In COPSAC 2010 children, gut microbiota maturation is rapid from 1 week to 4 years and then slows through 6 years, with microbial age predicted from community composition.
- Why it matters: Early-life microbiota development is linked to long-term health, but the timing of maturation and how exposures shape community stability are not well defined.
- What they did: Using 16S rRNA gene sequencing of 2,689 fecal samples from 695 children (1 week–6 years), the study modeled microbial age with a random forest and defined high- vs low-maturity states.
- The result: High-maturity microbiota shows greater alpha diversity, lower beta-dispersion, and maturity-associated network structures, and 1-year composition predicts 4-year maturity with modest, non-random performance.
