Abstract:
Background:This study examined the factors influencing non-academic sedentary behavior among Korean adolescents, focusing on weekday–weekend differences.
Methods:A secondary analysis was conducted using data from the 2023 Korea Youth Risk Behavior Survey (N=52,880). Sedentary behavior was measured separately on weekdays and weekends. Independent variables included sex, age, and body mass index (BMI; physical characteristics); stress, anxiety, and smartphone overdependence (psychological characteristics); and living with family (social characteristics). Data were analyzed using complex sample general linear models.
Results:Average sedentary time was 206.35 minutes on weekdays and 321.96 minutes on weekends. Sex, age, BMI, anxiety, and smartphone overdependence significantly predicted sedentary behavior on both weekdays and weekends (P<0.05). Stress was significant only on weekends (P=0.012); living with family showed no significant association.
Conclusions:Psychological and behavioral factors substantially influence adolescents’ sedentary behavior. In particular, smartphone overdependence and anxiety should be considered, and interventions need to address emotional and contextual factors, including weekday–weekend differences.
