BPA in Store Receipts and Cans Raises Risk for Childhood Asthma

New research suggests that there is a connection between bisphenol A and asthma in small children according to a new study from the Mailman School of Public Health. Mark Hoffman of Science World Report reports that the Columbia Center for Children's Environmental Health evaluated a group of over 500 women and babies enrolled in a program that studies environmental exposures. Writes Hoffman:

Physicians diagnosed asthma at ages 5 to 12 based on asthma symptoms, a pulmonary function test, and medical history. A validated questionnaire was used to evaluate wheeze.

After adjusting for secondhand smoke and other factors known to be associated with asthma, the researchers found that post-natal exposure to BPA was associated with increased risk of wheeze and asthma.

While the article states that the biological connection between BPA and asthma is still unknown, this study supports existing evidence that links bisphenol A to respiratory problems. Dr. Kathleen Donohue, one of the head researchers in charge of the project, stressed the importance of sustained research of BPA's effects.

It is very important to have solid epidemiologic research like ours to give the regulators the best possible information on which to base their decisions about the safety of BPA," says senior author Robin Whyatt, DrPH, professor of Environmental Health Sciences and deputy director of the Columbia Center for Children's Environmental Health.

While Donohue and her team, as most researchers would, stress that correlation between asthma and higher bisphenol A exposure does not necessarily mean causation, the research still contributes to a body of work which is creating a composite image of the chemical's effects on the human body. While many regulatory agencies around the world have begun to heed the growing number of studies which attest to the hazards of bisphenol A, there are still companies which have not removed the chemical from their products. These studies will continue to be a resource for those who oppose the chemical's use, and will help provide consumers with a clearer picture of the impacts of the products they choose to buy.
