About the Presentation

In this talk I’ll present a method to estimate biological age (BA) using a set of biomarkers of health. I applied the proposed method to data from the US National Health and Nutrition Examination Survey 1988-1994 and compare results with three of the most commonly used methods in the literature (principal components, linear regression, and a method proposed by Klemera-Doubal). We pursue this analysis further by (i) using our BA estimates as predictors of mortality using the NHANES mortality follow-up, and (ii) assessing how differences between chronological age and biological age link with an individual's risk of death. There are two main conclusions. If researchers are interested in producing BA values that are interpretable, then either Klemera-Doubal’s or any of our proposed methods will suffice. However, if the interest is in understanding the underlying aging process associated with BA, our proposed method would be more appropriate.

About the Speaker

Hiram Beltran-Sanchez

Dr. Beltrán-Sánchez is Associate Professor in the Department of Community Health Science at the Fielding School of Public Health and at the California Center for Population Research, both at UCLA. His main areas of research include the study of health patterns and trends in low- and middle-income countries including issues about compression of morbidity; links between early life experiences and late life outcomes; as well as on biomarker data to study physiological patterns of health and their link with sociodemographic factors.
