Pilot Subsidized and Culturally-adapted Community Supported Agriculture (CSA) Program

A Pilot Study of a Subsidized and Culturally-adapted Community Supported Agriculture (CSA) Program

This study aims to apply community-engaged methods to refine and implement a culturally adapted systems-level program for improving diet in low income, Chinese American immigrants. Guided by the regular partner engagement, The researchers have organically developed a systems-level program to bring a subsidized community-supported agriculture (CSA) model to the community in a way that is aligned with cultural values, and that includes culturally appropriate produce and nutrition education.

This is a single-site proof of concept pilot program that will be evaluated using a pre-post-design.

Intervention / Treatment

Experimental: Study Group; Low-income Chinese American immigrant families with a focus on adults 18+ years in Brooklyn will participate in a culturally adapted systems -level program for improving diet.

Behavioral: CSA model; Community-supported agriculture (CSA) involves a community of individuals who support a farm and in return receive distributions of the farm's produce throughout the growing season. Culturally appropriate produce will be provided in subsidized weekly boxes for 20 weeks to community members at Brooklyn Grange Farm in Sunset Park at a fee of $5, which was determined to be acceptable by community members. Participants that receive SNAP benefits can use their EBT card to cover their $5. Education will be offered in the form of nutrition education, cooking tutorials, and farming information provided by staff at Brooklyn Grange.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Diet Quality - Frequency	Diet quality will be self-reported via a follow-up survey. Frequency (how often vegetables were consumed in the past month) is reported on a Likert scale: 1 = once a month, 2 = two or three times a month, 3 = once a week, 4 = more than once a week.	Baseline, Week 20
Change in Diet Quality - Quantity of Serving	Diet quality will be self-reported via a follow-up survey. Quantity of Serving (how much is consumed at a time) is reported on a Likert Scale: 1 = less than ¼ cup, 2 = ¼ to ½ cup, and 3 = more than ½ cup.	Baseline, Week 20
Change in Number of Different Vegetables Consumed	Diet quality will be self-reported via a follow-up survey. The participant is presented with a list of 29 different vegetables - he/she is asked to select all of the vegetables in the list that was consumed in the past month.	Baseline, Week 20

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Food Insecurity Score	Food insecurity will be self-reported via a follow-up survey. The survey consists of 2 questions, reported on a Likert scale: 1 = often true, 2 = sometimes true, 3 = never true. The total range of score is 2-6; the higher the score, the lesser the insecurity.	Baseline, Week 20
Change in Social Cohesion Score	Social cohesion will be self-reported via a follow-up survey. The survey consists of 3 questions, reported on a Likert scale: 0 = often, 1 = some of the time, 2 = hardly ever, 3 = never. The total score range is 0-9; the higher the score, the greater the sense of social cohesion.	Baseline, Week 20
