The risk increases with age Autism Mother

Compared to men, women who have babies in a young age no longer more increases the risk of children with austisme. Thus the results of new studies that analyzed the findings of more than 5 million births.

The comparison is this: women aged over 40 years are at risk for getting 50 percent of children with autism than those who gave birth at the age of 20 years. The study also states, the risk of less than 4 per 1,000 births. While the risk of men aged over 40 years is higher than 36 percent of men who have children in the age of 20 years.

The discovery, which was released in the Journal of Autism Research in February of this issue, contrary to other studies which say that paternal age plays a greater role than the age of the mother. The researchers and other autism experts say that this new study is more convincing, partly because the scope of a broader research. Mature-old mother were found to have an increased risk for children with genetic disorders, and genes predicted role in autism.

Autism is a disorder that developed, which led to behavior problems, communication, and socialization of mild or severe.

Small risk
However, according to Maureen Durkin, researchers from the University of Wisconsin who also studied the influence of parental age on autism, this increased risk was small. Many babies born to mothers aged mature does not have autism. Therefore according to him, low risk for autism is just a message that needs to be considered by prospective parents.

This study studied the 5.6 million babies born in California between January 1, 1990 and December 31, 1999, and cases of autism are diagnosed before the age of 6 years. In a total of more than 13,000, while the study analyzed 12,159 autistic children in which parents are also unknown age.

The researchers also take into account factors that may affect the diagnosis of autism, including parents' education and race.

Meanwhile, Catherine Lord, director of the Autism and Communication Disorders Center at the University of Michigan, said that this study is more powerful than previous studies that focus on paternal age. This, he says, giving a fuller picture of what is happening.

Recent data says that 1 in 100 children in the United States have autism, a figure that appears to have increased in the last decade. The experts believe that this increase reflects better awareness and expanding the definition of autism than the increase of children who have it.

Babies born to older mothers are aged has increased in recent years, but may only contribute a small portion of the increase in cases, according to the opinion of one who is also author of the study UC-Davis researchers, Irva Hertz-Picciotto.
