Possible depression in new tuberculosis patients in the Free State province, South Africa

Résumé fourni par la source

Background: Despite compelling evidence of comorbidity between tuberculosis (TB) and depression, little is known about the prevalence and determinants of depression among TB patients in the Free State province in South Africa. Objectives: This study assessed the prevalence and factors associated with possible depression among new drug susceptible TB patients attending primary health care facilities. Method: The study followed a cross-sectional design. Trained fieldworkers conducted face-to-face interviews with conveniently selected patients. Depression was assessed using the Patient Health Questionnaire-9. Data were subjected to descriptive and binomial logistic regression analyses. Results: Out of 208 patients, 46.2% screened positive for possible depression - 22.6%, 18.8%, and 4.8% presenting with mild, moderate, and severe symptoms, respectively. Possible depression odds were three times higher among females than males (adjusted odds ratio [AOR]: 3.0; 95% confidence interval [CI]: 1.25-7.32) and 2.7 times higher among extrapulmonary TB (EPTB) than pulmonary TB patients (95% CI: 1.03-7.21). Longer TB treatment duration was protective (AOR: 0.8; 95% CI: 0.70-0.95) against depression. Among human immunodeficiency virus-positive patients, those on antiretroviral therapy (ART) had 2.5 times higher odds of depression (95% CI: 1.13-5.46) than those who were not. Conclusion: The results highlight a significant burden of possible depression among new TB patients, particularly among females, EPTB patients, and ART recipients. Longer TB treatment duration may offer some protection against depression symptoms, suggesting a need for enhanced adherence support. Contribution: The results suggest that strengthening TB and mental health service integration is critical to improving treatment outcomes, overall well-being of TB patients, and the performance of the Free State TB programme.
