Multi-Compartment Aging Clocks Reveal Hidden Patterns of Biological vs Chronological Age
Researchers analyzed proteins and metabolites across blood, urine, and skeletal muscle in 101 healthy adults aged 22-92 to create biological aging scores. These multi-compartment predictors revealed that different body systems age at varying rates, with some individuals showing accelerated or decelerated aging compared to their chronological age. The aging scores correlated with inflammation, iron deficiency, muscle mass decline, and kidney/liver function changes.
