Correlation analysis on sleep duration and academic performance among high school students in Shanghai

摘要

摘要:
目的了解目前高中生的睡眠时间，探讨睡眠时间与学习成绩的相关性，为开展高中生睡眠健康促进提供依据。
方法采用三阶段抽样法抽取上海市28所高中的6 401名高中生，使用《上海市青少年健康相关行为调查问卷(高中版)》进行调查，对调查数据中的睡眠时间和自感学习成绩部分采用Wilcoxon秩和检验、kruskal-Wallis H检验、秩相关、有序logistic逐步回归等方法进行分析。
结果6 401名高中生中，94.8%的学生睡眠时间 < 8 h，其中62.8%的学生 < 7 h。高中生睡眠时间和自感学习成绩的Spearman秩相关系数为0.109，P < 0.01。与睡眠时间 < 7 h的学生相比，睡眠时间≥7 h且 < 8 h和≥8 h的学生自感学习成绩更好，OR值分别为1.42(95%CI:1.29~1.57)和2.04(95%CI:1.65~2.52)。
结论上海市高中生睡眠不足现象严重，而睡眠时间与自感学习成绩呈正相关，对高中生进行促进睡眠健康教育和干预非常必要。
