ABSTRACT
Background: Tuberculosis and diabetes mellitus are major public health challenges worldwide. The two scourges have bidirectional relationship with high morbidity and mortality. Objective: The present study was conducted to determine the prevalence of diabetes mellitus and identify related factors in patients with tuberculosis. Methods: A cross-sectional study was conducted in 11 tuberculosis screening and treatment centers in Lubumbashi (DRC) from September to December 2022. Adult patient with a positive smear for tuberculosis were systematically screened for diabetes mellitus. Demographic characteristics, history and symptomatology were the variables of interest. Data was entered using Microsoft Excel software. STATA 16 software was used for analysis. Results: A total of 255 tuberculosis patients were recruited and the prevalence of diabetes mellitus among these patients was 11.4% (ie, 29 out of 255). After uni and multivariate logistic regression, a BMI ≤ 18.5 Kg/m2, lack of employment, polyuria and intense thirst were the factors associated with diabetes mellitus in tuberculosis patients. Conclusion: The prevalence of diabetes mellitus in smear positive tuberculosis patients in the present study was higher than the one observed in Central Africa.
