# DunedinPACE

DunedinPACE (Pace of Aging Calculated from the Epigenome) is an epigenetic clock published in 2022 by Belsky and colleagues. Unlike most clocks, it estimates your rate of biological aging, not a static age. It was trained in the Dunedin 1972-1973 birth cohort, on long-term change across 19 organ-system biomarkers. That was then translated into a DNA-methylation score using 173 CpGs. The score is calibrated so that 1 means the cohort-average pace: one year of biological aging per calendar year. A value above 1 means you are aging faster than average. DunedinPACE shows good test-retest reliability, and it predicts illness and death.
