A study of 454 infants hospitalized at two New Orleans hospitals found that babies born to mothers from high-pollution areas of southeast Louisiana had 4.3 times the odds of severe congenital heart defects compared with babies from low-pollution areas. The study reports an association; it does not establish that pollution caused the defects.

Why it matters

The findings concern families and communities in southeast Louisiana and may inform local public-health research and environmental oversight. The study’s limited sample of hospitalized infants means it does not by itself establish risk for all births in the region.

What happens next

The study was published in Environmental Health, according to The Guardian. The article does not identify further research or an official response.
