To investigate the relationship between insufficient sleep and poor attention in Korean adolescents, adjusting for potential confounding factors of depressed mood and habitual snoring.
School-based cross-sectional study.
Eight high schools in 3 cities in the Republic of Korea.
A sample of 2638 urban high school students (42.2% male and 57.8% female; mean [SD] age, 17.3 [0.6] years [age range, 14-19 years]) completed questionnaires and computerized attention tasks during the school term.
Weekend catch-up sleep.
Self-reported sleep schedules and habits, including sleep duration, bedtime, wake-up time, depressed mood, and habitual snoring. Also measured were numbers of omission and commission errors on computerized attention tasks.
The mean (SD) sleep duration on weekdays was 5 hours 42 minutes (1 hour 0 minutes) per day and on weekends was 8 hours 24 minutes (1 hour 36 minutes) per day. The mean (SD) weekend catch-up sleep was 2 hours 42 minutes (1 hour 42 minutes) per day. After adjusting for age, sex, depressed mood (Beck Depression Inventory score, ≥10), habitual snoring, and weekday sleep duration, increased weekend catch-up sleep was significantly associated with more omission and commission errors on sustained attention tasks (P < .001 and P = .03, respectively) and on divided attention tasks (P = .01 and P = .04, respectively).
Increased weekend catch-up sleep as an indicator of insufficient weekday sleep is associated with poor performance on objective attention tasks. Assessment of catch-up sleep and sleep duration may be useful for physicians to evaluate sleep insufficiency and its adverse effects on attention in adolescents.
在调整抑郁情绪和习惯性打鼾等潜在混杂因素的情况下，调查韩国青少年睡眠不足与注意力不集中之间的关系。
基于学校的横断面研究。
大韩民国3个城市的8所高中。
2638名城市高中生样本（男性占42.2%，女性占57.8%；平均[标准差]年龄为17.3[0.6]岁[年龄范围14 - 19岁]）在学期期间完成了问卷调查和计算机化注意力任务。
周末补觉。
自我报告的睡眠时间表和习惯，包括睡眠时间、就寝时间、起床时间、抑郁情绪和习惯性打鼾。还测量了计算机化注意力任务中的漏报和误报错误数量。
工作日的平均（标准差）睡眠时间为每天5小时42分钟（1小时0分钟），周末为每天8小时24分钟（1小时36分钟）。平均（标准差）周末补觉时间为每天2小时42分钟（1小时42分钟）。在调整年龄、性别、抑郁情绪（贝克抑郁量表评分≥10）、习惯性打鼾和工作日睡眠时间后，周末补觉时间增加与持续注意力任务（分别为P <.001和P =.03）和分散注意力任务（分别为P =.01和P =.04）中的更多漏报和误报错误显著相关。
作为工作日睡眠不足指标的周末补觉时间增加与客观注意力任务表现不佳有关。评估补觉和睡眠时间可能有助于医生评估青少年的睡眠不足及其对注意力的不良影响。
