Abstract
Non-adherence to treatment remains a major obstacle to efficient tuberculosis control in developing countries. The
dual infection of Tuberculosis and HIV presents further adherence problems because of high pill burden and adverse effects. This poses
a risk of increased multi-drug resistant TB. However, the prevalence of non-adherence and its associated factors have not been studied
in these patients in Uganda.
Objectives: To determine the prevalence and factors associated with non-adherence to anti-TB drugs among TB/HIV co-infected
patients in Mbarara hospital.
Methods: A cross-sectional study with qualitative and quantitative data collection methods was conducted among TB/HIV coinfected
adults in Mbarara hospital from January to March 2008. Consecutive sampling was used to select 140 participants. Adherence
was assessed over a 5-day period prior to the interview using patients self-reports. Data was collected using an interviewer administered
questionnaire. Qualitative data was collected through key informant interviews using a topic guide and was analyzed manually.
Quantitative data was analyzed using STATA version 8. Logistic regression was used to determine factors associated with nonadherence.
Results: The prevalence of non-adherence was 25% (95% CI=17.8-32%). Being on continuous phase of the TB regimen was
significantly associated with non-adherence (OR=6.24, p<0.001). Alcohol consumption, being on antiretroviral therapy and smoking
confounded the relationship between stage of the TB regimen and non-adherence.
Conclusion: The prevalence of non-adherence was high. Patients that are on continuous phase of TB treatment should be supported
to continue taking their drugs. In addition, patients that drink alcohol; smoke and those not on ART should be targeted with
interventions to improve adherence.
