Abstract

OBJECTIVE

To evaluate the effect of the Utah Double Up Food Bucks (DUFB) program on fruit and vegetable (F&V) intake and food security status among Supplemental Nutrition Assistance Program (SNAP) recipients.

METHODS

Data were collected in 2015, using a before-and-after study design. At the farmers' market, a convenience sample of SNAP recipients was recruited for a survey and a 4-week telephone follow-up survey. Differences between the 2 surveys in food security and F&V intake were tested using the Wilcoxon signed-rank test.

RESULTS

Follow-up surveys were completed with 138 (40%) of the 339 baseline participants. Median F&V consumption increased from 2.82 times per day to 3.29 times per day (median, interquartile range 1.48-3.99 and 3.28-5.02, respectively, P = .002). The percentage of DUFB participants who were food secure increased by 15% (P = .001).

CONCLUSIONS AND IMPLICATIONS

The present results add to the growing literature indicating farmers' market incentives are associated with increased F&V consumption and decreased food insecurity. Although more research is needed, farmers' market incentives may be an effective area of policy intervention.

摘要

目的

评估犹他州双倍食品券计划(DUFB)对补充营养援助计划(SNAP)受益人的水果和蔬菜摄入量以及粮食安全状况的影响。

方法

采用前后对照研究设计于2015年收集数据。在农贸市场,招募了一个SNAP受益人的便利样本进行调查,并进行为期4周的电话随访调查。使用Wilcoxon符号秩检验来检验两次调查在粮食安全和水果与蔬菜摄入量方面的差异。

结果

339名基线参与者中有138名(40%)完成了随访调查。水果和蔬菜的日均摄入量中位数从每天2.82次增加到每天3.29次(中位数,四分位间距分别为1.48 - 3.99和3.28 - 5.02,P = 0.002)。粮食安全的DUFB参与者比例增加了15%(P = 0.001)。

结论与启示

目前的研究结果进一步丰富了现有文献,表明农贸市场激励措施与水果和蔬菜摄入量增加以及粮食不安全状况改善相关。尽管还需要更多研究,但农贸市场激励措施可能是政策干预的一个有效领域。
