摘　　要：目的了解香港大学生的睡眠特征。方法研究组为503名自评为健康的香港中文大学在读医科大学生,成年人组为252名自评为健康和非倒班工作者的香港新界小学学生家长。通过Epworth嗜睡量表了解日间困倦程度,通过清晨型/夜晚型量表(MEQ)评价日周期倾向,通过2周睡眠日记确定他们的睡眠习惯。结果在工作日,大学生组的入睡时间和起床时间都晚于成年组,而且睡眠长度短于成年组。在周末,大学生组的入睡时间和起床时间也晚于成年组,两组的入睡时间和周末起床时间均比工作日明显后移,而且大学生组的周末睡眠长度增加比例显著高于成年组。两组的睡眠质量和日间困倦程度没有差别,成年组的MEQ分值明显高于大学生组。结论大学生组比成年组更加倾向于夜晚型,但没有明显的睡眠周期后置症状。大学生组存在明显的工作日睡眠不足,但是并没有感到明显的日间困倦。Objective To investigate the sleep characteristics of university student. Methods This research was composed of two groups： medical college student and adult（ parent of student in primary school）. We learned their sleep behavior by two - week sleep log, assessed their daytime sleepiness by Epworth Sleepiness Scale, and confirmed their circadian preference by Morningness/Eveningness Questionnaire. Results In weekday and weekend, both of bed time and wake time of university students was later than adult. Although adult spent more time in sleeping in weekday, university student spent more time in sleeping in weekend. In addition, they shared similar daytime sleepiness and sleep quality, but university student preferred more eveningness.
