Introduction: Anorexia and dietary restrictions (potassium, phosphorous and sodium) are very common in dialysis patients, which in turn limits the frequency and variety of healthy food consumption. Poor diet quality could be associated with greater protein energy wasting (PEW), which is associated with worse outcome and patient survival.
Methods: Analytical cross-sectional study; 66 dialysis patients were included, and underwent a complete clinical and nutritional evaluations. Diet quality was evaluated using the Food Consumption Quality Survey (Mini-ECCA v.2). PEW was determined by means of subjective global assessment; body composition was evaluated by spectroscopic bioimpedance.
Results: The average age of the patients was 42 ± 14 years. Only 12% had a healthy diet, 29% requires to improve and 59% unhealthy. Results of the nutritional status according to the quality of diet are shown in the table. In multivariate analysis, a better diet quality (adjusted for age, time on dialysis and diabetes mellitus) predicted better nutritional status only in women [B= -0.41, (-1.52 to -0.02)], whereas in men no significant model was found.
Conclusions: Patients with a healthy diet had a better score of nutritional status as well as a higher lean tissue index. A better quality of diet significantly predicted a better nutritional status in women.
