Grady FVRx program impact on dietary practices and food security: A pre-post evaluation Público

Abstract
Objective
Food security affects dietary practices, which in turn influences chronic disease risk. We sought to identify the effect of the Grady Fruit and Vegetable Prescription (FVRx) program for low income patients on dietary practices and food security status as well as to characterize variations in effect by baseline food security status.
Methods
Analysis was done using pre- and post- program data from the 2018 and 2019 cohorts of Grady FVRx program. The USDA Healthy Eating Index (HEI) was used as a template to create scores for healthy food and beverage consumption, healthy purchase practices and food resource management. Food security status was assessed using the USDA 6-item household food security scale. A chi-square test was used to determine the association between baseline food security and direction of change in end line food security status. Poisson regression models were used to determine change in fruit and vegetable intake, while linear regression models were used to determine change in dietary practice scores.
Results
Participants experienced significant changes in food security status, fruit and vegetable intake, healthy food and beverage consumption, healthy purchase choices, and food resource management. At end line, 34% of participants had increased food security while 56% maintained their baseline status. Change in food security was significantly associated with baseline food security status, with 67% and 58% of very low and low food secure participants respectively reporting improved food security at end line (p<0.0001). Fruit and vegetable intake increased by 0.13(95% CI - 0.07,0.19) and 0.10(95%CI - 0.04,0.14) respectively. Dietary practice scores increased as follows: healthy food consumption [0.38 (95%CI - 0.23,0.51)], healthy beverage consumption [0.27 (95%CI - 0.11,0.36)], healthy purchase choices [0.59 (95%CI - 0.44,0.67)] and food resource management [0.61 (95%CI - 0.44,0.65)]. Magnitude of change in dietary practice score was significantly lower among very low and low food insecure participants.
Conclusion
Grady’s FVRx program effected improved food security and dietary practices among participants. Baseline food security status impacted the magnitude of change in dietary practices. More research is necessary to understand the specific needs of food insecure populations in order to develop effective nutrition interventions for them.
