An international research team has found that people whose biological age is higher than their actual age face a sharply increased risk of death and hospitalization, Israel’s Sheba Medical Center has said.
The study, published in Aging and Disease, used routine blood tests and artificial‑intelligence tools to measure biological aging and identify people at higher health risk years before serious illness appears.
Researchers reported that each additional “biological year” beyond a person’s real age raised the risk of death by 15% and the risk of hospitalization by 6%.
Health risks became especially clear when biological age was more than three years above chronological age.
The findings are based on long‑term tracking of nearly 2,600 adults in Israel over more than nine years, with more than 6,700 medical assessments analyzed.
The team said the results could help doctors encourage earlier lifestyle changes, preventive care and closer monitoring for people aging faster than expected.
