Background: Tuberculosis is the leading cause of deaths among HIV patients. In this study, we estimated the prevalence of pulmonary tuberculosis (PTB) and identified the factors/co-morbidities associated with active PTB in HIV-infected people visiting the national public health laboratory to assess their eligibility to receive highly active antiretroviral therapy. Methods: A cross-sectional study was conducted to measure the prevalence of pulmonary tuberculosis. Data on probable risk factors in patients with and without PTB were compared, calculating the odds ratio as a measure of association. Factors showing significant association in univariate analyses were included in a stepwise backward logistic regression model to adjust for confounding. Results: The prevalence of pulmonary tuberculosis was 32.4 % (95% confidence interval (CI) 30.25–34.56). In the univariate analysis, patients with PTB were more likely to be older, married, and have a longer duration since the diagnosis of HIV, diarrhoea, parasitic infection, lower CD4 T-cell counts, and lower CD4/CD8 ratio. However, the backward stepwise logistic regression revealed that only the CD4 T-cell count < 200/μL (AOR 11.69, 95% CI 6.23–21.94), CD4 T-cell count 200–350/μL (AOR 2.52, 95% CI 1.30–4.89), diarrhoea (AOR 2.77, 95% CI 1.78–4.31), parasitic infection (AOR 3.34, 95% CI 2.02–5.50) and ‘sex with partner’ as probable modes of transmission (AOR 0.44, 95% CI 0.20–0.93) were independently associated with pulmonary tuberculosis. Conclusion: A high prevalence of pulmonary tuberculosis was observed. Participants with tuberculosis were significantly more likely to have lower CD4 counts, diarrhoea, and parasitic infections. HIV treatment programmes should consider these factors for better outcomes.
