This study aimed to examine the association between sleep duration, stress levels, and dietary behavior inadolescents. A survey was conducted on 453 students (227 male, 226 female) in high schools in the Chungbukarea. The participants were divided into groups based on daily sleep duration: group I (＜5 hrs/d), group II(≥5 hrs/d and ＜6 hrs/d), group III (≥6 hrs/d and ＜7 hrs/d), and group IV (≥7 hrs/d). To measure thestress levels of participants, the survey had questions covering a variety of areas, including school life, familylife, social relationships, and personal evaluation. To assess the dietary behaviors of participants, the surveyincluded questions encompassing the Nutrition Quotient for Korean adolescents (NQ-A). Among female students,the sleep duration group IV had significantly lower total stress (P=0.022) and significantly lower stressin the personal evaluation area than the sleep duration group I (P=0.004). In the analysis of NQ-A, amongfemale students, the sleep duration group IV showed significantly higher scores in balance (P=0.004), diversity(P=0.016), and total NQ-A score area (P=0.007) compared to other groups. There was a significant negativecorrelation between sleep duration and stress scores in total students (r=?0.24, P＜0.001), while a significantpositive correlation was seen between sleep duration and NQ-A scores in female students (r=0.16, P＜0.05). To sumup, the longer the sleep duration, the lower the degree of stress, and the quality of meals which can be saidto be a significant finding for high school students.
