Abstract
This study analyzed the longitudinal relationship between smartphone addiction and sleep duration to investigate the factors contributing to sleep deprivation in Korean children. To overcome the limitations of previous studies, panel quantile regression analysis was used to evaluate the relationship between smartphone addiction and sleep duration. Key variables were smartphone addiction, sleep duration, gender, and age. According to the study results, the level of smartphone addiction among children significantly increased from 2018 to 2022, while sleep duration continuously decreased. A particularly strong negative relationship between smartphone addiction and sleep duration was found. These results suggest that smartphone addiction is strongly associated with sleep deprivation in children, emphasizing the need for policies and intervention measures to create a healthy sleep environment for children.
