Abstract: Objective: To explore the latent class of self -regulated fatigue in maintenance hemodialysis patients, and analyze its influencing factors. Methods: A total of 244 maintenance hemodialysis patients were conveniently selected from March 2022 to March 2023, and a general information questionnaire and a self-regulated fatigue scale were used in the survey. Latent class analysis was used to classify self-regulated fatigue in maintenance hemodialysis patients, and multiple logistic regression analysis was used to explore the impact of various influencing factors on their different categories. Results: The self-regulated fatigue score of maintenance hemodialysis patients was (52.27±9.47) points. Maintenance hemodialysis patients were divided into high emotional control group (40.0%), high cognitive-behavioral control group (27.0%), and high regulatory fatigue group (33.0%). The results of multiple logistic regression analysis showed that gender, educational level, dialysis time, and weekly dialysis frequency were predictive factors for the potential category of self-regulated fatigue in maintenance hemodialysis patients (P<0.05). Conclusion: There are three latent class of self-regulated fatigue in maintenance hemodialysis patients. Medical personnel should pay attention to different characteristic populations and adopt targeted intervention measures to enhance patients′ cognitive, emotional, and behavioral regulation abilities from multiple aspects, and improve their self-regulation level.

摘要： 目的：探讨维持性血液透析患者自我调节疲劳的潜在类别并分析其影响因素。方法：便利选取 2022 年 3 月至 2023 年 3 月244 例维持性血液透析患者为研究对象，采用一般资料调查表、自我调节疲劳量表对其进行调查。采用潜在类别分析对维持性血液透析患者自我调节疲劳进行分类，多元 logistic 回归分析探讨各影响因素对其不同类别的影响。结果：244 例维持性血液透析患者自我调节疲劳得分为（52.27±9.47）分。潜在类别分析显示，维持性血液透析患者自我调节疲劳可分为高情绪控制组（40.0%）、高 认知-行为控制组（27.0%）、高调节疲劳组（33.0%）3 个潜在类别。多元 logistic 回归分析结果显示，性别、文化程度、透析时间、每周透析次数是维持性血液透析患者自我调节疲劳潜在类别的预测因素（P<0.05）。结论：维持性血液透析患者自我调节疲劳存在 3 个潜在类别。医务人员应关注不同特征人群，采取有针对性的干预措施，提升患者认知、情绪、行为调节能力，提高其自我调节水平。
