The presence of a defined set of behaviors was examined in 67 hospitalized infants, 3-24 months old; 17 with organic failure-to-thrive (OFTT), 17 with nonorganic failure-to-thrive (NOFTT), and 33 with no signs of failure-to-thrive. The usefulness of assessing these behaviors to distinguish nonorganic from organic failure-to-thrive infants was evaluated. The frequency of behaviors per infant as well as the intensity of behaviors was greater for NOFTT. The order of decreasing frequency of behaviors was similar in both OFTT and NOFTT infants. Four of the 7 most prevalent behaviors occurred significantly more frequently in NOFTT than OFTT infants. The presence of these behaviors does not rule in NOFTT or rule out OFTT. However, when a number of the behaviors are present, particularly if they occur in high intensity, and when no organic disease is found, a diagnosis of NOFTT is suggested. Response to appropriate treatment remains the most reliable confirmation of the diagnosis.
对67名3至24个月大的住院婴儿进行了特定行为集的观察；其中17名患有器质性发育不良（OFTT），17名患有非器质性发育不良（NOFTT），33名无发育不良迹象。评估了这些行为对于区分非器质性和器质性发育不良婴儿的有用性。NOFTT婴儿的个体行为频率以及行为强度更高。OFTT和NOFTT婴儿中行为频率递减的顺序相似。7种最常见的行为中有4种在NOFTT婴儿中出现的频率明显高于OFTT婴儿。这些行为的存在既不能确诊NOFTT，也不能排除OFTT。然而，当出现多种行为时，特别是如果它们以高强度出现，并且未发现器质性疾病时，则提示诊断为NOFTT。对适当治疗的反应仍然是诊断的最可靠确认。
