目前，约有10%的婴儿体重长度超过其年龄和性别的第95百分位，这使他们在成长过程中面临肥胖的风险。在一项预防肥胖的试点研究中，初产母亲和她们的新生儿被随机分配到对照组或抚慰/睡眠干预组。在此之前，已经证明这种干预有助于降低1年的体重长度百分位数；本研究的目的是检查在干预期间收集的婴儿行为日记数据。马尔可夫模型被用来描述婴儿在3岁和16周时的行为转变模式。研究结果显示，体重较重的母亲更有可能在婴儿哭闹后进行喂养。干预增加了婴儿从大惊小怪/哭闹状态过渡到清醒/平静状态的可能性。对哭闹反应的较短进食延迟与随后较高的体重状态相关。这项研究提供了初步证据，表明婴儿从哭闹/哭闹的转变具有个体间差异的特征，是可改变的，并且与体重结果有关，这表明它们可能是早期行为肥胖干预的有希望的目标，并强调了本研究中使用的方法作为评估此类干预影响的适当和创新工具。
Currently, about 10% of infants have a weight for length greater than the 95th percentile for their age and sex, which puts them at risk for obesity as they grow. In a pilot obesity prevention study, primiparous mothers and their newborn infants were randomly assigned to a control group or a Soothe/Sleep intervention. Previously, it has been demonstrated that this intervention contributed to lower weight-for-length percentiles at 1 year; the aim of the present study was to examine infant behavior diary data collected during the intervention. Markov modeling was used to characterize infants’ patterns of behavioral transitions at ages 3 and 16 weeks. Results showed that heavier mothers were more likely to follow their infants’ fussing/crying episodes with a feeding. The intervention increased infants’ likelihood of transitioning from a fussing/crying state to an awake/calm state. A shorter latency to feed in response to fussing/crying was associated with a higher subsequent weight status. This study provides preliminary evidence that infants’ transitions out of fussing/crying are characterized by inter-individual differences, are modifiable, and are linked to weight outcomes, suggesting that they may be promising targets for early behavioral obesity interventions, and highlighting the methodology used in this study as an appropriate and innovative tool to assess the impact of such interventions.
