Abstract:Objective To explore the possible risk factors for anxiety and depression in elderly patients with chronic obstructive pulmonary disease (COPD). Methods Totally 120 cases of COPD patients admitted to Wuhan Sixth Hospital from January 1, 2017 to January 1, 2018 were studied, and their sex, age, body mass index, educational background, course of illness and severity were collected, and the anxiety and depression score of the patients was evaluated by the anxiety and depression scale. According to the score, the subjects were divided into COPD combined with anxiety and depression (group A) and without anxiety and depression (group B). The observation indexes of the two groups were compared. Unconditional Logistic regression analysis was used to analyze the possible risk factors of COPD combined with anxiety and depression. Results Group A and group B were 57 cases and 63 cases respectively. The incidence of anxiety and depression was 47.5%. Compared with the group B, the scores of age, course of disease, body mass index, anxiety and depression scale were significantly higher in group A (P?0.05); there were significant differences in the level of education, severity, smoking and solitude (P?0.05); and there was no significant difference in sex ratio, source and independent income (P?>?0.05). The unconditional Logistic regression showed that the course of disease, body mass index and smoking were risk factors for COPD combined with anxiety and depression, which increased the risk of anxiety and depression of COPD patients to 1.434, 1.735 and 6.644 times respectively (P?0.05); high education and light illness as protective factors reduced the risk of COPD combined with anxiety and depression to 0.027 and 0.140 times respectively (both P?0.05). Conclusions The incidence of anxiety and depression in COPD patients; long course of disease, high body mass index and smoking are the risk factors, and high education and mild condition are protective factors.
