If two siblings are not born early enough, there is a greater risk of autism, a study suggests.
In the survey, 1.1 million children were surveyed and found that not only the short intervals between pregnancies could increase the risk of autism, but could potentially be too much longer. Based on previous research results, it can be said that between two pregnancies the ideal elapsed time is between 2 and 5 years. So the greatest currency is the risk of diminishing autism, "says research leaders Dr. Agustin Conde-Agudelowho is a WHO researcher and a fellow at the University of Valle, Colombia."For the time being, we do not know what may be the reason for this, and the short intervals between pregnancies may increase the risk not only of autism but also of other neurologic developmental disorders. In any case, - adds.

When's the Next Baby Coming?
Research published in Pediatrics does not seem to suggest that too little or too much age between two siblings causes autism, but all signs point to an increase in risk. Currently 86 out of 1 American children with autism spectrum disorder are diagnosed, often with socialization and communication problems. Symptoms usually appear before the age of 3 years.
It is not known exactly what causes autism, according to experts, genetics, environmental factors, the health status of parents, and the lifestyles of pregnant women all play a role in the development of the disorder.
