Hypertension has been a global public health problem. Qigong as a complementary and alternative therapy is often used to reduce blood pressure. The aim of this meta-analysis was to investigate the effects of Qigong on blood pressure in hypertensive patients.
Six electronic resource databases were searched from inception to January 2019, and randomized controlled trials of Qigong on hypertension were retrieved. Meta-analysis was conducted according to the guidelines of the Cochrane Collaboration, and Review Manager 5.3 was applied. Two researchers independently identified articles to include based on inclusion/exclusion criteria, data extraction, and quality evaluation.
Fourteen studies, with 829 individuals, were included. The meta-analysis demonstrates that, compared with no exercise, Qigong has significant positive effects on systolic blood pressure (mean difference = -8.90, 95% CI (-12.13, -5.67), < 0.00001) and diastolic blood pressure (mean difference = -5.02, 95% CI (-7.88, -2.17), < 0.00001). There is, however, no significant difference between Qigong and other aerobic exercises in reducing blood pressure.
Qigong can effectively reduce blood pressure levels. Longer-term engagement in the practice has an even better effect in hypertension patients. However, the conclusion of this study still needs to be verified by more high-quality studies.
高血压一直是一个全球性的公共卫生问题。气功作为一种补充替代疗法，常被用于降低血压。本荟萃分析的目的是研究气功对高血压患者血压的影响。
检索了从建库至2019年1月的六个电子资源数据库，检索关于气功治疗高血压的随机对照试验。根据Cochrane协作网的指南进行荟萃分析，并应用Review Manager 5.3软件。两名研究人员根据纳入/排除标准、数据提取和质量评估，独立确定纳入的文章。
纳入了14项研究，共829例个体。荟萃分析表明，与不运动相比，气功对收缩压（平均差值=-8.90，95%可信区间（-12.13，-5.67），P<0.00001）和舒张压（平均差值=-5.02，95%可信区间（-7.88，-2.17），P<0.00001）有显著的积极影响。然而，在降低血压方面，气功与其他有氧运动之间没有显著差异。
气功可以有效降低血压水平。长期练习对高血压患者有更好的效果。然而，本研究的结论仍需更多高质量研究加以验证。
