What this research studies

You would be asked to join a project enrolling about 200 children with asthma and 100 without asthma from Richmond, CA. We will collect blood and airway samples (nasal swabs and sputum) when children are stable and again during acute breathing episodes over one year, and combine these with information about air pollution, stress, and clinical symptoms. Scientists will run a wide range of lab tests (multi-omics) on the samples to find biological patterns tied to exposures and asthma outcomes. The aim is to understand why asthma differs between children and which exposures lead to worse symptoms in this community.

Who could benefit from this research

Good fit: Children up to about 11 years old who live in Richmond, CA, both with asthma and without asthma, especially those from Latine and other historically marginalized communities.

Not a fit: Adults, people living outside the Richmond area, or those unable or unwilling to provide blood or airway samples are unlikely to participate or benefit directly from this project.

Why it matters

Potential benefit: If successful, this work could lead to more personalized care, better prevention of attacks, and actions to reduce harmful exposures in communities with high asthma burden.

How similar studies have performed: Previous studies have linked pollution and stress to asthma, but combining airway and blood multi-omics with detailed exposure data in underserved children is a relatively new and promising approach.
