Purpose. The purpose of this study was conducted to identify college students' sleep type and awareness of sleep. Methods. We researched 250 students in a college using the Korean Translation of Composite Scale(KtCS) and awareness of sleep questionnaire. Results. The sleeping hour of college students was 395.28 minute in average. The research showed that the biggest reason for the lack of sleep is using the computer, mobile and watching TV(22.6%), and most of them said that the lack of sleep is causing drowsiness during the daytime( 29.2%). For the questions asking when they feel drowsy during the daytime, most of them forcing themselves to stay awake(29.2%) and they caught up on sleep on the weekend(32.5%). Conclusions. Therefore college students to keep relevant sleep time and to know about the importance of the sleep.

Objectives : Some studies have reported that chronotypes, among several factors, could contribute to problematic drinking. However, there is little evidence confirming this relationship between chronotype and problematic drinking based on gender differences in mood disorder. This study is to investigate the difference of the relationship between chronotype and problematic drinking according to gender differences in mood disorder. Methods : Two hundred fifteen patients with mood disorder were recruited. Problematic drinking and chronotypes were assessed by the Alcohol Use Disorder Identification Test in Korea(AUDIT) and the Korean translation of composite scale of morningness(KtCS). We analyzed the correlation between KtCS and AUDIT using Pearson's correlation, and compared AUDIT scores according to chronotypes classified by KtCS between male and female patients using analysis of variance(ANOVA). Results : There was no significant difference in AUDIT scores between the male and female patients(t=0.91, p=0.183). In female patients, eveningness had significantly higher AUDIT scores than other chronotypes(F=0.199, p=0.033). Meanwhile, in male patients, there was no significant difference in AUDIT score among chronotypes(F=0.008, p=0.933). Conclusion : This study suggests that eveningness might be associated with problematic drinking in female patients who suffer from mood disorder. It also suggests that chronotherapeutical treatment might be able to help improve the course in female patients with mood disorder. In the future, a large-scale prospective study is needed to confirm these results.

목 적: 일 고등학교 학생들을 대상으로, 일주기 리듬을 아침-중간-저녁형으로 구분하여, 각 유형 간에 야간 수면 패턴의 차이를 살펴보고, 주간 졸림 및 피로 정도를 비교해 보았다. 방 법: 일 남자 고등학교 2학년 전체 학생 501명을 대상으로 자가설문조사를 하였다. 아침-저녁형 평가를 위한 한국어판 조합척도(Korean translation of composite scale : KtCS), 주중 기상 시 어려움(difficulty awakening), 주중 기상 시 졸린 정도(morning drowsiness), 주간 졸림 척도(Epworth sleepiness scale, ESS), 피로 정도 척도(Fatigue severity scale, FSS)를 이용하였다. 결 과: 저녁형(5시간 36분, SD=63.3분)이 중간형(6시간 11분, SD=61.8분, p<0.001)이나 아침형(6시간 23분, SD=61.8분, p=0.029)에 비해서 주중 평균 수면시간이 유의하게 짧았다. 저녁형은 주중에 매일 낮잠을 자는 비율(16.8%, p<0.001), 카페인 섭취 비율(58.8%, p<0.001), 코골이 비율(18.5%, p=0.037)이 유의하게 높았다. 저녁형은 주간 졸림 정도(8.7, SD=3.2, p<0.001)와 피로도(4.4, SD=1.2, p<0.001)에서 중간형이나 아침형보다 더 높은 점수를 보였다. 결 론: 저녁형 학생들은 주중에 수면패턴이 불규칙하고, 가장 심한 수면 부족을 겪고 있으며, 낮잠 빈도가 높았다. 저녁형은 주간 졸림 정도가 더 심하고, 심한 주관적인 피로감을 보고하였다. 수면 유형 평가 및 동반 수면 질환 여부 검사 등 학생들의 수면 양상에 대한 적절한 관심과 교육, 적극적인 개입이 필요할 것으로 생각된다.
