Abstract
ABSTRACT Aim: To study psychiatric co-morbidities, anxiety, depression, and quality of life in patients of chronic obstructive pulmonary disease (COPD). Materials and Methods: A cross-sectional, case-control study was conducted on 122 cases of COPD and equal number of age- and sex-matched controls in a tertiary care hospital. They were assessed with the Mini-International Neuropsychiatric Interview (MINI), depression, anxiety stress scale-42 (DASS-42), St. George Respiratory Questionnaire (SGRQ), and COPD Assessment Test (CAT). Results: COPD patients and control subjects were matched with respect to age, sex, education, employment, domicile, and socioeconomic status. Psychiatric disorders were diagnosed in 56% of cases and 14% of controls. Major depressive disorder, alcohol dependence, and anxiety disorders were the most common psychiatric diagnoses. There was significantly higher prevalence of smoking in cases with COPD compared to control subjects suicidality was present in two patients. The mean scores on depression, anxiety, and stress on DASS-42 of COPD patients were significantly higher than normal controls. On the CAT majority of the COPD patients belonged to the high-impact group followed by the very high-impact group. Mean scores on the SGRQ were in the range expected in COPD patients. A multiple regression analysis revealed that significant predictors of SGRQ scores were age, gender, economic status, domicile, alcohol habits, depression, anxiety, and stress. Conclusion: COPD patients have a significantly higher prevalence of psychiatric co-morbidities compared to healthy controls. Common psychiatric disorders were major depression, alcohol dependence, and anxiety disorders along with smoking.
