Mental Health Impacts of Multidrug-Resistant Tuberculosis in Patients and Household Contacts: A Mixed Methods Study

Multidrug-resistant tuberculosis (MDR-TB) patients experience disproportionately worse mental health, with implications for adherence, outcomes, and families. Comprehensive assessments of comorbid depression/anxiety and related factors remain limited.

This study aimed to assess the prevalence, predictors, and qualitative experiences of depression and anxiety in MDR-TB patients and household contacts.

A sequential explanatory mixed methods study was conducted in Gujarat, India, with 403 smear-positive MDR-TB patients and 403 contacts. The quantitative phase administered structured questionnaires on sociodemographic factors, clinical history, depression/anxiety symptoms, and psychosocial stressors (like stigma and social support). Logistic regression models were used. The qualitative phase included in-depth interviews with 30 purposively sampled patients for thematic content analysis. Results were integrated to contextualize quantitative findings.

High rates of depression (37.5%, n = 151) and anxiety (45.2%, n = 182) were documented among the MDR-TB patients, significantly greater than household contacts (20.1%, n = 81 and 25.1%, n = 101, respectively). For depression, older age (adjusted odds ratio (AOR) 2.03, 95% CI 1.01-4.05), female gender (AOR 2.5, 95% CI 1.1-6.0), divorced/widowed status (AOR 3.8, 95% CI 1.1-8.0), financial constraints, substance abuse (AOR 1.7, 95% CI 1.1-2.7), greater disease severity (AOR 1.8, 95% CI 1.5-2.2), medication side effects (AOR 2.4, 95% CI 1.2-4.6), and perceived stigma (AOR 3.2, 95% CI 1.1-5.3) emerged as significant risk factors. For anxiety, significant predictors were less social support (AOR 0.81, 95% CI 0.71-0.86), higher perceived stigma (AOR 2.2, 95% CI 1.1-6.3), greater disease severity (AOR 2.6, 95% CI 1.3-4.0), and more medication side effects (AOR 3.3, 95% CI 1.1-5.5). Prominent themes included psychological impacts like depression and anxiety, experiences of stigma and caretaking challenges, and recommendations for comprehensive patient support services.

MDR-TB patients experience a substantially higher dual disease burden of depression and anxiety, elevating the risk for adverse outcomes and transmission. Improving psychosocial support is vital to patient-centric care pathways for vulnerable groups. Mixed methods provide comprehensive evidence to inform integrated physical and mental health services.
