Objective To explore depression status in preoperative patients and its influence factors, and provide theoretical basis for psychological intervention. Methods A total of 734 preoperative patients were investigated by self-rating depression scale(SDS). Results Among the 734 patients, there were 558(76.02%) without depression,162(22.07%) of mild depression, 12(1.63%) of moderate depression, and 2(0.27%) of severe depression. The incidence of depression was 24.00%. Single factor analysis showed that gender, age, education level, career, income level,payment ways, smoking, and drug were correlated with depression among preoperative patients(P0.05). Logistic regression analysis showed that gender, age, income level and smoking were the influence factor of depression in preoperative patients. Conclusion The main influence factors of depression for preoperative patients are gender, age, income level and smoking, which should be paid attention to by medical staff and family in order to reduce the incidence of depression.
