Here is just a partial list of correlates, risk factors, and possible causes that have been the subject of serious peer-reviewed studies:
• Air pollution and proximity to freeways;
• Maternal thyroid issues;
• Autoimmune disorders;
• Induced labor;
• Preterm birth;
• Birth by cesarean section;
• Maternal and paternal obesity;
• Maternal and paternal age;
• Maternal post-traumatic stress disorder;
• Smoking during pregnancy;
• Antidepressant use during pregnancy.
Children living in an area of New York state that uses aerial pesticides to control mosquitoes have a higher rate of autism than children in neighboring areas, a new study finds.
Researchers found that children living in a swampy region in central New York were 25 percent more likely to have been diagnosed with autism or general developmental delay, compared to children in other parts of the state.
However, the findings do not prove that aerial pesticides raise the risk of autism, stressed lead researcher Dr. Steven Hicks, a pediatrician at Penn State Milton S. Hershey Medical Center, in Hershey, Pa.
“This study really brings up more questions than answers,” he said. “We need more research before taking any public action on pesticide use.”
