To investigate trend data in the prevalence of sleep-onset difficulties among Norwegian adolescents covering the age groups 11, 13 and 15 years.
Data were based on the Health Behaviour in School-aged Children - A WHO Cross-National Survey (HBSC) - and were collected on six occasions between 1983 and 2005. At each point in time data were obtained from representative samples comprising between 3402 and 5026 adolescents.
The prevalence of sleep-onset difficulties was higher among 11-year-old students compared to the 13- and 15-year-olds. Girls reported a higher prevalence than boys. A logistic regression analysis showed that the prevalence of sleep-onset difficulties overall had increased significantly since 1983, which constituted the reference year. When the analysis was broken down by age and gender, the same tendency was found in all groups.
The prevalence of sleep-onset difficulties among adolescents has increased during the last decades. This development gives reason for concern and should receive more attention from teachers, parents and health professionals.
调查挪威11岁、13岁和15岁青少年入睡困难患病率的趋势数据。
数据基于世界卫生组织跨国调查“学龄儿童健康行为”（HBSC），于1983年至2005年间分六次收集。每次收集时，数据均来自包含3402至5026名青少年的代表性样本。
11岁学生入睡困难的患病率高于13岁和15岁的学生。女孩报告的患病率高于男孩。逻辑回归分析表明，自1983年（作为参考年份）以来，入睡困难的总体患病率显著增加。按年龄和性别细分分析时，所有组均发现相同趋势。
在过去几十年中，青少年入睡困难的患病率有所上升。这一发展令人担忧，应引起教师、家长和健康专业人员更多关注。
