We aimed to investigate school-aged students' physical activity behaviors and overweight status during the COVID-19 quarantine.
In this cross-sectional study, an online questionnaire was utilized to measure participants' physical activity behavior and overweight status during the COVID-19 quarantine in Iran (May of 2021). Participants self-reported their physical activity levels, types, amounts and locations, as well as whether or not they became overweight. The chi-square test was used to determine the differences in the distribution of the participant responses. The statistical significance level was set at <0.05.
The questionnaire was completed by 43,660 school-aged students (15,532 boys and 28,128 girls). The age, weight, and height ranges were 8-17 yr, 18-144 kg, and 75-198 cm respectively. Half of the students reported changes in their body weight and became overweight during the COVID-19 pandemic (χ=25514.4; =0.001). Forty-one percent reported doing very little or no physical activity, 32% of students reported doing less than one hour of exercise per day (χ2=8547.7; =0.001). The majority of students (72%) reported participating in physical activity at home (χ2=78851.2; =0.001). Flexibility was the main kind of exercise performed, followed by walking or running, during the COVID-19 pandemic (χ2=24328.9; =0.001).
During the COVID-19 pandemic, half of the students became overweight, and the majority did not engage in regular physical activity. These findings can help guide efforts to protect and promote children's health during the COVID-19 outbreak, as well as influence policies to reduce the risk of future pandemics.
我们旨在调查新冠疫情隔离期间学龄学生的身体活动行为及超重状况。
在这项横断面研究中，采用在线问卷来测量伊朗（2021年5月）新冠疫情隔离期间参与者的身体活动行为及超重状况。参与者自行报告其身体活动水平、类型、量及地点，以及他们是否超重。采用卡方检验来确定参与者回答分布的差异。统计学显著性水平设定为<0.05。
43660名学龄学生（15532名男生和28128名女生）完成了问卷。年龄、体重和身高范围分别为8至17岁、18至144千克和75至198厘米。一半的学生报告称在新冠疫情期间体重发生变化并超重（χ=25514.4；=0.001）。41%的学生报告几乎没有或完全没有进行身体活动，32%的学生报告每天锻炼不足一小时（χ2=8547.7；=0.001）。大多数学生（72%）报告在家中进行身体活动（χ2=78851.2；=0.001）。在新冠疫情期间，柔韧性运动是主要的锻炼类型，其次是步行或跑步（χ2=24328.9；=0.001）。
在新冠疫情期间，一半的学生超重，且大多数学生未进行规律的身体活动。这些发现有助于指导在新冠疫情爆发期间保护和促进儿童健康方面的努力，以及影响降低未来大流行风险的政策。
