Weight and height绘制体重身高比例图are usually plotted on standardized growth charts.标准生长曲线图上常常包括体重和身高Once a child’s placement has been determined on the一旦一个儿童在生长曲线图上的位置被确定growth chart this number can be converted to what is此数字就可以转换成所谓Zknown as a Z score. A Z score is a numerical summary一个Z就是一个数字摘要of each child’s placement relative to a reference它总结了每个儿童相对于参考人口的定位population and are used to compare and assess data可以用来比较和评估不同年龄不同性别between different ages and genders. Once a Z score之间的数据 一旦Z确定了is determined a child can be placed on what is儿童就可定位在known as a standard, normal distribution graph.一个标准的正态分布图上This graph puts the average variable that is being这个图表的中心是被测量的平均变量measured in the centre of a chart, any child任何身高或体重Z 超过2个标准差的儿童whose height or weight Z score is more than 2无论其Z值是高于平均值standard deviations greater or less than the mean is或者低于平均值considered to have significant growth abnormalities.均被视为明显的异常生长Thus is the child fell 2 standard deviations below the这就是为什么Z低于平均值的2个标准差mean he or she would be considered to be malnourished.的儿童会被视为营养不良However, studies have shown that simple weight,然而研究表明 简单的体重和身高测量height measurements are often inaccurate depending往往是不准确的其数据也要取决于on the type of tumor such as large solid tumors.肿瘤类型,比如大型实体肿瘤Other practices include tracking voluntary food intake其他做法有跟踪采食量and comparing intake to the required or将其摄入量与所需或推荐准则相比较recommended guidelines. If the child was eating如果儿童摄入的能量低于其预计能量less than 70% of his or her estimated energy需求的70%那么requirements then he or she would be considered将被视为营养不良malnourished. Another way is to take anthropometric另一种方法是对肱三头肌皮褶厚度measures of the tricep skin fold thickness to进行人体测量,以确定人体内脂肪determine adipose or fat energy reserves.或脂肪的能量储备If less than the 5th percentile for age and测量值不足其年龄和性别水平sex the patient would be considered malnourished.所需脂肪的百分之五的患者 将被视为营养不良 Article/201412/350966
