Background: Enteral nutrition therapy (ENT) is intended to restore the nutritional status of patients.

Objective: The objective of this study was to evaluate the biochemical and nutritional profile of hospitalized patients with exclusive enteral nutrition.

Methods: It is a longitudinal study, with a sample of 42 hospitalized young and elder adults, with exclusive ENT, for at least seven days. The patients were submitted to nutritional, anthropometric (Body Mass Index, corrected arm muscle area and arm muscle circumference) and biochemical evaluation as albumin, hemoglobin, C-reactive protein, vitamin C, Iron, Zinc and Copper serum.

Results and Discussion: It was observed that anthropometric parameters such as weight, BMI, muscle area and circumference increased during hospitalization time only in the elderly (P= 0.016; P=0.018; P = 0.021; P = 0.020). The percentage of adequacy in energy, protein and micronutrients with vitamin C, iron, zinc and copper were adequate during hospitalization for both age groups, according to the estimated average needs. Serum levels of these micronutrients were within normal values for both age groups, with the exception of zinc, which decreased during hospitalization in the elderly. This may be associated with the greater need for this mineral in this age group or with a implicate in its absorption.

Conclusion: The ENT influence the weight and muscle mass gain in hospitalized elderly patients and, although the appropriate administration of micronutrients, the absorption of zinc was affected. Therefore, monitoring of enteral nutrition is essential in order to avoid worsening nutritional status during hospitalization.
