摘要

摘要: 目的了解我国四年级学生睡眠量与质的状况及群体差异，探索影响学生睡眠时长和质量的身心因素。方法选取2018年中国教育追踪调查(China education panel survey, CEPS)数据库中重要变量完整的23 717名年龄为10~11岁的学生作为研究对象，分别采用多元线性回归模型和多因素logistic回归分析模型分析具体睡眠时长和自评睡眠质量的身心影响因素。结果我国四年级学生的睡眠时长均值为9.26 h，自评睡眠质量为好的学生占88.56%。BMI分类、生病频率、抑郁程度、吸烟、饮酒、食用烧烤/膨化/西式快餐食品、饮用含糖/碳酸饮料和吃早饭频率会影响睡眠时长(均P < 0.05)。而性别、自评健康等级、生病频率、饮酒、饮用含糖/碳酸饮料和吃早饭是影响学生睡眠质量的因素(均P < 0.05)。结论我国学生中有一部分睡眠平均时长＜10 h，但大部分自评睡眠质量良好，不同的身心因素与健康行为对睡眠时长和睡眠质量的影响效应存在差异化。

Abstract: Objective To understand the status and group differences in sleep quantity and quality among fourth-grade primary school students in China, and to explore its physical and psychological factors. Methods Total of 23 717 school students between the ages of 10 and 11 with complete important variables in the 2018 China Education Panel Survey (CEPS) data were selected as research subjects. A multiple linear regression model was used to analyze factors affecting their sleep duration, and a multifactor logistic regression model was used to analyze factors affecting their sleep quality. Results The average sleep duration of fourth-grade school students nationwide was 9.26 hours, and the proportion of subjects with self-rated good sleep quality was 88.56%. BMI classification, frequency of illness, depression score, smoking, alcohol consumption, consumption of barbecued/puffed/and western fast food, consumption of sugary/carbonated beverages, and the frequency of not eating breakfast were the factors affecting their sleep duration (all P < 0.05). Gender, self-rated health rating, frequency of illness, depressed psychology, alcohol consumption, consumption of barbecued, puffed, and western fast food, and consumption of sugary or carbonated beverages and habits of not eating breakfast were the factors affecting their sleep quality (all P < 0.05). Conclusions The average length of sleep of Chinese fourth-grade primary school students has not reached 10 hours, but the self-assessed sleep quality is good. Different physical and mental factors and health behaviors have different effects on the duration and quality of sleep.
