高血压是危害健康的常见慢性病，易导致多种并发症，并给人们与社会带来负担。高血压在老年人群中发病率较高，随着年龄增长，在各因素的影响下，患者的治疗依从性有所下降，最终导致血压控制不佳，与心血管相关事件具有明确的相关性。知信行模式是促进人类健康行为的基本模式之一，通过有效的健康干预可提高老年高血压患者对疾病的认知水平，缓解消极情绪，形成积极的应对态度，最终提高治疗依从性及治疗效果，降低并发症的发生率和死亡率。本文对高血压疾病背景、知信行模式的概念及其在高血压中的研究现状进行综述，旨在分析高血压群体中知信行理念的应用及带来的影响，为高血压健康教育、健康管理等工作提供借鉴，减少患者的疾病负担。

Hypertension is a common chronic disease that can endanger people’s health, which can cause a variety of complications and bring burden to people and society. The incidence rate of hypertension is high in elder patients. As age increased, the treatment compliance of patients with hypertension decreased under the influence of various factors, which can lead to poor blood pressure control. Poor blood pressure control has clearly correlation with cardiovascular disease. Knowledge, attitude and practice (KAP) is one of the basic pattern to promote human health behavior. Effective health intervention is helpful to improve cognitive level of elderly patients with hypertension, alleviate negative emotions, develop positive attitude to disease, which can improve treatment compliance and treatment effect and reduce the incidence of complications and mortality. This paper reviews the concept of KAP theory and its research status in hypertension, aiming to analyze the application and influence of KAP in hypertension population, so as to provide reference for health education and health management, and reduce the disease burden of the public.
