The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) provides participants seasonal Farmers' Market Nutrition Program (FMNP) vouchers to purchase fruits and vegetables (FV) at farmers' markets and monthly cash value vouchers (CVV) redeemable at farmers' markets. Despite the promise of FMNP vouchers and CVV for improving FV access among WIC participants, voucher redemption rates are low. This study evaluated WIC Fresh Start (WFS), a theory-driven, web-based lesson to promote FV intake, the redemption of CVV at farmers' markets, FMNP voucher redemption, and farmers' market-related knowledge, attitudes, and skills among women enrolled in WIC.
The lesson was evaluated in a four-arm randomized controlled trial. The setting was a large New Jersey-based WIC agency located in a densely populated, urban area. Participants ( = 744) were stratified based on FMNP voucher receipt and randomized to receive the WFS lesson or WIC online existing health education. Lesson effects on targeted outcomes were examined at posttest (2 weeks after the lesson) and 3 and 6 months after posttesting.
Receipt of the WFS lesson was associated with FMNP voucher redemption (in the subset of participants preferring to speak Spanish); improvements in knowledge of the FMNP, locally grown seasonal items, seasonal items found at farmers' markets in July, WIC-authorized farmers' markets and food- and farmers' market-specific knowledge; ever having purchased and intentions to purchase FV at a farmers' market; FV food safety and preparation skills; and modest gains in the redemption of CVV at farmers' markets. FV intake did not differ over time by trial arm.
Findings aid understanding of effective approaches to promote farmers' market use and farmers' market-related knowledge and skills among WIC participants. Further research is needed to explore factors that may explain the lack of lesson effects on FV intake.

妇女、婴儿和儿童特别补充营养计划（WIC）为参与者提供季节性农贸市场营养计划（FMNP）代金券，用于在农贸市场购买水果和蔬菜（FV），以及每月可在农贸市场兑换的现金价值代金券（CVV）。尽管FMNP代金券和CVV有望改善WIC参与者获取FV的机会，但代金券兑换率较低。本研究评估了WIC Fresh Start（WFS），这是一个基于理论的网络课程，旨在促进FV摄入量、在农贸市场兑换CVV、FMNP代金券兑换，以及提升参加WIC的女性对农贸市场相关知识、态度和技能。
该课程在一项四臂随机对照试验中进行评估。研究地点是新泽西州一个位于人口密集市区的大型WIC机构。参与者（n = 744）根据是否收到FMNP代金券进行分层，并随机分为接受WFS课程或WIC在线现有健康教育。在课程后测（课程结束后2周）以及后测后3个月和6个月时，考察课程对目标结果的影响。
接受WFS课程与FMNP代金券兑换（在倾向说西班牙语的参与者子集中）相关；在FMNP知识、当地种植的季节性产品、7月农贸市场的季节性产品、WIC授权的农贸市场以及特定于食品和农贸市场的知识方面有所改善；曾经在农贸市场购买FV以及有在农贸市场购买FV的意向；FV食品安全和烹饪技能；以及在农贸市场兑换CVV方面有适度提高。各试验组的FV摄入量随时间没有差异。
研究结果有助于理解促进WIC参与者使用农贸市场以及与农贸市场相关知识和技能的有效方法。需要进一步研究以探索可能解释课程对FV摄入量缺乏影响的因素。
