In a study published in the journal Autism Research, researchers say that older mothers are more likely than younger mothers to have a child with autism. In addition, older fathers contribute significantly to the risk if their partners are under 30.
Roni Caryn Rabin reports in the NY Times that researchers analyzed almost five million births in California during the 1990s, and 12,159 cases of autism diagnosed in those children.

Every five-year increase in a mother’s age raised her risk of having a child with autism by 18 percent.
