Accepts healthy volunteers: yes
Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: Randomization will occur at the garden level. Four gardens will be randomized to the intervention and three gardens to the control group. The participants assigned to the four gardens in the intervention group will receive an 8-week intervention that includes 1) educational materials, 2) healthy cooking demonstrations, 3) food and transportation support and 4) garden social activities. The control garden group will not receive an intervention during this time period which allows us to evaluate differences in the primary and secondary outcomes in the intervention and control groups at 8 weeks and 6 months.

The control group will receive the delayed 8-week intervention one month after the intervention group.
Primary purpose: PREVENTION

Brief summary: The goals of this community-based clinical trial are to examine the association between community garden participation and 1) fruit and vegetable intake (primary outcome) and 2) access to healthy food (secondary outcome) among adults aged 18-95 living in low resource and African American communities. Gardens will be randomized to the intervention (n=4 gardens) or control group (delayed intervention, n=3 gardens). Participants will be assigned to one of seven community gardens to receive an 8-week intervention. During the intervention, participants will be asked to volunteer in the garden, participate in garden social activities, participate in healthy cooking demonstrations and educational sessions. Participants will receive educational materials as well. To assess the effects of the intervention, participants will receive a baseline, 8-week, and 6-month survey. Outcome measures will be compared between the intervention and control groups.

Detailed description: Food insecurity is a major cause of chronic diseases and is highest in the nation in Arkansas. Evidence shows that community gardens and healthy cooking demonstration can reduce food insecurity by 1) increasing access to healthy foods and 2) promoting healthy food consumption. Community garden participation is one factor that can influence healthy food consumption such as fruit and vegetable intake. The goals of this community-based clinical trial are to examine the association between community garden participation and 1) fruit and vegetable intake (primary outcome) and 2) access to healthy food (secondary outcome) among adults aged 18-95 living in low resource and African American communities. Participants will be assigned to one of seven community gardens to receive an 8-week intervention. During the intervention participants will be asked to volunteer in the garden, participate in garden social activities, participate in healthy cooking demonstrations and educational sessions. Participants will receive educational materials as well. Four of the gardens will be randomized to the intervention group and three to the delayed intervention group. To assess the effects of the intervention, participants will receive a baseline, 8-week, and 6-month survey. Other measures that we will examine include food security; sociodemographics; physical activity; life satisfaction; perceived stress; neighborhood collective efficacy; self-efficacy; individual level social determinants of health; community engagement; and knowledge, attitudes, and satisfaction related to gardening and cooking.
