Low level of physical activity is common among hospitalized older adults and is associated with worse prognosis. The aim of this paper is to describe the pattern and level of physical activity in a group of hospitalized older adults and to identify factors associated with physical activity.
The authors measured physical activity on day three after admission using accelerometer based activity monitors and time in upright position as outcome measure. They collected data of physical function, cognitive function, personal Activities of Daily Living and burden of disease. They analyzed data using univariable and multivariable linear regression models, with time in upright position as dependent variable.
Participants’ mean time in upright position one day early after admission was almost two hours, indicating a high level of physical activity compared to results from similar studies. Physical function was the only variable significantly associated with physical activity indicating that SPPB could be a useful screening tool and that mobilization regimes should be delivered routinely for patients with reduced physical function.
