Correlation between sleep impairment and functional dyspepsia.

Area of Science:

• Gastroenterology
• Sleep Medicine
• Psychosomatic Medicine

Background:

• Sleep habits significantly influence the occurrence of functional dyspepsia (FD).
• Understanding the link between sleep disturbances and FD is crucial for patient management.

Purpose of the Study:

• To investigate the association between various aspects of sleep impairment and the prevalence of FD.
• To identify specific sleep quality components that may serve as risk factors for FD.

Main Methods:

• A prospective study involving 418 university student volunteers.
• FD diagnosis utilized Rome IV criteria, categorizing participants into FD and control groups.
• Sleep quality assessed using the Pittsburgh Sleep Quality Index (PSQI), alongside Rome IV questionnaires and visual analogue scales (VAS).

Main Results:

• Participants with FD exhibited poorer sleep quality, longer sleep latency, shorter sleep duration, reduced sleep efficiency, and increased daytime dysfunction compared to controls.
• Specific components of the PSQI were identified as risk factors for FD and were more pronounced in the long-term FD group.
• PSQI components correlated positively with the frequency and severity of postprandial distress syndrome and early satiety, and total PSQI scores correlated with VAS scores.

Conclusions:

• Certain components of sleep quality, as measured by the PSQI, are significantly associated with the occurrence of FD.
• These sleep quality factors also correlate with increased symptom frequency and severity in individuals with FD.
