Objective: few studies have verified longitudinally the evolution of the nutritional status of patients with cystic fibrosis. The objective of this study is to follow the evolution of the nutritional status, body composition and energy consumption, macronutrients and micronutrients ingested by children and adolescents by means of nutritional interventions at the Clinic of Cystic Fibrosis/Pediatric Pneumology of the Department of Pediatrics of Universidade Federal de São Paulo. Methods: 18 patients were involved in this study, thirteen males and five females with ages ranging from 0.3 to 18.4 years. We performed three evaluations: evaluation 1 (M1- prenutritional intervention), M2 after 6 months, and M3 after 12 months. In these three instances we verified: the z score for weight/age, weight/height and height/age and the calculation of a 3-day diet record. We verified the body composition (anthropometry) in M1 and M3. The nutritional interventions were hypercaloric, hyperproteic, with adequate amount of ingested macronutrients and micronutrients.Results: we observed an increase in the z score for height/age (M1=-1.07; M2=-0.69; M3=-0.50) and fat-free mass after the nutritional interventions, without improvement in the z score for weight/height and fat mass. We verified an increase in the energy intake during M2 (139%) and M3 (132%) compared to M1 (106%). Remarkable increase in the intake of protein, calcium, iron and vitamin C by the patients was found. The occurrence of anemia was found in 44% (8/18) of the patients.Conclusion: the improvement of the z score in height/age and fat-free mass was probably due to the increase in energy consumption after the nutritional intervention. A significant improvement in the z score for weight/height and fat mass was not found, probably due to a gain in height and fat-free mass.
