(CBS News) -- Bisphenol A (BPA) is often used to line food and beverage cans as well as to keep plastics flexible, but a new study suggests the compound can leach into the foods we eat.
BPA has been linked to behavior problems, obesity, hormone abnormalities and even kidney and heart problems. Now, new research from scientists at the Columbia Center for Children's Environmental Health has found a link between the compound and an increased risk for asthma.
"Our study found that routine low doses of exposure were associated with increased odds in wheezing," said lead author Dr. Kathleen Donohue, an assistant professor of medicine at Columbia University College of Physicians and Surgeons and an investigator at the center.
Donohue and her colleagues followed 568 women participating in a study on environmental exposures to mothers and newborns. They measured the BPA levels in the women's urine during their third trimester of pregnancy and also tested their kids' urine for BPA when they were aged 3, 5 and 7. At ages 5 and 12, based on their symptoms, tests and medical history, their physicians diagnosed the children who met the criteria for asthma with the respiratory disorder.
