BACKGROUND: 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. METHODS: 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. RESULTS: 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 to -5.67, p < 0.00001) and diastolic blood pressure (mean difference -5.02, 95% CI -7.88 to -2.17, p < 0.00001). There is, however, no significant difference between Qigong and other aerobic exercises in reducing blood pressure. CONCLUSION: 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.
