age of parents and autism
Print E-Mail. New York, N.Y. (June 9, 2015) - The largest-ever multinational study of parental age and autism risk, funded by Autism Speaks, found increased autism rates among the children of teen moms and among children whose parents have relatively large gaps between their ages. Autism Risk Rises With Mother's Age. Feb. 8, 2010 -- The older a mother is when she gives birth, the higher her child's risk of autism, new data show. A smaller effect also is seen for the age of the father, but only when the child is born to a father over age 40 and a mother under age 30. The new findings come from a comparison of reported autism cases in California to state singleton birth records from 1990 to 1999. The size allowed us to look at the relationship between parents’ age and autism at a much higher resolution – under a microscope, if you will.”. The study included Denmark, Norway, Sweden, Israel, and Western Australia and observed the rates of autism of 5,766,794 children born between the years of 1985 to 2004. Offit and His Critics: Part 2. NOTE: We're bringing you this series, re-crafted for 2017, by Richard P. Milner of Public Affairs Media during Autism Action Month. Dr. Paul Offit has led the charge against any and all in our community, doctors, scientists, parents, educators, film makers, who question vaccine safety. By Richard P. Milner. The authors of the epidemiological study, published February 8 in Autism Research, examined the parental age of more than 12,000 children with autism and nearly five million control children between 1990 and 1999, all living in California. Largest-ever study of parental age and autism finds increased risk with teen moms. New York, N.Y. (June 9, 2015) - The largest-ever multinational study of parental age and autism risk, funded by Autism Speaks, found increased autism rates among the children of teen moms and among children whose parents have relatively large gaps between their ages. The researchers found that mothers over 40 had a 51 percent higher risk of having a child with autism than mothers 25 to 29, and a 77 percent higher risk than mothers under 25. Autism—a developmental disorder characterized by impaired social interaction and communication—appears to be on the rise. Teen mothers were 18 percent more likely to have children with autism than mothers in their 20s. Mothers in their 40s were 15 percent more likely to have children with autism than mothers in their 20s. Dads aged 35-44 who had an age gap of 10 years or more with their partners were also at a somewhat increased risk. Scientists still aren't yet sure why both younger and older parental age seem to be risk factors. “Although parental age is a risk factor for autism, it is important to remember that, overall, the majority of children born to older or younger parents will develop normally,” study co-author Dr. Sven Sandin, a medical epidemiologist at Mount Sinai and the Karolinska Institute, said in a statement. The proportion of parents of autistic children with fewer than 24 years of combined education in the study was smaller than that of control birth parents, (19 percent and 36 percent, respectively). Other contributors to the increasing incidence of autism remain unclear.
