MedicalResearch.com: What is the background for this study?

Response: Maternal folic acid taken near conception has been linked to reduced risk for autism in the child in previous studies.

Separate studies show that exposure to pesticides during pregnancy is associated with increased risk for autism.

Animal studies demonstrate that folic acid and other B-vitamins can attenuate effects of certain environmental contaminants, including pesticides.

This case-control study examined combined maternal folic acid and pesticide exposures in relation to autism in the child.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Altered stress reactivity, alterations in cytokines and a high incidence of gastrointestinal disturbances have all been observed in autism spectrum disorder (ASD). We wished to examine the interactions between these factors.

What we found was that patients with greater stress reactivity, as indicated by cortisol response in the testing environment, had greater symptomatology involving the lower gastrointestinal tract, which was predominated by constipation.
