About the CHIME Study

CHIME, short for “CHIldhoood MicrobiomE“, is a new NIH-funded study focused on learning more about the normal bacteria, or “microbiome”, living in the nose, mouth, and intestine of healthy children. Variations in the microbiome are linked to different childhood diseases, but we do not fully  understand the reasons and what can be done to create a healthier microbiome. This multi-site study will allow researchers to investigate these issues in a way no other study has done before. The information our participants provide will play a vital role in improving our understanding of the microbiome and its relationship to childhood health.


The CHIME study is funded by the ECHO program through the National Institutes of Health  (NIH) and coordinated by the Emergency Medicine Network.
