To verify the association between anthropometric indicators and body fat percentage (F %) estimated by dual X-ray absorptiometry (DXA) and air displacement plethysmography (ADP) in children and adolescents diagnosed with HIV. This cross-sectional study was carried out with 62 children and adolescents with HIV (8 to 15 years). F % was estimated by DXA and ADP. Anthropometric indicators were skinfolds (abdominal, triceps, subscapular, calf); perimeter relaxed arm (PRA), waist circumference (WC),

Linear regressions were performed with 5% significance level. In boys (R² adj = 0.38 to R² adj = 0.67) and girls (R² adj = 0.41 to R² adj = 0.57), all anthropometric indicators were associated with F% estimated by DXA. For boys, skinfolds were associated with F % estimated by ADP (R² adj = 0.18 to R² adj = 0.35). In girls, skinfolds (R² adj = 0.27 to R² adj = 0.44, BMI (R² adj = 0.31), PRA (R² adj = 0.36) and WC (R² adj = 0.26) were associated to F % by ADP. Abdominal skinfold was the indicator that most explained the variation in F % measured by DXA and ADP in both sexes. Anthropometric indicators are strongly associated with body fat, measured by reference methods, and can assist health professionals in monitoring the health of children and adolescents with HIV.
