Researchers from the Peninsula Medical School at Exeter and the University of Exeter say they have found evidence of a link between bisphenol A exposure and cardiovascular disease.
The study used data from research on the U.S. population through National Health and Nutrition Examination Surveys, a research program of the National Center for Health Statistics. The team's original paper in 2008 was the first to associate BPA and heart disease. The authors said the new data confirms those earlier findings.
Tamara Galloway, ecotoxicology professor at the University of Exeter and the paper's senior author, said: We now need to investigate what causes these health risk associations in more detail and to clarify whether they are caused by BPA itself or by some other factor linked to BPA exposure.
She said that although the risks of BPA may be small, they are relevant to large numbers of people.
This information ... provides a great opportunity for intervention to reduce the risks, she said.
The Arlington, Va.-based American Chemistry Council said in a statement that the study does not establish a cause-and-effect relationship between BPA exposure and heart disease.
Studies of this type ... can provide helpful information on where to focus future research, [but] by themselves they cannot and should not be used to demonstrate that a particular chemical can cause a particular effect, said Steven Hentges, who heads ACC's Polycarbonate/BPA global group.
The results of the study have been published by the online journal PlosOne.org.
