MedPage Today (2/10, Jeffrey) reports, “Exercise effectively reduced symptoms of depression and anxiety, comparable to results seen with pharmacological or psychological interventions, according to a systematic umbrella review with a meta-meta-analysis of randomized trials.” Researchers observed that “exercise had a medium-sized effect on reducing depression symptoms (standardized mean difference [SMD] -0.61, 95% CI -0.69 to -0.54), while it had a small-to-medium effect on reducing anxiety symptoms (SMD -0.47).” They noted that “while exercise was effective across all age groups, the greatest benefits of exercise on depression were seen in adults ages 18 to 30 years (SMD -0.81), as well as among postnatal women (SMD -0.70).” The review was published in the British Journal of Sports Medicine.
