Sleep quality is an important factor in adolescents' health; physical as well as psychological. The aim of this study was to determine sleep quality and daytime sleepiness and their effect on the quality of school life (QSL) and achievement.
This cross-sectional study was conducted in high schools. The data collection was done on a random sample of 500 students from 15 to 19 years. The questionnaires included the Pittsburgh Sleep Quality Index (PSQI) to measure sleep quality and the Epworth Sleepiness Scale to measure daytime sleepiness as well as QSL. Data were analyzed by SPSS 25. Linear and logistic regressions were used to obtain adjusted and unadjusted odds ratios as well as predictors.
The mean PSQI score was 6.2 ± 2.4. It was realized that 377 participants (75.4%) were poor sleepers; 6.2% had excessive daytime sleepiness. There was a significant association between age and quality of sleep ( < 0.04). No association between gender and quality of sleep or between the quality of sleep and school achievement was found. Linear regression exhibited a significant relationship between the quality of sleep and daytime sleepiness (β = 0.218; t = 4.982, = 0.000). There was a significant, inverse correlation between sleepiness and the total score of QSL ( = 0.000). Stepwise linear regression analysis exhibited that daytime sleepiness ( = 0.002) and school achievement ( = 0.001) were predictors of QSL.
According to the study results, sleepiness affects school performance and QSL, and on the other hand, daytime sleepiness is under the effect of sleep quality.
睡眠质量是青少年健康的一个重要因素，包括身体和心理方面。本研究的目的是确定睡眠质量和日间嗜睡情况及其对学校生活质量（QSL）和学业成绩的影响。
本横断面研究在高中进行。对500名15至19岁的学生随机抽样收集数据。问卷包括用于测量睡眠质量的匹兹堡睡眠质量指数（PSQI）、用于测量日间嗜睡情况的爱泼沃斯嗜睡量表以及QSL。数据采用SPSS 25进行分析。使用线性回归和逻辑回归来获得调整和未调整的优势比以及预测因素。
PSQI平均得分为6.2±2.4。结果发现377名参与者（75.4%）睡眠质量差；6.2%有过度日间嗜睡。年龄与睡眠质量之间存在显著关联（<0.04）。未发现性别与睡眠质量之间或睡眠质量与学业成绩之间存在关联。线性回归显示睡眠质量与日间嗜睡之间存在显著关系（β = 0.218；t = 4.982，= 0.000）。嗜睡与QSL总分之间存在显著的负相关（= 0.000）。逐步线性回归分析显示日间嗜睡（= 0.002）和学业成绩（= 0.001）是QSL的预测因素。
根据研究结果，嗜睡会影响学校表现和QSL，另一方面，日间嗜睡受睡眠质量的影响。
