Predictors of tuberculosis infection among adults visiting anti-retroviral treatment center at east and west Gojjam, northwest, Ethiopia, 2017
Abstract
Abstract Background Tuberculosis is a serious health risk, for people living with human immune deficiency virus worldwide, and the burden of TB/HIV infection is still high in Ethiopia in particular. Therefore, the aim of this study was to determine the predictors of tuberculosis infection among adults visiting anti-retroviral treatment center in East and West Gojjam, northwest, Ethiopia. Methods Institution based unmatched case-control study was employed to determine the predictors of tuberculosis infection among adults visiting anti-retroviral treatment center in east and west Gojjam, Northwest, Ethiopia from March 7–April 15, 2017. Just about 552 participants were participated in the study (139 Cases and 413 controls). Cases were confirmed with active TB and infected with HIV, and controls were HIV positive adults with non-TB. All cases in each health facility who confirmed by acid-fast bacilli, culture and gene expert were considered as TB positive. However, controls were selected by using simple random sampling technique through the above diagnostic criteria and the data were collected with Face to face interview as well as patient medical record were utilized, and the quality of the data were assured, checked, coded, cleaned and entered in EPI-Data version 3.1 and exported to SPSS version 20 for the analysis. Result Of the total sample (556), just about 552(99.2%) were participated in the study. 47.5% were females and 58.9% were rural dweller. Behavioral and modifiable biological risk factors: alcohol users (AOR = 2.33; 95%CI:1.34,4.07), BMI < 18.5 kg/m2 (AOR = 3.03;95%CI:1.79,5.14), CD4 count ≤200 cells/μl (AOR = 2.34;95%CI:1.89,2.79) and between 201 and 499 cells/μl (AOR = 2.63; 95%CI: 1.01,6.84), bedridden and ambulatory (AOR = 3.3;95%CI:1.70,6.29 and AOR = 8.2;95%CI:4.34,15.64), respectively. TB history in the family (AOR = 3.00; 95%CI: 1.57, 5.74) were predictors for TB infection. Taking CPT (AOR = 0.36; 95%CI: 0.21, 0.62) and having early WHO clinical stage I or II (AOR = 0.34; 95%CI: 0.20, 0.56) had protective effect against TB infection. Conclusion From this study, it has been concluded that alcohol users, BMI < 18.5 kg/m2, CD4 count < 499 cells/μl, bedridden and ambulatory and TB history were predictors for TB-HIV co-infected adults. Strengthen screening more frequently, CPT Prophlaxysis and treated promptly important to reduce TB co-morbidity.
