Abstract

Background: 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. Method: 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. Results: 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
