Abstract

Objectives : The aim of this study was to compare psychosocial characteristics of the functional gastrointestinal disorders FGID group, non-FGID group, and control group and determine factors affecting the QOL of patients with FGID. Methods : 135 patients diagnosed with FGID were selected. 79 adults had no observable symptoms of FGID (control group) and 88 adults showed symptoms of FGID (non-FGID group). Demographic factors were investigated. The Korean-Beck Depression Inventory-II, Korean-Beck Anxiety Inventory, Korean-Childhood Trauma Questionnaire, Multidimensional Scale of Perceived Social Support, Connor-Davidson Resilience Scale, Patient Health Questionnaire-15 and WHO Quality of Life Assessment Instrument Brief Form were used to assess psychosocial factors. A one-way ANOVA was used to compare differences among groups. Pearson correlation test was performed to analyze the correlation of psychosocial factors and QOL of the FGID group. Further, a hierarchical regression analysis was conducted to determine factors affecting the QOL of the FGID group. Results : Between-group differences were not significant in demographic characteristics. Depression (F=48.75, p<0.001), anxiety (F=14.48, p<0.001), somatization (F=24.42, p<0.001) and childhood trauma (F=12.71, p<0.001) were significantly higher in FGID group than in other groups. Social support (F=39.95, p<0.001) and resilience (F=17.51, p<0.001) were significantly lower in FGID group than in other groups. Resilience (β=0.373, p<0.01) was the most important explanatory variable. The explained variance was 47.2%. Conclusions : Significantly more symptoms of depression, anxiety, childhood trauma, and somatization were observed for the FGID group. This group also had less social support, resilience, and quality of life than the non-FGID and control groups. The key factor for quality of life of the FGID group was resilience.

연구목적 본 연구에서는 FGID 환자군, FGID양성군 및 정상대조군에서 정신사회적 특성을 비교하고, 기능성위장질환 환자의 삶의 질에 영향을 주는 요인을 알아보고자 하였다. 방 법 원광대학교병원 소화기 내과 전문의에 의해 기능성위장질환으로 진단받은 환자135명을 FGID 환자군으로 선정하였다. 167명의 일 도 지역 공무원을 대상으로 로마 III 진단 기준에 따라 기능성위장증상을 보이지 않는 79명을 정상대조군, 기능성위장증상을 나타내는 88명은 FGID 양성군으로 선별하였다. 인구통계학적 요인을 조사하였으며 정신사회적 요인을 평가하기 위해 Korean version of the Beck Depression Inventory-II (K-BDI-II), Korean version of the Beck Anxiety Inventory (K-BAI), Korean version of Childhood Trauma Questionnaire (CTQ-K), Multi-dimensional Scale of Perceived Social Support (MSPSS), Korean Version of Connor-Davidson Resilience Scale (K-CD-RISC), Patient Health Questionnaire-15 (PHQ-15), World Health Organization Quality of Life Assessment Instrument Brief Form (WHOQOL-BREF)를 사용하였다. 일원배치 분산분석(one-way ANOVA)을 사용하여 집단들 간의 차이를 비교하고 FGID 환자군의 삶의 질과 정신사회적 요인들의 상관관계를 분석하기 위해 Pearson correlation test를 시행하였다. FGID 환자군의 삶의 질에 영향을 미치는 요인들을 알아보기 위해 위계적 회귀분석(Hierarchical regression analysis)을 시행하였다. 결 과 우울 증상(F=48.75, p<0.001), 불안(F=14.48, p<0.001), 아동기 트라우마(F=12.71, p<0.001) 및 신체화(F=24.42, p<0.001)에서 FGID 환자군이 다른 두 그룹에 비해 유의하게 점수가 높았다. 사회적지지(F=39.95, p<0.001)와 회복탄력성(F=17.51, p<0.001) 및 삶의 질(F=52.14, p<0.001)에서 FGID 환자군이 다른 두 그룹에 비해 유의하게 점수가 낮았다. Model 2에서는 Model 1에 심리적 변인들을 추가했으며 회복탄력성(β=0.373, p<0.01)이 가장 중요한 설명 변인이었다. 최종 회귀 모델의 설명 변량은 47.2%였다. 결 론 FGID 환자군은 FGID 양성군 및 정상대조군에 비해 우울 증상, 불안과 아동기 트라우마, 신체화가 유의하게 높았으며 사회적지지 및 회복탄력성, 삶의 질이 낮았다. FGID 환자군의 삶의 질에 주요한 요인은 회복탄력성이었다.
