Abstract

Background/Aims: Several studies have demonstrated that sleep problems are associated with functional gastrointestinal disorders (FGIDs), such as irritable bowel syndrome (IBS), and functional dyspepsia etc, but the relationship between excessive daytime sleepiness (EDS) and FGIDs has not been systematically studied in general population. This study aimed to explore the relationship between EDS and specific types of FGIDs and the effect of the number of FGIDs on EDS.

Methods: A sample of 3600 individuals (aged 18-80 years) was selected from 5 regions in China using a randomized stratified multi-stage sampling method. EDS was measured by the Epworth Sleepiness Scale, while FGIDs and gastroesophageal reflux disease (GERD) were assessed by Rome II diagnostic criteria and Reflux Disease Questionnaire, respectively.

Results: The survey was completed by 2906 individuals (response rate: 80.72%), and 644 individuals (22.16%) had EDS. EDS was significantly associated with ulcer-like dyspepsia (OR, 2.50; 95% CI, 1.08-5.79), diarrhea-predominant IBS (OR, 2.00; 95% CI, 1.09-3.66), alternating IBS (OR, 2.32; 95% CI, 1.30-4.13), functional constipation (OR, 1.68; 95% CI, 1.20-2.35), and GERD (OR, 1.72; 95% CI, 1.08-2.72). Risk of EDS increased along with the increasing numbers of FGIDs: with 1 FGID (OR, 1.72; 95% CI, 1.37-2.15); with 2 FGIDs (OR, 2.43; 95% CI, 1.63-3.62); and with 3 or more FGIDs (OR, 3.26; 95% CI, 1.37-7.78).

Conclusions: FGIDs, such as ulcer-like dyspepsia, diarrhea-predominant IBS, alternating IBS, functional constipation, and GERD, were significantly associated with EDS. Those who suffered from more kinds of FGIDs were more susceptible to EDS.
