Temporal Changes in the Gut Microbiota Before and After Migrating to High Altitude
Temporal Changes in Gut Microbiota of Healthy Adults Before and After Migrating to High Altitude: a Longitudinal Study
This prospective observational cohort study aims to learn about temporal changes in the gut microbiota before and after migrating to high altitudes in healthy participants. The main questions it aims to answer are:
- changes in the gut microbiome before and after migrating to high altitude.
- Do the migrants tend to share similar gut microbiota characteristics with the residents? Participants will detect 16S ribosomal RNA profiles from stool samples. Researchers will compare the residents with the migrants to see if gut microbiota characteristics are similar.

The study group consists of five volunteers who originally lived in a plain area.
They will be living in a high-altitude region for one year.
|
no intervention
