Abstract：
The relative efficacy of various mind-body exercises in the treatment of depressive symptoms remains uncertain. We examined the optimal modalities (Tai Chi, qigong, yoga) and dose of mind-body exercise to improve depressive symptoms in adults. A systematic search of six electronic databases for randomized controlled trials on the relationship between exercise and depression was carried out, encompassing data from their inception up to November 2023. Pairwise analyses, network analyses and dose-response meta-analyses using random-effects models were performed to analyse the effect of exercise on depression. Forty studies were included. Results showed that Yoga [standardised mean difference (SMD) = -0.55; 95% confidence interval (CI): (-0.76, -0.35)] was the most effective form of exercise for improving depressive symptoms, followed by Qigong (SMD = -0.52; 95%CI: -0.92, -0.11) and Tai Chi exercise (SMD = -0.42; 95%CI: -0.71, -0.13). In addition, a non-linear dose-response relationship was found between overall mind-body exercise dose and depression levels and a significant response was observed after 260 METs-min. Our study examined the effectiveness of different types of mind-body exercise in improving depression and found that yoga may be the most effective adjunctive intervention. There was a non-linear dose-response relationship between total exercise and depression levels. However, caution should be exercised in interpreting and applying these results.
摘要：
各种身心锻炼在治疗抑郁症状方面的相对功效仍不确定。我们检查了最佳模式(太极拳，气功,瑜伽）和剂量的身心锻炼，以改善成人的抑郁症状。对六个电子数据库进行了系统的搜索，以进行有关运动与抑郁之间关系的随机对照试验，涵盖从成立到2023年11月的数据。成对分析，使用随机效应模型进行网络分析和剂量-反应荟萃分析,以分析运动对抑郁的影响.包括40项研究。结果表明，瑜伽[标准化平均差（SMD）=-0.55；95％置信区间（CI）：（-0.76，-0.35）]是改善抑郁症状的最有效运动形式，其次是气功（SMD=-0.52；95CI：-0.92，-0.11）和太极拳运动（SMD=-0.42；95CI：-0.71，-0.13）。此外,在整体身心运动剂量和抑郁水平之间发现了非线性的剂量-反应关系,并且在260METs-min后观察到显著的反应.我们的研究检查了不同类型的身心锻炼在改善抑郁症方面的有效性，发现瑜伽可能是最有效的辅助干预措施。总运动和抑郁水平之间存在非线性剂量反应关系。然而,在解释和应用这些结果时应谨慎行事。
