The effects of exercise on anxiety and depression in adults with cancer: A meta-review of meta-analyses
Bibliographic record
Abstract
Background This meta-review aimed to synthesize the evidence of the effects of exercise on anxiety and depression symptoms amongst adults with cancer, and cancer-survivors, comparing effects sizes between meta-analysis.Methods Major databases were searched up to February 9, 2024 for meta-analyses evaluating the effects of exercise, using anxiety and/or depression scales. Effect size (ES) values were calculated as standardized differences in the means and expressed as the Standardized Mean Difference (SMD) with the 95% confidence interval (95%CI). A total of eight unique meta-analyses were included.Results Among meta-analyses examining both anxiety and depression symptoms overall, a small beneficial effect of exercise was shown [SMD = 0.41 (0.25–0.57); p < 0.0001]. Subgroup analyses revealed that exercise has a small effect on decreasing anxiety [SMD = 0.42 (0.04–0.79); p = 0.027], and depressive symptoms [SMD = 0.38 (0.21–0.56); p < 0.0001]. In addition, aerobic exercise has a moderate effect on reducing depressive symptoms [SMD = 0.54 (0.16–0.93); p = 0.005], whereas resistance exercise has no effect. Subgroup analyses by type of cancer observed a moderate effect on decreasing depressive symptoms in patients with breast cancer [SMD = 0.51 (0.27–0.74); p < 0.0001].Conclusions Exercise (specifically aerobic) should be considered by healthcare professionals as a strategy to treat/manage symptoms of anxiety and depression amongst adults with cancer and cancer-survivors.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
