Paternal and Maternal Age, Crucial in Children With Autism

Older paternal and maternal ages are jointly linked with having a child who suffers from autism, as per a research which recently got in print. This research was led by the researchers at the University of Houston. A team of researchers evaluated 68 age and gender matched case-regulate pairs from their investigation in Jamaica. This research regarding autism was been conducted at the UT Health, in collaboration with the Mona Campus, the University of the West Indies, Kingston, Jamaica.  The earlier studies had many discrepancies but this study and its findings will put to rest earlier discrepancies.

The National Institute for Neurologic Disorders and Stroke identifies that “twin and family studies strongly suggest that some people have a genetic predisposition to autism.   There are a number of studies in progress to determine the specific genetic factors associated with the development of ASD.  In families with one child with ASD, the risk of having a second child with the disorder is approximately 5 percent, or one in 20.  This is greater than the risk for the general population.  Researchers are looking for clues about which genes contribute to this increased susceptibility.  In some cases, parents and other relatives of a child with ASD show mild impairments in social and communicative skills or engage in repetitive behaviors.  Evidence also suggests that some emotional disorders, such as bipolar disorder, occur more frequently than average in the families of people with ASD.”

The earlier studies proved that only the paternal or just the maternal age was associated with having a child who suffered from autism, submits the director of UT Health, Rahbar, Ph.D. He is a lead researcher and professor of biostatistics and Epidemiology at the University of Houston.  He says that the recent studies proved that the age of mother and father are jointly responsible and linked with the autism in their children, Rahbar submitted. He is also the director of (BERD) Biostatistics, Epidemiology and Research Design. In this study, the investigators discovered that mothers whose children suffered from autism were on average 6.5 years elder to the mothers whose child did not suffer from this disease. The equivalent age of the father was 5.9 years.

In earlier studies, Rahbar said that due to the statistical techniques used, it was not easy to access both paternal and maternal age, due to the joint risk factor called the multicollinearity. The researcher was able to apply more difficult statistical models to eliminate the problem. The disorders of Autism Spectrum are complicated, behavioral and neurodevelopmental disorders which are characterized by the impairments in the following:

  • Social interaction
  • Repetitive and communication behavior
  • Sometimes obsessive behavior

As per the CDC, a conventional estimate says that one in every 100 children suffers from ASD.
