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.
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.
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.
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.
评估儿童内脏脂肪和皮下脂肪的超声测量方法，并研究腹膜前脂肪（PF）和腹壁脂肪指数（AFI）作为确定肥胖儿童内脏脂肪和非酒精性脂肪性肝病（NAFLD）存在情况参数的实用性。
一项病例对照研究，样本包括44名按性别和年龄匹配的儿童（22例病例和22例对照）。描述性和双变量分析采用Student t检验和Fisher精确检验。
所评估的超声参数——皮下细胞组织、PF和腹膜内脂肪以及NAFLD——与体重指数呈现高度统计学关联。在8名肥胖患者（36.36%）中观察到NAFLD，PF和AFI是具有最高统计学意义的变量，p < 0.0001。
超声检查是区分和量化儿童内脏脂肪和皮下脂肪的有用工具。PF和AFI测量值在评估肥胖儿童的内脏脂肪和NAFLD方面有用。
