为了测试澳大利亚和美国青少年在学校夜晚的睡眠时间是否不同，如果是这样，这种差异是否可以通过学校开始时间的文化差异，父母参与设置就寝时间和课外活动来解释。来自澳大利亚的385名13-18岁青少年（M= 15.57，SD =0.95; 60%男性）和来自美国的302名13-19岁青少年（M=16.03，SD=1.19; 35%男性）。青少年在上课时间完成了学校睡眠习惯调查，然后是8天的睡眠日记。在控制了年龄和性别之后，澳大利亚青少年平均每个学校夜晚的睡眠时间比美国青少年多47分钟。澳大利亚青少年更有可能有父母设定的就寝时间（17.5%比6.8%），上学时间更晚（上午8点32分比7点45分），每天花在课外活动上的时间更少（1小时37分钟比2小时41分钟）。父母规定的就寝时间，较晚的学校开始时间，以及花在课外活动上的时间较少的中介因素与更多的总睡眠显着相关。除生物因素外，外在文化因素对青少年睡眠有显著影响。本研究强调了跨文化，生态方法的重要性，以及早期学校开学时间的影响，缺乏父母在就寝时间和课外负荷限制青少年睡眠的限制。
To test whether sleep duration on school nights differs between adolescents in Australia and the U.S. and, if so, whether this difference is explained by cultural differences in school start time, parental involvement in setting bedtimes and extra-curricular commitments. 385 adolescents aged 13-18 years (M=15.57,SD=0.95; 60% male) from Australia and 302 adolescents aged 13-19 years (M=16.03, SD=1.19; 35% male) from the United States. Adolescents completed the School Sleep Habits Survey during class time, followed by an 8-day Sleep Diary. After controlling for age and sex, Australian adolescents obtained an average of 47 minutes more sleep per school night than those in the U.S. Australian adolescents were more likely to have a parent-set bedtime (17.5% vs 6.8%), have a later school start time (8:32am vs 7:45am) and spend less time per day on extra-curricular commitments (1h37m vs 2h41m) than their U.S. peers. The mediating factors of parent-set bedtimes, later school start times, and less time spent on extra-curricular activities were significantly associated with more total sleep. In addition to biological factors, extrinsic cultural factors significantly impact upon adolescent sleep. The present study highlights the importance of a cross-cultural, ecological approach and the impact of early school start times, lack of parental limit setting around bedtimes and extracurricular load in limiting adolescent sleep.
