Reducing Chronic Kidney Disease Burden in an Underserved Population

November 25, 2020 updated by: Baylor Research Institute

A Prospective, Randomized Two Group Study to Evaluate the Feasibility and Initial Efficacy of a Community-engaged Screening, Identification, and F&V Intervention to Improve F&V Intake and CKD Outcomes in 140 AA Adults

To evaluate a scalable population health strategy to 1) screen, 2) identify, and 3) intervene with individuals at high risk of CKD progression to ESRD that could be implemented in other high risk communities and health care systems. This novel study will evaluate the feasibility and preliminary efficacy of providing F&V to individuals identified at high risk study for CKD and ESRD through community health screenings. Further, it will evaluate whether providing education as to how to prepare F&V for consumption, the latter being done for all F&V recipients in PI's preliminary published studies but its efficacy was not specifically tested, increases F&V intake and thereby reduces CKD progression risk as well as related clinical outcomes.

Detailed Description

"Fruits and Veggies for Health" is a prospective, randomized two group study to evaluate a community-engaged screening, identification, and F&V intervention to improve CKD outcomes in 140 AA adults (greater than 18 years). Participants will be randomized to a 1) F&V only (F&V Only), or 2) F&V plus a nutrition/cooking program (F&V + Cook).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Fruits and Vegetables Only
This group will receive a prescribed amount of free fruits and vegetables (F & V) for 6 weeks through pick-up at a farm stand, or direct delivery. After 6 weekly pick-up/deliveries, participants will be provided vouchers and reminders to obtain F&V at farm stands for an additional 18 weeks with minimal contact
Other: Fruits and Vegetables
Fruits and vegetables delivery, once/week for 24 weeks
Experimental: Fruits and Vegetables and Cook
In addition to the prescribed amount of free F&V, participants will receive 6 weekly, group nutrition and cooking education classes based on "The Happy Kitchen" curriculum. Participants will also receive free ingredients to complete the recipe from each weekly session at home.
Other: Fruits and Vegetables
Fruits and vegetables delivery, once/week for 24 weeks
Other: Cooking
Nutrition education and cooking instruction class, one class/week for 6 weeks
