While the FDA isn't willing to fully commit on the safety of endocrine-disrupting chemical bisphenol A (BPA)--its promised report is months overdue--researchers from Peninsula College of Medicine in Britain took on the task. They looked at data from the 2003-2004 US National Health and Nutrition Examination Survey (NHANES) which included urinary BPA levels for the first time, and found that 25% of the population with the highest levels of BPA were more than twice as likely to report having heart disease or diabetes compared to the 25% with the lowest levels of BPA.They thought that maybe it was a statistical fluke. When the 2005-2006 NHANES came out, the same team did the same analysis on a different population sample, and they got the same results.
According to an article in the Toronto Globe and Mail, the new research shows that 60-year-old American males with the highest amounts of bisphenol A in their urine had about a 45 per cent greater risk of cardiovascular disease than men the same age with lower exposures.The researchers performed rigorous calculations to ensure that they isolated the effect of bisphenol A and weren’t getting correlations with other factors. Dr. Melzer, who led the study, believes the study underestimates the effect of BPA due to the relatively small sample size.
Following the release of the report, the FDA announced it has "some concern" about the effects of BPA on fetuses and infants.
