Infants and children with suspected caloric-deprivation failure to thrive (CDFTT) are commonly hospitalized to confirm the diagnosis. In the hospital, weight gain at an accelerated rate is used as the primary diagnostic criterion. We evaluated how soon patients with CDFTT began to gain weight and if the speed with which the patients started to gain weight was age dependent. Of 476 patients with growth problems, 57 met the criteria for inclusion in the study. We developed the concept of the "growth quotient," which expresses the patient's rate of growth. We found that almost all 57 children started to grow in less than two weeks, and those less than 6 months old usually began to gain weight in only two to three days. Older infants and children with CDFTT often had initial corrective growth rates equal to or greater than those of young infants.
疑似热量剥夺性发育不良（CDFTT）的婴幼儿通常会住院以确诊。在医院里，体重加速增加被用作主要诊断标准。我们评估了CDFTT患者多久开始体重增加，以及患者开始体重增加的速度是否与年龄有关。在476名有生长问题的患者中，57名符合纳入该研究的标准。我们提出了“生长商数”的概念，它表示患者的生长速度。我们发现，几乎所有57名儿童在不到两周的时间内开始生长，而那些不到6个月大的儿童通常仅在两到三天内就开始体重增加。年龄较大的CDFTT婴幼儿最初的矫正生长速度通常等于或高于小婴儿。
