Children exposed to the chemical bisphenol A, or BPA, may be at an increased risk for asthma, a new study suggests.

During the study, kids who had greater exposure to BPA at ages 3, 5 and 7 were more likely to be diagnosed with asthma before age 12 than children who had less exposure.

 

BPA is found in some plastics, canned food containers and other food packaging, and most people have detectable levels of the chemical in their urine. Previous studies have linked BPA to a number of health conditions, including childhood obesity and behavior problems.

 

The new study is the first to report a link between BPA exposure during childhood and an increased risk for asthma. An earlier study found a link between BPA exposure in the womb during the second trimester of pregnancy, and an elevated risk of wheezing at age 3.
