The role of temperamental characteristics in accelerated and decelerated weight gain in normal infants has not been investigated previously except for differences in activity. The present study drew a random sample of 200 normal infants from a largely middle-class private practice. It found 24 infants who gained 30 or more percentile points in weight for length determinations between 6 and 12 months of age and 25 who lost 20 percentile points or more. These growth data were compared with contemporaneous findings on the Infant Temperament Questionnaire. Those gaining the most had significantly more difficult temperament ratings (p less than 0.05) and were perceived by their mothers as "more difficult than average" (p less than 0.001). Infants with the most decelerated growth were not temperamentally different from the general sample. Negative mood rather than low activity was the specific characteristic distinguishing the infants gaining the most (p = 0.006). Clinical experience would suggest that fussy infants are fed more to quiet them.
除了活动差异外，气质特征在正常婴儿体重加速和减速增加中的作用此前尚未得到研究。本研究从一个主要为中产阶级的私人诊所中随机抽取了200名正常婴儿作为样本。研究发现，在6至12个月大时进行身长测定时，有24名婴儿体重增加了30个百分点或更多，25名婴儿体重下降了20个百分点或更多。这些生长数据与同期婴儿气质问卷的调查结果进行了比较。体重增加最多的婴儿气质评定明显更难（p小于0.05），其母亲认为他们“比一般婴儿更难照料”（p小于0.001）。生长减速最多的婴儿在气质上与一般样本没有差异。区分体重增加最多的婴儿的具体特征是消极情绪而非低活动水平（p = 0.006）。临床经验表明，爱哭闹的婴儿会被喂食更多以使其安静下来。
