Low-income individuals’ perceptions about fruit and vegetable access programs: A qualitative study (2015)Objective—To examine how fruit and vegetable (F&V) programs address barriers to F&V access and consumption as perceived by low-income individuals.
Design—From 2011–2012 thirteen focus groups were used to better understand low-income individuals’ perceptions about F&V programs. Setting—Five North Carolina counties at community-serving organizations. Participants—Low-income participants ages 18 or older were included in the study. A majority were African American females with a high school education or less and received government assistance. Phenomenon of Interest—Low-income individuals’ perceptions about how F&V access programs can reduce barriers and increase consumption. Analysis—A socioecological framework guided data analysis, and 2 trained researchers coded transcripts, identified major themes, and summarized findings. Results—A total of 105 participants discussed that mobile markets could overcome barriers such as availability, convenience, transportation, and quality/variety. Some were worried about safety in higher crime communities. Participants’ opinions about how successful food assistance programs were at overcoming cost barriers were mixed. Participants agreed that community gardens could increase access to affordable, conveniently located produce, but worried about feasibility/implementation issues. Implications for Research and Practice—Addressing access barriers through F&V programs could improve consumption. Programs have the potential to be successful if they address multiple access barriers. ![]()

Recruiting Community Partners for Veggie Van: Strategies and Lessons Learned From a Mobile Market Intervention in North Carolina, 2012–2015 |
We conducted a pilot evaluation of the Veggie Van, a mobile
produce market that brings weekly boxes of reduced-cost locally grown fruits and vegetables (F&V) to lower-income communities and offers cooking and nutrition education to customers. We conducted surveys just prior to starting Veggie Van at each of 3 sites and again at 2–3 months. F&V intake was measured with a 2-question item and a 10-item food frequency questionnaire (FFQ) in a subset of participants. At baseline, average servings/day of F&V was 4.9 (SD = 2.6, n = 60). At follow-up, 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 = .01). There were no statistically significant differences in F&V consumption between groups based on the FFQ measure. Frequent shoppers reported additional health improvements and increases in their ability to buy enough F&V. We conclude that offering weekly boxes of affordable F&V paired with education in underserved communities may improve F&V consumption for frequent program users. |
Background
Food access interventions are promising strategies for improving dietary intake, which is associated with better health. However, studies examining the relationship between food access and intake are limited to observational designs, indicating a need for more rigorous approaches. The Veggie Van (VV) program was a cluster-randomized intervention designed to address the gap between food access and intake. In this article, we aim to describe the approaches involved in recruiting community partners to participate in VV. Community Context The VV mobile market aimed to improve access to fresh fruits and vegetables by providing subsidized, high-quality, local produce in low-resource communities in North Carolina. This study describes the strategies and considerations involved in recruiting community partners and individual participants for participation in the VV program and evaluation. Methods To recruit partners, we used various strategies, including a site screener to identify potential partners, interest forms to gauge future VV use and prioritize enrollment of a high-need population, marketing materials to promote VV, site liaisons to coordinate community outreach, and a memorandum of understanding between all invested parties. Outcome A total of 53 community organizations and 725 participants were approached for recruitment. Ultimately, 12 sites and 201 participants were enrolled. Enrollment took 38 months, but our approaches helped successfully recruit a low-income, low-access population. The process took longer than anticipated, and funding constraints prevented certain strategies from being implemented. Interpretation Recruiting community partners and members for participation in a multi-level, community-based intervention was challenging. Strategies and lessons learned can inform future studies. |

A Cluster-Randomized Trial of a Mobile Produce Market Program in 12 Communities in North Carolina: Program Development, Methods, and
|
Background: Poorer diets and subsequent higher rates of chronic disease among lower-income individuals may be
partially attributed to reduced access to fresh fruits and vegetables (F&V) and other healthy foods. Mobile markets are an increasingly popular method for providing access to F&V in underserved communities, but evaluation efforts are limited. The purpose of this study was to determine the impact of Veggie Van (VV), a mobile produce market, on F&V intake in lower-income communities using a group randomized controlled trial. Methods: VV is a mobile produce market that sells reduced-cost locally grown produce and offers nutrition and cooking education. We recruited 12 sites in lower-income communities in North Carolina (USA) to host VV, randomizing them to receive VV immediately (intervention) or after the 6-month study period (delayed intervention control). Participants at each site completed baseline and follow-up surveys including F&V intake, perceived access to fresh F&V and self-efficacy for purchasing, preparing and eating F&V. We used multiple linear regression to calculate adjusted differences in outcomes while controlling for baseline values, education and clustering within site. Results: Among 142 participants who completed the follow-up, baseline F&V intake was 3.48 cups/day for control and 3.33 for intervention. At follow-up, adjusted change in F&V consumption was 0.95 cups/day greater for intervention participants (p = 0.005), but was attenuated to 0.51 cups per day (p = 0.11) after removing extreme values. VV customers increased their F&V consumption by 0.41 cups/day (n = 30) compared to a 0.25 cups/day decrease for 111 non-customers (p = 0.04). Intervention participants did not show significant improvements in perceived access to fresh F&V, but increased their self-efficacy for working more F&V into snacks (p = 0.02), making up a vegetable dish with what they had on hand (p = 0.03), and cooking vegetables in a way that is appealing to their family (p = 0.048). Conclusions: Mobile markets may help improve F&V intake in lower-income communities. |
Background Mobile markets are an increasingly popular method for providing access to fresh fruits and vegetables (F/V) in underserved communities; however, evaluation of
these programs is limited, as are descriptions of their development, study designs, and needs of the populations they serve. Objective Our aim was to describe the development and theoretical basis for Veggie Van (VV), a mobile produce market intervention, the study design for the VV evaluation, and baseline characteristics of the study population. Design The protocol and sample for a cluster-randomized controlled trial with 12 sites are described. Participants/setting Community partner organizations in the Triangle region of North Carolina that primarily served lower-income families or were located in areas that had limited access to fresh produce were recruited. Eligible individuals at each site (older than 18 years of age, self-identified as the main shoppers for their household, and expressed interest in using a mobile market) were targeted for enrollment. A total of 201 participants at 12 sites participated in the VV program and evaluation, which was implemented from November 2013 to March 2016. Main outcome measures Change in F/V intake (cups/day), derived from self-reported responses to the National Cancer Institute F/V screener, was the main outcome measure. Statistical analyses performed We performed a descriptive analysis of baseline sample characteristics. Results Mean reported F/V intake was 3.4 cups/day. Participants reported generally having some access to fresh F/V, and 57.7% agreed they could afford enough F/V to feed their family. The most frequently cited barriers were cost (55.7%) and time to prepare F/V (20.4%). Self-efficacy was lowest for buying more F/V than usual and trying new vegetables. Conclusions By addressing cost and convenience and building skills for purchasing and preparing F/V, the VV has the potential to improve F/V consumption in underserved communities. |
