About

Food insecurity predisposes to poor diet, thereby increasing risk for diet-sensitive chronic disease. This trial is to evaluate the impact of a model of weekly home-delivery of locally-grown vegetables along with selected whole grains on diet among low-income children living in a household with food insecurity. The investigators plan to enroll children (10-15 years) who will participate along with their parent/caregiver. Intervention will consist of 12 weeks of weekly delivered food plus recipes and text-messaged links to cooking instruction. Dyads will be randomized (2:1) to either immediate intervention or a wait-list control group, and diet and diet-related behaviors will be assessed in-person as well as over the telephone.

Full description

Children and their families who are seen at the investigators primary care clinic will be screened for eligibility by the research team study staff, and caregiver/parents will be asked a short 2-item screener about access to food. This screener has been called the "Hunger Vital Sign". When a screen for household food security is positive, caregivers are invited to participate in this study along with their child, as a dyad.

This is a randomized clinical trial. The first activity consists of an in-person visit where child and caregiver answer survey questions related to diet (specifically regarding vegetable and whole grain purchase and consumption). Anthropometrics are measured. The child has a 24-hour diet recall that is conducted in person at this visit, and then two more times in the intervening time (approximately 2 weeks). They are randomized (2:1) at this visit to either receive 12 weeks of deliveries immediately (starting in approximately 2 weeks) or after a delay of 3 months, when they serve as the delayed-intervention control group.

Immediate intervention group receives a weekly delivery of vegetables and whole grains as well as 1-2 weekly text messages that contain education such as links to cooking tips and videos.

After 3 months, both immediate intervention and the delayed intervention groups return for a second in-person visit, and complete all of the visit activities. Delayed intervention group starts their deliveries at this point.

After 3 months, the delayed intervention group returns for a third in-person visit, though the immediate intervention participants complete their follow-up survey questions over the telephone, only.

This home delivery model, done in coordination with a community-supported has been successfully-piloted in a population of low-income dyads with a child having prediabetes.

• dyad must reside in Oakland, CA (delivery range for farm)

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: None (Open label)

---

68 participants in 2 patient groups

Immediate intervention

Experimental group

Description:

If randomized to this group, household of child and participating caregiver receives 12 weekly deliveries of vegetables plus added whole grains, along with text messages containing links to cooking instruction videos

Treatment:

Behavioral: Food as Medicine Delivery

Wait list control (delayed intervention)

Other group

Description:

If randomized to this group, participants do not get any intervention activities for the first 12 weeks, and their outcome data at V2 contribute as controls. For ethical reasons, this low-income population ultimately gets the intervention (food)later, and data after they receive the intervention contributes to follow-up data only.

Treatment:

Behavioral: Food as Medicine Delivery
