BackgroundThe U.S. Department of Agriculture (USDA) defines food insecurity as a lack of consistent access to enough food for an active and healthy life. A review of the literature indicates that there are only few studies on food insecurity and people living with human immunodeficiency virus (HIV) in the United States, despite it being one of the most basic physiological need. Here, we aimed to examine the association between food insecurity and viral load suppression in people with HIV on antiretroviral therapy (ART) at an HIV primary care practice.MethodsThis was a cross-sectional study conducted at an urban university hospital HIV primary care practice in Brooklyn, New York. It included patients seen during a six month period, from July 1 until December 31, 2018, that were found to have an unsuppressed viral load while reporting being on ART. We defined unsuppressed viral load as viral load >200 copies/milliliters. Food security was measured with the Household Food Insecurity Access Scale (HFIAS), a questionnaire by USAID’s Food and Nutrition Technical Assistance Program, which has demonstrated cross-cultured validity. It categorized patients into four groups: food secure and mildly, moderately or severely food insecure. Patient were contacted in clinic during their appointment or by telephone survey.ResultsA total of 145 patients were found to have an unsuppressed viral load while on ART, with 54 patients (37%) reporting food insecurity. Based on HFIAS’s classification, 44 patients (30%) reported mild or moderate food insecurity, and 10 patients (7%) reported severe food insecurity. The study population demographics was 86% African American or blacks, 12% Hispanics and 2% of other race. Seventy-three patients (50%) also reported receiving benefits from New York’s Supplemental Nutrition Assistance Program.ConclusionFood insecurity can be associated with unsuppressed viral load and was found in over one-third of our study population, with half relying on food assistance programs. It represents a complex problem fundamentally connected to issues such as poverty and unstable housing, which can negatively impact patient engagement and retention in care. Our findings highlight the importance of integrating food and social services into HIV programs, especially in lower-income populations.Disclosures All authors: No reported disclosures.
