Academic burnout in nursing students is a serious problem worldwide that results in emotional exhaustion, cynicism and low professional efficacy. The aim of the current study was to examine the association between sleep quality and circadian rhythm indicators and academic burnout among Iranian nursing students. This cross-sectional study was conducted on 325 undergraduate nursing students studying at Qazvin University of Medical Sciences between November and February 2023. Data collection was carried out using self-report questionnaires including demographic characteristics, The Pittsburgh Sleep Quality Index (PSQI), reduced-Morningness-Eveningness Questionnaire (r-MEQ), and the Maslach Burnout Inventory-Student Survey (MBI-SS). Social jetlag (SJL) was defined as the absolute value of the difference between the midpoint of sleep on free days (MSF) and the midpoint of sleep on workdays (MSW). Data were analyzed using univariate and multivariate linear regression models. About 31.4% of participants had evening chronotype and almost half of them suffered from poor sleep quality. About 47.7% of the participants had SJL ≥ 2 h. In the multivariate linear regression model, students with evening chronotype compared to morning chronotype experienced more academic burnout in emotional exhaustion, cynicism and professional efficacy. PSQI score was only correlated with emotional exhaustion and cynicism subscales. Increased SJL was a predictor on all three subscales of academic burnout. The findings suggested that evening chronotype, poor sleep quality, and high SJL were associated with increased likelihood of academic burnout in nursing students. Assessment of circadian preference and sleep quality is beneficial for timely identification and prevention of academic burnout in nursing students.
护理专业学生的学业倦怠是一个全球性的严重问题，会导致情绪疲惫、玩世不恭和职业效能感降低。本研究旨在探讨伊朗护理专业学生睡眠质量和昼夜节律指标与学业倦怠之间的关系。这是一项横断面研究，于 2023 年 11 月至 2 月在卡尚医科大学对 325 名护理专业本科生进行。数据收集采用自陈式问卷进行，包括人口统计学特征、匹兹堡睡眠质量指数（PSQI）、简化的早晨-晚上倾向问卷（r-MEQ）和 Maslach 职业倦怠量表-学生版（MBI-SS）。社会时差（SJL）定义为自由日睡眠中点（MSF）和工作日睡眠中点（MSW）之间的差值的绝对值。使用单变量和多变量线性回归模型进行数据分析。大约 31.4%的参与者属于夜间型，几乎一半的人睡眠质量差。大约 47.7%的参与者的 SJL≥2 小时。在多变量线性回归模型中，与早晨型相比，夜间型的学生在情绪疲惫、玩世不恭和职业效能感方面经历更多的学业倦怠。PSQI 评分仅与情绪疲惫和玩世不恭子量表相关。SJL 的增加是学业倦怠所有三个子量表的预测因素。研究结果表明，夜间型、睡眠质量差和高 SJL 与护理学生学业倦怠的可能性增加有关。评估昼夜节律偏好和睡眠质量有利于及时识别和预防护理学生的学业倦怠。
