Pregnant when parents no longer young age not only endanger the safety of mothers and babies in the womb. Recent research has found age parents also affect the health of the baby.
The study found children were more likely to have an increased risk of autism if the mother and father were aged 35 years or older at the time of conception.
According to researchers from Denmark who worked with researchers from Cambridge University shows that risk is 27 percent higher than younger couples. If both parents are in their 30s, the risk did not increase even though one of the older parent.
However, if one parent aged 35-40 years, the risk of autism was more pronounced in women older age (65 percent) than fathers (44 percent).
Researchers analyzed 1.3 million children born in Denmark between the years 1980-2003. Of these, approximately 9,556 children diagnosed with autism spectrum disorders by a psychiatrist after referral for treatment. Including Asperger's syndrome and other disorders.
Professor of a university in Denmark reveals mutation in sperm may increase the risk of autism and a new mutation in the egg increases the risk of autism.
"When a mutation occurs in both, pairing high risk of having a child with autism than couples who only have one particular mutation," he said.
Although this research shows parental age plays a role, but further explanation is needed. "This study shows that there is a relationship between parental age with autism in children, but more research is needed. We know little chain of biological cause of autism," he added.
