Abstract: Renal disease—nephritis, nephrotic syndrome, or nephropathy—is one of ten leading causes of death in Taiwan. Taiwan has the highest incidence of renal disease in the world, resulting in widespread use of hemodialysis. However, patients on long-term hemodialysis are likely to develop malnutrition, which increases the mortality rate. In this study, the mean values of nutritional status in hemodialysis patients were lower than that in NTU hospital organizations. Therefore, it is necessary to understand the daily dietary intake and extra food intake of patients on hemodialysis to improve their nutritional status. Using a questionnaire survey, 118 hemodialysis patients were selected and 98.3 percent are available. We explored the associations between dietary behavior, nutrient intake, and nutritional status using subjective global assessment (SGA), 24-hour dietary recall, and dietary frequency questionnaire, and using statistical analyses, including Pearson’s correlation analysis, the t-test, and analysis of variance (ANOVA). Lower nutrient intake was associated with worse nutritional status; patient dietary behavior affected nutrient intake and nutritional status; there were statistically significant differences between patients in dietary behaviors, age, exercise habits, dietician guidance, education, religion, marital status, occupation, average personal income, the frequency of dialysis, and eating pattern. The findings of this study are useful to medical staff who provide hemodialysis patients with dietary advice and nutritional health education.
