Abstract

Abstract: Background and aim: Gastroesophageal reflux disease (GERD) and psychological stress are associated with sleep disturbances. The aim of the present study was to examine the prevalence of sleep disturbances, anxiety, and depression by GERD subtypes and to identify factors associated with sleep disturbances in general population. Methods: A total of 2002 Japanese subjects, who underwent annual health checkups, were enrolled and asked to fill out a questionnaire, including the frequency scale for the symptoms of GERD (FSSG), Athens Insomnia Scale (AIS), Rome III questionnaire, and Hospital Anxiety and Depression Scale (HADS). GERD was divided into asymptomatic erosive reflux disease (a-ERD), symptomatic ERD (s-ERD), and non-erosive reflux disease (NERD), according to the presence or absence of esophageal mucosal injury on endoscopy, and the FSSG scores. Sleep disturbances were diagnosed in subjects with AIS score ≥6. Results: Prevalence of sleep disturbances was significantly higher in GERD subjects than in controls (35.9 and 14.7%, respectively), especially, in the NERD group (45.1%). Sleep duration was significantly shorter in the s-ERD group compared with other groups. Subjects in the NERD and s-ERD groups showed higher HADS scores, resulting in higher incidences of anxiety and depression than those in the control and a-ERD groups. Reflux symptoms, anxiety, depression, and coexisting functional dyspepsia, but not the presence of esophageal mucosal injury, were associated with an increased odds ratio for sleep disturbances. Conclusion: There were significant positive associations among reflux symptoms, psychological stress, and sleep disturbance in Japanese adults. Further studies investigating the efficacy of therapy are needed.
