Background: MDR-TB (Multidrug Resistant tuberculosis) remains a major public health concern, especially in high-burden countries like Nepal. While individual risk factors are known, the cumulative impact of cardiometabolic on MDR-TB is not well understood. Methods and Findings: A health-facility-based, age- and sex-matched 1:2 case-control study will be conducted at DR-TB (Drug Resistant Tuberculosis) treatment centers in Gandaki Province, Nepal. MDR-TB patients (cases) and DS-TB patients (controls) will be enrolled. Cases will be defined as adults (≥18 years) with confirmed MDR-TB; controls will be adults with sputum-positive DS-TB (Drug Sensitive Tuberculosis). Data on sociodemographics, cardiometabolic risk factors (alcohol, tobacco, BMI, hypertension, diabetes), TB literacy, and treatment history will be collected using a structured, pretested questionnaire by trained medical officers. Data will be analyzed using SPSS v25. Binary logistic regression will be used to assess associations between risk factors and MDR-TB. Ethical approval will be obtained from the NHRC, and written informed consent will be obtained from all participants.
