AI Article Synopsis
- This study aimed to clarify the inconsistent findings on prenatal BPA exposure and birth outcomes by reviewing existing research.
- Six studies involving 3004 participants were analyzed, revealing a significant positive association between BPA exposure and increased birth weight, but no link to birth length, head circumference, or gestational age.
- The authors concluded that while BPA is linked to higher birth weight, more research is necessary to explore the effects on fetal development during sensitive periods and potential differences based on gender.
Article Abstract
Background: Previous studies investigated the relation of prenatal exposure to bisphenol A (BPA) and birth outcomes, but these results were inconsistent. The aim of this study was to investigate the relation of prenatal exposure to BPA and birth outcomes, provide comprehensive results based on current studies.
Methods: The PubMed, Cochrane databases, and Web of Science databases were searched systematically by two researchers respectively from their inceptions to Oct. 2018, using the following keywords "bisphenol A, birth weight, birth length, head circumference, gestational age, birth outcomes". We extracted β coefficient and 95% confidence interval (CI) or β coefficient and standard deviation (SD) from included study. The subgroup analysis was performed to evaluate the potential heterogeneity between studies. We conducted sensitivity analysis by excluding the each individual study to assess the results whether were stable. Finally, the publication bias was performed by accumulative forest plot.
Results: Seven studies with 3004 participants met the inclusion criteria. BPA had significant positively association with birth weight (β = 21.92, 95%CI: 1.50-42.35, P = .04). No significant associations were found between BPA and birth length, head circumference and gestational age (All of P > .05).
Conclusion: This meta-analysis demonstrated that the BPA was positively associated with birth weight. Therefore, further studies are needed to investigate the critical sensitive period of influencing fetal development and to investigate the difference on gender.

Background: Preeclampsia is a severe, multisystem complication that affects 2%-5% of pregnancies, and is a leading cause of fetal and maternal morbidity and mortality worldwide. Preeclampsia may have devastating results on maternal health and may affect offspring's immediate and long-term health. Previous studies have examined the impact of maternal preeclampsia on the long-term health outcomes of offspring, many of these studies have been limited by confounding factors that could bias the results.

This study is aimed at evaluating the neurotoxic effects of chronic exposure of sodium fluoride (NaF) in developmental stages in rat using prenatal models. NaF (100 ppm, orally) dosing via drinking water was given to pregnant rats in disease group. In the treatment groups, Metformin & Dehydrozingerone (DHZ) (200 mg/kg) were administered orally along with NaF, and the dosing was continued throughout the gestation and lactation periods to the pups until the end of experiment.

Early language is shaped by parent-child interactions and has been examined in relation to maternal psychopathology and parenting stress. Minimal work has examined the relation between maternal emotion dysregulation and toddler vocabulary development. This longitudinal study examined associations between maternal emotion dysregulation prenatally, maternal everyday stress at 7 months postpartum, and toddler vocabulary at 18 months.

Background: Early child development sets the course for optimal outcomes across life. Increasing numbers of children worldwide are exposed to opioids in pregnancy and frequently live in environments associated with adverse developmental outcomes. Although multiple systematic reviews have been published in this area, they use different exposures and different types of outcomes.
