Summary

This study plans to collect 106,667 fecal samples from Chinese infants and children under 6 years old, with multi-dimensional stratification based on geographic location, mode of delivery, antibiotic exposure, and developmental stage. Fecal gut microbiota will be profiled to construct a gut microbiome atlas, establish quantitative analytical models linking geographic regions, physiological phenotypes and microbial signatures, and identify key microbial biomarkers associated with core healthy phenotypes.

Conditions

  • Fecal Gut Microbiota

Interventions

OTHER

Fecal sample collection and gut microbiome profiling

This study is purely observational with no therapeutic or invasive clinical interventions implemented. We only collect non-invasive fecal specimens from enrolled healthy infants and children aged 0-6 years across China, perform microbial genome sequencing and microbial isolation culture to analyze gut microbiota characteristics, and construct a national pediatric gut microbiome atlas. No drugs, medical devices or clinical treatment adjustments are given to participants throughout the research.
