ABSTRACT
PURPOSE:
Korean adolescents have severe nighttime sleep deprivation and daytime sleepiness because of their competitive educational environment. However, daytime sleep patterns and sleepiness have never been studied using age-specific methods, such as the pediatric daytime sleepiness scale (PDSS). We surveyed the daytime sleepiness of Korean adolescents using a Korean translation of the PDSS.METHODS:
We distributed the 27-item questionnaire, including the PDSS and questions related to sleep pattern, sleep satisfaction, and emotional state, to 3,370 students in grades 5-12.RESULTS:
The amount of nighttime sleep decreased significantly with increasing age. During weekday nights, 5-6th graders slept for 7.95+/-1.05 h, 7-9th graders for 7.57+/-1.05 h, and 10-12th graders for 5.78+/-1.13 h. However, the total amounts of combined daytime and nighttime sleep during weekdays were somewhat greater, 8.15+/-1.12 h for 5-6th graders, 8.17+/-1.20 h for 7-9th graders, and 6.87+/-1.40 h for 10-12th graders. PDSS scores increased with age, 11.89+/-5.56 for 5-6th graders, 16.57+/-5.57 for 7-9th graders, and 17.71+/-5.24 for 10-12th graders. Higher PDSS scores were positively correlated with poor school performance and emotional instability.CONCLUSION:
Korean teenagers sleep to an unusual extent during the day because of nighttime sleep deprivation. This negatively affects school performance and emotional stability. A Korean translation of the PDSS was effective in evaluating the severity of daytime sleepiness and assessing the emotional state and school performance of Korean teenagers.
