Background
To assess and compare the predictive value of physical function measurements (PFMs) for all‐cause mortality in older men and to evaluate the Timed Up and Go test (TUG) as a predictor in subjects with underlying comorbidity.
Design
Observational study of a population‐based sample of 352 ambulatory older men aged 71–86 at study baseline. The Rapid disability rating scale‐2, 36‐Item short form health survey, Grip strength, Five times sit‐to‐stand test, Standing balance, and TUG were determined at baseline. Associations with all‐cause mortality were assessed using Cox proportional hazard analyses. Age, Body mass index (BMI), smoking status, education, physical activity and cognitive status were included as confounders. Follow‐up exceeded 15 years. Comorbidity status was categorized into cardiovascular disease, chronic obstructive pulmonary disease (COPD) and diabetes mellitus.
Results
All examined PFMs were associated with all‐cause mortality. TUG was the best predictor (adjusted HR per SD increase = 1·58, 95% CI = 1·40–1·79, P < 0·001) for global mortality and continued to be predictive in subjects with cardiovascular disease (adjusted HR per SD increase = 1·80, 95% CI = 1·40–2·33, P < 0·001).
Conclusions
The assessment of physical functioning is important in the evaluation of older persons. We encourage the use of the TUG as a reliable, quick and feasible screening tool in clinical settings.
