Association between digestive symptoms and sleep disturbance: a cross-sectional community-based study

BackgroundThis study was conducted to analyze the association between digestive symptoms and sleep disturbance, and to determine if any digestive symptoms are related to sleep disturbance.MethodsThis was a cross-sectional study of 5792 subjects surveyed in a community-based cohort. Subjects provided information regarding the quality of sleep as assessed by the Pittsburgh Sleep Quality Index (PSQI), as well as digestive symptoms as assessed by the Gastrointestinal Symptom Rating Scale (GSRS). Logistic regressions were used to examine factors associated with sleep quality.ResultsThe mean PSQI global score of the no sleep disturbances group (n=4948) was 3.92 (SD=2.14), while that of the sleep disturbance group (n=844) was 11.18 (SD=2.17). The association between digestive symptoms and sleep disturbance was evaluated by logistic regression after adjusting for cofounding factors. The results revealed that sleep disturbances were associated with digestive symptoms (aOR=1.29, 95% CI=1.22-1.36), especially abdominal pains (aOR=1.63, 95% CI=1.19-2.25), acid regurgitation (aOR=1.48, 95% CI=1.17-1.86), abdominal distension (aOR=1.80, 95% CI=1.42-2.28), and eructation (aOR=1.59, 95% CI=1.24-2.03).ConclusionsDigestive symptoms and sleep disturbances seem to be associated. These results will help medical professionals to effectively diagnose and manage patients with sleep disturbance. Furthermore, subsequent studies using comprehensive longitudinal data should be conducted to confirm the results of the present study.
