초록	Objectives: To determine the prevalence of malnutrition, compare its prevalence across CKD stages, and identify factors associated with malnutrition among patients with pre-dialysis CKD stages 3–5 at Rajavithi Hospital. Methods: A cross-sectional study was conducted among patients attending the nephrology clinic at Rajavithi Hospital between January 1 and December 31, 2025. Nutritional status was assessed, and data on demographics, comorbidities, nutritional parameters, dietary intake, and laboratory findings were collected. Factors associated with malnutrition were analyzed using logistic regression analysis. Results: : A total of 312 patients with pre-dialysis CKD stages 3–5 were included. The prevalence of malnutrition was 39.3%, with 34.5% classified as moderate and 4.8% as severe malnutrition. The prevalence of malnutrition did not differ significantly across CKD stages (p>0.05). After adjustment for potential confounders, factors independently associated with malnutrition included a history of stroke (adjusted OR = 85.23, 95% Cl: 19.23-377.7), underweight and obese body habitus, weight loss within the preceding 4 weeks (adjusted OR = 7.55, 95% Cl: 2.92-19.51), reduced or very low dietary intake (adjusted OR = 46.42, 95% Cl: 10.39-207.38), impaired access to food (adjusted OR = 10.63, 95% Cl: 2.88-39.23), higher serum creatinine levels (adjusted OR = 1.86, 95% Cl: 1.19-1.43), and lower lymphocyte counts (adjusted OR = 0.93, 95% Cl: 0.89-0.97). Conclusion: Malnutrition is highly prevalent among patients with CKD stages 3–5 prior to renal replacement therapy and is more strongly associated with comorbid conditions, body habitus, weight change, and dietary factors than with CKD stage itself. These findings highlight the importance of early nutritional screening and intervention beginning in the early stages of CKD.
