What is the Origin of Biological Age Estimates?

The foundation of this concept lies in gerontology and epigenetics, with the development of epigenetic clocks, such as the Horvath and Hannum clocks, which quantify DNA methylation patterns. Other methods incorporate physiological markers like telomere length, metabolic panel data, and inflammatory markers. The goal is to provide a quantitative measure of the cumulative biological damage or preservation.

What is the Mechanism of Biological Age Estimates?

The estimation mechanism involves sophisticated algorithms that process a panel of inputs, most notably the methylation status of specific CpG sites across the genome. This epigenetic information reflects the long-term interaction between genetics, lifestyle, and environment, including hormonal exposures and metabolic health. Clinically, a lower biological age relative to chronological age indicates successful health and longevity optimization strategies.

Biological Age Estimates

Meaning

Biological age estimates are calculations derived from analyzing specific molecular and physiological biomarkers to determine the functional age of an individual’s tissues and organ systems, which often deviates from their chronological age. These estimates provide a clinically relevant assessment of the rate of aging and the overall systemic health burden. They serve as a powerful prognostic tool for longevity and chronic disease risk stratification.
