Investigation of Sleep Quality and its influencing factors in Iranian Patients with Esophageal and Gastric Cancer

Abstract Sleep quality is one of the noteworthy clinical constructs, which affect physical and mental health. The main approach of this study was to investigate sleep quality and its influencing factors among patients suffering from esophageal and gastric cancer. Pittsburg Sleep Quality Index (PSQI) was completed by 312 cancer patients aged from 18 to 93. Univariate and multivariable logistic regression was applied. The Results demonstrated that about 66% of cancer patients had poor sleep quality regardless of their cancer type and stage. Furthermore, Wealth Index (WI), chronic diseases, and marital status seemed to influence cancer patients' sleep quality. In conclusion, it may seem that paying more attention to these influencing factors will improve the sleep quality of cancer patients.
