Exercise for patients with major depression: a protocol for a systematic review with meta-analysis and trial...

Area of Science:

• Clinical Psychology
• Exercise Science
• Psychiatry

Background:

• Major depression affects 17% of the population, representing a significant global health burden.
• Current antidepressant treatments have limited efficacy, prompting investigation into alternative therapies like exercise.
• Previous reviews have not specifically focused on exercise interventions for adults diagnosed with major depression.

Purpose of the Study:

• To systematically review the beneficial and harmful effects of exercise in adults with major depression.
• To compare exercise interventions against treatment as usual, with or without co-interventions.

Main Methods:

• A systematic review and meta-analysis of randomized clinical trials involving adults with major depression.
• Consideration of bias risk, heterogeneity (meta-regression, subgroup analyses), and random errors (trial sequential analysis).
• Evaluation of outcomes including depression severity, remission rates, and suicidal ideation.

Main Results:

• Analysis of individual trial effect estimates, incorporating bias risk assessment.
• Exploration of heterogeneity through meta-regression and subgroup analyses.
• Control for random errors using trial sequential analysis.

Conclusions:

• Findings will inform health authorities and clinicians on the utility of exercise as a treatment for major depression.
• Evidence-based guidance on incorporating exercise into depression management strategies.
