The COVID-19 pandemic has caused changes in health behaviours, including participation in physical activity and screen time. The purpose of this paper is to examine trends in physical activity and screen time among Canadian youth from January 2018 to February 2022.
The Canadian Community Health Survey asks Canadian youth (aged 12 to 17 years) to report the time they spend active by domain: recreation, transportation, school and household. Survey respondents are also asked to report their screen time on school days and non-school days. The present analysis compares the physical activity from four cross-sectional samples collected during 2018 (January to December; n=3,952), January to March 2020 (n=911), September to December 2020 (n=1,573), and January 2021 to February 2022 (n=3,501). Screen time is compared between 2018 and 2021/2022. Sub-annual descriptive analyses examine how physical activity and screen time varied within and between these years.
Before the COVID-19 pandemic, half of Canadian youth met the physical activity recommendation (2018: 49.6%; January to March 2020: 53.7%). The percentage meeting the recommendation dropped in the first year of the pandemic (September to December 2020: 37.3%) and recovered slightly in 2021 (43.8%). From 2018 to 2021, total physical activity dropped by 8.3 minutes per day (58.1 minutes per week) among girls and by 2.1 minutes per day (14.7 minutes per week) among boys. The percentage of youth meeting the screen time recommendation on school days dropped from 40.7% in 2018 to 29.1% in 2021 and from 21.4% in 2018 to 13.2% in 2021 on non-school days.
The COVID-19 pandemic had a detrimental impact on the physical activity and screen time of youth, in particular among girls. This analysis provides an update on how the pandemic has continued to affect the physical activity and screen habits of youth in 2020, 2021, and early 2022.
新冠疫情导致人们的健康行为发生了变化，包括参与体育活动和屏幕时间。本文旨在研究 2018 年 1 月至 2022 年 2 月期间加拿大青少年体育活动和屏幕时间的趋势。
加拿大社区健康调查询问加拿大青少年（12 至 17 岁）在以下领域的活跃时间：娱乐、交通、学校和家庭。调查对象还被问及在上学日和非上学日的屏幕时间。本分析比较了在 2018 年（1 月至 12 月；n=3952）、2020 年 1 月至 3 月（n=911）、2020 年 9 月至 12 月（n=1573）和 2021 年 1 月至 2 月至 2022 年 2 月（n=3501）四个横断面样本中收集的体育活动数据。对 2018 年和 2021/2022 年的屏幕时间进行了比较。年度描述性分析检查了这些年份内和年份间体育活动和屏幕时间的变化情况。
在新冠疫情之前，有一半的加拿大青少年符合体育活动推荐量（2018 年：49.6%；2020 年 1 月至 3 月：53.7%）。疫情第一年（2020 年 9 月至 12 月：37.3%）符合推荐量的比例下降，2021 年略有回升（43.8%）。2018 年至 2021 年期间，女孩的总体育活动量每天减少 8.3 分钟（每周 58.1 分钟），男孩每天减少 2.1 分钟（每周 14.7 分钟）。在上学日，符合屏幕时间推荐量的青少年比例从 2018 年的 40.7%下降到 2021 年的 29.1%，在非上学日，从 2018 年的 21.4%下降到 2021 年的 13.2%。
新冠疫情对青少年的体育活动和屏幕时间产生了不利影响，尤其是对女孩。本分析提供了关于 2020 年、2021 年和 2022 年初疫情如何继续影响青少年体育活动和屏幕习惯的最新情况。
