Why the study?
The effect of mindfulness-based interventions on blood pressure and mental health in people with hypertension or prehypertension is not fully understood.
Do mindfulness-based interventions reduce blood pressure and improve mental health in patients with prehypertension or hypertension?
Do mindfulness-based interventions reduce blood pressure and improve mental health in patients with prehypertension or hypertension?
Mindfulness-based interventions significantly reduce systolic and diastolic blood pressure in patients with prehypertension or hypertension, supporting their use as an adjunct lifestyle modification.
MBIs reduce BP and mental health symptoms in pre/hypertension; supports adjunctive use and larger implementation trials.
Background: Hypertension and prehypertension has been widely recognized as the main contributor of global mortality. Evidence shows mindfulness-based interventions may reduce blood pressure and improve mental health. However, the effect of mindfulness-based interventions on blood pressure and mental health has not been fully understood. Methods: Potential studies published before May 24 th 2023 were identified by searching Embase, Ovid Emcare, PsycINFO, CINAHL, Web of Science, Cochrane, PubMed, China National Knowledge Infrastructure, Wanfang database, and VIP China Science. Additionally, two grey databases were searched: Mednar, WorldWideScience.org. The risk of bias in the included studies was assessed using the Cochrane Risk of Bias Assessment tool. The random-effects meta-analyses were conducted using Review Man 5.4 software and the key outcomes are presented as mean difference or standard mean difference and the 95% confidential interval. Results: Searches returned 802 studies in total, of which 12 were included (N = 715). The duration of interventions was 8 weeks in 10 trials and 6 weeks in one trial. Pooled effect sizes indicated reductions in systolic blood pressure (MD = -9.12, 95% CI [-12.18, -6.05], p < 0.001), diastolic blood pressure (MD = -5.66, 95% CI [-8.88, -2.43], p < 0.001), anxiety (SMD = -4.10; 95% CI [-6.49, -1.71], p < 0.001), depression (SMD = -1.70, 95 %CI [-2.95, -0.44], p < 0.001) and perceived stress (SMD = -5.91, 95 %CI [-8.74, -3.09], p < 0.001) at post-intervention. The findings from subgroup analyses are favorable for MBIs regardless of gender and baseline blood pressure with regard to BP reduction, with a more profound effect observed in participants with higher pre-intervention blood pressure. Conclusions: The results provide evidence for the positive role of mindfulness-based interventions in hypertension management. More large randomized control trials with sufficient statistical power and long-term follow-up are needed. Registration: The protocol had been registered with Prospero on October 2 nd 2021 (registration NO. CRD42021282504).
