Insights
Maternal exposure to Per and Poly-Fluoroalkyl Substances (PFAS) during pregnancy is linked to childhood obesity. PFAS disrupt placental health and child development, impacting body mass index and potentially leading to long-term health issues.
Area of Science:
- Environmental Health
- Endocrinology
- Developmental Pediatrics
Background:
- Maternal exposure to Per and Poly-Fluoroalkyl Substances (PFAS) is a growing concern for child development.
- PFAS exposure is associated with increased adiposity and potential health risks in children.
- The precise mechanisms linking maternal PFAS levels to childhood obesity require further elucidation.
Purpose of the Study:
- To review the effects of Per and Poly-Fluoroalkyl Substances (PFAS) exposure on overweight and obese children.
- To explore the underlying mechanisms of PFAS action in pregnant women and their offspring.
- To synthesize current knowledge on the relationship between maternal PFAS concentration and child obesity.
Main Methods:
- A comprehensive literature review was performed using major scientific databases.
- The review focused on studies investigating PFAS effects on maternal and child health, including neurological outcomes.
- Analysis included in vitro and in vivo studies, as well as human epidemiological data.
Main Results:
- PFAS exposure disrupts placental health and child growth, negatively impacting body mass index.
- In vitro and in vivo studies demonstrate PFAS-induced adipogenesis and weight gain via PPAR-γ and ER-α activation.
- Maternal serum PFAS concentrations show a positive correlation with adverse child health outcomes.
Conclusions:
- PFAS readily cross the placenta, posing a risk to fetal development and long-term child health.
- Disruption of placental homeostasis by PFAS can lead to adverse pregnancy and child health outcomes.
- Further research is essential to fully understand the complex implications of PFAS exposure for maternal and child well-being.
Background:
Childhood obesity is significantly influenced by maternal exposure to Per and Poly-Fluoroalkyl Substances (PFAS) during pregnancy. PFAS exposure occurs through the Peroxisome Proliferator-Activated Receptor (PPAR-γ) receptor, leading to increased fat deposition and profound health effects in child growth and development. Despite ongoing investigations, the relationship between maternal serum PFAS concentration and child obesity requires further exploration.
Objective:
This study aimed to review the possible effects of Per and poly-fluoroalkyl substances exposure and their mechanism in overweight/obese children from pregnant ladies.
Methods:
A detailed literature survey was conducted using online databases, including Science Direct, Google Scholar, Scopus, Cochrane, and PubMed. The study focused on the diverse effects of PFAS on maternal and child health, with particular emphasis on neurological complications.
Results:
Child growth development depends upon breastfeeding and placenta health, which is disrupted by PFAS exposure, ultimately destroying the body mass index of the child. Neurotoxicity testing utilized the SH-SY5Y human-derived cell line as an in vitro model, revealing PFAS-induced increases in adipocyte number, reduced cell size, altered lipid conglomeration, increased adiposity, and changes in liver function. in vivo studies in mice and human cell lines indicated PPAR-γ and ER-α activation, leading to adiposity and weight gain through Estrogen signaling and Lipid metabolism. PFAS concentrations positively correlated in maternal sera, analyzed by liquid chromatography/quadrupole mass spectrometry.
Conclusion:
PFAS, with a long half-life of 3.5-8.5 years, is commonly found in the serum of pregnant women, crossing the placenta barrier. This exposure disrupts placental homeostasis, negatively impacting mechanisms of action and potentially leading to deterioration in pregnancy and child health. Further research is needed to comprehensively understand the complex interplay between PFAS exposure and its implications for maternal and child well-being.
