Exercise as a treatment for depression: A meta-analysis adjusting for publication bias

Schuch, F. B., Vancampfort, D., Richards, J., Rosenbaum, S., Ward, P. B., & Stubbs, B. (2016). Exercise as a treatment for depression: A meta-analysis adjusting for publication bias.

Level A Meta-analysis doi:10.1016/j.jpsychires.2016.02.023

What this study supports

Supports the claim that exercise had a large effect on depressive symptoms compared with control conditions, with larger effects for aerobic, moderate-to-vigorous and supervised exercise. A clinical population; not evidence about everyday mood regulation in healthy adults.

Who was studied: 25 randomised controlled trials of exercise in people with depression, 9 of them in major depressive disorder.
Design: Meta-analysis
Level of evidence: Syntheses of controlled studies: meta-analyses and systematic reviews of experiments and trials.

Claims that rest on it

Each claim states what the site asserts, at what strength, and with what caveat.

EmpiricalLevel AConfidence MODERATE

Randomised trials pooled in several meta-analyses associate regular physical activity with reductions in depressive and anxiety symptoms, in non-clinical adults and in people with depression, although the certainty of specific effect estimates is often low.

Scope: Structured physical activity interventions over weeks, compared with control conditions or usual care.
Caveat: Overlapping studies, unblinded participants, frequent risk of bias and low-quality reviews limit certainty; effect sizes differ widely between syntheses.

Level A Meta-analysis

Supports the claim that physical activity reduced depression by a medium effect (SMD = -0.50) and anxiety by a small effect (SMD = -0.38) in non-clinical adults. Aggregates meta-analyses, so overlap between included studies is possible.

Level A Meta-analysis

Supports the claim that walking or jogging, yoga and strength training were associated with moderate reductions in depression compared with active controls, with effects proportional to prescribed intensity. Only one study met criteria for low risk of bias, and confidence in the estimates was rated low to very low.

Effectiveness of physical activity interventions for improving depression, anxiety and distress: An overview of systematic reviews. doi:10.1136/bjsports-2022-106195

Level A Systematic review

Supports the claim that physical activity had medium effects on depression, anxiety and psychological distress compared with usual care across populations, with higher intensity associated with greater improvement. Most included reviews had critically low quality ratings.
