This study investigated the hypothesis that specific types of maternal touch that might promote infant growth are reduced in cases of failure to thrive (FTT) and tested reports that maternal physical interaction and physical affection are diminished in FTT.
Frequencies of operationally defined maternal touch categories were scored by blinded raters from videotaped mother-child feeding and play interactions of 21 children, aged 9 to 19 months, with FTT and 18 normally growing comparison children. After scoring and statistical analyses were completed, investigators unblinded to group status and clinical data reviewed the videotapes of the dyads with the lowest touch scores.
Mothers of children with FTT provided less matter-of-fact touch in feeding (p = .017) and unintentional touch in play (p = .048) than the comparison group, and there was a trend (p = .082) for them to provide less proprioceptive stimulation in play. Unblinded case reviews indicate that, among children with FTT, extremely infrequent touch signals a marked touch aversion by either the mother or child.
Types of maternal touch that may promote growth or facilitate feeding are reduced in FTT, due, in extreme cases, to maternal or child touch aversion. Clinicians evaluating FTT should be alert to very infrequent touch in the mother-child interaction and consider whether it may represent a maternal intolerance of physical contact with her infant or a problem with the infant's feeding competence.
本研究调查了以下假设，即可能促进婴儿生长的特定类型的母亲触摸在发育迟缓（FTT）病例中会减少，并检验了有关FTT中母亲身体互动和身体亲昵行为减少的报告。
由不知情的评分者对21名9至19个月大患有FTT的儿童和18名正常生长的对照儿童的母子喂养及玩耍互动录像中的母亲触摸类别进行操作性定义评分。在完成评分和统计分析后，了解分组情况和临床数据的研究人员查看了触摸分数最低的二元组的录像。
与对照组相比，FTT儿童的母亲在喂养时提供的实际触摸较少（p = 0.017），在玩耍时提供的无意触摸较少（p = 0.048），并且在玩耍时提供较少本体感觉刺激存在一种趋势（p = 0.082）。非盲法病例审查表明，在FTT儿童中，极少的触摸表明母亲或孩子存在明显的触摸厌恶。
FTT中可能促进生长或便于喂养的母亲触摸类型减少，在极端情况下，这是由于母亲或孩子的触摸厌恶所致。评估FTT的临床医生应警惕母子互动中极少的触摸，并考虑这是否可能代表母亲对与婴儿身体接触的不耐受或婴儿喂养能力方面的问题。
