Pilot Study of Capacity-oriented Intervention to Promote Food Security and Diet Quality Among Hispanics/Latinos

Pilot Intervention Study for Capacity-oriented Approaches to Food Security, Diet Quality, and Cardiovascular Disease Risk Among Hispanics/Latinos

Despite a large proportion exhibiting cardiovascular disease risk factors and experiencing food insecurity, U.S. Hispanics/Latinos demonstrate low cardiovascular mortality, which may indicate existing capital (e.g., assets) protecting health and diet. The goal of this study is to evaluate the feasibility and short-term efficacy of a pilot intervention aimed at improving diet quality through strengthening food- and diet-related capital and food security among low-income, Hispanic/Latino adults in San Diego, California. The pilot intervention will be integrated into an existing local health or nutrition program serving low-income Hispanic/Latino adults. Participants will be asked to:

• Complete questionnaires before and after the intervention
• Engage in nutrition education activities
• Engage in food access-related activities
