Babies more likely to have heart defects from Louisiana’s areas with industrial pollution, study finds

Compared to infants in the state's low-pollution areas, the odds were 4.3 times higher for babies from toxic hotspots

A study looking at babies hospitalized in New Orleans found that babies born to mothers from neighborhoods in south-east Louisiana with high levels of industrial pollution were four times more likely to suffer from severe congenital heart defects.

Published last week, the study in the Environmental Health journal looked at medical records for 454 infants hospitalized at the two major Louisiana hospitals that can provide surgery for heart defects in babies. Researchers traced back where the mothers of these infants lived, examining the levels of industrial toxic pollution in their communities using the US Environmental Protection Agency's risk-screening database. Compared to infants from low-pollution areas in the region, the odds of congenital heart defects were 4.3 times higher for infants from toxic hotspots, and 3.1 times higher for infants from places with intermediate levels of pollution.
