Veggie Van Toolkit

Overview

The Veggie Van (VV) Toolkit is a policy, systems, and environmental change intervention designed to:

Increase access to healthy, affordable fruits and vegetables in lower income and/or food insecure communities
Help the target population improve their diets through skill building
Address the interplay between the physical food environment, individual perceptions of that environment, and self-efficacy
Address multiple dimensions of access to fresh produce for lower-income and under-served communities, including availability, affordability, accessibility (geographic and financial), and accommodation
Improve self-efficacy for finding, purchasing, and preparing fruits and vegetables or other healthy foods via cooking and nutrition education interventions

VV achieves these goals via mobile farmers markets that present cooking demonstrations, recipes, taste tests, and nutrition education to help customers better use the produce they receive. VV mobile markets also accept SNAP benefits, electronic benefits (EBT), and other relevant local food incentive and benefit programs, as well as employ a bundling model in addition to a la carte purchasing. The bundling model allows the VV mobile markets to sell more items at a lower cost and expose participants to a greater variety of fruits and vegetables. Markets operate a minimum of 10 months out of the year and typically source produce locally or regionally.

Intervention Target Behavior: Healthy Eating, Food Insecurity/Food Assistance

SNAP-Ed Strategies: PSE Change

Intervention Reach and Adoption

VV targets lower-income individuals and families receiving SNAP and other nutrition or social programs at community organizations, such as health clinics, lower-income housing communities, and recreation centers. The design of the VV intervention is such that the organization's community ties are expanded, enhanced, and/or established through partner organizations already directly serving lower-income populations. This is essential because lower-income communities and communities of color often have less geographic access to stores selling fresh fruits and vegetables, which can influence perceptions of convenience of purchasing and preparing fresh fruits and vegetables. Veggie Van is designed to address these perceptions of the food environment by increasing access to fresh fruits and vegetables both geographically and socially. The pilot evaluation of VV reached 72 participants at three sites: a lower-income housing community, a community college, and a health department. The cluster-randomized controlled trial reached 201 participants at 12 sites.

Settings: Farmers markets, Pre-K & Childcare, Community-wide, Faith-based centers, Healthcare, Tribal Reservations, Schools, USDA program sites

Age/Population Group: Preschool, Elementary School, Middle School, High School, Pregnant/Breastfeeding, Parents/Caregivers, Adults, Older Adults

Race: All

Ethnicity: No special focus.

Intervention Components

The VV toolkit includes resources to plan and implement a mobile market serving lower-income communities. These intervention components provide the plans and documents necessary to start a mobile market from the ground up.

Core components include:

Resources to assess community interest in a mobile market
Guidelines for identifying stakeholders and community partners
Resources to aid in developing a mobile market model
Strategies to identify and work with market host sites
Logistics for launching the program
Educational materials
- Produce information in multiple formats to provide to participants
- Ideas for cooking demonstrations
- Ideas for taste tests

Components can be customized according to the specific needs of implementing organizations, as well as their financial and social resources for starting the program.

Evidence Summary

A summary of the VV outcomes can be found on the outcomes page

Outcomes include:

People using VV found it easier to make a veggie dish with what they had on hand
People in communities with VV were eating 3.6 cups per day of fruits and veggies while people in communities without VV were only eating 2.8 cups per day

The VV received feedback from study participants via the Mobile Market Survey, focus groups with participants, and the Green Chart Evaluation Follow-up Survey. Based on feedback, two additional dimensions were added to the VV program to help ensure that research participants would receive at least a minimal dose of the intervention: dissemination of a VV newsletter and a voucher for a free bundle of produce.

Lessons learned from the pilot and subsequent four VV sites operated in North Carolina include:

Specific barriers to serving seniors
Mixed perceptions of the bundling model for selling produce
Participant perceptions of produce quality connected to their status as members of the target community

Evidence Base: Research-tested

Evaluation Indicators

Based on the SNAP-Ed Evaluation Framework, the following outcome indicators can be used to evaluate intervention progress and success.

	Readiness and Capacity - Short Term (ST)	Changes - Medium Term (MT)	Effectiveness and Maintenance - Long Term (LT)	Population Results (R)
Individual	ST1	MT1
Environmental Settings	ST7
Sectors of Influence

ST1: Healthy Eating
- The number of participants who set goals or intent to eat fruit
- The number of participants who set goals or intent to eat vegetables
ST7: Organizational Partnerships
- In 2012-2015, a total of 53 community organizations were approached for recruitment, and ultimately, 12 sites were enrolled (Tripicchio et al. 2017)
MT1: Healthy Eating
- MT1l: Cups of fruit consumed per day
- cups of vegetables consumed per day
  - In the pilot phase (2011-2013), individuals who reported shopping at Veggie Van frequently (n = 32) increased their F&V consumption by 0.41 servings/day compared with a decrease of −1.19 for those who rarely/never used Veggie Van (n = 27), a total difference of 1.6 servings/day (P = 0.01). RCT results from 2013-2016 (published 2019), indicate a mean reported F/V intake of 3.4 cups/day.
