Sleep quality in functional dyspepsia patients: A cross-sectional study from a tertiary care hospital in Karachi.

Objective: To determine sleep quality among functional dyspepsia (FD) patients presenting to gastroenterology out-patient clinic in a tertiary care hospital. Study Design: Cross-sectional study. Setting: Department of Gastroenterology, Liaquat National Hospital, Karachi, Pakistan. Period: March 2022 to December 2023. Methods: FD diagnosis was established in view of ROME-IV criteria. Sleep quality was evaluated using Pittsburgh Sleep Quality Index PSQI scoring tool. A global score of 5 or more indicates poor sleep quality. Binary logistic regression was applied and odds ratio with 95% confidence level were figured out to assess relationship of patients' profile with FD. Results: In a total of 240 patients, the mean age was 37.3±6.5 years. There were 122 (50.8%) male patients. The most common dyspeptic feature was postprandial fullness (60.4%) followed by early satiety epigastric pain (50%) and epigastric burning (39.6%). Mean PSQI score was 14.7±3.5. Frequency of poor sleep quality among FD patients was 79.2%. None of the parameter was significantly associated with sleep quality except urban residence (p=0.005). Conclusion: Very high burden of poor sleep quality was found among FD patients. While most dyspeptic symptoms did not show a significant association with sleep quality, urban residence emerged as a notable factor.
