Resumo
Introdução: O consumo alimentar anti-inflamatório apresenta propriedades de uma dieta antioxidante, sendo ele considerado uma estratégia de prevenção e combate ao estresse oxidativo. Um método de avaliação desse potencial antioxidante do consumo alimentar é através da Capacidade Antioxidante Total da Dieta (dCAT). Objetivo: Avaliar a dCAT e sua associação com o estado nutricional, risco de desnutrição e inflamação em crianças e adolescentes hospitalizados. Metodologia: Estudo transversal realizado com crianças e adolescentes, admitidos no setor de pediatria de um hospital filantrópico de Viçosa – MG, Brasil, entre 2014 e 2019. O risco nutricional foi avaliado através do Screening Tool for Risk on Nutritional Status and Growth (STRONGKids). Medidas de peso e comprimento/estatura foram aferidas e índices antropométricos avaliados. A dCAT foi obtida através uma planilha em Microsoft Excel® que considerava os valores de dCAT de cada alimento, baseado no consumo alimentar do dia anterior à realização da triagem nutricional (Recordatório de 24 horas - R24h). Dados de bioquímicos foram coletados do prontuário médico. Os testes Kolmogorov- Smirnov, qui-quadrado de Pearson, teste exato de Fisher e análises de regressão logística foram realizadas, adotando-se p<0,05. Resultados: Participaram do estudo 403 pacientes (54,8% sexo masculino), com idade mediana de 3,4 (1 - 14) anos. A prevalência de risco nutricional foi de 80,1% (médio ou alto risco), de déficit nutricional entre 6,0% e 7,4%, de acordo com o índice antropométrico avaliado, e de anemia 59,7%, PCR alterada 75,6%. A dCAT se correlacionou inversamente com a pontuação do STRONGKids e diretamente com hemoglobina. Aqueles que estavam no maiores tercis de dCAT apresentaram menores chances de déficits antropométricos pelos índices P/I, E/I e IMC/I e o parâmetro inflamatório avaliado - PCR não demonstrou qualquer associação. Conclusão: A maior dCAT associou-se com o menor risco nutricional e melhor estado nutricional em crianças e adolescentes hospitalizados, indicando a necessidade do diagnóstico nutricional precoce, incluindo análise do consumo alimentar, bem como da promoção da alimentação adequada e saudável também em ambiente hospitalar.Palavras-chave: Desnutrição.

Introduction: Anti-inflammatory food consumption has the properties of an antioxidant diet, which is considered a strategy to prevent and combat oxidative stress. One method of evaluating this antioxidant potential in food consumption is through the Diet's Total Antioxidant Capacity (dTAC). Objective: To evaluate dTAC and its association with nutritional status, risk of malnutrition and inflammation in hospitalized children and adolescents. Methodology: Cross- sectional study conducted with children and adolescents admitted to the pediatric sector of a philanthropic hospital in Viçosa – MG, Brazil, between 2014 and 2019. Nutritional risk was assessed using the Screening Tool for Risk on Nutritional Status and Growth (STRONGKids) . Weight and length/height measurements were taken and anthropometric indices assessed. The dCAT was obtained using a Microsoft Excel® spreadsheet that considered the dTAC values of each food, based on the food consumption of the day before the nutritional screening (24-hour recall - R24h). Biochemical data were collected from the medical record. Kolmogorov- Smirnov, Pearson's chi-square, Fisher's exact test and logistic regression analyzes were performed, adopting p< 0,05. Results: The study included 403 patients (54.8% male), with a median age of 3.4 (1 - 14) years. The prevalence of nutritional risk was 80.1% (medium or high risk), of nutritional deficit between 6.0% and 7.4%, according to the anthropometric index evaluated, and of anemia 59.7%, altered CRP 75.6%. The dTAC correlated inversely with the STRONGKids score and directly with hemoglobin. Those who were in the highest tertiles of dCAT had lower chances of anthropometric deficits by the indices P/A, E/A and BMI/A and the inflammatory parameter evaluated - CRP did not show any association. Conclusion: The highest dCAT was associated with lower nutritional risk and better nutritional status in hospitalized children and adolescents, indicating the need for an early nutritional diagnosis, including analysis of food consumption, as well as the promotion of adequate and healthy nutrition in a hospital environment.Keywords: Malnutrition. Nutritional risk. STRONGKids. Antioxidant. Food intake. Childhood.
