目的 我们研究了青少年入睡困难随时间的变化以及与身体活动和屏幕时间行为的关系。方法我们使用了学龄儿童健康行为 (HBSC) 研究 (2002-2006-2010-2014) 的最后四轮调查的数据。我们进行了多级逻辑回归分析，以探讨 33 个欧洲和非欧洲国家的经常性睡眠困难、过度屏幕时间暴露和体力活动不足（即每天 < 60 分钟）之间的关联。 结果 研究结果表明，入睡困难和过度屏幕时间暴露的患病率有所增加，体力活动水平虽小但显着增加。此外，每天看屏幕时间超过 2 小时的青少年出现入睡困难的几率要高出 20%，但没有发现与体力活动存在关联。屏幕时间与入睡困难之间的关联强度随着时间的推移而增强，这可能反映了屏幕时间使用类型的变化（例如，智能手机和平板电脑等易于使用的屏幕的使用增加）。 结论 减少屏幕时间的有效策略是扭转青少年入睡困难不利趋势的关键。
Objectives We examined changes in sleep-onset difficulties over time and associations with physical activity and screen time behavior among adolescents.Methods We used data from last four survey waves of the Health Behavior in School-Aged Children (HBSC) study (2002-2006-2010-2014). Multilevel logistic regression analyses were conducted to explore associations between regular sleeping difficulties, excessive screen time exposure and being insufficiently physically active (i.e., < 60 min daily) among 33 European and non-European countries.Results Findings indicate an increase in the prevalence of sleep-onset difficulties and in excessive screen time exposure and a small but significant increase in physical activity levels. Additionally, adolescents exceeding 2-h daily screen time had 20% higher odds of reporting sleep-onset difficulties, while no association was found for physical activity. The strength of the association between screen time and sleep-onset difficulties increased over time, which may reflect a change in type of screen time use (e.g., the increased use of easy accessible screens such as smartphones and tablets).Conclusions Effective strategies to reduce screen time are key to reverse the detrimental trend in sleep-onset difficulties among adolescents.
