AIM The aim of this study was to describe sleep habits and sleep problems in a population of undergraduates in Palestine. Association between self-reported sleep quality and self-reported academic achievement was also investigated. METHODS Sleep habits and problems were investigated using a convenience sample of students from An-Najah National University, Palestine. The study was carried out during spring semester, 2009. A self-administered questionnaire developed based on The Diagnostic and Statistical Manual of Mental Disorders IV criteria and Pittsburgh Sleep Quality Index was used. RESULTS 400 students with a mean age of 20.2 ± 1.3 were studied. Reported mean duration of night sleep in the study sample was 6.4 ± 1.1 hours. The majority (58.3%) of students went to bed before midnight and 18% of the total sample woke up before 6 am. Sleep latency of more than one hour was present in 19.3% of the students. Two thirds (64.8%) of the students reported having at least one nocturnal awakening per night. Nightmares were the most common parasomnia reported by students. Daytime naps were common and reported in 74.5% of the study sample. Sleep quality was reported as "poor" in only 9.8% and was significantly associated with sleep latency, frequency of nocturnal awakenings, time of going to bed, nightmares but not with academic achievement. CONCLUSION Sleep habits among Palestinian undergraduates were comparable to those reported in European studies. Sleep problems were common and there was no significant association between sleep quality and academic achievement.

巴勒斯坦学生的睡眠习惯和睡眠问题。

目的 本研究的目的是描述巴勒斯坦本科生的睡眠习惯和睡眠问题。还调查了自我报告的睡眠质量和自我报告的学业成绩之间的关联。方法 使用来自巴勒斯坦 An-Najah 国立大学的学生的便利样本调查睡眠习惯和问题。该研究是在 2009 年春季学期进行的。使用基于精神疾病诊断和统计手册 IV 标准和匹兹堡睡眠质量指数开发的自我管理问卷。结果 研究了 400 名平均年龄为 20.2 ± 1.3 岁的学生。研究样本中报告的平均夜间睡眠时间为 6.4 ± 1.1 小时。大多数 (58.3%) 的学生在午夜前睡觉，总样本的 18% 在早上 6 点前起床。19.3% 的学生存在超过 1 小时的睡眠潜伏期。三分之二 (64.8%) 的学生报告说每晚至少有一次夜醒。噩梦是学生报告的最常见的异睡症。74.5% 的研究样本报告了白天小睡很常见。仅 9.8% 的睡眠质量被报告为“差”，并且与睡眠潜伏期、夜醒频率、就寝时间、噩梦显着相关，但与学业成绩无关。结论 巴勒斯坦本科生的睡眠习惯与欧洲研究报告的相当。睡眠问题很常见，睡眠质量与学业成绩之间没有显着关联。8%) 的学生报告说每晚至少有一次夜醒。噩梦是学生报告的最常见的异睡症。74.5% 的研究样本报告了白天小睡很常见。仅 9.8% 的睡眠质量被报告为“差”，并且与睡眠潜伏期、夜间觉醒频率、就寝时间、噩梦显着相关，但与学业成绩无关。结论 巴勒斯坦本科生的睡眠习惯与欧洲研究报告的相当。睡眠问题很常见，睡眠质量与学业成绩之间没有显着关联。8%) 的学生报告说每晚至少有一次夜醒。噩梦是学生报告的最常见的异睡症。74.5% 的研究样本报告了白天小睡很常见。仅 9.8% 的睡眠质量被报告为“差”，并且与睡眠潜伏期、夜醒频率、就寝时间、噩梦显着相关，但与学业成绩无关。结论 巴勒斯坦本科生的睡眠习惯与欧洲研究报告的相当。睡眠问题很常见，睡眠质量与学业成绩之间没有显着关联。仅 9.8% 的睡眠质量被报告为“差”，并且与睡眠潜伏期、夜醒频率、就寝时间、噩梦显着相关，但与学业成绩无关。结论 巴勒斯坦本科生的睡眠习惯与欧洲研究报告的睡眠习惯相当。睡眠问题很常见，睡眠质量和学业成绩之间没有显着关联。仅 9.8% 的睡眠质量被报告为“差”，并且与睡眠潜伏期、夜醒频率、就寝时间、噩梦显着相关，但与学业成绩无关。结论 巴勒斯坦本科生的睡眠习惯与欧洲研究报告的相当。睡眠问题很常见，睡眠质量和学业成绩之间没有显着关联。
