Artery calcium buildup is linked to frailty in UK adults
Adults with moderate or high artery calcium buildup had 1.27 or 1.58 times the odds of frailty, respectively, compared with low buildup.
Limit: Frailty could precede artery calcium buildup; the data do not resolve their order

Researchers studied 49,081 community-dwelling adults in the UK Biobank Imaging Study without diagnosed atherosclerotic cardiovascular disease, which involves fatty deposits in arteries. This cross-sectional observational study used a validated machine-learning model to score calcium buildup in the abdominal aorta, the main artery passing through the abdomen.
Researchers assessed physical frailty using weak grip, slow walking, weight loss, exhaustion and physical inactivity. Three or more deficits counted as frailty; one or two counted as pre-frailty. One in five participants had moderate or high calcium buildup. After accounting for multiple other factors, both groups had greater odds of frailty than participants with low buildup. Separate analyses of men and women found similar associations with frailty.
Why it matters
The findings bear on recognizing physical frailty in aging. The authors suggest that artery calcium visible on spine images taken during routine bone density testing could help detect frailty early.
Caveats
The cross-sectional data cannot show whether artery calcium buildup preceded or caused frailty. The findings do not establish the same association in people with diagnosed atherosclerotic cardiovascular disease.
