There is a need to improve geographical and financial access to healthy foods for limited resource populations in rural areas. Community Supported Agriculture (CSA) programs can improve access to healthy foods in rural and limited-resource populations. However, research is needed to discern the most appealing conditions for a CSA (e.g. price, frequency, food quantity) among rural, low-income customers. The goal of this study was to understand low-income consumers' preferences related to participation in a CSA program, considering price, frequency, food quantity and accessibility (e.g. distance) conditions. A modified exploratory choice experiment exercise was embedded within in-depth interviews to examine willingness to participate in CSA under a variety of conditions among 42 low-income adults with at least one child in the household in North Carolina, New York, Vermont and Washington. Willingness to participate in a CSA under each condition was summed and compared across conditions. Results were stratified by race, number of children and household members and McNemar's test and Student's t-test were used to examine differences in willingness between conditions. Salient quotes were extracted to support themes related to each condition. Our analysis suggests that the ideal CSA would be a full-sized share of eight to nine items of mixed variety, distributed every other week, priced at less than US$15, no more than 10 min further than the supermarket (SM) from their home and preferably less expensive but no more than 20% more expensive than SM prices. CSAs interested in reaching rural low-income populations may benefit from considering these consumer-level preferences.

一项改进的选择实验，以检查低收入父母参与社区支持农业 (CSA) 计划的意愿

有必要改善农村地区资源有限的人口获得健康食品的地理和财政机会。社区支持农业 (CSA) 计划可以改善农村和资源有限人口获得健康食品的机会。然而，需要进行研究，以确定农村低收入客户中最吸引 CSA 的条件（例如价格、频率、食物数量）。本研究的目的是了解低收入消费者对参与 CSA 计划的偏好，同时考虑价格、频率、食物数量和可及性（例如距离）条件。一项改进的探索性选择实验练习嵌入了深度访谈中，以检查北卡罗来纳州、纽约州、佛蒙特州和华盛顿州的 42 名家庭中至少有一个孩子的低收入成年人在各种条件下参与 CSA 的意愿。对每种条件下参与 CSA 的意愿进行汇总并在不同条件下进行比较。结果按种族、儿童和家庭成员数量以及 McNemar 测试和学生测试进行分层吨-测试用于检查条件之间的意愿差异。提取了突出的引语以支持与每个条件相关的主题。我们的分析表明，理想的 CSA 应该是 8 到 9 种混合品种的全尺寸份额，每隔一周分发一次，价格低于 15 美元，距离他们家的超市 (SM) 不超过 10 分钟最好比 SM 价格便宜，但不超过 20%。有兴趣接触农村低收入人口的 CSA 可能会从考虑这些消费者层面的偏好中受益。
