Bisphenol A exposure and abnormal glucose tolerance during pregnancy: systematic review and meta-analysis

Exposure to bisphenol A associated with multiple health-related outcomes in humans: An umbrella review of systematic reviews with meta-analyses

Bisphenol A (BPA), a toxic endocrine disruptor, is widely distributed in the environment, and the effects of BPA exposure on human health outcomes are a critical issue. The objective of this study was to perform an umbrella review of published meta-analyses investigating the associations between BPA exposure and human-related health outcomes. The relevant reports were searched from three electronic databases from inception to July 12, 2023 including PubMed, ScienceDirect, and Embase. The reports that were systematic reviews with meta-analyses investigating the associations between BPA exposure and human health outcomes were included in our review. A total of 14 reports were included in our review. Several human health outcomes related to exposure BPA were investigated including maternal prenatal health, infant health, allergic diseases, kidney disease, metabolic syndromes, polycystic ovary syndrome, earlier puberty, inflammation and immune responses, and thyroid function in neonates. Among these health outcomes, BPA exposure was associated with multiple human health outcomes including preterm birth, allergic diseases, kidney disease, polycystic ovarian syndrome, obesity, type 2 diabetes, cardiovascular disease, hypertension, and inflammation and immune responses (C-reactive protein and interleukin-6). These results showed that BPA exposure has seriously affected human health. To protect human health, World Health Organization should develop meaningful regulations on BPA to decrease the environmental contamination.

Association between urinary environmental phenols and the prevalence of cardiovascular diseases in US adults

Environmental phenols, as endocrine disruptors, are used widely in personal care and consumer products. However, few studies have examined the association between phenol exposure, including bisphenol A (BPA), benzophenone-3 (BP-3), and triclosan, and the prevalence of cardiovascular diseases (CVD). This cross-sectional study utilized data from the National Health and Nutrition Examination Survey (2003-2012). Urinary BPA, BP-3, and triclosan were measured with liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). The CVD was defined as a composite of 5 self-reported cardiovascular outcomes, including congestive heart failure, coronary heart disease, angina pectoris, heart attack or stroke. Multivariable logistic regression models were used to examine the association between phenols and the prevalence of CVD. A total of 8164 participants were enrolled, and 740 (9.1%) were diagnosed of CVD. The average levels of BPA, BP-3, and triclosan concentrations were 3.38, 202.63, and 99.27 ng/mL respectively. Per 1-unit increasement in log-transformed urinary BPA was associated with increased risk of CVD after adjusting all covariates (odds ratio [OR] 1.09, 95% confidence interval [CI] 1.01 to 1.18, P < 0.05). Compared with the lowest quartile (< 0.9), the multivariable-adjusted OR was 1.30 (1.03 to 1.65, P < 0.05) in the highest quartile (> 3.8). Restricted spline models confirmed that the association between BPA and the risk of CVD was non-linear (P = 0.045). Only BPA was associated with the risk of CVD, following a J-curve shaped relationship.
