Estimativa das necessidades energéticas em pacientes com doenÇa renal crÔnica

Abstract

Estimating the energy requirement of patients with chronic kidney disease is highly important for treating the nutritional disorders often seen in this population. According to the specific guidelines for patients with chronic kidney disease, the currently recommended daily energy intake varies from 30 to 40kcal/kg/day. However studies that investigated energy expenditure components of patients with chronic kidney disease suggested that the energy requirement may differ from the one proposed earlier, depending on overall clinical condition (i.e. presence of comorbidities), treatment modality and level of physical activity. With this perspective in mind, the present study aims to review the studies assessing energy expenditure focusing on two themes: (1) is the current energy recommendation for patients with chronic kidney disease adequate? (2) which predictive equation can be used when estimating the energy requirements of this population? Therefore, this review aims to help dietitians to estimate the energy needs of chronic kidney disease patients.
