Food Insecurity: A Key Structural Barrier to HIV/AIDS Care
Location(s): United States
Food insecurity affects 40 million households in the U.S, and the prevalence has been rising since 1999. There is growing recognition that food insecurity may negatively effect HIV disease progression and the effectiveness of antiretroviral treatment (ART), but there is little data to support this. Among HIV-infected urban poor individuals, competing demands between resources spent on food versus medical care may also lead to missed clinic appointments and decreased use of ART. Similarly, while data from sub-Saharan Africa shows that food insecurity is an important cause of risky sexual practices, there are no data on this issue from domestic populations. Without clear data documenting how food insecurity impacts upon HIV outcomes, access to care, and HIV transmission risk behaviors, it is unclear to what extent resources dedicated to HIV management should also be invested in ensuring safe access to food. Food supplementation is a potentially important adjunct to HIV care. To address these gaps, we propose a 1-year study in San Francisco with the following specific aims: 1) Determine the impact of food insecurity on adherence to ART medication regimens and HIV treatment outcomes among participants enrolled in the Research on Access to Care in the Homeless (REACH) cohort. 2) Determine the impact of food insecurity on access to health care and initiation of ART among REACH participants; and 3) Determine the association between food insecurity and high-risk sexual behaviors among REACH participants and whether these associations differ by gender.
This study is innovative in that it will provide the first quantitative and longitudinal assessment of the effects of food insecurity on HIV health behaviors and health outcomes in the U.S, and will be the first to explore the social and behavioral mechanisms through which food insecurity may negatively impact care. This proposal will provide the preliminary data for the development of an intervention study in San Francisco of the role of targeted food assistance on HIV health outcomes, use of health services, and transmission risk, which will be proposed as an NIH-funded grant at the end of the study period. The results of this research may help argue for better integration of food aid services and HIV care services among people living with HIV/AIDS in San Francisco and elsewhere.
