There is still insufficient data about the characteristics and clinical significance of the bimodal chronotype. We evaluated more than 1000 students with Morningness-Eveningness Questionnaire, Munich Chronotype Questionnaire (MCTQ), Pittsburgh Sleep Quality Index and 36-item Short Form Health Survey. Twelve percent of the sample was bimodal and they showed similar results to intermediate chronotype in MCTQ-chronotype and social jetlag, both different from morning and evening chronotypes. However, their quality of life and sleep quality were similar to evening types, both different from morning and intermediate types. We discuss if being bimodal would be a maladaptive aspect of circadian preference.
关于双峰型昼夜节律类型的特征和临床意义，目前仍缺乏足够的数据。我们使用晨型-夜型问卷、慕尼黑昼夜节律类型问卷（MCTQ）、匹兹堡睡眠质量指数和36项简明健康调查问卷对1000多名学生进行了评估。样本中有12%为双峰型，他们在MCTQ昼夜节律类型和社会时差方面的结果与中间型昼夜节律类型相似，与晨型和夜型昼夜节律类型均不同。然而，他们的生活质量和睡眠质量与夜型相似，与晨型和中间型均不同。我们探讨了双峰型是否会是昼夜节律偏好的一种适应不良表现。
