Can PFAS exposure in umbilical cord blood increase preterm birth risk?
Some Concern
What's actually in it
By the time a baby is born, PFAS from the mother's nonstick cookware, food packaging, and water have already crossed the placenta. These chemicals are detectable in umbilical cord blood, proving they reach the baby before birth. PFAS disrupt metabolic pathways the baby needs for healthy development.
What the research says
A 2026 multicenter case-control study in Environ Sci Technol measured PFAS and metabolites in umbilical cord blood and compared preterm births to full-term births. The researchers found that higher PFAS levels and specific metabolic disruptions were linked to preterm birth. Key metabolic intermediates mediated the connection between PFAS exposure and early delivery.
Preterm babies face higher risks of breathing problems, feeding difficulties, and developmental delays. These findings suggest PFAS may be contributing to the persistent problem of preterm birth.
Before and during pregnancy, filter your water, avoid nonstick cookware, and skip stain-resistant treatments on furniture and clothing.
