Metagenomic characterization of the maternal prenatal gastrointestinal microbiome by pregravid BMI

Obesity (Silver Spring)Published Cross-sectional study

Authors' conclusion

Our analysis suggests that there are differences in microbial composition and function between BMI groups. Future research should consider how these changes contribute to specific clinical outcomes during pregnancy.

Study context

Population
Pregnant women; maternal prenatal gastrointestinal microbiome by pregravid BMI
Participants
105 biospecimens
Exposure
Pregravid BMI groups: obesity or overweight vs normal weight
Outcome
Gastrointestinal microbiome composition and function
Methodological detailsshotgun metagenomics
  • Shotgun metagenomics

Main finding

As reported in the abstract

  • Enrichment in Firmicutes across all pregravid BMI groups
  • Obesity or overweight: enrichment in Bifidobacterium bifidum and B. adolescentis
  • BMI > 25 kg/m²: higher abundance of microbiota supporting biotin synthesis and regulating lower GI epithelial cells
  • Obesity or overweight vs Normal weight: P = 0.02

Observational data: associations, not effects.
