Children with autism in older parents

A recent study shows that the age of the mother, as well as the father, is a risk factor for conceiving a child, which is more susceptible to autism. However, the researchers point out that the risk of having a child with ASD (autism) is very low, even for very old parents. A number of studies have been conducted on the influence of maternal age on autism, but the results have not been complete. "The father's age has been under-studied," says Dr. Lisa A. Croen. "Our findings link autism to parents' age, but the effect of this risk is small."

"Our findings link autism to parents' age, but the effect of this risk is small."
According to Croen, from Kaise Permanente in Oakland, California, the new findings have no strong argument for or against conceiving a child even at a young age.

The study, which is reported in the Pediatric Archives, involved all single children in parents who were born in Kaieser Permanente between 1995-1999. Of the children studied (593), 132 were diagnosed with autism, and 251 were not.
With every 10 years of the mother, the risk of autism increases by 31%, while the father's 10 years increases by 28%. Compared with parents between the ages of 25-29, mothers and fathers 40 years have a risk of 27%, respectively 52% of conceiving with a child with autism. The relationship between parents' age and autism was stronger in girls than boys, but the association is not statistically significant.
Croen notes that she was not surprised when the findings from previous research were based on this connection and that the number of childhood illnesses was associated with the advanced age of parents. She added that her study group explored this topic further by using information from across the state of California and proposing these findings for publication.
