Exposure to chemical BPA before birth linked to behavioral, emotional difficulties in girls
Date:10/23/2011

d that maternal BPA concentrations were similar between the first sample and birth. The children's BPA levels decreased from ages 1 to 3, but were higher and more variable than that of their mothers.

After adjusting for possible contributing factors, increasing gestational BPA concentrations were associated with more hyperactive, aggressive, anxious, and depressed behavior and poorer emotional control and inhibition in the girls. This relationship was not seen in the boys.

The study confirms two prior studies showing that exposure to BPA in the womb impacts child behavior, but is the first to show that in utero exposures are more important than exposures during childhood, Braun said. "Gestational, but not childhood BPA exposures, may impact neurobehavioral function, and girls appear to be more sensitive to BPA than boys," he said.

Although more research is needed to fully understand the health effects of BPA exposure, clinicians can advise those concerned to reduce their BPA exposure by avoiding canned and packaged foods, thermal paper sales receipts, and polycarbonate bottles with the number 7 recycling symbol, the authors wrote.

Bruce Lanphear of Simon Fraser University was senior author of the study.
