Introduction: Unless patients know their HIV status, they cannot benefit from the availablerncare and treatment options. Therefore, various counseling and testing strategies are needed tornidentify more HIV infected patients.rnObjective: This study was conducted in March 2007 to assess acceptability of PIHCT and thernfactors influencing its uptake among TB patients in Addis Ababa.rnMethods: Institution-based, cross-sectional study was conducted and 423 TB patientsrninterviewed. A two stage sampling method was used for the selection of study subjects. In thernfirst stage of sampling, six health centers were selected by simple random sampling. In thernsecond stage of sampling, patients were systematically selected in each selected health center.rnResults: Most of the patients were initiated for HIV testing by their TB treatment supervisorrn402(98.5%). Among those who were initiated by their treatment supervisor for HIV testing,rn266(66.2%; 95%CI= 61.6-70.8) had under gone HIV testing. Adjusted correlates ofrnacceptability of PIHCT include younger age group (20-24) (AOR=3.0, 95% CI=1.2-8.1),rnprimary education (AOR=2.0, 95% CI=1.04-3.8), secondary and above education (AOR=1.9,rn95% CI=1.01-3.7), and recognition that any one should get tested for HIV (AOR=5.5, 95%rnCI=1.4-21.7). The reported barriers for acceptability of PIHCT include no risk perception forrnHIV infection 54(40.3%), tested before 53(39.3%), and fear of learning positive result 40rn(29.8%) of the study participants.rnviirnConclusion and Recommendation: The wide spread support, and evidence of highrnacceptability of PIHCT in this study holds significant promise for the control, prevention andrntreatment of both HIV/AIDS and TB. Concerted efforts to consolidate, sustain, and scale uprnPIHCT, however, should be accompanied by intensive IEC on TB /HIV.
