Exercise self-efficacy is a vital determinant of an individual's active participation in regular exercise, and exercise is a critical component of improving health-related quality of life (HRQOL) in dialysis patients. This study aimed to describe the relationship between exercise self-efficacy and HRQOL in dialysis patients.
A cross-sectional study was conducted in Shanghai, China. Structured questionnaires distributed to the patients collected socio-demographic and disease-related information. Physical activity was assessed by a self-administered questionnaire, and the exercise self-efficacy scale (ESES) was used to measure exercise self-efficacy. HRQOL was evaluated by the kidney disease quality of life instrument-short form version 1.3 (KDQOL-SF™ v1.3). Data were analyzed using a univariate generalized linear model, Spearman correlation, and hierarchical multiple regression.
A positive association was observed between exercise self-efficacy and HRQOL ( = 0.310, < 0.001). Physical activity as a predictor variable explained 9.8% of the variance in overall HRQOL ( < 0.001). Exercise self-efficacy explained an additional 7.1% of the HRQOL variance. In total, 24.6% of the variation in the HRQOL was explained by the socio-demographic variables, disease-related factors, physical activity, and exercise self-efficacy.
Overall, only 16.9% of the change in HRQOL was explained by physical activity and exercise self-efficacy. Future research is still needed to further explore the factors influencing the HRQOL in dialysis patients. However, this finding suggests the need to consider the importance of HRQOL and physical activity as well as exercise self-efficacy when developing intervention programs.
运动自我效能是个体积极参与规律运动的重要决定因素，而运动是改善透析患者健康相关生活质量（HRQOL）的关键组成部分。本研究旨在描述透析患者运动自我效能与HRQOL之间的关系。
在中国上海进行了一项横断面研究。向患者发放的结构化问卷收集了社会人口统计学和疾病相关信息。通过自我管理问卷评估身体活动情况，并使用运动自我效能量表（ESES）来测量运动自我效能。采用肾病生活质量简表1.3版（KDQOL-SF™ v1.3）评估HRQOL。使用单变量广义线性模型、Spearman相关性分析和分层多元回归分析数据。
观察到运动自我效能与HRQOL之间存在正相关（ = 0.310， < 0.001）。作为预测变量的身体活动解释了总体HRQOL中9.8%的方差（ < 0.001）。运动自我效能又额外解释了HRQOL方差的7.1%。社会人口统计学变量、疾病相关因素、身体活动和运动自我效能总共解释了HRQOL中24.6%的变异。
总体而言，身体活动和运动自我效能仅解释了HRQOL变化的16.9%。未来仍需进一步研究以探索影响透析患者HRQOL的因素。然而，这一发现表明在制定干预方案时需要考虑HRQOL、身体活动以及运动自我效能的重要性。
