Epigenetic age acceleration (DNA methylation age minus chronological age) is positively associated with clinical frailty, whereas telomere length shows no significant association with either epigenetic age acceleration or frailty.

Use epigenetic age acceleration as a biomarker for overall health status rather than a deterministic prediction of your lifespan. Since it correlates with frailty, focusing on building physical resilience (strength, balance, activity) and managing chronic conditions may help align your epigenetic age with your chronological age. Do not rely on telomere length as a primary health indicator, as this study found no link to frailty.

ModerateQualifiesMEDIUM confidence
However, there was an association of DNA methylation age acceleration with a comprehensive frailty measure, such that the accumulated deficits significantly increased with increasing age acceleration... No correlation of epigenetic age acceleration with telomere length was found in our study (p = 0.63).

Why this rating

Large sample size (n=1820) and robust frailty index, but cross-sectional design prevents causal inference.
