Background: This study investigated the relationship between sleep duration and school performance in Korean adolescents. Methods: In 2012, 63,688 adolescents participated in the 8th Korea Youth Risk Behavior Web-Based Survey (KYRBWS-VIII) project. The relationship between sleep duration and school performance was evaluated by multivariate logistic regression analysis after adjustment for covariate variables, including body mass index, age, parental education, economic status, mental stress, smoking, alcohol consumption, breakfast patterns, and three measures of physical activity. Results: For boys, but not girls, 5–6 hours of sleep/night was related to average or better academic performance (OR: 1.094, 95% CI [1.011–1.182], p = 0.025) compared to ≤ 4 hours/night. For both boys and girls nine or more hours/night was negatively related to academic performance (boys: 0.657, [0.554–0.779; p < 0.001]; girls: ≥ 9 hours/night, 0.664 [0.572–0.771], p < 0.001) compared to ≤ 4 hours/night. Conclusion: Whilst it may appear that five to six hours of sleep is necessary to maintain average or better than average school performance for boys while nine or more hours is detrimental to school performance for both groups, this study was limited by the following factors: data was collected only for weekdays and it is unknown how, or whether, this group caught up on the accumulated sleep debt over weekends. Furthermore, the majority of data collected was based on subjective responses and measures rather than objectively measured variables. Other sleep variables, such as quality of sleep and sleepiness, were not investigated and should be investigated for a further understanding of these results. | ||
