Rationale: Poor quality of life and inadequate dietary protein intake are common in patients with CKD on maintenance hemodialysis. Examining their association may help guide nutritional interventions to improve patient outcomes.

Methods: A cross-sectional study was conducted from March to August 2025 at the Department of Nephrology and Hemodialysis, University Medical Center Ho Chi Minh City, Vietnam. Patients with CKD on maintenance hemodialysis 2–3 times weekly for at least 3 months were consecutively recruited. Dietary protein intake was assessed using a validated semi-quantitative FFQ for the Vietnamese population, and quality of life was measured with the KDQOL-36. Ethical approval was obtained (No. 182/ĐHYD-HĐĐĐ; January 9, 2025).

Results: Among 91 participants, 56.0% were female, and mean age was 62.0 ± 18.1 years. Mean daily protein intake was 43.6 ± 16.1 g/day (range 14.5-102.1), and mean overall KDQOL-36 score was 57.42 ± 9.65. Higher protein intake was significantly associated with better overall quality of life (β = 0.197, 95% CI 0.069–0.324; p = 0.003), particularly in the domains of physical health (β = 0.196, 95% CI 0.043–0.349; p = 0.013), disease burden (β = 0.342, 95% CI 0.007–0.676; p = 0.046), and symptom burden (β = 0.237, 95% CI 0.096–0.377; p = 0.001). No significant associations were found for mental health or effects of kidney disease.

Conclusion: These findings support routine nutritional assessment, individualized nutrition care, and increased attention to quality of life in the comprehensive management of this population.
