- Background Evidence-based treatment of depression continues to grow, but successful treatment and maintenance of treatment response remains limited.Aims To compare the effectiveness of exercise, internet-based cognitive-behavioural therapy (ICBT) and usual care for depression.Method A multicentre, three-group parallel, randomised controlled trial was conducted with assessment at 3 months (posttreatment) and 12 months (primary end-point). Outcome assessors were masked to group allocation. Computer-generated allocation was performed externally in blocks of 36 and the ratio of participants per group was 1:1:1. In total, 945 adults with mild to moderate depression aged 18-71 years were recruited from primary healthcare centres located throughout Sweden. Participants were randomly assigned to one of three 12-week interventions: supervised group exercise, clinician-supported ICBT or usual care by a physician. The primary outcome was depression severity assessed by the Montgomery-Åsberg Depression Rating Scale (MADRS).Results The response rate at 12-month follow-up was 84%. Depression severity reduced significantly in all three treatment groups in a quadratic trend over time. Mean differences in MADRS score at 12 months were 12.1 (ICBT), 11.4 (exercise) and 9.7 (usual care). At the primary end-point the group x time interaction was significant for both exercise and ICBT. Effect sizes for both interventions were small to moderate.Conclusions The long-term treatment effects reported here suggest that prescribed exercise and clinician-supported ICBT should be considered for the treatment of mild to moderate depression in adults.

- OBJECTIVE: Exercise is an efficacious stand-alone therapy for mild-to-moderate depression, but little is known about the influence of physical activity levels on responses to depression treatment. This study aimed to prospectively assess the association between self-reported habitual physical activity levels and depression severity following a 12-week intervention.METHOD: 629 adults (75% women; aged 18-71years) with mild-to-moderate depression were recruited from primary care centres across Sweden and treated for 12weeks. The interventions included internet-based cognitive behavioural therapy (ICBT) and 'usual care' (CBT or supportive counselling). One third of all participants were taking anti-depressant medication. The primary outcome was the change in depression severity assessed using the Montgomery-Åsberg Depression Rating Scale (MADRS). Habitual physical activity levels were self-rated and based on the estimated frequency, duration and intensity of total physical activity, including planned exercise, 'during a typical week'. Prospective associations were explored using linear regression models (percentage change) with 95% confidence intervals (CI's).RESULTS: Following adjustment for relevant covariates, high levels of habitual physical activity were associated with larger relative reductions in depression severity compared to low physical activity (β=-9.19, 95% CI=-18.46, -0.09, p=0.052) and moderate physical activity (β=-10.81, 95% CI=-21.09, -0.53, p<0.05), respectively.CONCLUSION: Adults who routinely engage in high levels of physical activity respond more favourably to CBT-focused depression treatments than adults who engage in low-to-moderate levels of activity. The optimal level of physical activity associated with reductions in depression severity corresponds to consensus recommendations for maximizing general health. One limitation is the use of self-reported physical activity data.
