The widespread use of digital devices among adolescents has raised concerns about the potential impact of screen time on sleep quality. This study aimed to investigate the relationship between screen time and self-reported sleep quality in adolescents.
A cross-sectional study was conducted on adolescents (13- to 19-year-olds) using multi-stage cluster sampling with probability proportional to the size of public schools. Data were collected in November 2022 through self-administered questionnaires. The questionnaire collected sociodemographic characteristics, sleep quality using the Pittsburgh Sleep Quality Index (PSQI), and screen time on weekdays and weekends using the Screen Time Questionnaire (STQ). A scoring system was used in the PSQI and a global score of more than 5 indicates poor sleep quality. The relationship between screen time and sleep quality was analysed using simple and multiple linear regression.
A total of 547 adolescents participated in the study, with a mean (SD) age of 16.66 (1.54) years. The mean (SD) PSQI score was 5.98 (2.70), and 52% of participants had poor sleep quality. The sleep disturbance component had the highest mean (SD) score at 1.35 (0.5) out of a total score of 3.0. The mean (SD) screen time for a weekday was 537.6 (301.5) minutes, and a weekend day was 725.5 (339.2) minutes. The highest median screen time was spent on smartphones during the whole week. A significant linear relationship was observed between age and PSQI global score (p = 0.008), with a 0.2 increase in PSQI global score for each year increase in age (95% CI: 0.05, 0.35). Being female was also significantly associated with a high PSQI global score (p < 0.001). Additionally, a significant linear relationship was observed between screen time on a weekend and PSQI score (p = 0.032).
The study found that half of the adolescents had poor sleep quality, which was associated with being female, increased screen time on weekends, and older age. Future research endeavours should focus on conducting longitudinal studies to assess the temporal relationship between screen time and sleep quality.
青少年广泛使用数字设备引起了人们对屏幕时间对睡眠质量潜在影响的关注。本研究旨在调查青少年的屏幕时间与自我报告的睡眠质量之间的关系。
采用多阶段整群抽样概率与公立学校规模成正比的方法，对 13 至 19 岁的青少年进行横断面研究。数据于 2022 年 11 月通过自填式问卷收集。问卷收集了社会人口统计学特征、使用匹兹堡睡眠质量指数（PSQI）评估的睡眠质量以及工作日和周末使用屏幕时间问卷（STQ）评估的屏幕时间。PSQI 使用评分系统，总分超过 5 分表示睡眠质量差。使用简单和多元线性回归分析屏幕时间与睡眠质量之间的关系。
共有 547 名青少年参与了研究，平均（标准差）年龄为 16.66（1.54）岁。平均（标准差）PSQI 得分为 5.98（2.70），52%的参与者睡眠质量差。睡眠障碍成分的平均（标准差）得分为 1.35（0.5），总分为 3.0。工作日的平均（标准差）屏幕时间为 537.6（301.5）分钟，周末为 725.5（339.2）分钟。整个星期，智能手机的屏幕时间中位数最高。年龄与 PSQI 总分之间存在显著的线性关系（p=0.008），年龄每增加 1 岁，PSQI 总分增加 0.2（95%置信区间：0.05，0.35）。女性也是 PSQI 总分高的显著相关因素（p<0.001）。此外，周末的屏幕时间与 PSQI 评分之间存在显著的线性关系（p=0.032）。
研究发现，一半的青少年睡眠质量差，与女性、周末屏幕时间增加和年龄增长有关。未来的研究应致力于开展纵向研究，评估屏幕时间与睡眠质量之间的时间关系。
