摘要
背景在COVID-19大流行期间,儿童和青少年缺乏体育锻炼(PA)和娱乐屏幕时间(RST)的情况更加严重,导致这一问题升级为一个重要的公共卫生问题。本研究旨在调查 2019 年至 2022 年中国儿童和青少年的 PA 和 RST 的变化趋势,从而分析大流行病对中国儿童和青少年 PA 和 RST 的短期和长期影响。方法在 2019 年至 2022 年期间,每年 9 月至 12 月期间,使用一套统一的问卷对中国小学、初中和高中学生进行全国代表性抽样调查。结果从 2019 年到 2022 年,儿童和青少年的 PA 和 RST 呈倒 U 型趋势,最初上升,随后下降。具体来说,从 2019 年到 2021 年,儿童和青少年的 PA 显著增加,但从 2021 年到 2022 年又急剧下降。这种 PA 趋势在小学、男性、城市和北方儿童与青少年中更为明显。儿童和青少年的 RST 在 2019 年至 2020 年期间有所上升,但在 2020 年至 2022 年期间大幅下降。结论这项研究揭示了大流行病对儿童和青少年活动量和 RST 的影响,表明对活动量的短期有利影响和长期不利影响,以及对 RST 的短期不利影响和长期有利影响。这些发现为在大流行期间制定与儿童和青少年的体育锻炼和体能训练相关的政策奠定了基础。
The effects of COVID-19 on the Physical Activity and Recreational Screen Time among Chinese children and adolescents
Background
The lack of Physical Activity (PA) and prolonged Recreational Screen Time (RST) among children and adolescents has been exacerbated during the COVID-19 pandemic, causing this issue to escalate into a crucial public health concern. This study aims to investigate the trends in PA and RST among Chinese children and adolescents from 2019 to 2022, thereby analyzing the short-term and long-term effects of the pandemic on PA and RST among Chinese children and adolescents.
Methods
A nationally representative sample of Chinese primary, middle, and high school students was surveyed annually between September and December from 2019 to 2022 using a consistent set of questionnaires. Trends in PA and RST across different school levels, genders, areas (urban/rural), and regions (north/south) were analyzed using Segmented Linear Regression.
Results
From 2019 to 2022, the PA and RST of children and adolescents displayed an inverted U-shaped trend, initially increasing and subsequently declining. Specifically, from 2019 to 2021, the PA of children and adolescents significantly increased but dramatically declined from 2021 to 2022. This trend in PA is more pronounced among primary, male, urban, and northern children and adolescent. The RST of children and adolescents increased from 2019 to 2020 but significantly decreased from 2020 to 2022. This trend in RST is more pronounced among primary, urban, and southern children and adolescent.
Conclusions
This research unveils the effects of the pandemic on PA and RST in children and adolescents, suggesting short-term beneficial and long-term adverse effects on PA and short-term adverse and long-term beneficial effects on RST. These findings provide a foundation for formulating policies related to children and adolescents' PA and RST during the pandemic.
