OBJECTIVE
To assess the use of mid-upper arm circumference (MUAC) for identification of overweight and overfatness in rural South African children and adolescents.
METHODS
Anthropometric data (weight, height, MUAC and % body fat) from a cross-sectional sample of 978 black South African 5-14-year-olds were analysed. Receiver operating characteristic (ROC) curve analysis determined the validity of MUAC as a proxy for determining overweight and overfatness.
FINDINGS
Area under the curve (AUC) results were generally high. Boys and girls aged 10-14 years had ROC-AUC for overfatness classed as 'excellent', 0.97 and 0.98 respectively. Cut-points in the MUAC distribution which optimised the ROC-AUC for identification of overfatness and obesity were determined for boys and girls aged 5-9 and 10-14 years, and had high sensitivity and specificity.
CONCLUSIONS
MUAC may have potential for clinical and surveillance applications as an accurate yet simple and widely available indicator of overweight and overfatness in children and adolescents in resource-poor settings.
目的
评估中上臂围（MUAC）在识别南非农村儿童和青少年超重和肥胖中的作用。
方法
对横断面样本中 978 名南非黑人 5-14 岁儿童的体重、身高、MUAC 和体脂%等人体测量数据进行了分析。接收者操作特征（ROC）曲线分析确定了 MUAC 作为超重和肥胖替代指标的有效性。
结果
曲线下面积（AUC）的结果普遍较高。10-14 岁的男孩和女孩的体脂过多分类的 ROC-AUC 被评为“优秀”，分别为 0.97 和 0.98。确定了 5-9 岁和 10-14 岁男孩和女孩 MUAC 分布中切点，以优化 ROC-AUC 识别肥胖和超重的效果，具有较高的灵敏度和特异性。
结论
MUAC 可能具有临床和监测应用的潜力，作为资源匮乏环境中儿童和青少年超重和肥胖的一种准确、简单且广泛可用的指标。
