Background: The COVID-19 pandemic has disrupted the engagement in 24-hour movement behaviors, namely moderate-to vigorous-physical activity (MVPA), recreational screen time (ST), and sleep (SLP). Objective: To examine the changes in 24-hour movement behaviors pre- and during-COVID-19 pandemic among South Korean adolescents. Methods: Self-reported, population-based data from Korea web-based Youth Risk Behavior Surveys were used (N=112,251). Relative changes in meeting individual and combinations of recommendations within 24-Hour Movement Guidelines between 2019 (pre-COVID-19) and 2020 (during-COVID-19) were calculated. Results: Of 94,624 adolescents (M age: 15.2 years), changes in the adherence to 24-Hour Movement Guidelines pre- and during-COVID-19 were not statistically significant for MVPA (6.1% to 5.8%) and SLP (19.6% to 19.4%); however, a decrease was observed for ST (32.2% to 20.2%, OR: 0.52, 95%CI: 0.51–0.55). Also, a decrease was observed in meeting MVPA+ST (2.3% to 1.5%; OR: 0.62, 95%CI: 0.55–0.69) and ST+SLP (6.3% to 4.0%; OR: 0.63, 95%CI: 0.58–0.67); however, no changes were observed for MVPA+SLP (1.7% to 1.6%). Furthermore, an increase was observed for not meeting any recommendations (51.8% to 61.2%; OR: 1.47, 95%CI: 1.42–1.52) while a decrease was observed for meeting one (39.3% to 32.7%; OR: 0.75, 95%CI: 0.73–0.78), two (8.9% to 6.2%; OR: 0.67, 95% CI: 0.63–0.71), or all (0.7% to 0.5%; OR: 0.67, 95%CI: 0.55–0.82) of the recommendations. Conclusions: Behavioral profile of adolescents has not been ideal in South Korea and this concern is further exacerbated by the COVID-19 pandemic. For recreational pursuits, non-screen-based activities should be encouraged during the pandemic.
