P06-030 - Double Up Food Bucks Participants Have Higher Fruit and Vegetable Intake than Their Peers, but Participation Does Not Increase Intake

8:00 AM – 3:00 PM

Objectives: This study used a natural experiment to test whether participation in a farmers market (FM) incentive program, Double Up Food Bucks (DUFB), lead to increased fruit and vegetable (FV) consumption in Supplemental Nutrition Assistance Program (SNAP) recipients.

A longitudinal telephone survey of a cohort of SNAP recipients was conducted, with measurements before the FM season, during the FM season, and at the end of the FM season. At baseline, participants were informed of the availability of DUFB at their local FM and follow-up surveys measured use of DUFB. Fruit and vegetable consumption was tested at each time point using the Behavioral Risk Factor Surveillance System fruit and vegetable module. A linear mixed model approach was used to examine the effect of using DUFB at any time on FV consumption and the difference in FV consumption among those who used and those who did not use DUFB.

At baseline, 212 participants were recruited, primarily white 79.6% (n=168), women 77.3% (n=163), with an average age of 43.53 years ± 15.63 (standard deviation). There were no significant differences in demographics between those who completed follow up (n=123, 58% retention rate) and those who didn't. Of these 123 participants, 35 chose to use the DUFB program. Our models found a significant effect for DUFB use (p<0.001) with DUFB use associated with higher FV intake at all time points. There was also a significant effect for time (p=0.033) with FV intake decreasing over time in both groups. There was not a significant effect for DUFB use across time.

These results do not support the hypothesis that DUFB results in increased FV consumption. Rather, our results show that SNAP recipients who choose to use the program have higher FV consumption frequency even before program use. The decrease in FV consumption frequency over time in both groups may be due to response shift bias. Some caution should be used when interpreting these results because of the low retention rate and small number of individuals who chose to use the program.
