Autism and the Environment

A new meta-analysis study of 100 million US medical records from the University of Chicago links environmental pollution, such as pesticides,  to autism and intellectual disability (ID). The researchers found that autism and ID were "correlated at the county level with incidences of genital malformations in newborn males," according to The Examiner. The researchers claim that autism is strongly correlated with the incidence of congenital genital malformation in males.

There are certain times during a pregnancy where the fetus is particularly sensitive to small molecule environmental pollutants, like pharmaceuticals and pesticides. Some of these molecules alter the normal development of the fetus, through unknown processes. The researchers studied genital malformations in females and males but found that the congenital malformation - autism link was much stronger in boys.

The study's main author is quick to point out that this study does not count out genetic and other factors for autism. Nor does it directly point to the environment as the cause for autism, but it does point to a strong argument for an environmental role.
