AIIMS Study Details How Urban Air Pollution Affects Placental Function and Fetal Growth
A study by AIIMS Delhi reveals that fine particulate matter (PM2.5) from urban air pollution can cross the placental barrier, triggering inflammation and suppressing IGFBP3, a protein vital for placental function and fetal growth. Analysis of data from Delhi and Jharkhand linked higher pollution exposure to low birth weight and pregnancy complications like preeclampsia. The research combines human and animal studies to detail molecular pathways by which pollution impairs nutrient exchange and blood vessel development in the placenta.
