Area of Science:

  • Gerontology
  • Biomedical Science
  • Aging Research

Background:

  • Chronological age is a poor predictor of late-life functional capability.
  • Biomarkers of aging offer a more precise measure of biological aging.
  • Understanding aging is critical for public health and longevity.

Purpose of the Study:

  • To conceptually discuss key aspects of biomarkers of aging.
  • To define the criteria and methods for identifying and assessing aging biomarkers.
  • To highlight the National Institute on Aging's initiative in this research area.

Main Methods:

  • Conceptual discussion and literature review.
  • Defining criteria for valid biomarkers of aging.
  • Outlining measurement and assessment strategies.

Main Results:

  • Biomarkers of aging can predict functional capability independent of disease.
  • Established criteria for evaluating potential biomarkers of aging.
  • Discussed the importance of multivariate approaches for biomarker composites.

Conclusions:

  • Biomarkers of aging are essential for understanding and intervening in the aging process.
  • Rigorous criteria and assessment methods are necessary for biomarker validation.
  • The National Institute on Aging's initiative signifies a growing focus on aging biomarker research.
