Young kids who were exposed to Bisphenol A (BPA) before birth are more likely than others to have a wheeze before age five, according to a new study that found no connection to BPA exposure after birth. The results suggest a relationship between the exposure to BPA during early pregnancy and the likelihood of developing early wheeze, said Dr. Randall M. Goldblum, director of the Child Health Research Center Lab and Children’s Asthma Program at UTMB. He was not involved in the new study. “It is difficult to say if this is the cause, because the development of asthma is complex and includes genetic predisposition as well as environmental exposures like the one documented,” he told Reuters Health by email. If children get over their early wheeze by age five there is a good chance they will not have it again later in life, he noted. “Some of the children will have asthma and they will continue to have wheezing episodes,” Goldblum’s colleague Dr. Terumi Midoro-Horiuti added.
