该研究旨在确定中国中小学生在COVID-19大流行期间的健康相关行为（体力活动、屏幕暴露和睡眠状况）水平，以及与大流行前相比的变化。于2020年3月8日至15日，在中国广州的10所学校进行了一项针对10，933名学生的横断面在线调查。在征得学生照顾者的知情同意后，设计了一份在线问卷，并由学生本人或其照顾者填写，以获得在COVID-19大流行期间用于健康相关行为的时间，以及与大流行前3个月相比的变化。学生按地区（城市、郊区、远郊）、性别（男孩和女孩）和年级（小学低年级、小学高年级、中学和高中）分层。数据以数量和百分比表示，组间差异采用卡方检验。总体而言，问卷的回复率为95.3%（10，416/10，933）。纳入学生的中位年龄为13.0（10.0，16.0）岁，50.1%（n = 5，219）为男孩。与疫情前相比，41.4%、53.6%和53.7%的学生报告每天轻度、中度和剧烈活动少于15分钟，58.7%（n = 6，113）的学生报告参加体育活动的时间减少。44.6%（n = 4，649）的受访者报告在线学习的屏幕时间超过5小时，特别是高中生（81.0%）。76.9%的学生报告屏幕时间比大流行前增加。38.5%的学生睡眠不足，高中生的比例最高（56.9%）。我们的研究显示，在COVID-19疫情期间，学校关闭对学龄儿童的健康习惯产生了巨大的负面影响，包括减少体力活动、延长屏幕暴露时间和不规律的睡眠模式。
This study aimed to determine the levels of health-related behaviours (physical activity, screen exposure and sleep status) among Chinese students from primary, secondary and high schools during the pandemic of COVID-19, as well as their changes compared with their status before the pandemic. A cross-sectional online survey of 10,933 students was conducted among 10 schools in Guangzhou, China, between 8th and 15th March, 2020. After getting the informed consent from student’s caregivers, an online questionnaire was designed and used to obtain time spending on health-related behaviours during the pandemic of COVID-19, as well as the changes compared with 3 months before the pandemic, which was completed by students themselves or their caregivers. Students were stratified by regions (urban, suburban, exurban), gender (boys and girls), and grades (lower grades of primary school, higher grades of primary schools, secondary schools and high schools). Data were expressed as number and percentages and Chi-square test was used to analyse difference between groups. Overall, the response rate of questionnaire was 95.3% (10,416/10,933). The median age of included students was 13.0 (10.0, 16.0) years and 50.1% (n = 5,219) were boys. 41.4%, 53.6% and 53.7% of total students reported less than 15 min per day in light, moderate and vigorous activities and 58.7% (n = 6,113) reported decreased participation in physical activity compared with the time before pandemic. Over 5 h of screen time spending on online study was reported by 44.6% (n = 4,649) of respondents, particular among high school students (81.0%). 76.9% of students reported increased screen time compared with the time before pandemic. Inadequate sleep was identified among 38.5% of students and the proportion was highest in high school students (56.9%). Our study indicated that, during the COVID-19 pandemic, the school closure exerted tremendous negative effects on school-aged children’s health habits, including less physical activity, longer screen exposure and irregular sleeping pattern.
