Factors associated with tuberculosis and human immunodeficiency virus co-infection in vulnerable populations

ABSTRACT Objective: To identify factors associated with tuberculosis and HIV co-coinfection in homeless people and those deprived of their liberty in Belo Horizonte, Minas Gerais, Brazil. Method: a cross-sectional, analytical study using data from the Notifiable Diseases/Tuberculosis Information System of Belo Horizonte, 2015 to 2022. The sociodemographic and clinical data of homeless people and people deprived of their liberty were described. Poisson regression was used to analyze the associated factors. Results: Drug use was a risk factor for coinfection in the street population. Being over 50 contributed 61% to this population’s reduced coinfection. The study did not show factors associated with coinfection in people deprived of liberty. Conclusion: The study identified the factors that increase the vulnerability of homeless people, thus helping to guide care for this young, drug-using population.
