Hyperkalemia and hyperphosphatemia are common complications in non–dialysis-dependent chronic kidney disease (ND-CKD). Given the limited therapeutic options, dietary intervention remains the cornerstone of prevention. This study evaluated the impact of a nutritional education (NE) program on patients’ knowledge, attitudes, and behaviors (KAB) toward low-potassium and low-phosphate diets, and its influence on electrolyte abnormalities in ND-CKD patients.
A quasi-experimental study was conducted at our nephrology clinic between January and June 2025. Data collected included sociodemographic characteristics, clinical and laboratory profiles, and anthropometric measurements (including bioimpedance spectroscopy parameters). A self-developed 24-item questionnaire was used to assess participants’ KAB scores regarding potassium- and phosphate-rich foods. Participants were randomly assigned to Group 1, who received NE via brochures only, or Group 2, who received brochures plus a single dietary counseling session led by a registered dietitian. Changes in KAB scores and clinical parameters were evaluated after a 30-day follow-up at the subsequent outpatient visit.
A total of 127 participants (mean age 63.7±12.5 years; 55.9% male) were enrolled. Baseline demographic, clinical, and anthropometric characteristics were comparable between groups (Group 1 = 50; Group 2 = 77). Most patients had stage 4 CKD (45.7%), senior high school education (43.3%), and caregiver dependence (60.6%). The most common comorbidities were type 2 diabetes mellitus (72.4%) and hypertension (49.6%). The incidences of hyperkalemia and hyperphosphatemia were 17.3% and 14.2%, respectively. A KAB cut-off score of 56.4, derived from receiver operating curve (ROC) analysis, predicted a higher risk of electrolyte disturbances. The mean baseline KAB score was 55.8±11.7, with 48.8% of participants scoring below this threshold. After 30 days, both groups showed statistically significant improvements in all KAB score components (p <0.05). Post-intervention, no statistically significant difference was observed between groups in the reduction of hyper-K and hyper-P; however, Group 2 showed a decline in the absolute proportion of hyper-K (23.1 to 13.5%), while Group 1 demonstrated an increase in both hyper-K (11.1 to 22.2%) and hyper-P (8.3 to 11.1%).
Nutritional education—whether brochure-based or supplemented with direct counseling—significantly improved KAB scores among ND-CKD patients. Incorporating individualized dietary counseling may further help prevent hyperkalemia and hyperphosphatemia, underscoring the clinical relevance of structured NE programs in CKD management. The persistent or rising rate of hyperphosphatemia suggests that its control may depend on additional factors beyond dietary education alone.
