About
This two-arm, parallel randomized trial study will assess the efficacy of a 6-month (26 weeks) community-based program in reducing kidney injury (as Urine Albumin to Creatinine ratio, uACR), cardiovascular risk (as Hemoglobin A1C and blood pressure), mental health (as PHQ-8) and diet quality (as fruits and vegetables intake and Healthy Eating Index) in community-dwelling, low-income adults diagnosed with early chronic kidney disease (stages 2 or 3 and not on kidney replacement therapies) compared to educational materials and usual care alone.
Full description
This study tests a community-based program aimed at supporting adults with early-stage chronic kidney disease to change their eating habits to reduce the likelihood of kidney injury progression.
The program components were design to reduce barriers to a) eating healthier, kidney-friendly foods through the direct provision of fruits and vegetables, grocery store e-gift cards, kidney-friendly recipes, and food preparation tips; b) learning about kidney disease and the role of healthy eating in slowing its progression through educational materials; and c) social connection through empathetic relational phone calls and SMS texts from a dedicated "Health Partner".
Over a period of 6 months (26 weeks), participants randomized to the intervention arm will receive:
- kidney-friendly produce (fruits and vegetables) delivered at their preferred location
- recipes and tips on food preparation tailored to the produce
- grocery store electronic gift cards
- educational materials on CKD and disease management
- personalized practical and emotional support through a dedicated Health Partner
Researchers will see if participation in the program (intervention) reduces markers of kidney injury (Albumin:Creatinin ratio) and cardiovascular disease risk and improves diet (particularly fruits and vegetables intake) and mental health when compared to usual care (control).
