The Skin Microbiome Better Correlates with Chronological Age than the Gut Microbiome

Researchers here report on their assessment of age-related changes in human skin, oral, and gut microbiomes. They find that the skin microbiome is a better marker of chronological age, which might also be taken as indicating that it is a worse tool for measuring biological age. That adherence to chronological age is, after all, observed despite differences in the pace of aging that exist between individuals. A good biomarker of aging is one that reflects the burden of damage and consequent mortality, and therefore will measure a higher age in someone more burdened, rather than only correlating with the chronological progression of time.

Human gut microbiomes are known to change with age, yet the relative value of human microbiomes across the body as predictors of age, and prediction robustness across populations is unknown. In this s…
