Abstract

Background: Due to the irreversible nature of chronic obstructive pulmonary disease (COPD), the treatment aim
in patients with COPD is not to cure but to reduce the symptoms, increase lung function, and improve the quality
of life. It has been suggested that depression is a common emotional disturbance in patients with COPD who
are faced with a major physical impairment and embarrassing symptoms. This study evaluated the prevalence and
risk factors of depression in patients with chronic obstructive pulmonary disease.
Methods: A total of 59 patients with a registered diagnosis of chronic obstructive pulmonary disease were selected.
Depression was assessed using the Centers for Epidemiologic Studies Depression (CES-D) scale. The quality of
life was assessed using the Korean version of the St. George’s Respiratory Questionnaire.
Results: The prevalence of depression was 17.0%. In the correlation model, the interaction of the FEV1% over
predicted value and SGRQ score(symptom, activity, impact, overall score) was statistically significant. The interaction
of the FEV1% over predicted value and depression scale(CES-D) was also statistically significant. There was a positive
correlation between the SGRQ scores(symptom, activity, impact, overall score) and the depression scale.
Conclusion: The prevalence of depression in patients with chronic obstructive pulmonary disease is relatively high.
The pulmonary function and the living standards were found to be significant risk factors for depression.
