Longer sedentary time and insufficient sleep are common and potentially serious problems among adolescents and have substantially adverse effects on their physical and mental health. In this school-based study, we conducted an ecological momentary assessment using actigraphy to examine the within-subject association between sedentary time and sleep duration among 80 Korean adolescents aged 12-17. Objectively measured sedentary time and sleep duration were recorded over 5 days; participants also completed a self-reported questionnaire and sleep logs. Using a generalized estimating equation, analysis revealed that daily sedentary time was significantly and negatively associated with sleep duration (β = -.36, = .028). Additionally, the interaction between age and sedentary time significantly affected sleep duration (β = .03, = .012). These findings suggest the need for school-based interventions that aim to reduce sedentary time and thereby improve sleep duration, helping adolescents, especially younger ones, to achieve a healthier lifestyle.
长时间久坐和睡眠不足在青少年中很常见，也是潜在的严重问题，对他们的身心健康有很大的不利影响。在这项基于学校的研究中，我们使用活动记录仪进行了一项生态瞬间评估，以检查 80 名 12-17 岁韩国青少年的久坐时间和睡眠时间之间的个体内关联。客观测量的久坐时间和睡眠时间记录了 5 天；参与者还完成了一份自我报告问卷和睡眠日志。使用广义估计方程分析表明，每天的久坐时间与睡眠时间呈显著负相关（β=-.36，=.028）。此外，年龄和久坐时间之间的交互作用对睡眠持续时间有显著影响（β=.03，=.012）。这些发现表明需要开展基于学校的干预措施，旨在减少久坐时间，从而改善睡眠时间，帮助青少年，特别是年龄较小的青少年，实现更健康的生活方式。
