There is limited evidence on the short- and long-term mortality rate in people receiving antiretroviral therapy and coinfected by tuberculosis in sub-Saharan Africa, where the burden of coinfection is highest.Purpose: This study aimed to compare mortality among HIV positives with and without tuberculosis coinfection receiving antiretroviral therapy in Addis Ababa, Ethiopia.Methods: HIV positives’ medical records were reviewed between 2011 to 2018 and identified 7038 HIV-positive adults enrolled for antiretroviral therapy in Addis Ababa. The outcome of interest for this study was death. A parametric Gompertz regression model was applied to compare mortality between HIV with tuberculosis coinfection versus HIV without tuberculosis.Results: Overall, 1123 (15.96%, 95% CI: 15.11– 16.83%) individuals with HIV had tuberculosis coinfection at antiretroviral therapy enrollment. After adjusting for age, sex, education, marital status, cotrimoxazole therapy, body mass index, baseline CD4 cell count, and year in ART enrollment, HIV positives with tuberculosis coinfection had more than twice a higher overall mortality risk than HIV positives without tuberculosis coinfection (AHR: 2.53; 95% CI 1.63– 3.91, p < 0.001).Conclusion: This large retrospective cohort study reveals significantly higher mortality in HIV and tuberculosis coinfected group. This suggests the need for enhanced utility of integrated HIV and tuberculosis health services in sub-Saharan Africa where tuberculosis prevalence is highest.Keywords: antiretroviral therapy, HIV, coinfections, death
