INTRODUCTION Policy, systems, or environmental (PSE)-focused interventions can help address barriers to farmers market use among shoppers with low-income. The objective of this scoping review was to characterize potential PSE interventions to increase farmers market use among shoppers with low-income, distinguishing potential determinants and outcome-based strategies across each level. METHODS Systematic searches were used to identify 7,019 unique records. After screening, 86 studies were synthesized narratively. Study samples included market staff, vendors, patrons, potential patrons, community stakeholders, and others. RESULTS The majority used a cross-sectional design (70%) and collected quantitative data (75%). Twenty-three potential determinants or strategies to increase farmers market use were identified and categorized as follows: food assistance program availability; food assistance program implementation; farmers market marketing and familiarity; market location, hours, and accessibility; and farmers market experience and culture. DISCUSSION Findings suggest that providing food assistance programs at farmers markets is a valuable first step that can be followed by additional PSE interventions to improve patronage among shoppers with low-income. CONCLUSIONS AND IMPLICATIONS Future research can further assess potential determinants that have underexplored relationships with market use. Findings outline a variety of strategies that can be used by community-based nutrition professionals to support PSE initiatives at farmers markets.
