Adequate sleep is critical for adolescents' physical and mental health. However, academic demands and lifestyle habits lead to insufficient sleep among many adolescents. This study examined the relationship between sleep patterns and general characteristics, health behaviors, and mental health among South Korean adolescents. Data were obtained from the Korea Youth Risk Behavior Survey conducted by the Korea Disease Control and Prevention Agency, involving 21,283 students aged between 13 and 18 years. Self-reported sleep duration was categorized as adequate (8-10 h) or insufficient (less than 8 h on both weekdays and weekends), and 20 independent variables across demographic, socioeconomic, lifestyle, health-related behavioral, and psychological factors were analyzed. Multiple logistic regression analyses were conducted to evaluate the effects of insufficient sleep. Insufficient sleep was more prevalent among female students (odds ratio [OR]: 2.064) and older students (OR: 16.588 for Grade 12 vs. Grade 7) and was associated with higher stress levels (OR: 4.338 for almost always vs. never), suicidal ideation (OR: 1.826), and unhealthy behaviors such as alcohol consumption (OR: 2.009), smoking (OR: 1.998), and smartphone overdependence (OR: 2.313 for severe vs. normal). In contrast, adolescents with adequate sleep reported greater happiness (OR: 4.167 for very much vs. not at all) and better academic performance (OR: 1.377 for very high vs. very low). The findings show that insufficient sleep significantly affects adolescent well-being, highlighting the need for tailored interventions and increased societal awareness. Future research should explore the mechanisms underlying gender differences and weekday-weekend sleep disparities to enhance sleep quality in this population.
充足的睡眠对青少年的身心健康至关重要。然而，学业要求和生活方式习惯导致许多青少年睡眠不足。本研究调查了韩国青少年的睡眠模式与一般特征、健康行为和心理健康之间的关系。数据来自韩国疾病控制与预防机构进行的韩国青少年风险行为调查，涉及21283名13至18岁的学生。自我报告的睡眠时间分为充足（8 - 10小时）或不足（工作日和周末均少于8小时），并分析了20个涵盖人口统计学、社会经济、生活方式、健康相关行为和心理因素的独立变量。进行了多项逻辑回归分析以评估睡眠不足的影响。睡眠不足在女学生（优势比[OR]：2.064）和年龄较大的学生（12年级与7年级相比，OR：16.588）中更为普遍，并且与较高的压力水平（几乎总是与从不相比，OR：4.338）、自杀意念（OR：1.826）以及饮酒（OR：2.009）、吸烟（OR：1.998）和智能手机过度依赖（严重与正常相比，OR：2.313）等不健康行为相关。相比之下，睡眠充足的青少年报告有更高的幸福感（非常幸福与完全不幸福相比，OR：4.167）和更好的学业成绩（非常高与非常低相比，OR：1.377）。研究结果表明，睡眠不足会显著影响青少年的幸福感，凸显了进行针对性干预和提高社会意识的必要性。未来的研究应探索性别差异和工作日 - 周末睡眠差异背后的机制，以提高该人群的睡眠质量。
