In the clinical settings, different anthropometric indicators like neck circumference (NC), waist circumference (WC), midupper arm circumference (MUAC), waist-to-height ratio (WHtR), and arm-to-height ratio (AHtR) have been suggested for evaluating overweight and obesity in children. The comparative ability of these indicators in Pakistan is yet unknown. This study is aimed at examining the validity of different anthropometric indicators of overweight and obesity simultaneously and at determining their superlative cut-off values that would correctly detect overweight and obesity in children. For this purpose, the dataset of anthropometric measurements height, weight, WC, MUAC, and NC of 5,964 Pakistani children, aged 5-12 years collected in a cross-sectional multiethnic anthropometric survey (MEAS), was used. Receiver operating characteristic (ROC) curve analysis was performed to assess the validity of different anthropometric indicators. The most sensitive and specific cut-off points, positive and negative predictive values of each indicator were also calculated. The results of the ROC curve indicated that all the studied indicators had a good performance but the indicators AHtR and WHtR had the highest value of the area under the curve (AUC) for the screening of children with overweight and obesity (AUC > 0.80). In the overall sample, AHtR, WHtR, MUAC, WC, and NC cut-off points indicative of overweight, in both boys and girls, were 0.14, 0.46, 18.41 cm, 62.86 cm, and 26.36 cm and 0.14, 0.47, 18.16 cm, 64.39 cm, and 26.54 cm, respectively; the corresponding values for obesity were 0.14, 0.47, 18.67 cm, 62.10 cm, and 26.36 cm and 0.14, 0.48, 20.19 cm, 64.39 cm, and 25.27 cm. We concluded that the sex-specific cut-off points for AHtR, WHtR, MUAC, WC, and NC can be used to diagnose overweight and obesity in Pakistani children.
在临床环境中，已经提出了多种人体测量指标，如颈围（NC）、腰围（WC）、中上臂围（MUAC）、腰高比（WHtR）和臂高比（AHtR），用于评估儿童超重和肥胖。这些指标在巴基斯坦的比较能力尚不清楚。本研究旨在同时检查超重和肥胖的不同人体测量指标的有效性，并确定其卓越的截断值，以正确检测儿童超重和肥胖。为此，使用了在跨种族人体测量调查（MEAS）中收集的 5964 名年龄在 5-12 岁的巴基斯坦儿童的身高、体重、WC、MUAC 和 NC 等人体测量测量数据集。进行了接收者操作特征（ROC）曲线分析，以评估不同人体测量指标的有效性。还计算了每个指标的最敏感和最特异截断值、阳性和阴性预测值。ROC 曲线的结果表明，所有研究指标的性能都很好，但指标 AHtR 和 WHtR 对筛查超重和肥胖儿童的曲线下面积（AUC）具有最高值（AUC>0.80）。在整个样本中，男孩和女孩超重的 AHtR、WHtR、MUAC、WC 和 NC 截断点分别为 0.14、0.46、18.41cm、62.86cm 和 26.36cm 和 0.14、0.47、18.16cm、64.39cm 和 26.54cm；肥胖的相应值分别为 0.14、0.47、18.67cm、62.10cm 和 26.36cm 和 0.14、0.48、20.19cm、64.39cm 和 25.27cm。我们得出结论，AHtR、WHtR、MUAC、WC 和 NC 的性别特异性截断值可用于诊断巴基斯坦儿童的超重和肥胖。
