研究目的：研究目的：探讨香港青少年的睡眠-觉醒模式，评估其睡眠障碍状况，找出与睡眠障碍有关的因素，并探讨睡眠-觉醒变量与学习成绩的关系。采用自陈式问卷调查，包括睡眠-觉醒习惯问卷、睡眠质量指数、晨性/夜性量表、埃普沃思嗜睡量表、知觉压力量表、学习成绩和个人资料。平均上学时间为23：24，总睡眠时间为7.3小时，周末平均就寝时间和起床时间分别延迟64分钟和195分钟。在过去3个月内每周发生3天睡眠障碍的患病率为：入睡困难（5.6%），夜间醒来（7.2%）和早晨过早醒来（10.4%）。这三种症状中≥ 1种的患病率为19.1%。逐步回归分析显示，昼夜节律相位偏好是最重要的预测学校晚上就寝时间，周末睡过头，白天嗜睡。感知压力是睡眠障碍的最重要的危险因素。边缘的学习成绩的学生报告后bedtimes和较短的睡眠在上学的夜晚，更大的周末延迟就寝时间，更多的白天嗜睡比那些成绩较好的。结论：香港青少年的睡眠剥夺和睡眠障碍的患病率是在其他国家发现的。应考虑对青少年睡眠问题进行干预。
Study objectives: To determine sleep-wake patterns and evaluate sleep disturbance in Hong Kong adolescents; to identify factors that are associated with sleep disturbance; and to examine the relationship of sleep-wake variables and academic performance.Design and Setting: A school-based cross-sectional survey.Participants: Sample included 1629 adolescents aged 12 to 19 years.Measurements and Results: Self-report questionnaires, including sleep-wake habit questionnaire, Sleep Quality Index, Morningness/ Eveningness scale, Epworth Sleepiness Scale, Perceived Stress Scale, academic performance, and personal data were administered. The average school-night bedtime was 23:24, and total sleep time was 7.3 hr. During weekends, the average bedtime and rise time was delayed by 64 min and 195 min, respectively. The prevalence of sleep disturbances occurring 3 days per week in the preceding 3 months were: difficulty falling asleep (5.6%), waking up during the night (7.2%), and waking up too early in the morning (10.4%). The prevalence of >= 1 of these three symptoms was 19.1%. Stepwise regression analyses revealed that circadian phase preference was the most significant predictor for school night bedtime, weekend oversleep, and daytime sleepiness. Perceived stress was the most significant risk factor for sleep disturbance. Students with marginal academic performance reported later bedtimes and shorter sleep during school nights, greater weekend delays in bedtime, and more daytime sleepiness than those with better grades.Conclusion: The prevalence of sleep deprivation and sleep disturbance among Hong Kong adolescents is comparable to those found in other countries. An intervention program for sleep problems in adolescents should be considered.
