Association of Sleep Duration and Quality of Sleep with Depression in Middle School Students: Based on the Korean Children and Youth Panel Survey

Purpose: The purpose of this study was to examine the relationship between sleep duration, quality of sleep and depression, and to identify the factors associated with depression in middle school students. Methods: This study used a cross-sectional design with secondary data, middle school student panel data from the Korean Children and Youth Panel Survey (2018), and data from a total of 2,590 students was used for analysis. For the statistical analysis, t-test, ANOVA, and hierarchical multiple regression were performed using SPSS ver. 26. Results: The mean depression score in adolescents was 17.99&#x00B1;6.38. Depression had significant differences according to sleep duration and quality. Adolescents with less than eight hours of sleep showed the highest depression, and poor sleepers showed higher depression scores than good sleepers. Gender, school achievement, school satisfaction, economic status, and exercise time were found to significantly relate to depression. After controlling for general characteristics, depression explained 17.2% of the variance in quality of sleep (&#x03B2;=-.15, p<.001) and sleep duration (&#x03B2;=-.04, p=.022). Conclusion: These findings indicate that it is necessary to develop intervention strategies to enhance the quality of sleep and appropriate sleep duration for preventing depression in adolescents.
