Clinical Effectiveness of MyNutriKidney®

General Objective: To evaluate the clinical effectiveness of supplementing standard care with the MyNutriKidney® mobile application compared to standard care alone in improving dietary adherence and nutrition literacy among patients with Chronic Kidney Disease (CKD) stages 3-5 in Malaysia over a 6-month period. Specific Objectives: 1. To compare the change in Dietary Adherence (DA), assessed by the CKD Diet Score (derived from 3x 24-hour dietary recalls), from baseline to 6 months between the MyNutriKidney® intervention group and the standard care control group. (Co-primary objective) 2. To compare the change in Nutrition Literacy (NL), assessed by the Nutrition Literacy Scale (NLS) score, from baseline to 6 months between the intervention and control groups. (Co-primary objective) 3. To compare the changes in secondary outcomes from baseline to 6 months between the two groups, including: 3.1. Dietary Knowledge, assessed by the Dietary Knowledge Questionnaire (DKQ) score. 3.2. Kidney Function, assessed by the estimated Glomerular Filtration Rate (eGFR). 3.3. Serum Electrolyte Levels (Potassium, Phosphorus, Sodium, Calcium). 4. To evaluate app engagement metrics (e.g., meal logging frequency, time spent on educational resources, challenge completion) among participants in the MyNutriKidney® intervention group over the 6-month period. (Exploratory objective) 5. To assess participant satisfaction and usability of the MyNutriKidney® app using the Malay version of the mHealth Application Usability Questionnaire (M-MAUQ) at 6 months among participants in the intervention group.
