BACKGROUND Self-care behaviours are important to improve health outcomes in patients with heart failure. However, little is known about the factors related to the subdimensions of self-care behaviours in these patients. AIMS To identify the factors associated with the subdimensions of self-care behaviours among South Korean patients with heart failure. METHODS The participants in this cross-sectional descriptive study conducted between October 2016 and January 2017 were 178 patients with heart failure. Self-care behaviours were measured using the EHFScB-9, which has three subdimensions: autonomy-based adherence; provider-directed adherence; and consulting behaviours. Demographic characteristics, experience of heart failure education, physical function, patient health questionnaire-9, Pittsburgh sleep quality index and self-care confidence were also measured. Descriptive statistics and multiple linear regression analysis were conducted. RESULTS The mean age was 62 ± 12 years, and 37% were women. Younger age (P=0.023), no experience of heart failure education (P=0.039), poor physical function (P=0.003), poor sleep quality (P=0.037) and lower self-care confidence (P=0.001) were significantly associated with poor autonomy-based adherence. Being unemployed (P=0.042), poor sleep quality (P=0.042) and lower levels of self-care confidence (P=0.001) were associated with poor provider-directed adherence. Younger age (P=0.001) and lower self-care confidence (P=0.001) were associated with lower engagement in consulting behaviours. CONCLUSION The three subdimensions of self-care behaviours were associated with different psychosocial factors, necessitating the development of tailored interventions and educational materials based on unique self-care behaviour patterns in patients with heart failure.

韩国心力衰竭患者自我保健行为的相关因素

背景自我保健行为对于改善心力衰竭患者的健康结果很重要。然而，关于这些患者自我护理行为的子维度相关的因素知之甚少。目的 确定与韩国心力衰竭患者自我护理行为细分相关的因素。方法 在 2016 年 10 月至 2017 年 1 月期间进行的这项横断面描述性研究的参与者是 178 名心力衰竭患者。使用 EHFScB-9 测量自我护理行为，它具有三个子维度：基于自主的依从性；提供者指导的依从性；和咨询行为。人口学特征、心力衰竭教育经验、身体机能、患者健康问卷-9、匹兹堡睡眠质量指数和自我保健信心也被测量。进行了描述性统计和多元线性回归分析。结果 平均年龄为 62 ± 12 岁，37% 为女性。年龄较小（P=0.023）、无心力衰竭教育经历（P=0.039）、身体机能差（P=0.003）、睡眠质量差（P=0.037）和自理信心低下（P=0.001）显着与基于自主的依从性差有关。失业（P=0.042）、睡眠质量差（P=0.042）和自我保健信心水平较低（P=0.001）与提供者指导的依从性差有关。年龄较小（P=0.001）和自理信心较低（P=0.001）与咨询行为参与度较低有关。
