Physical activity and health-related quality of life in men and women with hip and/or knee osteoarthritis before and after a supported self-management programme - a prospective observational study

Purpose To study differences between men and women in physical activity (PA) and health-related quality of life (HRQoL) before and after participating in a supported osteoarthritis (OA) self-management programme. Materials and methods A prospective observational study using data from a Swedish National Quality Register. Patients recorded between 2008 and 2013 with hip and/or knee OA with data at baseline, at 3 and 12 months follow-up (n = 7628) were included. Outcome measures were patient-reported PA and HRQoL (EQ-5D-3L). Results A greater proportion of men (p = 0.002) changed to being physically active >= 150 min/week at 3 months follow-up. The proportion of women being physically active >= 150 min/week was larger than for men at baseline (p = 0.003) and at follow-up at 12 months (p = 0.035). Women reported lower HRQoL than men at baseline (p < 0.001), at follow-up at 3 (p < 0.001) and 12 months (p = 0.010). There were no differences between men and women in change in HRQoL at 3 (p = 0.629) and 12 months (p = 0.577) follow-up. Conclusions This study showed differences between men and women in PA and HRQoL before and after participating in a supported OA self-management programme. These differences should be considered when supporting PA and HRQoL.
