Boys exposed prenatally to a common chemical used in plastics may be more likely to develop symptoms of anxiety and depression at age 10-12. The new study by researchers at the Columbia Center for Children’s Environmental Health (CCCEH) within the Mailman School of Public Health examined early life exposure to the chemical Bisphenol A (BPA). Results are published in the journal Environmental Research.
BPA is a component of some plastics and is found in food containers, plastic water bottles, dental sealants, and thermal receipt paper. In the body, BPA is a synthetic estrogen, one of the class of chemicals known as “endocrine disruptors.” The Columbia researchers, led by Frederica Perera, PhD, DrPH, director of CCCEH, previously reported that prenatal exposure to BPA was associated with emotionally reactive and aggressive behavior, and more symptoms of anxiety and depression in boys at age 7-9.
