目的是调查青少年睡眠受限或睡眠不足的发生率、患病率和持续性以及相关危险因素。数据来自基线时 4,175 名 11 至 17 岁青少年的样本，以及 1 年后对 3,134 名青少年进行的随访。睡眠限制被定义为每晚 6 小时或更少。患病率为 20%，1 年发病率为 17%，慢性率为 54%。分析发现了几个独立的预测因素：女性、年龄较大、学业、课外活动和生活压力。对于 8 个或更多因素，工作日夜间睡眠限制发生率的比值比为 10，对于 8 个或更多危险因素持续存在的比值比，为 17。这项前瞻性研究证明睡眠限制的发生率很高。睡眠受限也很普遍且长期存在，并且与许多其他健康问题一样，其根源是多因素的。存在多种风险因素会大大增加睡眠受限的风险。鉴于睡眠在这一人群中的重要性，显然需要在临床和流行病学方面给予更多关注。
The objective is to examine incidence, prevalence, and persistence of restricted or short sleep among adolescents and associated risk factors. Data are from a sample of 4,175 youths aged 11 to 17 at baseline and 3,134 followed up 1 year later. Restricted sleep was defined as 6 hr or less per night. Prevalence was 20%, 1-year incidence was 17%, and chronicity was 54%. Analyses identified few independent predictors: female, older age, schoolwork, extracurricular activities, and life stress. Odds ratios for incidence of sleep restriction on weeknights were 10 for 8 or more factors and 17 for persistence with 8 or more risk factors. This prospective study documents that incidence of sleep restriction was high. Restricted sleep also was prevalent and chronic and, like many other health problems, has multifactorial origins. Having multiple risk factors substantially increased risk of restricted sleep. Given the importance of sleep in this population, more focus is clearly needed, both clinically and epidemiologically.
