The COVID-19 pandemic has dramatically altered daily routines and lifestyle behaviors worldwide, potentially significantly impacting physical activity levels, especially among adolescents. Understanding these changes is crucial for developing targeted interventions to promote health and well-being in this vulnerable population. This paper will explore longitudinal trends of physical activities (PA) in Korean adolescents, focusing on changes between the pre and late-COVID-19 pandemic periods.
The data used were from the Korea Youth Risk Behavior Web-Based Survey for consecutive years from 2009 to 2022. In this study, we have separated data into the pre-COVID-19 pandemic (2009-2019) and the pandemic. Following the World Health Organization (WHO)'s guideline, we analyzed adolescent self-reported moderate-to-vigorous physical activity (MVPA).
A total of 890,941 adolescents, people aged between 12 and 18 years old. The 14-year trends in MVPA showed an upward trend both before the pandemic (β, 0.005; 95 % confidence interval [CI], 0.004-0.005) and during the pandemic (β, 0.004; 0.002-0.006). Furthermore, the prevalence of MVPA recovered/increased in 2022 (5.61 % in 2020, 5.22 % in 2021, and 6.34 % in 2022). Similar to the MVPA patterns, the mean metabolic equivalent task (MET) score increased during before the pandemic (β, 15.392; 12.523-18.261) and during the pandemic (β, 49.518; 41.948-57.088). However, unlike MVPA patterns, the MET slope changed positively (β, 34.126; 26.031-42.221).
Present findings suggest that Korean adolescents achieving the recommended PA levels by the WHO remained steady despite the pandemic. This stability in PA levels during a significant disruption (i.e. the COVID-19 pandemic) is noteworthy and warrants further investigation into the factors that may have contributed to this resilience, including potential influences from various societal and environmental elements.
新冠疫情极大地改变了全球的日常生活和生活方式行为，可能对身体活动水平产生重大影响，尤其是在青少年中。了解这些变化对于制定有针对性的干预措施以促进这一脆弱人群的健康和福祉至关重要。本文将探讨韩国青少年身体活动（PA）的纵向趋势，重点关注新冠疫情前和疫情后期之间的变化。
所使用的数据来自2009年至2022年连续多年的韩国青少年风险行为网络调查。在本研究中，我们将数据分为新冠疫情前（2009 - 2019年）和疫情期间。按照世界卫生组织（WHO）的指南，我们分析了青少年自我报告的中度至剧烈身体活动（MVPA）。
共有890,941名青少年，年龄在12至18岁之间。MVPA的14年趋势在疫情前（β，0.005；95%置信区间[CI]，0.004 - 0.005）和疫情期间（β，0.004；0.002 - 0.006）均呈上升趋势。此外，MVPA的患病率在2022年有所恢复/增加（2020年为5.61%，2021年为5.22%，2022年为6.34%）。与MVPA模式类似，平均代谢当量任务（MET）得分在疫情前（β，15.392；12.523 - 18.261）和疫情期间（β，49.518；41.948 - 57.088）均有所增加。然而，与MVPA模式不同的是，MET斜率呈正向变化（β，34.126；26.031 - 42.221）。
目前的研究结果表明，尽管疫情肆虐，但达到WHO推荐PA水平的韩国青少年人数保持稳定。在重大干扰（即新冠疫情）期间PA水平的这种稳定性值得注意，有必要进一步调查可能促成这种恢复力的因素，包括各种社会和环境因素的潜在影响。
