Background: Chronic kidney disease is a progressive condition marked by structural and functional changes in the kidneys, often resulting from various underlying health issues. Elderly with chronic kidney diseases, especially those on maintenance dialysis, are at a high risk of protein-energy wasting. Therefore, it is crucial to provide dietary education to help manage their nutritional status and overall health. Aim:  evaluate effect of nutrition education program on nutritional status of geriatric patients with chronic kidney diseases. Setting: This study was carried out at outpatient nephrology clinic at New Mansoura General Hospital. Subjects: The study subjects were selected using the purposive sampling technique which included 60 elderly patients diagnosed with chronic kidney disease. Tools: Two tools were used in this study; Structured Interview Sheet, Mini Nutritional Assessment short-form. Results: There is a statistically significant difference P<0.001 in the nutritional status at post 1 and post 2 after program implementation. About 41.6% of the studied elderly were obese before the program while this percentage decreased to 31.6% post 2 after program implementation. The percentage of the studied elderly who have a normal body weight increased from 18.3% to 36.6% after the program. Conclusion: a statistically significant difference P<0.001 in the nutritional status which mean improvement in the nutritional status at post 1 and post 2 after program implementation. The dietary intervention program decreased the risk of chronic renal disease and improved nutritional status. Recommendation: Provide continuous support and follow-up for elderly chronic kidney disease patients post-education programs to monitor their progress and adherence to dietary recommendations.
