Further evidence linking pesticides and autism in children.

For a long time, many people have believed that genetic factors are the primary cause of autism in children. However, a group of American scientists has published new findings showing that pesticides may increase the risk of developing this incurable disease.

In a study published in the June 23rd issue of Environmental Health Perspectives, American scientists analyzed information on pesticide use in California and the living environments of approximately 1,000 mothers with children diagnosed with autism.

After examining the living conditions of these mothers during their pregnancies and leading up to their due dates, scientists discovered that approximately 30% of them lived within 1.25km to 1.75km of farmland where pesticides and herbicides were heavily sprayed.

Researchers also found that certain pesticides were commonly sprayed near the homes of mothers with children who had autism or developmental delays in cognitive and other skills. The risk of children being born with autism was also highest, especially in women in the second and third trimesters of pregnancy who lived near areas where pesticides were sprayed.

Speaking to the press, lead researcher Janie Shelton from the University of California said that this new finding further strengthens previous research showing a link between autism in children and agricultural chemicals that mothers are exposed to during pregnancy.

Although she acknowledged that more research is needed to fully determine this issue, Shelton also advised pregnant women to be careful to avoid proximity to and contact with agricultural chemicals, which could affect the health of both mother and fetus.

Autism is a neurodevelopmental disorder. Children with autism often experience delays in communication, difficulties with language use, inability to understand signs, and limited imagination. The disorder usually manifests before the age of 3 when the child becomes detached from reality and their surroundings.

Newborns may not show obvious symptoms, but from the 18th month onwards, parents and those around the child may notice clear symptoms such as the child appearing apathetic, not paying attention to surrounding activities, and not responding to adult care with facial expressions, eye contact, or smiles.

Children with autism develop physically normally, but their development is slower and less advanced than that of their peers, manifested in their inability to speak, their inability to form complete sentences, and their difficulty integrating into society.

Globally, one in every 100 children is diagnosed with autism. The United States has the highest rate of autism among children, with a statistical ratio of 1 in 68.
