    Food insecurity is associated with morbidity and patterns of healthcare utilization among HIV-infected individuals in a resource-poor setting
    (AIDS (London, England), 2012) Weiser, Sheri D.; Tsai, Alexander C.; Gupta, Reshma; Frongillo, Edward A.; Kawuma, Annet; Senkungu, Jude; Hunta, Peter W.; Emenyonue, Nneka I.; Mattson, Jennifer E.; Martin, Jeffrey N.; Bangsberg, David R.
    We undertook a longitudinal study in rural Uganda to understand the association of food insecurity with morbidity and patterns of healthcare utilization among HIV-infected individuals enrolled in an antiretroviral therapy program. Longitudinal cohort study. Participants were enrolled from the Uganda AIDS Rural Treatment Outcomes cohort, and underwent quarterly structured interviews and blood draws. The primary predictor was food insecurity measured by the validated Household Food Insecurity Access Scale. Primary outcomes included health-related quality of life measured by the validated Medical Outcomes Study-HIV Physical Health Summary (PHS), incident self-reported opportunistic infections, number of hospitalizations, and missed clinic visits. To estimate model parameters, we used the method of generalized estimating equations, adjusting for sociodemographic and clinical variables. Explanatory variables were lagged by 3 months to strengthen causal interpretations.

    Longitudinal assessment of associations between food insecurity, antiretroviral adherence and HIV treatment outcomes in rural Uganda
    (AIDS (London, England), 2014) Weiser, Sheri D.; Palar, Kartika; Frongillo, Edward A.; Tsai, Alexander C.; Kumbakumba, Elias; dePee, Saskia; Hunta, Peter W.; Ragland, Kathleen; Martin, Jeffrey; Bangsber, David R.
    Food insecurity is a potentially important barrier to the success of antiretroviral therapy (ART) programs in resource-limited settings. We undertook a longitudinal study in rural Uganda to estimate the associations between food insecurity and HIV treatment outcomes. Longitudinal cohort study. Participants were from the Uganda AIDS Rural Treatment Outcomes study and were followed quarterly for blood draws and structured interviews. We measured food insecurity with the validated Household Food Insecurity Access Scale. Our primary outcomes were: ART nonadherence (adherence <90%) measured by visual analog scale; incomplete viral load suppression (>400 copies/ml); and low CD4รพ T-cell count (<350 cells/ml). We used generalized estimating equations to estimate the associations, adjusting for socio-demographic and clinical variables.
