Antibiotic Exposure During Pregnancy Affects Infant Gut Microbiota

Recruiting
Conditions
Antibiotics Affecting Newborn Gut Microbiota
Interventions
Other: antibiotic treatment
Registration Number
NCT06479941
Lead Sponsor
Peking University People's Hospital
Brief Summary

Based on a prospective birth cohort, the investigators will collect biological samples from participants including pregnant women and newborns, to measure the gut microbial diversity and metabolites of newborns. These results systematically evaluate the effects of antibiotic exposure on the structure and function of gut microbiota. The project can reveal the effects of antibiotic exposure on the growth and development of gut microbiota in early life.
