Abstrakt:	Objective: This study aimed to evaluate the effect of a nutritional intervention, based on the transtheoretical model, on the metabolic markers and dietary intake of individuals undergoing hemodialysis (HD). Methods: Intervention study at a nephrology clinic includes 83 individuals undergoing HD, over a period of 4 months. The nutritional intervention based on the transtheoretical model was composed of two group meetings and three individual ones, with delivery of personalized food plans and nutritional education activities. Anthropometry, dietary intake, metabolic markers, and stage of behavior change were evaluated before and after nutritional intervention. Results: There was a significant change from the stage of contemplation to the stage of action, after the intervention (P < .001). There was a significant reduction in serum concentrations of creatinine and predialysis and postdialysis urea (P < .001). Hyperphosphataemia and hyperkalemia in the group were also significantly reduced as were markers related to bone metabolism (P < .001). The markers of iron metabolism (P < .001), protein (P = .042), and globulin (P < .001) showed a significant increase. Regarding food consumption, the caloric intakes (P = .034), cholesterol (P = .034), protein, and lipid as well as intake of iron, phosphorus, potassium, copper, and vitamin C (P < .001) were significantly higher after intervention. Conclusions: The nutritional intervention based on the transtheoretical model promoted a change in the behavior of individuals undergoing HD, with an important improvement in their metabolic control. This can be explained by the significant change in the intake of calories, macronutrients, and micronutrients, as well as adequate use of phosphorus binders, indicating the crucial role of nutrition in this group.
