BACKGROUND: Body fat assessment is needed in individuals with HIV. The objective was to identify the discriminatory capacity of the abdominal skinfold (ASF) tricipital skinfold (TSF), subscapular fold (SSF), calf skinfold (CSF), body adiposity index (BAI), body mass index, conicity index (IC), mid-upper arm circumference (MUAC), waist circumference (WC), perimeter of neck (PN) and waist-to-height ratio (WHtR) for high body fat in children and adolescents with HIV, compared Dual energy x-ray Absorciometry (DXA) and air displacement plethysmography (ADP).
METHODS: Descriptive study, cross - sectional study, with 65 children and adolescents with HIV by vertical transmission. Body fat was measured by DXA and ADP. Measures were measured by international standardization. The diagnostic properties for high body fat were assessed by area under the ROC curve (AUC).
RESULTS: For boys, having DXA as a reference for fat, ASF (AUC-0.920), TSF (AUC-0.792), SSF (AUC 0.766), CSF (AUC-0.866), BAI satisfactory discriminatory capacity. With ADP as the reference method, ASF (AUC-0.920), TSF (AUC-0.921), SSF (AUC-0.766), CSF (AUC-0.901), BAI (AUC- 0.756) and BMI (AUC- 0.699) presented satisfactory results. For girls, having DXA as a reference for fat, ASF (AUC- 0.838), TSF (AUC-0.842), SSF (AUC-0.840), CSF (AUC-0.887), BAI (AUC-0.846), and BMI (AUC-0.859) presented satisfactory discriminatory capacity. Assuming ADP as a reference for fat, ASF (AUC- (AUC-0.799), TSF (AUC-0.825), SSF (AUC-0.767), CSF (AUC-0.897), BAI 0.788), were satisfactory.
CONCLUSIONS: The ASF, TSF, SSF, CSF, BAI and BMI anthropometric indicators may be suggested as the most suitable for the detection of high body fat in children and adolescents with HIV.
