Excessive daytime sleepiness in childhood might be abnormal phenomenon and often related to the sleep disorders or insufficient sleep duration. The most common cause of excessive daytime sleepiness would be insufficient sleep. However, narcolepsy, idiopathic hypersomnia, circadian rhythm sleep disorders, medication, medical illness and other sleep disorders that could cause insomnia and poor quality of sleep also result in excessive daytime sleepiness. The misdiagnosed and untreated excessive daytime sleepiness in childhood can lead to serious developmental and educational problem.

Objective : The aim of this study was to investigate the relationship among daytime sleepiness, depressive symptoms, anxiety symptoms, and stress response of students in a university Methods : A total of 557 students were recruited in this study. The participants filled out stress response inventory, Epworth sleepiness scale, overall anxiety severity and impairment scale, and quality of life scale. Results : Excessive daytime sleepiness group showed higher scores in all factors in stress response inventory, overall anxiety severity and impairment scale, and quality of life scale. Sleepiness might be correlated with somatization and depression and anger in Stress response inventory. Conclusion : Excessive daytime sleepiness group exhibited poor quality of life scale. Screening about overall quality of sleep, such as mood and anxiety should be considered for students in a university.

수면의학에서 사용되는 여러 설문지 검사중 과도한 주간졸음과 일주기리듬의 평가를 위한 것들을 소개하고 그 장단점과 특성을 검토하였다. 임상수면의학, 산업의학, 혹은 역학조사에서 이러한 지필척도의 활용이 요구되고 있으나 아직 객관적 타당성이 충분히 검토되지 못했으므로 추후연구가 요구된다. 타당성을 제고할 임상, 혹은 교대근무상황에서의 연구가 더욱 확장되어야 할 것이다.

Sleep-related breathing disorders, especially sleep apnea syndrome are complicated by neuropsychiatric dysfunction such as excessive daytime sleepiness, cognitive dysfunction, and depression. As the determinants of daytime sleepiness, sleep fragmentation is more influential than nocturnal hypoxia. Daytime sleepiness can be improved by continuous positive airway pressure (CPAP) or surgery in up to 95% of the treated subjects. Both sleepiness and nocturnal hypoxia would cause cognitive dysfunction. While impairments in attention and verbal memory are more related with sleepiness and prominent in mild to moderate sleep apnea syndrome (SAS), impairments in general intellectual function and executive function are more related with nocturnal hypoxia and prominent in severe SAS. Several cognitive deficits related with nocturnal hypoxia may be irreversible despite CPAP or surgical treatments. So, early detection and early appropriate treatment of SAS would prevent sleepiness and cognitive deterioration.

목 적：수면 결핍과 과도한 주간졸림증은 교통사고와 산업재해, 생산성 저하, 학습장애, 대인관계 문제 등의 심각한 결과를 초래할 수 있다. 이러한 부정적인 영향에도 불구하고, 수면 부족과 주간졸림증에 관한 역학 연구는 거의 없는 실정이다. 본 연구에서는 얼마나 많은 사람들이 수면 결핍을 경험하고 있는지, 주말에 얼마나 많은 회복 수면이 일어나는지, 그리고 회복 수면량과 주간졸림증 간의 관련성에 대해 알아보고자 하였다. 방 법：164명(남 65명, 여 99명)의 지원자가 광고를 통해 모집되었으며, 이들은 서울에 거주하는 20세 이상의 직장인 및 대학생으로, 평균 연령은 남자 $33.4{\pm}11.64$세, 여자 $31.9{\pm}9.68$세이었다. 본 연구의 배제 대상은 60세 이상, 불면증이나 주간졸림증을 유발할 수 있는 의학적, 신경학적, 정신과적 장애와 수면장애가 있는 사람, 수면 스케줄이 불규칙한 사람, 최근 해외여행을 다녀온 사람, 출퇴근을 하지 않거나 교대근무자이었다. 연구 참여자들은 2주일간 매일 아침 수면일지를 작성하였고, 둘째 주 마지막 날 정오 무렵에 Epworth Sleepiness Scale(ESS)를 작성하였다. 모든 분석은 SPSS/PC+를 사용하였으며 t 검증, 카이제곱 검증, 또는 변량분석을 시행하였다. 결 과：본 연구의 결과는 참여자들이 평일에는 6시50분, 토요일에는 7시9분, 그리고 휴일을 포함한 일요일에는 8시 12분에 잠에서 깨었으며, 일요일에는 평일이나 토요일에 비해 더 빈번하게, 그리고 더 오랫동안 낮잠을 잔다는 사실을 보여주었다. 평일에는 야간 수면시간이 평균적으로 6시간 30분인데 비해, 주말에는 약 1시간이나 더 늦잠을 자는 경향이 있었다. 평일에 8시간 이상 수면을 취하는 사람은 연구대상의 9.1%에 불과하였고, 약 67%는 7시간보다 적게 잠을 잤으며, 49.4%는 일요일에 1시간 이상의 회복 수면을 보고하였다. 일요일에 회복수면이 2시간 이상인 사람들은 30분 이하인 사람들보다 유의하게 더 많은 주간졸림증을 호소하였다. 결 론：이러한 결과는 수면 결핍과 과도한 주간졸림이 한국 도시 성인에서 비교적 흔하며 평일에 수면이 불충분한 사람들은 일요일에 늦잠이나 낮잠을 잠으로써 수면 부족을 보충하려고 시도한다는 사실을 보여준다. 회복 수면량은 주간졸림증과 관련이 있으며, 수면 결핍은 축적된 효과를 가지고 낮시간의 졸리움을 증가시키는 것처럼 보인다.

We report a case of narcolepsy. A 25-year-old man has had excessive daytime sleepiness of about 10 years durations. He awakens daily feeling exhausted and continually falls asleep during the day while engaged in such situation like reading and watching television. He has exhibited cataplexy, a sudden loss of muscular tone, brought on by emotion, usually laughter. Polysomnogram revealed increased sleep stage 1, 2 and decreased deep sleep. Multiple sleep latency test (MSLT) showed that sleep latency was 1.33 minutes and there were 3 noted sleep onset rapid eye movement (SOREM) on 5 trials. The epworth sleepiness scale (ESS) was 17/24. Typing of HLA haplotype that was positive for the $DQB1^{\ast}0602$ allele, and hypocretin-1 (orexin A) could not be detected in cerebrospinal fluid (CSF). Brain MRI showed normal image. We diagnosed his case as narcolepsy based on history of cataplexy, and three occurances of SOREM, and positive of HLA haplotype.

Purpose: The purpose of this study was to investigate sleep patterns and predictors of excessive daytime sleepiness (EDS) in university students. Methods: Participants were 120 university students who were attending two universities in S-city and C-city. Data were collected from May 20 to June 15, 2012 using self-report questionnaires which included Johns' Epworth Sleepiness Scale, Yi's Sleep Quality Scale, and Beck Depression Inventory. Data were digitalized and analyzed using frequency, percentages, means and standard deviations, Wilcoxon rank sum test, Chi-square test, Fisher's exact test, and multiple logistic regression with SAS 9.0. Results: Mean total sleep time was 6.6 hours on weekdays, 8.1 hours on weekends. Mean sleep latency was 19.1 minutes and the score for mean sleep quality was 22.6. Prevalence of EDS was 12.5%. Depression was significantly different between EDS and Non-EDS students (t=2.17, p=.030). Multiple logistic regression showed that the only factor associated with EDS was depression (adjusted odds ratio of depression=5.33, 95% Confidence Interval=1.49-19.04). Conclusion: Results of this study indicate that university students experience short sleep time, low sleep quality, and common EDS with depression, suggesting that students with complaints of EDS should be completely assessed for depression as well as sleep problems.

Purpose: The purpose of the present study was to identify prevalence of excessive daytime sleepiness(EDS) and its associations with sleep habits, sleep problems, depression, subjective health status and obesity in community dwelling adults. Method: Data was collected from adults aged 20-59 years by random sampling. Subjects completed a questionnaire which was composed of the Epworth Sleepiness Scale, Center for Epidemiologic Studies Depression Scale, and questions that included items about sleep habits, sleep problems, subjective health status and sociodemographic characteristics. Height and weight were measured for calculation of body mass index. The statistical analyses was based on 3,302 adults (51.5% males and 48.5% females). Descriptive statistics, univariate logistic regression and multiple logistic regression were used. Result: The prevalence of EDS was 17.1% Multiple logistic regression showed that the associated factors of EDS were depression, obesity, dissatisfaction with sleep time, irregular sleep, and habitual snoring. Depression was the most significant associated factor(adjusted odds ratio for severe depression=2.27, 95% Confidence Interval=1.73-2.96). Conclusion: EDS is a common symptom in adults. Our finding suggested that persons with a complaint of EDS should be completely assessed for depression and obesity as well as sleep problems.

Sleep apnea syndrome is a common clinical disorder characterized by intermittent cessation of airflow at nose and mouth during sleep. The clinical significance of this syndrome is that it is one of the most common causes of excessive daytime sleepiness. It can also cause neuropsychiatric, cardiovascular, and cerebrovascular complications. The standard for diagnosis of sleep apnea syndrome is nocturnal polysomnography. Because polysomnography is a time-consuming and expensive test, many efforts have been made to replace polysomnography with a simpler system of monitoring, but no method has yet been approved as a definitive investigation method. The goals of treatment for this syndrome are to eliminate excessive daytime sleepiness and to reduce the risk of possible cardiovascular complications. Continuous positive airway pressure is the most definite and widely accepted treatment for achieving these goals. Other treatments such as surgical treatment, oral appliances, and behavioral therapy may be useful for selected patients who are mildly affected.
