This study explored the correspondence between adolescents' sleep duration and that of their parents and identified the factors affecting the appropriate sleep duration for adolescents. The data of 795 adolescents from the Korea National Health and Nutrition Examination Survey (2015-2018) were analyzed. We used Cohen's kappa coefficient to measure the correspondence between adolescents' sleep duration and that of their parents. A multiple logistic regression analysis was used to identify the factors affecting adequate sleep duration among adolescents. Our study found that factors such as adolescents' gender, father's education level, and drinking among adolescents and parents influenced the adolescents' sleep duration. Second, a higher correspondence between the sleep duration of adolescents and that of mothers (Kappa = 0.213, p < 0.001) was found compared to that of fathers (Kappa = 0.064, p = 0.031). Finally, an adequate sleep duration among adolescents' mothers was a major factor that influenced the adequate sleep duration of adolescents (OR = 2.494, 95% CI = 1.850-3.362, p < 0.001). Therefore, when organizing adolescent sleep education and management programs in various community sleep management institutions, the main caregiver's sleep duration management and family drinking management should be combined. Additionally, gender equality awareness should be improved for parenting, including monitoring adolescents' sleep accordingly.
