Background Osteoarthritis is one of the leading causes to inactivity worldwide (1). Inactivity is a risk factor for progress of osteoarthritis as well as for ill health (2, 3, 4). To maintain good health it is recommended to be physically active at least 150 minutes per week at moderate intensity (2).

Objectives The purpose of this study was to evaluate how a supported osteoarthritis self-management programme influenced the proportion of patients involved in health enhancing physical activity (HEPA) at 3 and 12 months follow-up, and how level of physical activity was influenced by body mass index (BMI), gender, age and comorbidity among patients with hip or knee osteoarthritis.

Methods 6810 patients were included in this observational study. HEPA was defined as self-reported physical activity of at least moderate intensity either a) at least 30 minutes per day on 4 days or more per week, or b) at least 150 minutes per week. HEPA was assessed at baseline, and again at 3 and 12 months follow-up. Cochran's Q test was used to determine change in physical activity over time. The association between level of physical activity and time, age, BMI, sex, and Charnley index were investigated using generalized estimation equation (GEE) model.

Results The proportion of patients who reached the level of HEPA increased from 77% to 82% from baseline to 3 month follow-up. At 12 months the proportion of patients who reached the level of HEPA was 76%. Not reaching the level of HEPA was associated with overweight, obesity, male gender and Charnley category C, i.e. osteoarthritis in multiple joint sites (hip and knee), or presence of any other disease that affects walking ability.

Conclusions The supported osteoarthritis self management programme gave a small but for the individual and the society significant effect on the percentage of patients who reached the level of HEPA at 3 months. Improvements were lost after 12 months. Patients with owerweight, obesity, multiple joint sites involved or comorbidities may need additional support to reach or maintain HEPA.
