Common mental disorder among patients with chronic respiratory disease

Abstract

Introduction Mental disorders are common among patients with chronic respiratory disease, such as depression and anxiety. The objective of this study was to determine the prevalence of a common mental disorder, among patients with chronic respiratory disease (COPD). Patients and methods This is a cross-sectional study that was conducted in a public sector hospital. A total of 255 patients were selected through simple random sampling to be included. A structured and validated Patient Health questionnaire 9 was used to determine the presence of common mental disorder among patients. Logistic regression analysis was done to determine the association between mental disorder and respiratory disease, with adjustment of duration of disease, sex, and age. Results The prevalence of mental disorder among patients with COPD was rated as moderate, moderately severe, and severe in 33.5, 23.3, 32%, and 37%, respectively. After adjustment of covariates, females [odds ratio (OR) 1.90; confidence interval (CI) 2.32–4.25], smoker [OR 1.08 (CI 1.65–2.57)], and more than 10-year of duration of respiratory illness [OR 2.25 (1.98–3.21)] were statistically significant predictors of mental disorder in patients with chronic respiratory disease (COPD). Conclusion Patients with chronic respiratory diseases had a high prevalence of mental disorder, and common factors such as female sex, smoking, and duration of disease associated with depression. There is a need for developing health promotion programs including counseling of patients with a psychiatrist to reduce the burden of mental disorder among such patients.
