Hypothesis

Can biological age metrics reliably predict aging processes in a clinical cohort?

Conclusion

Klemera-Doubal Method and PhenoAge are validated as reliable biological age metrics that can be used in clinical settings to assess aging and predict health outcomes.

Supporting Evidence

  • Klemera-Doubal Method and PhenoAge showed strong correlations with chronological age.
  • Homeostatic Dysregulation exhibited minimal correlation with chronological age.
  • Several significant predictors of biological age were identified using LASSO regression models.

Takeaway

This study looked at how well certain age measurements can tell us about health in older people, and found that some methods work really well.

Methodology

A 12-week, randomized, parallel group, double-blind, placebo-controlled pilot study.

Participant Demographics

23 participants, 14 male and 9 female, aged 76 years on average, with a range of 65 to 90 years.
