目的/背景：睡眠在维持健康和认知方面起着核心作用。在大多数流行病学研究中，睡眠是通过自我报告问卷进行评估的，但有几份报告表明，这些评估可能不如多导睡眠图或活动记录仪等客观指标那么准确。客观和主观测量之间差异的决定因素仍有待调查。这项先导性研究的目的是检验情绪状态在确定老年人睡眠时间的客观和主观测量之间的差异中所起的作用。患者/方法：通过活动记录仪记录45名老年人至少连续三个晚上的客观睡眠数量和质量。主观睡眠时间和辅助数据，如情绪状态和记忆，使用生态瞬时评估进行评估。结果：生态瞬时评估与活动睡眠时间测量结果有显著差异(p<；0.001)。这种差异的大小是由患者的情绪状况解释的(p=0.020)。没有发现这种差异的大小与年龄、性别、睡眠质量或记忆表现之间的关系。结论：经典的睡眠持续时间客观和主观测量之间的差异可以用醒来时的情绪状态来解释。这些结果对流行病学和临床研究具有潜在的意义，这些研究将睡眠作为发病率或死亡率的风险因素。
Objective/Background: Sleep plays a central role in maintaining health and cognition. In most epidemiologic studies, sleep is evaluated by self-report questionnaires but several reports suggest that these evaluations might be less accurate than objective measures such as polysomnography or actigraphy. Determinants of the discrepancy between objective and subjective measures remain to be investigated. The aim of this pilot-study was to examine the role of mood states in determining the discrepancy observed between objective and subjective measures of sleep duration in older adults.Patients/Methods: Objective sleep quantity and quality were recorded by actigraphy in a sample of 45 elderly subjects over at least three consecutive nights. Subjective sleep duration and supplementary data, such as mood status and memory, were evaluated using ecological momentary assessment (EMA).Results: A significant discrepancy was observed between EMA and actigraphic measures of sleep duration (p < 0.001). The magnitude of this difference was explained by the patients mood status (p = 0.020). No association was found between the magnitude of this discrepancy and age, sex, sleep quality or memory performance.Conclusion: The discrepancy classically observed between objective and subjective measures of sleep duration can be explained by mood status at the time of awakening. These results have potential implications for epidemiologic and clinical studies examining sleep as a risk factor for morbidity or mortality.
