Arterial stiffness increases sarcopenia risk partly through accelerated biological aging
A large UK Biobank study finds vascular stiffness links to muscle loss, with accelerated biological age explaining part of the risk in non-frail adults.

In a prospective cohort of 32,451 UK Biobank participants, researchers evaluated how arterial stiffness influences the development of muscle loss. During follow-up, 1,901 participants developed probable sarcopenia and 277 developed confirmed sarcopenia. Individuals in the highest tertile of arterial stiffness index faced a 38% higher risk of probable sarcopenia and a 56% higher risk of confirmed sarcopenia compared with those in the lowest tertile. The dose-response relationship was nonlinear for probable sarcopenia but linear for confirmed sarcopenia. Biological age acceleration, measured by the Klemera-Doubal method, mediated 8.66% of the risk for probable sarcopenia and 18.85% for sarcopenia. In addition, frailty modified these relationships, as the associations between arterial stiffness and muscle loss were largely confined to non-frail participants.
Why it matters
The findings position arterial stiffness as an upstream contributor to muscle loss in aging. They also show that accelerated biological aging serves as a measurable pathway linking vascular dysfunction to musculoskeletal decline.
Caveats
The study is observational and cannot prove that arterial stiffness causes sarcopenia. In addition, the findings are derived from a single human cohort and require validation across more diverse populations.
