Quality of Evidence Supporting the Effects of Tai Chi Exercise on Essential Hypertension: An Overview of Systematic Reviews and Meta-Analyses

Objectives

Tai Chi (TC) is a potential complementary treatment for essential hypertension (EH). This overview systematically summarizes and evaluates the existing evidence of TC in the therapy of EH.

Methods

Systematic reviews (SRs)/meta-analyses (MAs) on TC interventions for EH were comprehensively searched in seven databases. Methodological quality, risk of bias, reporting quality, and quality of evidence were assessed by means of the Assessment of Multiple Systematic Reviews 2 (AMSTAR-2), the Risk of Bias in Systematic (ROBIS) scale, the list of Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA), as well as the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system.

Results

Twelve published SRs/MAs were included in our study. According to the results of the AMSTAR-2, ROBIS, PRISMA, and GRADE assessment, only 1 SR/MA was assessed as high quality and only 1 SR/MA was assessed as low risk of bias. Only 2 SRs/MAs have been fully reported on the checklist. In addition to that, the quality of evidence was assessed for a total of 69 outcome indicators extracted from the SRs/MAs included in this overview, and only 3 items were assessed as high quality.

Conclusions

TC may be an effective and safe complementary treatment for EH. However, this conclusion must be approached with caution, as the quality of the evidence provided by the SRs/MAs is usually low.

Current Evidence on Traditional Chinese Exercises for Quality of Life in Patients With Essential Hypertension: A Systematic Review and Meta-Analysis

Essential hypertension is one of the most common chronic diseases seen in primary human health care that could lead to various health problems and reduce the quality of life (QOL). This study was performed to evaluate the effects of traditional Chinese exercises (TCE) on QOL in patients with essential hypertension. Three English databases and one Chinese database were searched for randomized controlled trials (RCTs) until August 2020. A total of 13 RCTs with 1,361 hypertensive patients met the inclusion criteria, 10 trials employed Tai Chi and 3 trials employed Qigong, including Dongeui Qinggong, Yijinjing, and Wuqinxi. Despite a large heterogeneity within studies, it is demonstrated that TCE may be an effective therapy to improve the QOL of hypertensive patients. More specific, compared with no intervention, the meta-analysis presented that Tai Chi significantly improved both the physical and mental component of the 36-item short-form health survey (SF-36) QOL scale, and it was found that the simplified 24-form Tai Chi with a frequency of 30–50 min per session at five to eight sessions per week was the most commonly used setting. The pooling also revealed that Tai Chi and Qigong had some significantly positive effects on QOL based on other scales. However, more rigorously designed RCTs are warranted for further verification. This systematic review and meta-analysis of RCTs demonstrated that Tai Chi may be an effective therapy to improve the QOL of patients with essential hypertension. All these findings provide helpful information for hypertensive patients and medical personnel.

Effects of Tai Chi exercise on cardiovascular disease risk factors and quality of life in adults with essential hypertension: A meta-analysis

BACKGROUND

Hypertension is the major attributable risk factor for cardiovascular disease. The effect of Tai Chi on essential hypertension (EH) is contentious.

OBJECTIVES

In this study, we investigated the effects of Tai Chi on the risk factors for cardiovascular disease and quality of life in adults with EH.

METHODS

Using data collected from 15 databases up to December 2018, we meta-analyzed randomized controlled trials of the effect of Tai Chi on EH.

RESULTS

Tai Chi exercise was associated with lower systolic blood pressure (SBP) (WMD -12.47, 95%CI -16.00 to -8.94, P < 0.001) and diastolic blood pressure (DBP) (WMD -6.46, 95%CI -8.28 to -4.64, P < 0.001); better quality of life (SMD 0.62, 95% CI 0.35 to 0.90, P < 0.001); lower lipid profiles, including total cholesterol (WMD -0.49, 95% CI -0.62 to -0.37, P < 0.001), triglycerides (WMD -0.49, 95% CI -0.92 to -0.07, P = 0.02), and low-density lipoprotein-cholesterol (LDL-C) (WMD -0.86, 95% CI -1.30 to -0.43, P < 0.001); and lower blood glucose (WMD -0.91, 95% CI -1.59 to -0.23, P = 0.009). Tai Chi had no significant effect on high-density lipoprotein-cholesterol (WMD -0.92, 95% CI -2.21 to -0.37, P = 0.16).

CONCLUSIONS

Tai Chi lowers blood pressure, total cholesterol, triglycerides, LDL-C, and blood glucose and significantly increases the quality of life in adults with EH. There is strong evidence for the short-term efficacy of Tai Chi exercises. Larger well-designed RCTs focused on the long-term effect of Tai Chi exercises and patient adherence are needed.
