Systems Science Approaches to Improve Access to Healthier Foods: The FRESH Trial

INTERVENTIONAL
Conditions
Summary
Working with independently owned restaurants, a common source of calorie-rich, nutrient-poor foods in predominantly minority, low-income urban neighborhoods, has the potential to improve dietary quality, and contribute to cancer prevention. This study uses systems science approaches to improve access to healthier foods in independently owned restaurants by: 1) testing the effects of a novel intervention called FRESH (Focus on Restaurant Engagement to Strengthen Health) on dietary quality, health indicators and other outcomes in African American and Latin communities, and 2) developing a system dynamics model to allow stakeholders to virtually test FRESH strategies in their own communities. The resulting restaurant intervention simulation model offers potential cost savings from avoided trial-and-error testing, and will support community-based cancer prevention.
Eligibility
Inclusion Criteria4
- Adult (18-75 years)
- Regular restaurant customer (e.g., visits the specified restaurant at least 1x/week)
- Live in a household of at least 2 persons (criterion intended to provide a more stable sample, and to reduce loss to follow-up)
- Current resident of study neighborhood
Exclusion Criteria2
- Anticipate moving out of Baltimore or District of Columbia metropolitan area in the next 18 months
- Pregnant (due to changes in diet, weight and body composition)

Interventions
FRESH is a restaurant-based intervention in low-income neighborhoods in Baltimore, MD and the Washington, District of Columbia metro area that aims to improve the healthy prepared-food environment for consumers, informed by community members and other stakeholders. FRESH intervention components include food preparation, food access and procurement, and consumer nutrition environment. Activities will take place over 16 months, and include training restaurant chefs to use healthier cooking methods, partnering with restaurant suppliers to offer healthier ingredients, and offering point-of-purchase promotions to educate customers on the healthier promoted food options. Intervention staff will form strong relationships with restaurant owners and chefs via in-person visits at least twice a month. Data from the intervention trial will inform the development of a system dynamics simulation model that will allow stakeholders to test new policy ideas prior to implementation.
