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.

摘要： 背景　随着科技的发展和智能手机的普及，微信已成为社区高血压管理的潜在工具。目的　研究社区中老年正常高值血压及高血压人群微信干预的依从性及其影响因素。方法　2018年11月—2019年5月，采用便利抽样法抽取广州市越秀区白云街道中老年正常高值血压及高血压人群，利用微信进行6个月的分层干预，前3个月为健康教育阶段，后3个月为健康行为促进阶段。对干预过程中干预对象的依从性进行描述，并采用Logistic回归分析方法对依从性的影响因素进行分析。结果　共纳入研究对象209人，干预6个月后，167人（79.9%）完成干预过程。其中，依从性良好者81人（48.5% ），依从性差者86人（51.5%）。多因素Logistic回归分析结果显示，文化程度、目前婚姻状况、合并症情况、饮酒情况是社区中老年正常高值血压及高血压人群微信干预依从性的影响因素（P<0.05）。结论　社区中老年正常高值血压及高血压人群微信干预依从性有待提高，并受多种因素的影响。在干预过程中，应重点关注文化程度低、有配偶、无合并症、饮酒的干预对象。
