Analysis of Depression and Anxiety in Patients with Chronic Obstructive Pulmonary Disease

Objective: To estimate the prevalence of depression and anxiety in patients with Chronic Obstructive Pulmonary Disease(COPD) and to analyze the possible impact factors.Methods: Sixty-two patients with COPD were measured with Hospital Anxiety and Depression Scale(HAD).Results: Fourty-two(67.7%) patients had depressive symptom,and 43 cases(69.3%) had anxiety symptom.There were 13 patients who had significant depression and anxiety symptoms from 14 patients with III-level-COPD.From logistic-regression analysis model,we found that males had more risk of depression/anxiety symptoms than females(OR 1.05,95%CI1.01~2.11,1.12,95%CI 1.03~2.23,respectively) and the risk of depression/anxiety symptoms was 2.34/2.53 times greater for patients with severe COPD than those for mild(OR 2.34,95%CI 1.98~3.21,2.53,95%CI 2.11~4.01,respectively).Meanwhile,the patients who knew more about their disease had more risk of depression/anxiety symptom than those who knew less(OR 1.22,95%CI 0.98~1.54,1.25,95%CI 1.01~2.31,respectively).Conclusion: There is a high prevalence rate of depression/anxiety symptom in patients with COPD and the degree of lung function impairment is the important impact factor.
