Abstract：Objective To evaluate the effects of the intervention based on WeChat on blood pressure control in patients with essential hypertension. Methods The databases of CNKI，Wanfang，VIP，PubMed and the Cochrane Library were researched for the literatures about effects of the intervention based on WeChat on blood pressure control in patients with essential hypertension published from 2011 to 2018. These papers were retrieved and evaluated according to inclusion and exclusion criteria. Stata 12.0 software was used for meta analysis. Results Eleven out of 880 papers were included into meta analysis. There were 1 174 cases，with 587 cases in the experimental group and 587 cases in the control group. The results of the meta analysis showed that compared with traditional health intervention method，the intervention based on WeChat significantly reduced the level of systolic blood pressure（WMD=14.77，95%CI：11.76-17.77）and diastolic blood pressure（WMD=8.17，95%CI：5.67-10.67）of hypertensive patients. Subgroup analysis showed that the longer the intervention，the better the effects（P<0.05）. Conclusion The intervention based on WeChat is more helpful than traditional health intervention for blood pressure control of patients with essential hypertension.
