 Abstract
Purpose: This study was performed to analyze the changes in the 24-hour movement behavior of Korean adolescents during the coronavirus disease 2019 (COVID-19) pandemic, focusing on physical activity (PA) pattern.
Methods: The study used data obtained from the 15th (2019) and 16th (2020) Korea Youth Risk Behavior Survey, targeting a total of 112,251 adolescents. For assessing the changes before and during the pandemic, complex samples cross-tabulation and logistic regression models were used to calculate the odds ratio (OR) and confidence interval (CI).
Results: During the pandemic, as compared to before the pandemic, the rate of male students who met the PA guidelines (a total of 돟60 minutes of moderate-to-vigorous intensity physical activity daily) decreased. The rate of students who met the sedentary behavior (SB) guidelines (recreational SB of <2 hours/day) decreased by about 50%, and there was no significant change in sleep. The OR (95% CI) for students who complied with 24-hour movement behavior guidelines was 0.69 (0.560.85). Conversely, the OR (95% CI) for students who were not compliant with any of the three recommendations was 1.50 (1.411.61). A notable finding is the rate of students who met the vigorous PA (3 days/week) decreased, but the rate of students who met the strength training (3 days/week) increased during the pandemic, which suggests the possibilities for a new trend in PA in the upcoming post-COVID-19 era.
Conclusion: Policymakers should pay attention to changes in movement behaviors observed in adolescents during the pandemic and use the current crisis as an opportunity to respond to the post-COVID-19 era.
