To identify prognostic factors for health outcomes following an eight-week supervised exercise therapy and education program for individuals with knee and hip osteoarthritis (OA) alone or with concomitant hypertension, heart or respiratory disease, diabetes, or depression.
We included individuals with knee and/or hip OA from the Good Life with osteoArthritis in Denmark (GLA:D
Data from 35,496 (40-m FPWT) and 37,576 (EQ-5D-5L and VAS) participants were included in the analyses. Clinically relevant associations were demonstrated between age, self-efficacy, self-rated health, and pain intensity with change in 40-m FPWT, EQ-5D-5L or VAS across comorbidity groups. Furthermore, anxiety, education, physical function, and smoking were associated with outcomes among subgroups having depression or diabetes in addition to OA.
Age, self-efficacy, self-rated health, and pain intensity may be prognostic of change in health outcomes following an eight-week exercise therapy and patient education program for individuals with OA, irrespective of comorbidities.
