Quantification of biological aging in young adults.

Abstract

Antiaging therapies show promise in model organism research. Translation to humans is needed to address the challenges of an aging global population. Interventions to slow human aging will need to be applied to still-young individuals. However, most human aging research examines older adults, many with chronic disease. As a result, little is known about aging in young humans. We studied aging in 954 young humans, the Dunedin Study birth cohort, tracking multiple biomarkers across three time points spanning their third and fourth decades of life. We developed and validated two methods by which aging can be measured in young adults, one cross-sectional and one longitudinal. Our longitudinal measure allows quantification of the pace of coordinated physiological deterioration across multiple organ systems (e.g., pulmonary, periodontal, cardiovascular, renal, hepatic, and immune function). We applied these methods to assess biological aging in young humans who had not yet developed age-related diseases. Young individuals of the same chronological age varied in their "biological aging" (declining integrity of multiple organ systems). Already, before midlife, individuals who were aging more rapidly were less physically able, showed cognitive decline and brain aging, self-reported worse health, and looked older. Measured biological aging in young adults can be used to identify causes of aging and evaluate rejuvenation therapies.

Terrie E. Moffitt

Nannerl O. Keohane University Distinguished Professor

Terrie E. Moffitt, Ph.D., is the Nannerl O. Keohane University Professor of Psychology at Duke University, and Professor of Social Development at King’s College London. Her expertise is in the areas of longitudinal methods, developmental theory, mental disorders and antisocial behaviors, neuropsychology, and genomics in behavioral science. She is currently uncovering the consequences of a lifetime of mental and behavioral disorder on processes of aging. She is the Associate Director of the Dunedin Longitudinal Study, which follows a 1972 birth cohort in New Zealand. She also co-founded the Environmental Risk Longitudinal Twin Study (E-Risk), which follows a 1994 birth cohort in the UK. Dr. Moffitt also is a licensed clinical psychologist, with specialization in neuropsychological assessment. She collaborates with criminologists, economists, geneticists, epidemiologists, sociologists, demographers, gerontologists, statisticians, neuroscientists, medical scientists, opthalmologists, and dentists. Dr. Moffitt is a fellow of the National Academy of Medicine and  the American Academy of Arts and Sciences , as well as the British Academy, Academy of Medical Sciences (UK), Academia Europa, Association of Psychological Science, and the American Society of Criminology. She holds honorary doctorates from the Katholieke Universiteit Leuven, Belgium, and Universitat Basel, Switzerland. For her research, Dr. Moffitt has received both the American Psychological Association's Early Career Contribution Award and Distinguished Career Award. Dr. Moffitt was also awarded a Royal Society-Wolfson Merit Award, the Klaus-Grawe Prize, and was a recipient of the Stockholm Prize in Criminology, NARSAD Ruane Prize, the Klaus J. Jacobs Research Prize, and in 2022 the Grawemeyer Prize. Her service includes serving as chair of the Board on Behavioral, Cognitive, and Sensory Science at NASEM, Chair of the NIA Data Monitoring Committee for the Health and Retirement Study, and Chair of the Jury for the Klaus J. Jacobs Prize in Switzerland. Dr. Moffitt attended the University of North Carolina at Chapel Hill for her undergraduate degree in psychology. She continued her training in psychology at the University of Southern California, receiving an M.A. in experimental animal behavior, and a Ph.D. in clinical psychology. She also completed postdoctoral training in geriatrics and neuropsychology at the University of California Los Angeles Neuropsychiatric Institute. In her spare time, she works on her poison-ivy farm in North Carolina.
