Bisphenol A and adverse pregnancy outcomes: a systematic review of the literature

Abstract

Purpose: Bisphenol A is a chemical compound related to adverse maternal and neonatal outcomes. The purpose of the present systematic review is to summarize the current knowledge in the field.

Materials and methods: We systematically searched the Medline (1966–2017), Scopus (2004–2017), Clinicaltrials.gov (2008–2017), Cochrane Central Register of Controlled Trials CENTRAL (1999–2017) databases.

Results: Thirty-five studies were included in the present systematic review. According to our findings, BPA has a direct negative impact on maternal, fetal, and neonatal outcomes, including birthweight, rates of preterm birth, developmental defects, and recurrent miscarriage. Data in the field of preeclampsia and gestational diabetes mellitus remain inconclusive because current research is very limited.

Conclusions: BPA exposure during pregnancy can result in significant antenatal pathology; hence, occupational exposure should be at least discouraged during this period. However, cross-sectional studies in the field that would assess the levels of exposure at timely intervals are still lacking, therefore, the actual impact of BPA remains unclear.
