Determinação de risco nutricional e desnutrição por antropometria em crianças e adolescentes com cirrose Nutritional risk and malnutrition determination by anthropometry in cirrhotic children and adolescents
Abstract
RACIONAL: A desnutrição é achado freqüente em adultos com cirrose, mas a prevalência de risco nutricional e de desnutrição é pouco conhecida em pacientes pediátricos. OBJETIVO: Avaliar a ocorrência de risco nutricional e desnutrição em pacientes pediátricos com cirrose atendidos regularmente no Setor de Gastroenterologia Pediátrica do Hospital de Clínicas de Porto Alegre, RS. MÉTODOS: Estudo transversal com 42 crianças e adolescentes cirróticos com idades entre 3 meses e 18 anos. O estado nutricional foi determinado por escores Z de peso para idade, estatura para idade, índice de massa corporal e percentis para a prega cutânea tricipital e circunferência muscular do braço. Consideraram-se pacientes em risco nutricional aqueles com escore BACKGROUND: The malnutrition is a frequent finding in adults with cirrhosis, but the prevalence of nutritional risk and malnutrition is little known in pediatric patients. AIM: To evaluate through anthropometry the presence of nutritional risk and malnutrition in cirrhotic pediatric patients regularly attended at the Pediatric Gastroenterology Service of "Hospital de Clínicas" of Porto Alegre, RS, Brazil. METHODS: Cross-sectional study with 42 cirrhotic children and adolescents aged between 3 months and 18 years. The nutritional evaluation was made by the determination of the weight/age, height/age, body mass index and triceps skinfold thickness and arm muscle circumference measurements. Patients considered in nutritional risk were < -1,28 Z score which corresponds to <10th percentile, and those under -2,0 Z and <3th percentile were in malnutrition status. According to Child-Pugh criteria, 22 patients were classified as A (mild severity), 15 (moderate) B and 5 C (intense). RESULTS: The mean weight/age, height/age and body mass index Z scores were, respectively, - 0,38 ± 1,4 SD, - 0,83 ± 1,16 SD and 0,17 ± 1,3 SD. Patients in nutritional risk were 3/42 (weight/age), 8/42 (height/age), 12/37 (triceps skinfold thickness), 9/37 (arm muscle circumference), 2/38 (body mass index); in malnutrition status were 6/42 (weight/age), 7/42 (height/age), 4/37 (triceps skinfold thickness) and 4/37 (arm muscle circumference) and 3/38 (body mass index). CONCLUSION: The prevalence of nutritional risk was 32.4% and chronic malnutrition was 16.7%. The index which better reflected the nutritional risk in these patients was triceps skinfold thickness. Chronic malnutrition status occurrence was greater in the height/age index.
