Investigating how breastfeeding and early-life microbiomes affect respiratory health in children

Official title: BREATH - Breastfeeding, Early-life Microbiome and Respiratory Health Study

Funded at New York University School of Medicine · NIH-10975578 · Data updated 2026-11-12

This study is looking at how breastfeeding affects the good bacteria in babies' tummies and noses, and how that might relate to breathing problems like asthma and allergies as they grow up, so we can better understand how to keep kids healthy.

Who could benefit from this research

Could help

Ideal candidates for this research include infants and young children, particularly those with a family history of asthma or allergies.

Less likely to help

Patients who are older than 11 years or those who were not breastfed may not receive direct benefits from this research.

What this research studies

This research explores the relationship between breastfeeding, the development of the microbiome in infants, and respiratory health outcomes in children. By utilizing large birth cohorts and advanced algorithms, the study aims to identify how breastfeeding influences the gut and nasal microbiomes, which are linked to conditions like asthma and allergies. The research will analyze over 14,000 samples to uncover the mechanisms that connect these factors and their impact on childhood respiratory diseases.

Why it matters

Potential benefit: If successful, this research could lead to new strategies for preventing respiratory diseases in children by understanding the role of breastfeeding and microbiome development.

How similar studies have gone: Previous studies have shown promising links between the microbiome and respiratory health, but this research aims to provide more definitive insights and is considered a novel approach.
