Partner organizations selected 33 community sites that reached individuals with lower-income and limited access to healthy food. Eligible study participants were age 18+, the primary household shopper, and lived near\/frequented the community site; 699 participants were enrolled across all communities. Sites were randomized in pairs to receive the VV intervention (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200917 sites) or a planning condition (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200916 sites) for one year.\n                    <\/jats:p>\n                    <jats:p>Outcomes were change in food security, F&amp;V consumption measured by food frequency and 24-hour recalls, dermal carotenoid levels and nutrition-related psychosocial measures. Generalized linear mixed models were used to examine the effect of the intervention while adjusting for clustering within sites and baseline values.

Study implementation, recruitment, and data collection were significantly altered by the COVID-19 pandemic. While the magnitude of changes in F&amp;V intake at post-COVID sites was similar to previous research, we did not find statistically significant differences between groups for F&amp;V intake. Analyses also indicated that VV users improved their food security.
