A Multilevel Intervention in the Hunger Relief Network to Improve Diet Among Adults Experiencing Food Insecurity (SuperShelf)

Evaluate the health impact of an intervention targeting the hunger relief network and the clients with food insecurity it serves. The long-term goal of this work is to reduce nutrition-related health disparities by intervening on a system that serves individuals at high risk for chronic disease. In 2014, an estimated 14% of U.S. households experienced food insecurity (i.e., they lacked access to enough food for an active, healthy life for all household members). Large numbers of low-income, racial/ethnic minority, and immigrant families who experience food insecurity rely on a hunger relief network that includes food banks and food pantries. Pantry clients have demonstrated poor nutritional outcomes, high chronic disease rates, and dissatisfaction with the quality and cultural-appropriateness of food offered. Unlike other food assistance programs, there are currently no standards on the nutritional quality of pantry offerings, but recent work by our study team demonstrated the need to improve the healthfulness of hunger relief network inventory. We proposed an evaluation of a randomized, sustainable intervention in 8 intervention and 8 control pantries. We will enroll clients at baseline and follow them for 1 year to assess changes in overall diet quality (the primary outcome). Working with our food bank partners, the intervention at the pantry level targets the supply of nutritious foods. At the client level, the intervention targets healthy food demand. Measured outcomes include overall diet quality (the primary outcome), as assessed by the Healthy Eating Index-2015 (HEI), the nutritional quality of foods selected at the food shelf visit, and cardiovascular disease health (assessed by the American Heart Association's Life's Simple 7 scores). The study will also evaluate the impact of a multilevel intervention on the nutritional quality of pantry offerings. The study also aims to improve implementation of practices that promote a nutrition-focused hunger relief network.
