Abstract：
OBJECTIVE: This study aimed to investigate the association between adherence to 24-h movement guidelines and metabolic syndrome (MetS) before and during the COVID-19 pandemic.
METHODS: Repeated cross-sectional design.
METHODS: We selected 10,882 adults (2019: n = 5710; 2020: n = 5172) aged ≥20 years from the Korea National Health and Nutrition Examination Survey. Domain-specific physical activity and sedentary behavior were assessed using a global physical activity questionnaire. We also measured the typical sleep duration (h/day) on weekdays and weekends. MetS was defined as the presence of more than three risk factors.
RESULTS: During the COVID-19 pandemic, transportation-related physical activity decreased, while the prevalence of abdominal obesity (+3.3 %) and low HDL-C levels (+3.1 %) increased significantly. An elevated risk of MetS was observed in the lower aerobic (odds ratio [OR], 1.28; 95% confidence interval [CI], 1.04-1.58; P = 0.019) and muscular exercise (OR, 1.31; 95% CI, 1.04-1.66; P = 0.023) groups and in the high sedentary behavior (OR, 1.23; 95% CI, 1.00-1.51; P = 0.049) during the pandemic. Sensitivity analysis stratified by sex showed similar patterns with more pronounced changes in MetS components in males. The models also showed significant associations between aerobic physical activity, strength exercises, and sedentary behavior with MetS in males and females.
CONCLUSIONS: Although sedentary behavior and sleep time remained unchanged, a significant decrease in transportation-related physical activity was observed during the pandemic. Moreover, our findings revealed that aerobic physical activity, strength exercise, and sedentary time during the pandemic were associated with an increased MetS risk. These results highlight the importance of promoting physical activity, particularly during periods of social restriction, to mitigate the pandemic\'s negative effects on metabolic health.

摘要：
目的：本研究旨在调查COVID-19大流行之前和期间遵守24小时运动指南与代谢综合征（MetS）之间的关系。
方法：重复横截面设计。
方法：我们从韩国国家健康和营养检查调查中选择了10,882名年龄≥20岁的成年人（2019年：n=5710；2020年：n=5172）。使用全球体力活动问卷评估特定领域的体力活动和久坐行为。我们还测量了工作日和周末的典型睡眠持续时间(h/天)。MetS被定义为存在三个以上的危险因素。
结果：在COVID-19大流行期间，与交通相关的身体活动减少，而腹型肥胖(+3.3%)和低HDL-C水平(+3.1%)的患病率显著增加.在较低的有氧运动中观察到MetS的风险升高(比值比[OR]，1.28；95%置信区间[CI]，1.04-1.58；P=0.019）和肌肉运动（OR，1.31；95%CI，1.04-1.66；P=0.023)组和高久坐行为(OR，1.23；95%CI，1.00-1.51；P=0.049)。按性别分层的敏感性分析显示出相似的模式，男性的MetS成分变化更为明显。这些模型还显示了有氧体力活动之间的显著关联，力量练习,男性和女性与MetS的久坐行为。
结论：尽管久坐行为和睡眠时间保持不变，大流行期间,与交通相关的体力活动显著减少.此外，我们的发现揭示了有氧运动，力量锻炼,大流行期间久坐时间与MetS风险增加相关.这些结果突出了促进身体活动的重要性,特别是在社会限制时期，以减轻大流行对代谢健康的负面影响。
