Authors' own conclusions state "We acknowledge limitations of our study."
WASHINGTON (Aug. 22, 2013)
The American Chemistry Council (ACC) issued the following statement in response to an article in Pediatrics by Donna S. Eng, M.D., New York University, et al. The following statement can be attributed to Steven G. Hentges, Ph. D., of the Polycarbonate/BPA Global Group of ACC:
"Attempts to link our national obesity problem to minute exposures to chemicals found in common, everyday products are a distraction from the real efforts underway to address this important national health issue. As with other studies of this nature, due to the inherent, fundamental limitations, it is incapable of establishing any meaningful connection between BPA and obesity, or any other chronic disease.
"It is well-established in scientific literature that BPA is rapidly eliminated from the body such that single urine biomonitoring samples indicate only very recent exposure. Such samples provide essentially no information about BPA exposure in previous months or years when the chronic disease in these subjects would have developed. The authors themselves state: 'We also acknowledge limitations of our study. We used a cross sectional study design; therefore, reverse causality cannot be excluded.'
"More relevant to actual, real-world safety is the recent, robust research funded by the Environmental Protection Agency and conducted by scientists at the government's Pacific Northwest National Laboratory, Centers for Disease Control and Prevention and the U.S. 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. Furthermore, regulators from Europe to Japan to the United States have recently reviewed hundreds of studies on BPA and repeatedly supported the continued safe use of BPA.
"It is also relevant to note that dozens of studies have monitored the body weight of laboratory animals exposed to BPA. These studies found no consistent effect on body weight, indicating that BPA exposure is not likely to cause obesity."
