Abstract
Objectives: The purpose of this study was to assess the difference of subjective daytime sleepiness level between primary insomnia patients and healthy control subjects. We also investigated the relationship between subjective daytime sleepiness level and variables of nocturnal polysomnograghic sleep architecture of insomnia patients. Method: Total subjects were 87 patients with primary insomnia diagnosed with polysomnography and 88 normal controls. The daytime sleepiness level in each group was measured by Korean version of Epworth Sleepiness Scale (ESS). The correlations of ESS score and nocturnal polysomnographic variables were calculated in the patient group. Results: Patients with insomnia had the lower ESS scores than the control group. In patients group, the ESS score showed significant negative correlations with total sleep time, sleep efficiency%, and stage 2 sleep time%. The ESS score also showed significant positive correlations with number of awakenings, number of awakenings more than 2 minutes, and wake after sleep onset time. Conclusions: Insomnia patients showed lower level of subjective daytime sleepiness that may indicate their higher alertness comparing to control subjects. Daytime sleepiness of patients with insomnia was associated with polysomnographic variables including total sleep time, sleep efficiency%, stage 2 sleep time% and disrupted continuity of nocturnal sleep.
목 적:본 연구에서는 일차성 불면증으로 진단받은 환자들과 대조군 사이의 주간 졸림증 정도를 비교하고 불면증 환자에서의 주간 졸림증과 야간 수면다원검사에서 산출한 수면 변인 사이의 상관관계를 평가해 보고자 하였다. 방 법:서울대학교병원 수면 클리닉에서 일차성 불면증으로 진단받은 환자 87명과 88명의 대조군을 대상으로 하였다. 한국판 엡워스 졸림증 척도로 두 군의 주관적인 주간 졸림증을 평가하여 비교하였고 불면증 환자군에서 야간수면다원검사상의 수면변인과 엡워스 졸림증 척도 사이의 상관관계를 평가하였다. 결 과:불면증 환자군(남자 43명, 여자 44명; 평균연령
