목 적：폐쇄성무호흡증(Obstructive sleep apnea, OSA)과 단순코골이(simple snoring) 환자들의 성격적 특성에 대한연구가 부족한 실정으로, 본 연구에서는 아이젱크 성격검사(Eysenck Personality Questionnaire, EPQ)를 사용하여 OSA와 단순코골이 환자들의 성격적 특성과 차이를 연구하였다. 방 법：OSA나 단순코골이가 의심되는 237명의 피험자들이 연구에 포함되었다. 모든 피험자들은 EPQ 등의 설문검사를 받았고, 수면다원검사실에서 야간수면다원검사를 시행하였다. 무호흡저호흡지수(Apnea-Hypopnea Index, AHI)5 이상은 OSA, 5 미만은 단순코골이로 분류되었다. 결 과：OSA군은 단순코골이군에 비해 정신병적 경향성(Psychoticism)에서 유의하게 낮은 점수를 보였다(F=4.563,p=0.034). 기타 외향성-내향성(Extraversion, F=3.029, p=0.083), 허위성(Lie, F=0.398, p=0.529), 신경증적 경향성(Neuroticism,F=3.367, p=0.068)에서는 OSA군과 단순코골이 군간에 유의한 차이가 없었다. OSA군 내에서 시행한 상관분석결과 AHI가 높을수록 외향성(r=0.16, p=0.029)이 높았고, 허위성(r=-0.31, p＜0.001)이 낮았다. OSA군에서 EPQ의 네 가지 척도를 종속변인으로 설정한 다중회귀분석 결과, 허위성은 나이가 많고(B=0.14, p＜0.001), AHI가 낮을수록(B=-0.05,p＜0.001) 증가하였다. 정신병적 경향성은 피츠버그 수면질설문(Pittsburgh Sleep Quality Index, PSQI)이 높을수록(B=0.14, p＜0.001), 신경증적 경향성은 PSQI가 높고(B=0.34,p=0.001), 여성인 경우(B=3.15, p=0.003) 증가하였다. 외향성은 나이가 적고(B=-0.08, p=0.020), 체질량지수(body massindex)가 높을수록(B=0.26, p=0.023) 증가하였다. 결 론：본 연구 결과는 OSA 환자들이 단순코골이 환자들에 비해 유의하게 정신병적 경향성이 낮음을 보여주었다. OSA군 내에서는 AHI가 높을수록, 허위성이 낮고 외향성이높은 경향을 보였다.
Objective: Few studies have evaluated the personality characteristics of patients with obstructive sleep apnea (OSA) and simple snoring. We investigated the personality characteristics of OSA and simple snoring patients and compared differences in personality between the two groups using the Eysenck Personality Questionnaire (EPQ). Materials and Methods: Two hundred and thirty-seven patients who were suspected to have OSA or simple snoring participated in this study. A self-questionnaire which included the EPQ was administered to all participants. All subjects underwent polysomnography in a sleep laboratory and those with an apnea-hypopnea index (AHI) ≥5 were included in the OSA group, while those with an AHI ＜5 were included in the simple snoring group. Results: OSA patients had significantly lower scores for Psychoticism (F=4.563, p=0.034) than simple snorers. There were no significant differences in Extraversion (F=3.029, p=0.083), Lie (F=0.398, p=0.529), or Neuroticism (F=3.367, p=0.068) scores between the two groups. In the correlation analysis of the OSA group, AHI was positively correlated with Extraversion score (r= 0.16, p=0.029) and negatively correlated with Lie score (B=-0.31, p＜0.001). Using multiple stepwise linear regression analysis with the four EPQ parameter scores as dependent variables, Lie score was associated with older age (B=0.14, p＜0.001) and lower AHI (B=-0.05, p＜0.001), Psychoticism score was associated with higher Pittsburgh Sleep Quality Index (PSQI ; B=0.14, p＜0.001), Neuroticism score was associated with higher PSQI (B=0.34, p=0.001) and female sex (B=3.15, p=0.003), and Extraversion score was associated with younger age (B=-0.08, p=0.020) and higher body mass index (B=0.26, p=0.023). Conclusion: This study suggests that patients with OSA are significantly less prone to psychotic personality characteristics than those with simple snoring. Among OSA patients, higher AHI was correlated with low falsehood and high extraversion tendencies.
