"Aging Tests Yield Varying Results" - Science Newsline. 11/16/2017.
In 2015, Duke's Daniel Belsky and colleagues used data from the life-long Dunedin, NZ study to develop 18 measures of biological aging for participants who were age 38 at the time. Their results were published in PNAS. In an expanded study published this week in AJE, Belsky et al. have found some disagreement about whether these measures all point in the same direction. Belsky says having measures of biological aging is important: “People age at different rates and geriatric medicine needs a way to measure that." But when measuring many different physiological indicators - from genes to blood markers to balance and grip strength - “you see a lot of disagreement.”
