The Association Between Food Insufficiency and HIV Treatment Outcomes in a Longitudinal Analysis of HIV-Infected Individuals in New York City.

Abstract

To date, there have been few longitudinal studies of food insecurity among people living with HIV (PLWH). Food insufficiency (FI) is one dimension of the food insecurity construct that refers to periods of time during which individuals have an inadequate amount of food intake because of limited resources. The aim of this analysis was to examine the relationship between FI and HIV treatment outcomes among HIV-infected individuals in New York City (NYC). Associations between FI ("consistent"--food insufficient on both of the last 2 assessments, "inconsistent"--food insufficient on 1 of the last 2 assessments, or neither) and clinical indicators of HIV disease progression (viral load > 200 copies per milliliter, CD4 count < 200 cells per cubic millimeter) were analyzed for NYC Ryan White Part A food and nutrition program clients who were matched to the NYC HIV Surveillance Registry and completed 2 FI assessments between November 2011 and June 2013. Among 2,118 PLWH in food and nutrition programs, 61% experienced consistent FI and 25% experienced inconsistent FI. In multivariate analyses controlling for sociodemographic characteristics, consistent FI was independently associated with unsuppressed viral load (adjusted odds ratio = 1.6, confidence interval: 1.1 to 2.5). Consistent FI was only associated with low CD4 counts at the bivariate level. Future studies should examine biological, structural, and psychosocial factors that may explain the relationship between FI and HIV treatment outcomes to inform intervention development. Persistent FI among food and nutrition program clients suggests that services are needed to address underlying needs for financial stability (eg, vocational counseling) for PLWH.
