Traffic pollution in pregnancy and its effects on the placenta and child thinking

Prenatal Traffic-Related Air Pollutants, Placental Epitranscriptomics, and Child Cognition

NIH-funded research Columbia University Health Sciences · NIH-11251949

This project looks at whether traffic-related air pollution during pregnancy changes chemical signals in the placenta and links to children's thinking and attention.

What this research studies

The team measures how much traffic-related air pollution pregnant people were exposed to during pregnancy. They analyze placentas for RNA chemical marks called m6A and the proteins that add, read, or remove those marks. Researchers follow children's thinking and attention as they grow, linking placenta changes to cognitive outcomes at early ages. The work uses human placental samples and child follow-up to connect prenatal exposure with later development.

Who could benefit from this research

Good fit: Ideal participants would be pregnant people or families willing to provide placenta samples at birth and join follow-up visits for their young children, especially those living near traffic sources.

Not a fit: People who are not pregnant, do not have young children, or who cannot provide placenta samples or participate in follow-up would not directly benefit from joining this work.

Why it matters

Potential benefit: If successful, this work could reveal how prenatal traffic pollution harms brain development and point to ways to prevent or reduce developmental problems in affected children.

How similar studies have performed: Previous animal and human studies have linked prenatal traffic pollution to neurodevelopmental problems, but examining placental m6A RNA changes as a mechanism is a new approach.
