The Impact of an Education Intervention to Improve Blood Pressure Control among Black Non-Hispanic Patients and Hispanic Patients with Chronic Kidney Disease

Nephrol Nurs J. 2022 Jul-Aug;49(4):351-358.

Abstract

This project examined the effect of an educational intervention on blood pressure control among minority patients with chronic kidney disease (CKD). Adherence to a low-sodium diet is crucial for blood pressure control. It is also vital to assess food insecurity to improve diet adherence, especially among high-risk underrepresented populations. Participants were recruited from a public hospital renal clinic. Knowledge and food access was assessed using CKD and food insecurity questionnaires. Food frequency and 24-hour 3-day food diaries were completed and analyzed. Eighteen patients were enrolled (Black, non-Hispanic = 66.6%, Hispanic = 27.7%, uninsured = 33.3%, and Medicaid recipients = 27.7%). Eighty-nine percent of participants screened positive for food insecurity and received vouchers for healthy food from a food depository. Paired t tests showed statistically significant increase in knowledge (p < 0.00) and self-efficacy, and systolic blood pressure improved post-intervention. This study suggests that Black non-Hispanic and Hispanic patients with CKD have limited access to healthy food and consume higher sodium. Patient education, screening for food insecurity, and access to a food depository enhanced adherence to low sodium diet and improved blood pressure control.
