- W2894842546 abstract "Objective: The objective of this study was to assess the effectiveness of a routine multivitamin supplementation program for adults living with HIV in Tanzania. Design: We conducted a retrospective cohort study of 67 707 adults enrolled in the Dar es Salaam HIV care and treatment program during 2004–2012. Methods: The Dar es Salaam HIV care and treatment program intended to provide all adult patients with multivitamin supplements (vitamins B-complex, C, and E) free of charge; however, intermittent stockouts and other implementation issues did not afford universal coverage. We use Cox proportional hazard models to assess the time-varying association of multivitamin supplementation with mortality and clinical outcomes. Results: The study cohort contributed 41 540 and 129 315 person-years of follow-up time to the antiretroviral therapy (ART)-naive and ART-experienced analyses, respectively. Among 48 207 ART-naive adults, provision of multivitamins reduced the risk of mortality [adjusted hazard ratio (aHR): 0.69; 95% confidence interval (CI): 0.59–0.81], incident tuberculosis (TB) (aHR: 0.83; 0.76–0.91), and meeting ART eligibility criteria (aHR: 0.78; 95% CI: 0.73–0.83) after adjustment for time-varying confounding. Among 46 977 ART-experienced patients, multivitamins reduced mortality (hazard ratio: 0.86; 95% CI: 0.80–0.92), incident TB (aHR: 0.78; 95% CI: 0.73–0.84), and immunologic failure (aHR: 0.70; 95% CI: 0.67–0.73). The survival benefits associated with provision multivitamins appeared to be greatest during the first year of ART and declined over time (P value <0.001). Conclusion: Multivitamin supplementation appears to be a simple, effective, safe, and scalable program to improve survival, reduce incidence of TB, and improve treatment outcomes for adult HIV patients in Tanzania." @default.
