Doctors working in famine relief commonly use the weight:height ratio and the circumference of the mid-upper arm to assess the nutritional state of children under 5. Threshold values indicating moderate and severe malnutrition are usually taken as 80% and 70%, respectively, of the expected weight:height ratio and arm circumferences of 13.5 cm and 12.5 cm, respectively. A study of 1260 children aged 1-5 showed that the thresholds of these two variables yielded significantly different proportions of children with malnutrition, the proportion being much larger when arm circumference was used as the criterion. Adjusting the thresholds would result in closer correspondence between the two variables.
参与饥荒救济工作的医生通常会使用体重与身高的比值以及上臂中部的周长来评估5岁以下儿童的营养状况。表明中度和重度营养不良的阈值通常分别取预期体重与身高比值的80%和70%，上臂周长的阈值分别为13.5厘米和12.5厘米。一项针对1260名1至5岁儿童的研究表明，这两个变量的阈值得出的营养不良儿童比例存在显著差异，以上臂周长作为标准时比例要大得多。调整阈值会使这两个变量之间的对应关系更紧密。
