Several recent studies suggested reduced physical activity (PA) related to the COVID-19 pandemic without consensus. This study investigated the changes in PA and sedentary time during the COVID-19 pandemic compared to before the COVID-19 era. The Korea National Health and Nutrition Examination Survey 2019 and 2020 were used. The ≥19-year-old population was examined in 2019 and 2020 for time spent engaging in high- and moderate-intensity PA and sedentary time. Based on the recommended level of PA by the World Health Organization, ≥75 min/wk of high PA and ≥150 min/of moderate PA were classified. A sedentary time of ≥120 min/d was selected. Multiple logistic regression analysis with complex sampling was conducted for ≥75 min/wk of high PA, ≥150 min/wk of moderate PA, and ≥120 min/d of sedentary time in the 2020 group compared to the 2019 group. The ≥75 min/wk high PA was not lower in the 2020 group than in the 2019 group (adjusted odds ratio (aOR) = 0.96, 95% confidence intervals (95% CIs) = 0.79-1.18, P = 0.696). The ≥150 min/wk of moderate PA was also not lower in the 2020 group (aOR = 1.12, 95% CI = 0.94-1.32, = 0.201). However, the ≥150 min/wk of moderate PA in the female group was higher in the 2020 group than in the 2019 group (aOR = 1.29, 95% CI = 1.01-1.65, = 0.042). Sedentary time ≥ 120 min/d was lower in the 2020 group (aOR = 0.35, 95% CI = 0.17-0.72, = 0.005). This association was consistent in the 19-39-year-old and female group. In conclusion, during the COVID-19 pandemic, high and moderate PA were not decreased in Korean adults, while sedentary time was reduced.
最近的几项研究表明，与新冠疫情相关的身体活动（PA）有所减少，但尚未达成共识。本研究调查了新冠疫情期间与新冠疫情之前相比PA和久坐时间的变化。使用了2019年和2020年的韩国国民健康与营养检查调查。2019年和2020年对19岁及以上人群进行了高、中强度PA的时长以及久坐时间的检查。根据世界卫生组织推荐的PA水平，将每周高PA时长≥75分钟和每周中PA时长≥150分钟进行了分类。选择每天久坐时间≥120分钟。对2020年组与2019年组相比，每周高PA时长≥75分钟、每周中PA时长≥150分钟以及每天久坐时间≥120分钟进行了复杂抽样的多因素逻辑回归分析。2020年组每周高PA时长≥75分钟并不低于2019年组（调整后的优势比（aOR）=0.96，95%置信区间（95%CI）=0.79 - 1.18，P = 0.696）。2020年组每周中PA时长≥150分钟也不低于2019年组（aOR = 1.12，95%CI = 0.94 - 1.32，P = 0.201）。然而，2020年组女性每周中PA时长≥150分钟高于2019年组（aOR = 1.29，95%CI = 1.01 - 1.65，P = 0.042）。2020年组每天久坐时间≥120分钟有所降低（aOR = 0.35，95%CI = 0.17 - 0.72，P = 0.005）。这种关联在19 - 39岁人群和女性组中是一致的。总之，在新冠疫情期间，韩国成年人的高、中强度PA并未减少，而久坐时间减少了。
