How early-life microbes affect childhood asthma

Microbiome Influences on Asthma-Related Outcomes in Early Life

NIH-funded research University of Arizona · NIH-11363731

This project looks at whether the microbes living in babies’ noses and guts change the chance and severity of asthma in young children.

What this research studies

You or your child would be followed during early life and researchers would collect samples such as stool and nasal swabs along with health information. The team would compare microbial patterns with wheezing, allergy test results, lung function, and asthma diagnoses as children grow. Laboratory tests on those samples may be used to understand how microbes influence immune responses linked to asthma. Some parts of the program may use lab models to test biological mechanisms suggested by the human data.

Who could benefit from this research

Good fit: Ideal candidates would be infants or young children, particularly those with a family history of asthma or early breathing problems.

Not a fit: Adults with long-standing asthma or people without early-life respiratory concerns are less likely to benefit directly from this work.

Why it matters

Potential benefit: If successful, this work could point to new ways to prevent or reduce childhood asthma by altering microbes or timing of exposures early in life.

How similar studies have performed: Previous studies have linked early-life microbial patterns to later asthma risk, but converting those findings into proven prevention or treatments is still experimental.
