Abstract

Abstract 

Type 2 diabetes disproportionately affects Hispanic adults and may be more difficult to manage among uninsured and underserved populations experiencing barriers to healthcare, nutrition education, and culturally appropriate resources. The purpose of this Doctor of Nursing Practice quality improvement project was to implement and evaluate a brief, culturally tailored nutrition education intervention for Hispanic adults with elevated A1C receiving care at The Agape Clinic in Dallas, Texas. A quantitative, quasi-experimental, within-subject design was used. The intervention provided bilingual, low-literacy education focused on A1C, portion control, added sugars, and culturally familiar foods. Thirty-eight participants enrolled in the project, and 11 had both baseline and post-intervention A1C values available for final analysis. Mean A1C increased from 7.45% at baseline to 7.60% post-intervention. The difference was not statistically significant, t(10) = 1.35, p = .208. A Wilcoxon signed-rank test also demonstrated no statistically significant difference (p = .282). A1C decreased in three participants, increased in six, and remained unchanged in two. Although the intervention did not result in a statistically significant improvement in A1C, the project demonstrated that brief, culturally tailored nutrition education could be incorporated into routine care within a resource-limited community clinic without interfering with normal clinic flow. Findings support nutrition education as one component of comprehensive diabetes management and highlight the need for continued reinforcement, structured follow-up, and consideration of additional factors influencing glycemic control.
