Relationship between urinary bisphenol a levels and cardiovascular diseases in the U.S. adult population. - GreenMedInfo Summary

BACKGROUND: Emerging evidence has identified cardiovascular system as a potential target of Bisphenol A (BPA). Although a few studies have revealed the relationship between BPA and the risk of several cardiovascular diseases (CVD) outcomes and CVD risk factors, no published studies have investigated the link between urinary BPA and the risk of stroke.

METHODS: Data were derived from the United States National Health and Nutrition Examination Surveys (NHANES), with a representative sample aged≥20 years (n = 9139) from 2003 to 2014. We performed multivariable logistic regression model to estimate associations between quartiles and natural logarithm transformed urinary BPA concentrations and five specific CVD outcomes and total CVD.

RESULTS: In quartile analysis, highest level of urinary BPA was associated with increased prevalence of myocardial infarction (MI) (OR = 1.73, 95% CI = 1.11-2.69) and stroke (OR = 1.61, 95% CI = 1.09-2.36), when compared with those at the lowest quartile. Per unit (μg/g creatinine) increment in ln-transformed BPA concentration was shown to be significantly associated with 19%, 19%, 25%, 29%, 20%, and 16% increased odds ratios of prevalence of congestive heart failure, coronary heart disease (CHD), angina pectoris, MI, stroke and total CVD among total participants, respectively. Similar associations were found in males rather than in females.

CONCLUSION: We provided the premier evidence of positive relationship between urinary BPA concentration and stroke in U.S.

POPULATION: Urinary BPA levels were also positively correlated with congestive heart failure, CHD, angina pectoris, MI, as well as total CVD. These associations were more evident in males. Well-coordinated and prospective studies are warranted to gain the human effects of BPA on CVD.
