• Conditions: Fruit and Vegetable Consumption

• Registration Number: NCT06455215
• Lead Sponsor: University of Arkansas

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 18-85 living in low resource and African American communities. Gardens will be randomized to the intervention (n=3 gardens) or control group (delayed intervention, n=3 gardens). Participants will be assigned to one of six 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 18-85 living in low resource and African American communities. Participants will be assigned to one of six 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. Three 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.

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: PARALLEL

Primary Outcome Measures

Name	Time	Method
Fruit and vegetable intake	From baseline to 8 weeks (end of intervention) and 6-months post intervention	We will use the five factor screener that is used to approximate intake of fruit juices, fruit, green leafy vegetables, other vegetables, tomato-based sauces, potatoes, and beans

Secondary Outcome Measures

Name	Time	Method
Access to healthy foods	From baseline to 8 weeks (end of intervention) and 6-months post intervention	We will use the the Perceived Availability of the Healthy Food Scale. Participants will be asked to think of the neighborhood area (1 mile radius) and the extent to which they feel that the foods are of high quality, available, and are low fat.
