No Proven Link between Early BPA Exposures and Childhood Asthma
WASHINGTON (March 1, 2013) – The following statement can be attributed to Steven G. Hentges, Ph.D., of the Polycarbonate/BPA Global Group, American Chemistry Council (ACC), regarding a study that claims an association between early exposure to bisphenol a (BPA) and an increased rate of asthma among inner-city children, published in an issue of “Journal of Allergy and Clinical Immunology”:
“The increasing rate of asthma among children is an important public health issue, but there is no scientific consensus on what is causing the increase and this study adds little relevant information to the debate. A large majority of people with asthma have allergies to airborne substances such as trees, grass, weed pollens, mold, animal dander, dust mites, and cockroach particles. The U.S. Environmental Protection Agency (EPA) advises that the most common indoor asthma triggers include secondhand tobacco smoke, dust mites, mold, cockroaches and other pests, and household pets.
“Because of the limited study design based on single samples to monitor exposure, it is difficult to draw any meaningful conclusions from this report. The study design is not capable of establishing a causal relationship between BPA exposures and childhood asthma or wheeze. The statistical associations reported are very modest with weak statistical significance and limited consistency. One association even suggests that BPA exposure reduces the incidence of wheeze.
“The weight of scientific evidence on BPA has been extensively evaluated by government and scientific bodies around the world, which have declared the chemical safe as used in food contact. For example, the EPA has funded recent, robust research conducted by scientists at the government’s Pacific Northwest National Laboratory, Centers for Disease Control and Prevention and Food and Drug Administration. Consistent with previous human and animal studies, the Pacific Northwest study (Teeguarden et al.) indicates that, because of the way BPA is processed in the body, it is very unlikely that BPA could cause health effects at any realistic exposure level.”
