Early Exposure to BPA Linked to Anxiety and Hyperactivity in Boys

For related articles and more information, please visit OCA's Health Issues page and our Appetite For a Change page.

We frequently see warnings about using products that contain Bisephenol A (BPA) and many plastic products are now being made with "BPA-Free" alternatives. BPA can be found in polycarbonate plastics, canned food liners and some thermal receipts. Bisphenol A is a man-made, carbon-based product which has hormone-like properties. In 2008 a study showed that 95 percent of Americans had BPA in their urine, which goes to show just how much people are still being exposed to it. Many studies have shown that Bisphenol A is a hormone-altering chemical.

The University of California, Berkley, has released new findings from a study that shows that boys who were exposed to higher levels of Bisphenol-A as a fetus, were more likely to suffer from hyperactivity, aggression, depression and anxiety at the age of seven. To conduct the study, researchers measured BPA concentrations in 292 pregnant mothers, and then measured the BPA levels in the children at age five. At age seven the teachers and mothers of the children assessed them. Finally, at age nine they were assessed for Attention Deficit Hyperactivity Disorder (ADHD), although no link was found between BPA and ADHD in girls or boys exposed in the womb or during early childhood. No association was found in the female children, and the authors admit to being unsure of why there is a difference in the genders.

This study consisted of women and children who had lower concentrations of BPA in their systems than the U.S. average. Seventy percent of the participants lived below the poverty line, and nearly all were Hispanic. In a previous study of low-income African Americans and affects of prenatal BPA, boys had more behavioral problems, but girls had fewer problems.
