Objective: To delineate the association between baseline socioeconomic status (SES) indicators and mortality and lost to follow-up (LTFU) in a cohort of HIV-infected individuals enrolled in antiretroviral therapy (ART) in urban Uganda.

Design: Retrospective cohort study nested in an antiretroviral clinic-based cohort.

Methods: SES indicators including education, employment status, and a standardized wealth index, and other demographic and clinical variables were assessed at baseline among ART-treated patients in a clinic-based cohort in Kampala, Uganda. Confirmed mortality (primary outcome) and LTFU (secondary outcome) were actively ascertained over a 4-year follow-up period from 2005 to 2009.

Results: Among 1763 adults [70.5% female; mean age, 36.2 years (SD = 8.4)] enrolled in ART, 14.4% (n = 253) were confirmed dead and 19.7% (n = 346) were LTFU at 4-year follow-up. No formal education [adjusted odds ratio (AOR) 1.76; 95% confidence interval (CI): 1.19 to 2.59], having fewer than 6 dependents (AOR 1.39; 95% CI: 1.04 to 1.86), unemployment (AOR 1.98; 95% CI: 1.48 to 2.66), and housing tenure index score (a component of the wealth index) (AOR 1.11; 95% CI: 1.00 to 1.23) were significantly associated with confirmed mortality at 4 years. SES indicators were not associated with LTFU at 4 years.

Conclusions: Baseline SES indicators, including education, number of dependents, employment status, and components of a standard wealth index may indicate long-term vulnerability to mortality in patients with HIV/AIDS, despite uniform access to ART. Future studies delineating the pathways through which poverty and limited assets affect clinical outcomes may lead to more effective HIV interventions in low-resource settings.
