This study aimed to investigate the changes in physical activity levels and the rate of falls during the COVID-19 pandemic in the Korean population. The Korean Community Health Survey (KCHS) conducted in 2019 was compared with that conducted in 2020. Simple or multiple linear regression with complex sampling was conducted to calculate the estimated value (EV) of physical activity in the 2020 group vs. the 2019 group. The odds ratio (OR) of fall histories was calculated using simple or multiple logistic regression with complex sampling for the 2020 group compared to the 2019 group. The time spent on vigorous and moderate physical activity was lower in the 2020 group than in the 2019 group (EV = -10.0, 95% CI = -12.1 to -8.0, P < 0.001 for vigorous exercise and EV = -24.0, 95% CI = -26.7 to -21.4, P < 0.001 for moderate exercise). The rate of falls was lower in the 2020 group than in the 2019 group (OR = 0.66, 95% CI = 0.62 to 0.70, P < 0.001). Vigorous and moderate exercise decreased after the COVID-19 pandemic compared to before the pandemic. The occurrence of falls was lower during the COVID-19 pandemic than in the pre-pandemic period.
本研究旨在调查韩国人群在 COVID-19 大流行期间体力活动水平和跌倒率的变化。将 2019 年进行的韩国社区健康调查（KCHS）与 2020 年进行的调查进行了比较。采用简单或多元线性回归分析结合复杂抽样方法，计算了 2020 年组与 2019 年组之间体力活动的估计值（EV）。采用简单或多元逻辑回归分析结合复杂抽样方法，计算了 2020 年组与 2019 年组相比的跌倒史的比值比（OR）。与 2019 年组相比，2020 年组剧烈和中度体力活动的时间减少（EV=-10.0，95%CI=-12.1 至-8.0，P<0.001；EV=-24.0，95%CI=-26.7 至-21.4，P<0.001）。与 2019 年组相比，2020 年组的跌倒率较低（OR=0.66，95%CI=0.62 至 0.70，P<0.001）。与大流行前相比，COVID-19 大流行后剧烈和中度运动减少。与大流行前相比，COVID-19 大流行期间跌倒的发生较低。
