How air pollution affects brain development through gut bacteria in children

Pre- and Postnatal Exposure to Air Pollutants and the Gut Microbiome: Implications for Brain Development in Early and Mid-Childhood

NIH-funded research Johns Hopkins University · NIH-11052500

This study is looking at how air pollution during pregnancy and early childhood might affect kids' brain development and behavior, especially by looking at how it changes their gut health, so we can better understand how the environment impacts children's growth.

What this research studies

This research investigates the impact of air pollution exposure during pregnancy and early childhood on brain development and behavior. It focuses on understanding how changes in the gut microbiome, influenced by air pollution, may mediate these effects. By examining both cognitive outcomes and gut health, the study aims to provide a comprehensive view of how environmental factors can affect children's development. The research will involve collecting data from affected populations and analyzing the relationships between air pollution, gut bacteria, and brain function.

Who could benefit from this research

Good fit: Ideal candidates for participation include pregnant women and children under the age of 11 who have been exposed to air pollution.

Not a fit: Patients who are not exposed to air pollution or are over the age of 11 may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved strategies for mitigating the negative effects of air pollution on children's brain development.

How similar studies have performed: Previous studies have shown associations between air pollution and developmental outcomes, but this research is novel in its focus on the gut microbiome as a mediator.
