| Abstract (English): |
Objective: To evaluate sonographic measurements of visceral and subcutaneous fat in children, and to investigate the usefulness of preperitoneal fat (PF) and the abdominal wall fat index (AFI) as parameters to determine visceral fat and presence of nonalcoholic fatty liver disease (NAFLD) in obese children. Materials and Methods: A case-control study of a sample including 44 children (22 cases and 22 controls) matched by sex and age. The Student t test and the Fisher exact test were utilized in the descriptive and bivariate analysis. Results: The sonographic parameters evaluated - subcutaneous cell tissue, PF and intraperitoneal fat, and NAFLD - presented high statistical association with body mass index. NAFLD was observed in eight obese patients (36.36%), and PF and AFI were the variables with highest statistical significance, with p < 0.0001. Conclusion: Ultrasonography is useful tool in the differentiation and quantification of visceral and subcutaneous fat in children. The measures of PF and AFI are useful in the assessment of visceral fat and NAFLD in obese children. [ABSTRACT FROM AUTHOR] |

Objetivo: Avaliar as medidas ultrassonográficas da gordura visceral e subcutánea em crianças e testar se a gordura pré-peritoneal (GPP) e o índice de gordura da parede abdominal (IGPA) sao parámetros úteis para determinar a gordura visceral e a presença de doença hepática gordurosa nao alcoólica (DHGNA) em crianças obesas. Materiais e Métodos: Estudo tipo caso-controle, com uma amostra de 44 crianças, sendo 22 casos e 22 controles, pareados conforme sexo e idade. Os resultados foram analisados de forma descritiva e bivariada, com teste t de Student e teste exato de Fischer. Resultados: Os parámetros ultrassonográficos avaliados - tecido celular subcutáneo, GPP e gorduras intraperitoneais, e DHGNA - obtiveram elevada associaçao estatística com o índice de massa corpórea. A DHGNA foi observada em oito pacientes obesos (36,36%), sendo que a GPP e o IGPA foram as variáveis com maior significáncia estatística, com valor de p < 0,0001. Conclusâo: A ultrassonografia permite diferenciar e quantificar a gordura visceral e subcutánea nas crianças. As medidas da GPP e do IGPA sao úteis para a avaliaçao da gordura visceral e DHGNA em crianças obesas. [ABSTRACT FROM AUTHOR] |
