Physical assessment in older adults with intellectual disabilities: Results of the HA-ID study

Aim: Being physical fit is an essential factor in healthy aging, and physical fitness tests can be important tools in the care of the aging population with intellectual disabilities (ID). In the HA-ID study, the feasibility and reliability of eight physical fitness tests have previously been studied for older adults (≥50 years) with ID. In the current study, the predictive value of these tests for a decline in daily functioning was assessed.

Method: At baseline, an extensive physical fitness assessment was performed in 1,050 older adults. Professional caregivers completed questionnaires regarding daily functioning, both at baseline and at follow-up 3 years later. Multiple linear regression analyses were used to assess the predictive value of physical fitness tests for a decline in daily functioning.

Results: Daily functioning significantly declined over the 3-year follow-up period. Most physical fitness tests were significant predictors of both a decline in the ability to perform basic and instrumental activities of daily living and of a decline in mobility.

Conclusions: With these, and previous results of the HA-ID study, a physical fitness test battery has been composed of suitable physical fitness tests.
