本文研究了低收入家庭的水果和蔬菜摄入量，这些家庭参加了一项成本补偿(CO)或50%补贴的社区支持农业(CSA)计划。CSA的客户预先向农场支付收获分成，并在整个生长季节每周收到农产品。在一个夏季的CO-CSA中，一组2-12岁的成年人和儿童在网上进行了两次调查：2015年8月(n=41)和2016年2月(n=23)。FVI是由国家癌症研究所(NCI)的水果和蔬菜筛选器(FVS)和当地种植的水果和蔬菜库存来测量的。使用非参数检验和配对t检验(p<；0.05)对FVI相对于美国(US)的建议和平均值以及跨季节进行了检验。CO-CSA中的成年人和儿童的FVI都高于美国平均水平，而且更多地符合蔬菜的推荐标准。一些夏季的水果和蔬菜更常在当地的季节食用。作为改善低收入家庭成人和儿童蔬菜消费的途径，CO-CSA模式值得进一步研究。然而，不能推断CO-CSA参与和FVI之间的因果关系，因为CO-CSA参与者可能是FVI的积极偏离者。目前正在进行一项多状态随机对照试验，以评估CO-CSA对FVI和相关结果的影响。
This paper examines fruit and vegetable intake (FVI) in low-income households that participated in a cost-offset (CO), or 50% subsidized, community-supported agriculture (CSA) program. CSA customers paid farms upfront for a share of the harvest, and received produce weekly throughout the growing season. A cohort of adults and children 2–12 y in a summer CO-CSA were surveyed online twice: August 2015 (n = 41) and February 2016 (n = 23). FVI was measured by the National Cancer Institute’s (NCI) Fruit and Vegetable Screener (FVS) and an inventory of locally grown fruits and vegetables. FVI relative to United States (US) recommendations and averages, and across seasons, were tested with non-parametric tests and paired t-tests (p < 0.05). Both adults and children in the CO-CSA had higher FVI than the US averages, and more often met recommendations for vegetables. Some summer fruits and vegetables were more often eaten when locally in-season. The CO-CSA model warrants further examination as an avenue for improving vegetable consumption among adults and children in low-income households. However, causality between CO-CSA participation and FVI cannot be inferred, as CO-CSA participants may be positive deviants with respect to FVI. A multi-state randomized controlled trial is currently underway to evaluate impacts of CO-CSAs on FVI and related outcomes.
