Direct-to-consumer marketing efforts, such as community-supported agriculture (CSA), have been proposed as a solution for disparities in fruit and vegetable consumption. Evaluations of such efforts have been limited. The objective of this study was to test the feasibility of a CSA intervention to increase household inventory of fruits and vegetables and fruit and vegetable consumption of residents of an underresourced community.
For this randomized, controlled feasibility study, we recruited 50 low-income women with children. Intervention (n=25) participants were offered 5 educational sessions and a box of fresh produce for 16 weeks; control participants were not offered the sessions nor were they included in the produce delivery. We collected data on participants' home inventory of fruits and vegetables and on their consumption of fruits and vegetables at baseline (May 2012) and postintervention (August and September 2012).
Of 55 potential participants, 50 were enrolled and 44 were reached for follow-up. We observed a significant increase in the number of foods in the household inventory of fruits and vegetables in the intervention group compared with the control group. The intervention group reported greater increases in fruit and vegetable consumption; however, these did not reach significance. Intervention participants picked up produce 9.2 (standard deviation=4.58) of 16 weeks; challenges included transportation and work schedules. Most participants (20 of 21) expressed interest in continued participation; all stated a willingness to pay $10 per week, and some were willing to pay as much as $25 per week.
CSA is a feasible approach for providing fresh fruits and vegetables to an underresourced community. Future studies should evaluate the impact of such a program in a larger sample and should take additional steps to facilitate participation.
直接面向消费者的营销活动,如社区支持农业(CSA),已被提议作为解决水果和蔬菜消费差异的一种方法。此类努力的评估有限。本研究的目的是测试 CSA 干预措施增加贫困社区家庭水果和蔬菜库存以及居民水果和蔬菜消费的可行性。
这项随机对照可行性研究招募了 50 名有孩子的低收入妇女。干预(n=25)参与者接受了 5 次教育课程和 16 周的新鲜农产品供应;对照组没有提供课程,也没有包括在农产品供应中。我们收集了参与者家庭水果和蔬菜库存以及他们在基线(2012 年 5 月)和干预后(2012 年 8 月和 9 月)水果和蔬菜消费的数据。
在 55 名潜在参与者中,有 50 名参加了研究,其中 44 名接受了随访。我们观察到干预组家庭水果和蔬菜库存中的食物数量明显增加,而对照组则没有。干预组报告水果和蔬菜消费有较大增加;然而,这些并没有达到显著水平。干预参与者在 16 周内取走了 9.2(标准差=4.58)的农产品;面临的挑战包括交通和工作安排。大多数参与者(21 名中的 20 名)表示有兴趣继续参与;所有人都表示愿意每周支付 10 美元,有些甚至愿意每周支付 25 美元。
CSA 是向资源匮乏社区提供新鲜水果和蔬菜的可行方法。未来的研究应该在更大的样本中评估该计划的影响,并应采取额外措施促进参与。
