This study assessed the effects of Health Qigong on sleep quality in adults.
Systematic review and meta-analysis.
We searched 10 databases to identify relevant randomized controlled trials (RCTs) published in English or Chinese languages that evaluated the effects of Health Qigong on sleep quality in participants aged ≥18 years old with or without diseases in comparison with any type of controls. Quality of the included studies was assessed by the revised Cochrane risk-of-bias tool for randomized trials. The between-group treatment effect size was estimated by calculating Hedges' g and associated confidence interval (CI) through a random effects model. Cochran's Q test and I were used to determine heterogeneity.
The initial search yielded 730 articles, of which 13 studies involving 1147 participants were included in the systematic review and meta-analysis. The overall effect size was -0.955 (95 % CI: -1.601 to -0.309, p = 0.004). A homogeneity test revealed high heterogeneity (Q = 278.187, p < 0.001, I = 95.686 %). A sensitivity analysis was conducted through the exclusion of an outlier, which revealed a small but statistically significant effect size (Hedges' g = -0.423, 95 % CI: -0.603 to -0.243, p < 0.001; Q = 18.073, p = 0.08, I = 39.137 %).
Our study results suggest that Health Qigong is beneficial for improving sleep quality in adults with and without disease. However, the effects of Health Qigong could be partially due to nonspecific effects as half of the included studies did not employ an active control.
本研究评估了健身气功对成年人睡眠质量的影响。
系统评价和荟萃分析。
我们检索了10个数据库，以识别以英文或中文发表的相关随机对照试验（RCT），这些试验评估了健身气功对18岁及以上有或无疾病参与者睡眠质量的影响，并与任何类型的对照组进行比较。纳入研究的质量通过修订后的Cochrane随机试验偏倚风险工具进行评估。通过随机效应模型计算Hedges' g和相关置信区间（CI）来估计组间治疗效应大小。使用Cochran's Q检验和I²来确定异质性。
初步检索得到730篇文章，其中13项研究涉及1147名参与者被纳入系统评价和荟萃分析。总体效应大小为-0.955（95% CI：-1.601至-0.309，p = 0.004）。同质性检验显示高度异质性（Q = 278.187，p < 0.001，I² = 95.686%）。通过排除一个离群值进行敏感性分析，结果显示效应大小虽小但具有统计学意义（Hedges' g = -0.423，95% CI：-0.603至-0.243，p < 0.001；Q = 18.073，p = 0.08，I² = 39.137%）。
我们的研究结果表明，健身气功对有疾病和无疾病的成年人改善睡眠质量有益。然而，健身气功的效果可能部分归因于非特异性效应，因为纳入研究中有一半未采用活性对照。
