The quality of sleep is a significant factor in overall well-being and can potentially play a role in the development and progression of chronic diseases and cancers. In the current study, our aim was to investigate sleep quality and its associated factors among patients diagnosed with esophageal and gastric cancer.

We conducted a prospective study in which we administered the Pittsburgh Sleep Quality Index (PSQI) to 312 adult patients who had recently been diagnosed with esophageal and gastric cancers at a referral hospital. These patients were treatment-naïve at the time of the study. We utilized both univariate and multivariable logistic regression analyses to examine the data.

Among the participants, 203 (65.06%) were male, and the average age was 63.13±12.10 years. The results revealed that approximately 66% of the patients experienced poor sleep quality, regardless of their specific cancer type or stage. Notably, among those with poor sleep quality, 76.29% had esophageal cancer, while 23.71% had gastric cancer. Additionally, poor sleep quality was more prevalent among females, older individuals, and those with pre-existing chronic diseases. Living alone was also associated with a decrease in sleep quality. Furthermore, a significant proportion of individuals with good sleep quality had a favorable Wealth Index.

In conclusion, it appears that by paying closer attention to these influencing factors, we may be able to enhance sleep quality and, consequently, improve overall quality of life for patients dealing with esophageal and gastric cancer.
