Abstract: Background　The development of science and technology and the popularity of smart phones have made WeChat a potential tool for community-based hypertension management. Objective　To study the adherence to WeChat interventions and associated factors in middle-aged and elderly people with prehypertension and hypertension in the community. Methods　From November 2018 to May 2019，we delivered a six-month WeChat-based tiered interventions（first three-month health education，then three-month health behavior promotion） to middle-aged and elderly people with prehypertension and hypertension selected using convenient sampling method from Baiyun Subdistrict，Guangzhou's Yuexiu District. A descriptive analysis of the adherence to the interventions was performed. Logistic regression analysis was used to identify the associated factors of adherence to the interventions. Results　A total of 209 cases were enrolled，and 167（79.9%）of them completed the study，including 81 with good intervention adherence，and 86（51.5%）with poor adherence. Multivariate Logistic regression analysis found that education level，current marital status，comorbidities，and drinking status were influencing factors of adherence to WeChat interventions in middle-aged and elderly people with prehypertension and hypertension in the community（P<0.05）. Conclusion　The adherence to WeChat-based interventions in these people may be associated with multiple factors，and needs to be improved. To do this，priority during the intervention delivery shall be given to individuals having a low level of education，spouse，at least one comorbidity，or drinking.
