目的探讨南非农村儿童和青少年中上臂围（MUAC）在超重和过胖诊断中的应用。方法分析978名5-14岁南非黑人的横断面样本的人体测量数据（体重、身高、MUAC和体脂%）。受试者工作特征（ROC）曲线分析确定了MUAC作为确定超重和过胖的替代指标的有效性。曲线下面积（AUC）结果普遍较高。10-14岁男孩和女孩的ROC-AUC为“优秀”，分别为0.97和0.98。在5-9岁和10-14岁的男孩和女孩中确定了MUAC分布的切割点，该切割点优化了ROC-AUC用于识别过度肥胖和肥胖，具有高灵敏度和特异性。结论MUAC作为资源贫乏地区儿童和青少年超重和过胖的一种准确、简单和广泛可用的指标，可能具有临床和监测应用潜力。
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.
