초록

목 적: 의과대학생들은 많은 스트레스를 받으며 점점 불 안감이 높아지고 수면시간의 부족과 함께 수면양상도 불규칙 해진다. 따라서 의과대학생들의 일주기 유형, 수면의 질, 회복탄력성 그리고 불안이 어떠한 연관이 있는지 알아보고자 하였다. 방 법: 경상국립대학교 의과대학생 본과 1학년 52명과 2년 후, 44명의 본과3학년 학생들을 대상으로 했다. 벡 우울 척도, 벡 불안 척도, 불면증 심각성 척도, 아침활동형 척도 그리고 코너-데이비드슨 탄력성 척도를 자기 설문지로 사 용하였다. 각각의 상호 연관성을 알아보기 위하여 다중회귀 분석을 시행하였다. 결 과: 본과 1학년 때의 불안이 높은 것은 2년 뒤인 3학년때 저녁형을 예측했고 본과 1학년때의 불안이 낮을수록 본과 3학년의 수면의 질이 좋았다. 본과 3학년의 수면의 질 이 낮은 것은 저녁형 그리고 낮은 회복탄력성과 연관이 있었다. 또한, 본과 3학년의 우울감이 적은 것은 높은 회복탄력성과 유의한 연관성을 보였다. 결 론: 본 연구에서 의과대학생 본과 1학년 때의 불안의 정도가 2년 후 3학년 때의 수면의 질과 저녁형을 예측했다. 앞으로 1학년 학생들의 불안을 낮출 수 있는 방안을 고안하여 학 생들의 수면의 질을 높이고 삶의 질을 향상시킬 필요가 있다.

Abstract

Objectives: Our study aimed to investigate the relationship between the anxiety at first year and chronotype and sleep quality at third year in medical students. We also investigated the association between sleep quality, chronotype, depression and resil¬ience at third year. Methods: Fifty two medical students (36 males, 69%, aged 21 ± 0.93) in first year, and forty four medical students (31 males, 70.5%, aged 23.05 ± 0.99) at third year answered Beck Depression Inventory 2, Beck anxiety inventory, Insomnia severity in¬dex-K, Composite scale of morningness and Conner-Davidson Resilience scale-10. Multiple linear regression analysises were performed to identify predictors of chronotype, sleep quality and resilience. Results: Higher anxiety (β = -0.434, p = 0.006) at first year was significant predictor of eveningness at third year, while lower anxiety score (β = 0.606, p < 0.001) at first year was significant predictor of sleep quality at third year. Lower sleep quality (β = -0.314, p = 0.042) and eveningness (β = 0.315, p = 0.041) were associated with low resilience at third year. Also, Lesser de¬pression (β = -0.717, p < 0.001) was associated with higher resilience at third year. Conclusion: Our study showed that higher anxiety in first year had significantly related with eveningness and poor sleep quality at third year. In addition, higher sleep quality, morningness and less depression had significantly associated with better resilience at third year.
