A Mixed-Methods Evaluation of a SNAP-Ed Farmers' Market-Based Nutrition Education Program.

ABSTRACT

OBJECTIVE: Evaluate the effectiveness of the Stellar Farmers' Market program. DESIGN: Mixed methods including focus groups and a quasi-experiment comparing a control group of market shoppers who had never attended a class, participants attending 1 class, and participants attending ≥ 2 classes. SETTING: Eighteen farmers' markets in New York City. PARTICIPANTS: A total of 2,063 survey respondents; 47 focus group participants. INTERVENTION Farmers' market-based nutrition education and cooking classes paired with vouchers for fresh produce. MAIN OUTCOME MEASURES: Attitudes, self-efficacy, and behaviors regarding fruit and vegetable (FV) preparation and consumption. ANALYSIS: Bivariate and regression analysis examined differences in outcomes as a function of number of classes attended. Qualitative analysis based on a grounded theory approach. RESULTS: Attending ≥ 1 classes was associated with more positive attitudes toward consuming FV; attending ≥ 2 classes was associated with greater FV consumption and higher self-efficacy to prepare and consume produce. Respondents attending ≥ 2 classes consumed almost one-half cup more FV daily than others. These associations remained after controlling for age, race/ethnicity, education, and gender. CONCLUSIONS AND IMPLICATIONS Offering nutrition education and cooking classes at farmers' markets may contribute to improving attitudes, self-efficacy, and behaviors regarding produce preparation and consumption in low-income populations.
