What this study supports

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.

Who was studied
218 randomised trials (14,170 participants) meeting clinical cut-offs for major depression.
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.
