Background
Poor sleep quality and internet addiction are significant issues affecting adolescents globally, and Nepal is no exception. Several studies have independently assessed the prevalence and associated factors of poor sleep quality and internet addiction among Nepali adolescents and youth, but the relationship between sleep-related attributes and internet addiction remains unexplored. This study aimed to explore the prevalence and contributing factors of poor sleep quality and internet addiction along with the relationship between sleep quality-related attributes and internet addiction.
Material and methods
A cross-sectional study was conducted among 243 adolescents of Dakshinkali Municipality, Nepal. Pittsburgh Sleep Quality Index and Young’s Internet Addiction Test scale were used to measure sleep quality and internet addiction. Pearson’s chi-square test and binary logistic regression were performed at a 5% level of significance to examine the associated factors.
Results
The prevalence of poor sleep quality was 27.6% (95% CI: 22.6–33.7) while potential internet addiction was 49.4% (95% CI: 42.0–56.7). Poor sleep quality was associated with internet addiction (aOR: 1.845; 95% CI: 1.344–3.608), poor perceived relation with teachers (aOR: 2.274; 95% CI: 1.149–4.497), and presence of family conflict (aOR: 2.355; 95% CI: 1.040–5.329). Bad subjective sleep quality (aOR: 5.613; 95% CI: 2.007–15.701), sleep disturbance (aOR: 1.781; 95% CI: 1.251–4.872), frequent daytime dysfunction (aOR: 1.902; 95% CI: 1.083–4.638), and poor perceived relation with teachers (aOR: 2.298; 95% CI: 1.233–4.285), and presence of family conflict (aOR: 1.606; 95% CI: 1.202–3.675) were associated with internet addiction.
Conclusion
Almost a quarter of adolescents’ experience poor sleep quality, while nearly half screened positive for potential internet addiction. Established interrelations between sleep quality and internet usage underscore the importance of integrated intervention approaches combining lifestyle modification and family/school support to protect and promote the mental health and well-being of Nepalese adolescents.

背景
全球范围内，睡眠质量不佳与网络成瘾均为影响青少年群体的重要公共卫生问题，尼泊尔亦不例外。既往已有多项研究分别针对尼泊尔青少年与青年群体的睡眠质量不佳、网络成瘾的流行现状及相关影响因素展开评估，但睡眠相关特征与网络成瘾之间的关联仍未被探索。本研究旨在探讨睡眠质量不佳与网络成瘾的流行情况及影响因素，并分析睡眠质量相关特征与网络成瘾之间的关联。
材料与方法
本研究在尼泊尔达克辛卡利市（Dakshinkali Municipality）的243名青少年中开展横断面研究。采用匹兹堡睡眠质量指数（Pittsburgh Sleep Quality Index）与杨氏网络成瘾量表（Young’s Internet Addiction Test）分别评估睡眠质量与网络成瘾程度。以5%为显著性水平，采用皮尔逊卡方检验（Pearson’s chi-square test）与二元logistic回归（binary logistic regression）分析相关影响因素。
结果
睡眠质量不佳的检出率为27.6%（95%置信区间：22.6~33.7），潜在网络成瘾检出率为49.4%（95%置信区间：42.0~56.7）。睡眠质量不佳与网络成瘾（调整后比值比（adjusted Odds Ratio，aOR）：1.845；95%置信区间：1.344~3.608）、与教师关系感知不佳（aOR：2.274；95%置信区间：1.149~4.497）及家庭冲突存在（aOR：2.355；95%置信区间：1.040~5.329）显著相关。主观睡眠质量差（aOR：5.613；95%置信区间：2.007~15.701）、睡眠障碍（aOR：1.781；95%置信区间：1.251~4.872）、频繁日间功能障碍（aOR：1.902；95%置信区间：1.083~4.638）、与教师关系感知不佳（aOR：2.298；95%置信区间：1.233~4.285）及家庭冲突存在（aOR：1.606；95%置信区间：1.202~3.675）均与网络成瘾显著相关。
结论
近四分之一的青少年存在睡眠质量不佳问题，近半数青少年筛查为潜在网络成瘾阳性。睡眠质量与网络使用之间已明确的关联，凸显了结合生活方式调整、家庭与学校支持的综合干预方案，对维护和促进尼泊尔青少年心理健康与福祉的重要性。
