Objectives: A majority of South Korean adolescents experience chronic sleep-deprivation due to social jet lag. In this study, we investigated gender differences in the relationship between social jet lag, depression, and obesity in Korean children and adolescents. Methods: Our sample consisted of 4,380 adolescents (elementary school cohort n=2,141, middle school cohort n=2,239) who participated in the Korean Children and Youth Panel Survey. In order to analyze the gender differences in the relationship between sleep time difference, obesity and depression, t-test and chi-square test were utilized. Results: Both cohorts revealed that the difference in weekday/weekend sleep duration (2.19±1.42 vs. 1.68±1.36, p<0.001) and depression levels (20.77±6.29 vs. 18.87±6.06, p<0.001) was significantly higher in girls than boys. However, body mass index was higher in boys than girls (20.86±3.42 vs. 20.04±2.51, p<0.001). Chi-square test revealed there was a significant difference between gender and weekday/weekend sleep discrepancy group (cutoff >2 hours). Both elementary school [χ2 (1)=8.73, p<0.05] and middle school cohorts [χ2 (1)=61.29, p<0.001] showed significant gender d
