Study Overview
Brief Summary
In 1986, The Pioneer Valley in Western Massachusetts was home to one of the first two community supported agriculture (CSA) businesses in the USA. In 2014, there were 6,200 CSAs across the states, and today, in the Pioneer Valley alone, there are sixty CSAs. As with many parts of the United States, there are too many CSAs competing for the same pool of middle and upper-class customers. In his research at the University of Massachusetts in 2014, Mark Paul stated CSA farms are trapped in a lose-lose conundrum in which the farmers are not making enough money for a living wage, while simultaneously CSA shares are too expensive for many community members. The central challenge facing the CSA model moving forward is to provide fair compensation to farmers and farm workers, while making shares available at prices that can attract more members of the community. "(Im)Proving the CSA Model" proposes to increase consumption of and access to local products AND to develop new market opportunities for farms by opening the CSA membership base nationwide to low-income consumers and more price conscious middle class consumers. The investigators will do this by researching and documenting the health benefits of belonging to a CSA program. The investigators expect the resulting data to justify insurance-provided cash "wellness" benefits for CSA participation, much like those currently provided for gym membership. A wellness benefit will provide the financial incentive necessary to open CSA programs to lower- and middle-income consumers.
The two-year research study intends to demonstrate that enrolling community health center patients in a Community Supported Agriculture (CSA) program is feasible and leads to dietary improvements that would be expected to offer clinical benefits in larger scale studies over longer timeframes. To maximize the knowledge gained from participation in this study, the investigators will measure several self-reported, laboratory, and clinical outcomes, but the primary purpose of this study is to provide pilot data for the model.
To test this the investigators will implement a randomized controlled clinical trial design, with individual-level randomization of 120 participants, assigned in 1:1 ratio to receipt of a CSA membership (goal: 60 participants) or enhanced usual care (goal: 60 participants).
