPH) has found that as parents age their risk of giving birth to a child with autism increases modestly. Published in the American Journal of Epidemiology, the new CDPH study shows that for each 10-year increase in a mother’s age, the risk of autism increased by about 38 percent. For each 10-year increase in a father’s age, the risk of autism increased by about 22 percent.
