Abstract

This study aims to identify the prevalence of sleep related disease in those who experienced car accidents caused by drowsy driving. To this end, a survey of usual sleep habits, polysomnography, and multiple sleep latency tests were conducted in 34 persons who experienced an accident after normal sleep (Group 1), 22 persons who experienced an accident after abnormal sleep (Group 2), and 17 persons who was proven to be normal as a result of polysomnography and had no accident (Group 3). In all, 192 persons responded to the preliminary survey and the results were compared and analyzed. Crossover analysis was conducted to test the homogeneity of statistical characteristics, and the physical characteristics by age were analyzed. In the survey of sleeping habits, there was a significance between groups in how often they woke up while asleep (p<0.01), how difficult it was to go back to sleep again after waking up from sleep (p<0.05), how early they woke up in the morning (p<0.05), how difficult it was to get up in the morning (p<0.05), how sleepy they felt in the daytime (p<0.01), and how tired they felt in the daytime (p<0.01). Furthermore, among 56 subjects who had an accident during drowsy driving, 94.6% (53 persons) were found to have sleep related diseases. This suggests that car accidents during drowsy driving is not simply caused by temporary lack of sleep but by sleep related diseases even when sleep is adequate, leading to car accidents. Therefore, this study is significant identifying the association between car accidents during drowsy driving and sleep related disorders. Furthermore, the data would be considered basic to prepare social measures against drowsy driving related to such sleep related disorders.

본 연구는 졸음운전 사고 경험자들의 수면관련 질환에 관한 유병율을 조사하기 위하여 설문에 응답한 192명 중에서 정상수면 후 사고 경험자 34명(그룹 1), 비 정상수면 후 사고 경험자 22명(그룹 2), 수면다원검사 결과가 정상이면서 사고 경험이 없는 17명(그룹 3)을 대상으로 평상 시 수면습관에 대한 설문 결과와 수면다원검사, 다중수면잠복기검사 결과를 비교 분석하였다. 수면습관에 대한 설문에서 잠자는 동안 얼마나 자주 깨는지(p<0.01), 한번 잠에서 깬 후 다시 잠들기 얼마나 어려운지(p<0.05), 아침에 얼마나 빨리 깨는지(p<0.05), 아침에 일어나기 어려운 정도(p<0.05), 낮에 졸리운 정도(p<0.01), 낮에 피곤한 정도(p<0.01)에서 그룹 간 유의성이 확인되었다. 또한, 졸음운전 교통사고 경험이 있는 연구대상자 56명 중, 94.6% (53명)에서 수면 관련 질환이 확인 되었다. 따라서 졸음운전 교통사고가 단순하게 일시적 수면부족만이 원인이 아니라 수면시간이 충분해도 수면관련 질환의 영향으로 주간졸음증이 발생하고, 그로 인해 교통사고 등이 발생한다는 것을 확인하였다. 따라서 본 연구는 졸음운전 교통사고와 수면 관련 질환 사이의 연관성에 대해 확인해 보는 것에 의의가 있었다. 또한 이 데이터들은 수면질환과 관련된 졸음운전에 대하여 사회적 대책 마련을 강구하는데 필요한 기초 자료가 되리라고 사료된다.
