Bisphenol A (BPA) exposure may be linked to an increased risk of all-cause mortality, JAMA Network Open reported referring to the study.

Wei Bao, MD, of the University of Iowa College of Public Health, and his colleagues conducted a study of 3,800 people over 20 who participated in the US National Health and Nutrition Examination Survey 2003-2008. All of these people provided urine samples to measure BPA levels.

After examining all the data obtained, the scientists recorded 344 deaths over 36,514 person-years of observation, including 71 deaths from cardiovascular diseases and 75 deaths from cancer. That being said, the risk of death was higher in participants with higher urinary BPA levels.

The observed link between BPA exposure and cardiovascular mortality requires further study, according to the study authors. Further research is also needed to replicate the findings of this study in other populations and to identify the underlying mechanisms.
