To verify the association between anthropometric indicators and body fat percentage estimated by dual X-ray absorptiometry (DXA) and air displacement plethysmography (ADP) in children and adolescents diagnosed with human immunodeficiency virus (HIV). This cross-sectional study was carried out with 62 children and adolescents with HIV (aged 8 to 15 years). Body fat percentage was estimated by DXA and ADP. Anthropometric indicators were skinfolds (abdominal, triceps, subscapular, calf), perimeter relaxed arm (PRA), waist circumference (WC), perimeter neck, body mass index (BMI), waist-to-height ratio, conicity index, and body adiposity index. Linear regressions were performed with 5% significance level. In boys (adjusted () = 0.38 to = 0.67) and girls ( = 0.41 to = 0.57), all anthropometric indicators were associated with body fat percentage estimated by DXA. For boys, skinfolds were associated with body fat percentage estimated by ADP ( = 0.18 to = 0.35). In girls, skinfolds ( = 0.27 to = 0.44, BMI ( = 0.31), PRA ( = 0.36), and WC ( = 0.26) were associated to body fat percentage by ADP. Abdominal skinfold was the indicator that most explained the variation in body fat percentage 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.
为了验证人体免疫缺陷病毒（HIV）感染儿童和青少年的人体测量指标与双能 X 射线吸收法（DXA）和空气置换体积描记法（ADP）估计的体脂肪百分比之间的关联。这是一项横断面研究，共纳入 62 名 HIV 感染的儿童和青少年（年龄 8 至 15 岁）。使用 DXA 和 ADP 来估计体脂肪百分比。人体测量指标包括皮褶（腹部、三头肌、肩胛下、小腿）、放松臂周径（PRA）、腰围（WC）、颈周径、体重指数（BMI）、腰高比、锥度指数和身体脂肪指数。采用 5%显著水平进行线性回归分析。在男孩（调整后 () = 0.38 至 = 0.67）和女孩（ = 0.41 至 = 0.57）中，所有人体测量指标均与 DXA 估计的体脂肪百分比相关。对于男孩，皮褶与 ADP 估计的体脂肪百分比相关（ = 0.18 至 = 0.35）。对于女孩，皮褶（ = 0.27 至 = 0.44、BMI（ = 0.31）、PRA（ = 0.36）和 WC（ = 0.26）与 ADP 估计的体脂肪百分比相关。腹部皮褶是解释男女两性 DXA 和 ADP 测量的体脂肪百分比变化的最主要指标。人体测量指标与参考方法测量的体脂肪密切相关，可协助卫生专业人员监测 HIV 感染儿童和青少年的健康状况。
