Sedentary behaviours may be related to factors such as self-efficacy, mood and social support. However, there is a paucity of longitudinal follow-up studies examining factors related to sedentary behaviour from physical-psychosocial perspectives in patients with heart failure.
The purpose of this study was to explore the multidimensional associated factors and impacts of sedentary behaviour in heart failure patients.
A longitudinal design was used. A convenience sample of 128 heart failure patients recruited from two large medical centres in northern Taiwan was obtained. Patients were interviewed with structured questionnaires to assess physical activity, symptom distress, exercise self-efficacy, anxiety and depression, social support, sleep quality and quality of life before discharge and at 3 and 6 months after discharge.
Heart failure patients reported low physical activity and tended to be sedentary. Sedentary behaviour was gradually reduced from hospitalization to 6 months after discharge. Sleep quality, quality of life, analgesic use, symptom distress and exercise self-efficacy were significant associated factors that explained 42.1-51% of the variance in sedentary behaviour. Patients with high sedentary behaviour had significantly greater depression and poorer sleep and quality of life than those with low sedentary behaviour at hospitalization and showed a significant improvement in depression at 3 and 6 months after discharge.
Sedentary behaviour is common in heart failure patients and has impacts on depression and quality of life. An appropriate physical activity programme focusing on disease self-management and enhancing self-efficacy is needed for heart failure patients to improve their sedentary behaviour and quality of life.
久坐行为可能与自我效能感、情绪和社会支持等因素有关。然而，从身心社会角度来看，针对心力衰竭患者久坐行为相关因素的纵向随访研究较少。
本研究旨在探讨心力衰竭患者久坐行为的多维相关因素及其影响。
采用纵向设计。在台湾北部的两家大型医疗中心，便利选取了 128 例心力衰竭患者作为研究对象。在患者出院时、出院后 3 个月和 6 个月，采用结构化问卷对其进行采访，评估其身体活动、症状困扰、运动自我效能、焦虑和抑郁、社会支持、睡眠质量和生活质量。
心力衰竭患者的身体活动水平较低，且倾向于久坐。从住院到出院后 6 个月，久坐行为逐渐减少。睡眠质量、生活质量、止痛药使用、症状困扰和运动自我效能是解释 42.1%-51%久坐行为变化的显著相关因素。与低久坐行为组相比，高久坐行为组在住院时的抑郁程度更高，睡眠和生活质量更差，在出院后 3 个月和 6 个月时的抑郁程度显著改善。
心力衰竭患者中久坐行为很常见，会对抑郁和生活质量产生影响。需要为心力衰竭患者制定适当的身体活动计划，重点关注疾病自我管理和增强自我效能感，以改善其久坐行为和生活质量。
