Delaying Parenthood Increases Risk for Autism in Children
Parents over 40 years old have a higher chance of having an autistic child, according to a new study by the Kaiser Permanente Division of Research in Oakland, CA.
Women over 40 years have a 30 percent greater risk and men over 40 years have a 50 percent greater risk of having a child born with autism than parents ages 25 to 29. The researchers are uncertain why risk increases with age.
Lisa Croen and her colleagues analyzed 132,844 birth records from Kaiser Hospitals in northern California between 1995 and 1999. They adjusted for factors like the parents' educational levels, race and ethnicity before they concluded that parents' ages increases the risk for autism.
This study appears in the April issue of the Archives of Pediatrics and Adolescent Medicine.
Asperger’s schools can help children with Asperger's Syndrome, high-functioning Autism, and other conditions of the Autism Spectrum Disorders. Cedars Academy offers a year-long Asperger’s school and Talisman offers a semester-long academic Asperger’s school.
