Objectives: As Chronic Kidney Disease (CKD) progresses, inadequate nutrient consumption may lead to weight loss, malnutrition, and lower quality of life. Therefore, this study aims to investigate evaluate food and nutrient intake through the Diet Quality Index-International (DQI-I) in patients with chronic kidney disease not yet treated with dialysis. Methods: Patients were recruited from Yongin Severance Hospital and patients with CKD stage 3 or higher. To investigate the patients' food intake and nutrient intake status, 24-hour recall method and the Korean Mediterranean Diet Adherence Screener (K-MEDAS) were used, and the DQI-I was used as a quality evaluation tool. Results: Among 155 patients, 92 (59.4%) were male and 63 (40.6%) were female and the mean age was 70.8±11.3 years. The mean treatment period was 30.2±35.2 months, most of the patients were CKD stage 3(77.4%). The mean daily energy intake 21.5±6.9 kcal/kg, protein intake 0.83±0.36 g/kg, and sodium intake was 2604.1±1339.9 mg. The mean DQI-I total score was (65.9±9.1 vs. 64.8±8.9) and there was no significant difference between males and females. The scores of cholesterol, sodium, and empty calorie foods consumption were significantly higher in the female group than in the male group (p<0.05). The mean K-MEDAS total score was (5.6±1.8 vs. 5.8±1.7) and there was no significant difference between males and females. Among the K-MEDAS items, the lowest score (less than 0.5) was Wine> Total olive oil and perilla oil > Fish and seafood> Nuts, Pulses> Preference for white over red meat> vegetables. Conclusions: Compared with the Kidney Disease Improving Global Outcomes (KDIGO) guidelines, energy intake was low, while protein and sodium intake were within recommendation. In addition, it was found that the intake of potassium did not significantly exceed the appropriate range, and dietary fiber was sufficiently consumed. Further investigation regarding relationship between diet and lab profile still remains.
