Infants are more vulnerable to malnutrition as compared with older children. Prevalence of severe wasting in Indian infants under 6 months of age (U6M) is 14.8% (National Family Health Survey 4, 2015-2016). Weight for length z-score (WLZ) and mid-upper arm circumference (MUAC) are 2 anthropometric parameters for detecting severe acute malnutrition (SAM) in children aged 6 months to 5 years. But in infants U6M, currently no accepted MUAC criteria are present for SAM. Calculating WLZ is practically difficult and cumbersome as compared with measuring MUAC. We tried to find out whether MUAC can be used in detecting SAM in infants aged 1 to 6 months also. The area under ROC curve was computed to evaluate the accuracy of MUAC in detecting SAM (taking WLZ as reference test). Level of accuracy was found out to be "good." Optimal MUAC cut-off with best diagnostic accuracy was identified as ≤11.5 cm, using the highest Youden index of 0.55.
与大龄儿童相比，婴儿更容易患营养不良。印度6个月以下婴儿（U6M）的重度消瘦患病率为14.8%（2015 - 2016年第四次全国家庭健康调查）。身长别体重Z评分（WLZ）和上臂中部周长（MUAC）是用于检测6个月至5岁儿童重度急性营养不良（SAM）的两个人体测量参数。但在6个月以下婴儿中，目前尚无公认的用于检测SAM的MUAC标准。与测量MUAC相比，计算WLZ实际操作困难且繁琐。我们试图探究MUAC是否也可用于检测1至6个月婴儿的SAM。计算ROC曲线下面积以评估MUAC检测SAM的准确性（以WLZ作为参考测试）。发现准确性水平为“良好”。使用最高约登指数0.55，确定具有最佳诊断准确性的最佳MUAC临界值为≤11.5厘米。
