In a limited controlled sample, the performance of the middle upper arm circumference (MUAC) was compared to those of standard indices (weight for age, height for age and weight for height), using 90 children aged one to four years living in a high density town near Harare, Zimbabwe. Using a cut off point of 15,5 cm, the MUAC performed best in relation to the weight for age (sensitivity 66,7 pc (95 pc confidence interval (CI) 53,3-80,0 pc), specificity 76,2 pc (95 pc CI 61,7-80,5 pc)) than to any other standard index. Nevertheless, this performance was unsatisfactory because about 30 in every 100 (28,9 pc) children would have been inaccurately identified as healthy or diseased. Although we do not have evidence from the present study to recommend the use of the MUAC in identifying children who are malnourished and living in similar high density areas, the MUAC may be applicable to children living in areas of higher prevalence of malnutrition.
在一个有限的对照样本中，对90名年龄在1至4岁、生活在津巴布韦哈拉雷附近一个高密度城镇的儿童，将上臂中部周长（MUAC）的表现与标准指标（年龄别体重、年龄别身高和身高别体重）进行了比较。使用15.5厘米的切点，MUAC相对于年龄别体重表现最佳（敏感性66.7%（95%置信区间（CI）53.3 - 80.0%），特异性76.2%（95% CI 61.7 - 80.5%）），优于任何其他标准指标。然而，这种表现并不令人满意，因为每100名儿童中约有30名（28.9%）会被错误地判定为健康或患病。尽管我们没有本研究的证据来推荐使用MUAC识别营养不良且生活在类似高密度地区的儿童，但MUAC可能适用于营养不良患病率较高地区的儿童。
