A study of 1,813 older women suggests that the accelerated biological aging of the body is associated with lower odds of living to be 90 years old.
The epigenetic age acceleration could be used as a biomarker for healthy longevity and to estimate functional and cognitive aging.
If an individual’s epigenetic age is greater than their chronological age, the person is undergoing epigenetic age acceleration, associated with higher risk of age-related diseases.
“Healthspan ... who will live to be 90 years and older will quadruple from 1.9 million in 2016 to 7.6 million in 2050 in the United States alone,” said principal investigator Andrea LaCroix.
Epigenetic age acceleration can be used to estimate the risk of an individual not attaining healthy longevity and poor health outcomes among older populations.
