청소년의 신체활동과 수면 만족도와의 관련성

Abstract

This study aimed to investigate the relationship between physical activity levels and sleepsatisfaction among Korean adolescents using data from the 2024 Korea Youth Risk BehaviorSurvey. We analyzed raw data from the 2024 Korea Youth Risk Behavior Survey to examinethe association between various types of physical activity and sleep satisfaction amongKorean adolescents. Logistic regression analysis was conducted to assess the relationshipbetween physical activity and sleep satisfaction while controlling for sociodemographicfactors including gender, school level, grade, academic achievement, and householdeconomic status. Korean adolescents demonstrated generally low levels of sleep satisfaction. Sociodemographic analysis revealed that sleep satisfaction was significantly lower amongfemale students compared to male students, decreased with higher school level andgrade, and was inversely associated with academic achievement and household economicstatus. Regardless of the type of physical activity, higher frequency of physical activity wasassociated with greater sleep satisfaction. After controlling for sociodemographic factors,logistic regression analysis confirmed that high-intensity physical activity and resistanceexercise were independently associated with improved sleep satisfaction among adolescents. This study provides evidence that high-intensity physical activity and resistance exercise areindependently associated with better sleep satisfaction among Korean adolescents. Thesefindings offer valuable evidence for developing physical activity policies and programsaimed at promoting sleep health in adolescents. The results emphasize the importance ofincorporating high-intensity physical activity and resistance training into school physicaleducation curricula and youth health promotion programs.
