Gut microbial signatures in type 2 diabetes are highly associated with geographic region, diet habits and common comorbidities: Insights from a bioinformatics analysis of Chinese population
Authors' conclusion
Our study highlights the potential role of gut microbiota in T2D pathogenesis and provides clues that specific microbial signatures may serve as biomarkers for T2D diagnosis and personalized management in Chinese populations. The findings indicate that modifiable factors including dietary factors, living regions and common comorbidities may influence the gut microbiota, thereby affecting T2D development.

Observational data: associations, not effects.
Further findings
T2D classification
- Random forest models incorporating microbial signatures and covariates improved accuracy of T2D classification
Host factors and specific microbial signatures
- Geographic region, diet habits (staple food sources, coffee drinking) and common comorbidities such as hypertension were associated with specific microbial signatures
