ABSTRACT

Introduction: protein-energy malnutrition is the result of the imbalance between the needs of the organism and nutrient intake. It causes metabolic changes that increase morbi-mortality.
Objective: to check the recovery of somatometric indicators and their correspondence with the variables of antioxidant defense during the renourishment of moderately undernourished rats.
Methods: An experimental prospective study was performed with a sample of 64 male Wistar albino rats at weaning (32 control and the rest of the experimental one) through a complete renourishment model for three weeks, after quantitative restrictions on 75 % of the daily requirement for their age during 28 days. Somatometric variables were determined and antioxidant defense indicators and their association, by Pearson's correlation coefficient. It was estimated the mean, the standard deviation and the t-Student test.
Results: during renourishment it was observed recovery of body weight of the experimental group (256.11 g) without reaching the normality of the control (270.98 g), size was increased (18,43 cm) and the length of the tail (14, 01 cm) of the experimental one without reaching the control (20.07 cm) and (15.05 cm) respectively. The weight of the organs was increased, standing out the liver (10.71 g) and the small intestine (4.41 g) of the experimental one without reaching control values (11.77 g) and (4.75 g) respectively.
Conclusions: alterations of somatometric indicators occurred in undernourishment are reversed during renourishment which is associated with the progressive increase in antioxidant defenses.
