Abstract
OBJECTIVE: The aim of this study was to investigate the predictor variables that could influence overlap syndrome in functional gastrointestinal disorders (FGID) among firefighters in Korea. METHODS: Data collected from 1217 firefighters in Korea were reviewed. FGID were diagnosed according to the Rome III diagnostic criteria. Psychological factors were measured by self-reported questionnaires. The scores for depression, anxiety, quality of life (QOL) and occupational job stress were analyzed. The correlation between psychological factors and QOL was analyzed and a stepwise multiple regression analysis was performed. RESULTS: FGID were observed in 461 (37.9%) participants. In those with FGID, functional heartburn (FH) was most common (32.2%), followed by functional dyspepsia (12.2%). Patients with overlap syndrome had the highest depression, anxiety and occupational stress score than those having non-overlap syndrome and healthy controls, respectively (depression: F = 142.29, η(2) = 0.190; anxiety: F = 88.33, η(2) = 0.127; occupational stress: F = 43.68, η(2) = 0.067; all P < 0.001). Healthy controls had the highest QOL score (F = 73.39, P < 0.001, η(2) = 0.108). Pychological factors were significantly correlated with QOL in the overlap syndrome of FGID. After the stepwise selection, the final model explained 45.6% of predictable variance and contained four significant variables: depression, self-esteem, occupational stress and anxiety. CONCLUSIONS: Psychological factors are associated with the overlap syndrome of FGID. Acknowledging this common comorbidity may facilitate the recognition and treatment of patients with FGID.
