Objective:
To explore perceptions of program impact among Double Up Food Bucks participants in Oregon.
Methods:
Data were collected from 1,223 Double Up Food Bucks participants at 42 Oregon farmers' markets. Chi-square tests of independence and logistic regressions were used to examine associations among key variables.
Results:
Most participants reported buying more fruits and vegetables (FVs) (91.0%), trying new FV types (82.2%), eating less processed food (69.8%), having more food available at home (81.1%), and perceiving improvements in health (87.9%). Perceptions of affordability were higher among younger adults (P < 0.001) and households with 3-5 people (P = 0.02), with children (P < 0.001), and without chronic disease (P = 0.003). Perceptions of increased FV purchases were higher in households with children (P = 0.009) and reported overall health improvements were higher among non-White participants (P = 0.04). Perceptions of increased FV purchases and affordability were associated with other positive program outcomes.
Conclusions And Implications:
Participants may perceive barriers to purchasing FVs from farmers' markets, which are not fully addressed by the increased purchasing power from a FV incentive. Targeted redesign, outreach, and education may improve program experiences among groups with less positive perceptions. Further research to identify explanations for variation in program experience is needed.
