Longitudinal assessment of associations between food insecurity, antiretroviral adherence and HIV treatment outcomes in rural Uganda.

ABSTRACT: 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 CD4 T-cell count (<350?cells/?l). We used generalized estimating equations to estimate the associations, adjusting for socio-demographic and clinical variables.We followed 438 participants for a median of 33 months; 78.5% were food insecure at baseline. In adjusted analyses, food insecurity was associated with higher odds of ART nonadherence [adjusted odds ratio (AOR) 1.56, 95% confidence interval (CI) 1.10-2.20, P?
