Prevalence and associated factors of depression among tuberculosis patients in Eastern Ethiopia

Background: Depression among tuberculosis patients, especially in settings with low economic status is common. Screening for depression in all levels of health facilities can identify patients who need support and treatment for depression. Objective: The aim of this study was to assess the prevalence and associated factors of depression among tuberculosis patients in Eastern Ethiopia. Methods: An institutional based cross-sectional study was conducted among 403 tuberculosis patients attending in eleven tuberculosis treatment centers in eastern Ethiopia from February to July 2017. Depression was measured using the Patient Health Questionnaire. Data was collected consecutively until the required sample size was obtained. Tuberclusis patients who were under anti tuberculosis treatments for more than one month were included. Data were analyzed with Statistical Package for Social Sciences (SPSS) version 20. Bivariate and multivariate logistic regression models were applied to identify independent factors for dependent variable depression and P-values <0.05 considered statistically significant. Results: A total of 403 tuberculosis patients were included in the study. The prevalence of depression among tuberculosis patients was 51.9% (95%CI = 42.7, 62.2%) with 34.2% were mild cases. In our logistic regression analysis, odds of developing depression among tuberculosis patients with age less than 25 years were 0.5(50% protective effect) [AOR = 0.5, 95% CI 0.26-0.99] where as patients with a monthly income within the 25th percentile were four times higher odds to have depression [AOR = 3.98, 95% CI: 2.15-7.39]. Conclusion: The prevalence of depression was high in this study. Age, low monthly income, the category of patients as new tuberculosis treatment and the first 3 months of treatment was associated with depression among tuberculosis patients. Health facilities should integrating mental health services with tuberculosis clinics, especially assessing and treating TB patients for depression, is vital.
