Abstract

b>Background/b>: COVID-19 outbreaks alter most people\'s daily lives and time spent at home has increased. This study aimed to investigate the changes of lifestyle and obesity in Korean adolescents before and during COVID-19 outbreaks. b>Method/b>: We conducted a cross-sectional study of 109,282 Korean boys and girls aged 12?18 years using data from the Korea Youth Risk Behavior online Survey conducted in 2019 and 2020, before and during the pandemic COVID-19, respectively. We compared the prevalence of overweight and obesity, lifestyle variables (diet, exercise, sitting time, and sleep duration), and analyzed the changes in weight and BMI z-scores for each sex and age before and during COVID-19 outbreaks. The adjusted odds ratios (95% confidence intervals) [ORs (95% CIs)] of lifestyle predictors for overweight and obesity with lifestyle were calculated using complex samples multivariate logistic regression analysis. b>Results/b>: The prevalence of overweight and obesity significantly increased from 10% to 10.5% and from 11.5% to 12.7%, respectively. The prevalence of overweight and obesity increased significantly in boys, particularly those under the age of 15, while there were no significant differences in girls, except for those under the age of 12. In boys, the mean BMI z-score increased from 0.28 to 0.39, while in girls, it slightly decreased from 0.07 to 0.04. Fruit consumption, physical activity, and average sleep duration all decreased while average sitting time increased. After controlling for covariates, a short duration of sleep (5.9 hours per day) [ORs (95% CIs): 1.139 (1.083?1.197)] and an increased sitting time (>6.3 hours per day) [1.142 (1.089?1.197)] were significantly associated with an increased risk for overweight/obesity. b>Conclusion/b>: Strategies to improve lifestyle factors linked with the increase in obesity during COVID-19 pandemic are needed at the school and national health service level, as well as health providers.
