NIH study explores pollution exposure and birth outcomes in pregnant women living in historically redlined neighborhoods

Residence in redlined census tracts during pregnancy was associated with higher exposure to PM2.5 and lower birth weight in a recent study funded by the Environmental influences on Child Health Outcomes (ECHO) Program.

Additionally, living in ungraded census tracts was linked to elevated PM2.5 exposure, lower birth weight, and increased odds of low birth weight. These findings suggest that factors beyond redlining may contribute to ongoing inequalities in health outcomes. Further research is needed to explore these dynamics and their implications for maternal and infant health.
