Prevalence and associated factors of TB co-morbidity among HIV sero-positive individuals in Shegaw Motta district hospital, Ethiopia

Abstract

Background: Tuberculosis (TB) is a major public health problem among people living with Human Immunodeficiency Virus (HIV) in resource-limited countries like Ethiopia. Up-to-date information regarding TB co-morbidity and determinant factors among HIV sero-positive individuals is lacking in the study area. Objective: This study aimed to determine the prevalence of TB co-morbidity and their determinants among HIV sero-positive individuals in Shegaw Motta district hospital. Methods: A cross-sectional study was conducted among 326 people living with HIV from February to April 2019, in Shegaw Motta district hospital. The systematic random sampling technique was used to select the study participants. Data were entered into the EpiData version 3.1 and analysis was done using SPSS version 20.0. Results: The prevalence of TB/HIV co-infection was 18.1%. TB/HIV patients whose drunk alcohol (AOR=2.36, 95% CI=1.07–5.19), BMI< 16 (AOR= 19.13, 95% CI=4.14–88.36), and BMI ranges between 16 and 18.5 (AOR=9.78, 95% CI=3.07–31.19), World Health Organization (WHO) clinical stage IV (AOR=23.02, 95% CI=3.76–140.97), WHO clinical stage III (AOR=14.36, 95% CI=3.50–58.92), and WHO clinical stage II (AOR=4.17, 95% CI=1.34–13.01), bedridden (AOR=13.79, 95% CI=5.44–34.95) and ambulatory functional status (AOR=5.30, 95% CI=1.87–15.05) were significant predictors for TB/HIV co-infection. Conclusion: The prevalence of TB among HIV sero-positive individuals is high. Determinant factors, including drinking alcohol, BMI, WHO clinical stage and functional status, were significant predictors for TB/HIV co-infections. Therefore, diagnosis of TB among sero-positive individuals should be strengthened in health institutions.
