This quasi-experimental pilot study explored farmers' market use among Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) participants and the effects of previous Farmers' Market Nutrition Program participation on farmers' market use. African-American women who were pregnant and enrolling in WIC in Washington, DC (n=71), and Charlotte, NC (n=108), participated in the study. Surveys were completed in May and June 2007 measuring farmers' market use, barriers to farmers' market use, previous Farmers' Market Nutrition Program participation, previous redemption of Farmers' Market Nutrition Program vouchers, and dietary consumption. Women in Washington, DC, might have previously participated in the Farmers' Market Nutrition Program, while women in Charlotte had no previous Farmers' Market Nutrition Program participation. Analyses included descriptive, chi2 statistic, analysis of variance, and unadjusted and multiple logistic regression. Participants' average age was 24 years, average education was 12.2 years, and average daily fruit/vegetable consumption was 7.5 servings. Participants in Charlotte and Washington, DC, without previous Farmers' Market Nutrition Program participation had similar farmers' market use rates (32.4% and 40%, respectively); those with previous Farmers' Market Nutrition Program participation in Washington, DC, had higher farmers' market use rates (61%) (P=0.006). Previous participation in the Farmers' Market Nutrition Program (odds ratio [OR]: 3.30; 95% confidence interval [CI]: 1.57 to 6.93), previous redemption of Farmers' Market Nutrition Program vouchers (OR: 4.96; CI: 2.15 to 11.45), and higher fruit/vegetable consumption (OR: 2.59; CI: 1.31 to 5.12) were associated with farmers' market use. Controlling for city, women who previously redeemed Farmers' Market Nutrition Program vouchers were more likely to use a farmers' market (OR: 6.90; CI: 1.54 to 31.00). Commonly reported barriers were lack of farmers' markets close to home and lack of transportation to farmers' markets. Women who received and redeemed Farmers' Market Nutrition Program vouchers were much more likely to purchase fruits/vegetables at farmers' markets. Future research to explore barriers and incentives for farmers' market use among WIC participants in urban and rural settings is warranted.
这项准实验性试点研究探讨了妇女、婴儿和儿童特别补充营养计划（WIC）参与者对农贸市场的使用情况，以及之前参与农贸市场营养计划对农贸市场使用的影响。在华盛顿特区（n = 71）和北卡罗来纳州夏洛特市（n = 108）怀孕并参加WIC的非裔美国妇女参与了该研究。2007年5月和6月完成了调查问卷，内容包括对农贸市场的使用情况、使用农贸市场的障碍、之前参与农贸市场营养计划的情况、之前对农贸市场营养计划代金券的兑换情况以及饮食消费情况。华盛顿特区的妇女可能之前参与过农贸市场营养计划，而夏洛特市的妇女之前没有参与过农贸市场营养计划。分析包括描述性统计、卡方统计、方差分析以及未调整和多元逻辑回归。参与者的平均年龄为24岁，平均受教育年限为12.2年，平均每日水果/蔬菜摄入量为7.5份。夏洛特市和华盛顿特区之前未参与农贸市场营养计划的参与者的农贸市场使用率相似（分别为32.4%和40%）；华盛顿特区之前参与过农贸市场营养计划的参与者的农贸市场使用率更高（为61%）（P = 0.006）。之前参与农贸市场营养计划（比值比[OR]：3.30；95%置信区间[CI]：1.57至6.93）、之前兑换农贸市场营养计划代金券（OR：4.96；CI：2.15至11.45）以及较高的水果/蔬菜摄入量（OR：2.59；CI：1.31至5.12）与农贸市场使用相关。在控制城市因素后，之前兑换过农贸市场营养计划代金券的妇女更有可能使用农贸市场（OR：6.90；CI：1.54至31.00）。常见的障碍是家附近缺乏农贸市场以及缺乏前往农贸市场的交通工具。收到并兑换了农贸市场营养计划代金券的妇女在农贸市场购买水果/蔬菜的可能性要大得多。有必要开展未来研究，以探索城乡地区WIC参与者使用农贸市场的障碍和激励因素。
