Implication

Randomized trial examines metabolic changes associated with PBDE exposure and preterm birth in African American women, suggesting health risks from environmental pollutants.

Key Points

To explore the relationship between maternal PBDE levels and metabolic profiles related to preterm birth.
Examined serum PBDE levels and metabolomic profiles of 177 pregnant women aged 18–40 years
Used chromatography-tandem mass spectrometry to quantify PBDE levels in maternal serum and high-resolution mass spectrometry for metabolomic profiling
Conducted metabolome-wide association studies with generalized linear models to identify links between PBDE levels and preterm birth.
46 (26%) of participants experienced preterm birth
Identified 26 metabolites associated with PBDE levels and/or preterm birth, linked to disruptions in thiamine-dependent pathways and inflammation
Findings indicate PBDE exposure may affect oxidative stress and energy metabolism, contributing to preterm birth risk.
