The characteristics and related factors of insomnia among postoperative patients with gastric cancer: a cross-sectional survey.

This study aims to explore the characteristics and related factors of insomnia of patients after operation for gastric cancer. A cross-sectional survey was carried out and finally 115 patients with insomnia after operation for gastric cancer were included. The general information, gastric cancer-related information, sleep quality, and other symptoms were investigated. ① The Pittsburgh sleep quality index score of most insomnia patients after gastric cancer surgery was 11-15 points, and the sleep quality rating was “poor”. ② The sleep quality of patients with insomnia after surgery for gastric cancer is related to the number of chemotherapy cycles, fatigue, and depression. ③ The probability of reduced sleep quality with the number of chemotherapy cycles >6 is 3.640 times that of ≤6. The probability of reduced sleep quality during moderate to severe fatigue was 4.390 times that of patients with no or mild fatigue. Attention to related factors may be associated with improvement of sleep quality in patients with gastric cancer after surgery.
