This study aims to examine the association between the chronotype (morningness/eveningness) and specific mental disorders.
Cross-sectional epidemiological study conducted in three in-patient clinical settings. A total of 1468 consecutive in-patients who gave their written consent were enrolled. On the admission day, patients filled sleep questionnaires and a nurse filled a Clinical Global Impressions scale. Hospitalization reports and ICD-10 diagnoses were collected.
Sleep/wake schedule was similar between the psychiatric diagnoses. On the other hand, morning type patients had an earlier bedtime, earlier wakeup time and shorter sleep duration than the other chronotype regardless of the diagnosis. In multivariate models, patients with a depressive disorder or a psychosis were more likely to be morning type. Patients with an anxiety disorder, addiction disorder or personality disorder were more likely to be evening type.
Age and sleep/wake schedule are contributing factors for the chronotype but mental disorders too appeared to modulate chronotype preferences.
本研究旨在探讨时型（早起型/晚起型）与特定精神障碍之间的关联。
在三个住院临床环境中进行横断面流行病学研究。共纳入 1468 名连续住院并书面同意参加的患者。在入院当天，患者填写睡眠问卷，护士填写临床总体印象量表。收集住院报告和 ICD-10 诊断。
精神科诊断之间的睡眠/觉醒时间表相似。另一方面，无论诊断如何，早起型患者的就寝时间更早、醒来时间更早、睡眠时间更短。在多变量模型中，患有抑郁症或精神病的患者更可能是早起型。患有焦虑症、物质使用障碍或人格障碍的患者更可能是晚起型。
年龄和睡眠/觉醒时间表是时型的影响因素，但精神障碍似乎也调节了时型偏好。
