Abstract Title:
Yoga as Antihypertensive Lifestyle Therapy: A Systematic Review and Meta-analysis.
Abstract:
OBJECTIVE: To investigate the efficacy of yoga as antihypertensive lifestyle therapy and identify moderators that account for variability in the blood pressure (BP) response to yoga.METHODS: We systematically searched 6 electronic databases from inception through June 4, 2018, for articles published in English language journals on trials of yoga interventions that involved adult participants, reported preintervention and postintervention BP, and had a nonexercise/nondiet control group. Our search yielded 49 qualifying controlled trials (56 interventions). We (1) evaluated the risk of bias and methodological study quality, (2) performed meta-regression analysis following random-effects assumptions, and (3) generated additive models that represented the largest possible clinically relevant BP reductions.RESULTS: On average, the 3517 trial participants were middle-aged (49.2±19.5 years), overweight (27.9±3.6 kg/m) adults with high BP (systolic BP, 129.3±13.3 mm Hg; diastolic BP, 80.7±8.4 mm Hg). Yoga was practiced 4.8±3.4 sessions per week for 59.2±25.0 minutes per session for 13.2±7.5 weeks. On average, yoga elicited moderate reductions in systolic BP (weighted mean effect size, -0.47; 95% CI, -0.62-0.32, -5.0 mm Hg) and diastolic BP (weighted mean effect size, -0.47; 95% CI, -0.61 to -0.32; -3.9 mm Hg) compared with controls (P
