Abstract

OBJECTIVE: The authors examined the prospective relationship between physical activity and incident depression and explored potential moderators. METHOD: Prospective cohort studies evaluating incident depression were searched from database inception through Oct. 18, 2017, on PubMed, PsycINFO, Embase, and SPORTDiscus. Demographic and clinical data, data on physical activity and depression assessments, and odds ratios, relative risks, and hazard ratios with 95% confidence intervals were extracted. Random-effects meta-analyses were conducted, and the potential sources of heterogeneity were explored. Methodological quality was assessed using the Newcastle-Ottawa Scale. RESULTS: =0.00). Furthermore, physical activity had a protective effect against the emergence of depression in youths (adjusted odds ratio=0.90, 95% CI=0.83, 0.98), in adults (adjusted odds ratio=0.78, 95% CI=0.70, 0.87), and in elderly persons (adjusted odds ratio=0.79, 95% CI=0.72, 0.86). Protective effects against depression were found across geographical regions, with adjusted odds ratios ranging from 0.65 to 0.84 in Asia, Europe, North America, and Oceania, and against increased incidence of positive screen for depressive symptoms (adjusted odds ratio=0.84, 95% CI=0.79, 0.89) or major depression diagnosis (adjusted odds ratio=0.86, 95% CI=0.75, 0.98). No moderators were identified. Results were consistent for unadjusted odds ratios and for adjusted and unadjusted relative risks/hazard ratios. Overall study quality was moderate to high (Newcastle-Ottawa Scale score, 6.3). Although significant publication bias was found, adjusting for this did not change the magnitude of the associations. CONCLUSIONS: Available evidence supports the notion that physical activity can confer protection against the emergence of depression regardless of age and geographical region.

  • Physical exercise for approximately 45 minutes per day can significantly reduce the risk of MDD.

    “Furthermore, physical exercise for approximately 45 minutes per day can significantly reduce the risk of MDD. 320 , 321”

    From Major depressive disorder: hypothesis, mechanism, prevention and treatment (2024) · cites this paper as [321]

    The major-depression subgroup results show a significant association between higher physical activity and lower risk of incident major depression. But Limitations and Future Research says the studies cannot establish a minimum or optimal dose, so the paper does not support approximately 45 minutes per day specifically. The evidence is from prospective cohorts and does not establish that exercise itself causes the reduction. (LLM, conf=0.90)

  • Self-reported physical activity or exercise interventions may have potential beneficial effects to lower the incidence of depression and lower the severity of obstructive sleep apnea and associated comorbidities.

    “Finally, self-reported physical activity or exercise interventions may have potential beneficial effects to lower the incidence of depression20 and lower the severity of obstructive sleep apnea and associated comorbidities21.”

    From Association of step counts over time with the risk of chronic disease in the All of Us Research Program (2022) · cites this paper as [20]

    The Abstract and Conclusions report that higher physical activity is associated with lower odds of incident depression, supporting the depression portion attributed to this source. But the paper analyzes prospective cohorts, not exercise interventions; its Conclusions say randomized trials are needed to determine whether increasing physical activity prevents depression. The sleep-apnea portion is attached to a different citation and is not assessed here. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Recent large-scale observational and Mendelian randomisation studies suggest that higher levels of physical activity can confer protection against mental disorders.

    “There are recent large-scale observational [18] and Mendelian randomisation studies [124] suggesting that higher levels of PA can confer protection against mental disorders.”

    From Exercise as Medicine for Mental and Substance Use Disorders: A Meta-review of the Benefits for Neuropsychiatric and Cognitive Outcomes (2020) · cites this paper as [18]

    The Abstract and Discussion report a large meta-analysis of prospective observational studies associating higher physical activity with lower odds of future depression. This supports the observational-study portion of the citing sentence, but the source examines depression, not mental disorders generally. The Mendelian randomisation studies are attributed to a separate citation. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Adjusting for baseline depressive symptoms, body mass index, smoking status, age, gender and other confounds did not alter the findings for physical activity and depression.

    “Adjusting for baseline depressive symptoms, body mass index, smoking status, age, gender and other confounds did not alter the findings.”

    From A meta-review of "lifestyle psychiatry": the role of exercise, smoking, diet and sleep in the prevention and treatment of mental disorders (2020) · cites this paper as [29]

    The Physical Activity and Incident Depression results report that the protective association remained significant in adjusted odds-ratio subgroups accounting for the listed confounders. However, Limitations and Future Research notes that the single study adjusting relative risk for baseline depressive symptoms found no significant association. Thus, saying adjustment did not alter the findings without qualifying the analysis is too broad; our copy provides no page number for these passages. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Similar protective effects of physical activity were found in children/adolescents (n=3, OR=0.907, 95% CI: 0.836-0.985), adults (n=16, OR=0.787, 95% CI: 0.707-0.877) and older adults (n=16, OR=0.794, 95% CI: 0.726-0.868).

    “and in children/adolescents (n=3, OR=0.907, 95% CI: 0.836-0.985), adults (n=16, OR=0.787, 95% CI: 0.707-0.877) or older adults (n=16, OR=0.794, 95% CI: 0.726-0.868).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
