ABSTRACT
Objective To evaluate the effects of acupuncture combined with lifestyle modification for essential hypertension by Meta-analysis. Methods Clinical randomized controlled trial literature about acupuncture combined with lifestyle modification for essential hypertension in CNKI, WanFang Data, CBM, VIP, PubMed, Embase, and Web of Science since establishment to February 20, 2017 were retrieved. Data extraction and quality assessment of studies were conducted by two researchers independently, and the Meta-analysis was performed by the software of RevMan5.3. Results 5 articles involving 467 patients were included. The results of Meta-analysis showed that acupuncture combined with lifestyle modification had more significant effect than lifestyle modification alone in lowing SBP [SMD=-1.52(-2.40,-0.64)], in lowing DBP [SMD=-1.02(-2.01,-0.03)], total effective rates [RR=1.27(1.13, 1.43)]. Conclusion Compared with lifestyle modification alone, acupuncture combined with lifestyle modification have significant effects for patients with essential hypertension, but because of the fewer studies included, bigger heterogeneity between studies and the lower quality of included studies still exist, the results should be further verified, and clinical applications should be treated with caution.
