摘要

虽然先前的研究已经确定了婴儿的行为信号饥饿、接受喂养、需要脱离喂养和饱腹，但需要进一步的研究来更好地了解婴儿表现出这些行为的程度的可变性，以及婴儿的喂养线索和照顾者对这些线索的反应如何随着时间的推移共同发展。目的研究婴儿在喂养过程中表现出的脱离和满足行为的数量和类型的年龄差异、母亲的喂养行为以及婴儿和母亲在第一年的行为对应关系。方法对227对1个月、2个月、4个月、6个月、9个月和12个月的婴儿在家中进行的自然奶瓶喂养互动进行录像。录像采用婴儿饱食行为（BABES）编码方案进行编码，以评估婴儿和母亲的相关行为。结果与1个月相比，婴儿在2个月时表现出更多的行为种类和行为总数。婴儿脱离和满足行为从婴儿期早期活动水平降低的行为特征转变为婴儿期后期对周围环境的警觉性、活跃性和兴趣增加。随着时间的推移，母亲们也表现出了行为上的发展转变——从更直接的参与到更多的口头反应——行为总数的减少。婴儿和母亲的行为率在1个月（r = -0.24, P = 0.061）或2个月（r = 0.15, P = 0.107）时无显著相关，但在4个月（r = 0.35, P < 0.001）、6个月（r = 0.21, P = 0.008）、9个月（r = 0.46, P < 0.001）和12个月（r = 0.26, P = 0.022）时呈正相关。研究结果强调了婴儿饱腹感交流和母亲反应性的年龄相关变化，以及婴儿和母亲的喂养行为共同发展并可能随着时间的推移变得更加一致的证据。该试验在clinicaltrials.gov注册为NCT04723264。

Co-Development of Infant Satiation Cues and Maternal Feeding Behaviors during Infancy

Background

Although prior research has identified infant behaviors signaling hunger, receptiveness to feeding, needs to disengage from feeding, and satiation, further research is needed to better understand variability in the extent to which infants exhibit these behaviors and how infants’ feeding cues and caregivers’ responses to these cues may co-develop over time.

Objectives

To describe age differences in the number and types of disengagement and satiation behaviors infants display during feeding, mothers’ feeding behaviors, and the correspondence between infants’ and mothers’ behaviors across the first year.

Methods

Mother-infant dyads (n = 227) were video-recorded during naturalistic bottle-feeding interactions in their homes when infants were age 1 mo, 2 mo, 4 mo, 6 mo, 9 mo, and 12 mo. Videos were coded using the Baby Behaviors when Satiated (BABES) coding scheme to assess relevant infant and mother behaviors.

Results

Infants exhibited a significantly greater variety of behaviors and total number of behaviors at 2 mo compared to 1 mo. Infant disengagement and satiation behaviors transitioned from behaviors characterized by decreased activity levels during early infancy to increased alertness, activity, and interest in surroundings during later infancy. Mothers also showed developmental shifts in behavior—moving from more direct involvement to increased verbal responses—with a decline in the total number of behaviors over time. Infants’ and mothers’ behavior rates were not significantly associated at 1 mo (r = ‒0.24, P = 0.061) or 2 mo (r = 0.15, P = 0.107), but were positively associated at 4 mo (r = 0.35, P < 0.001), 6 mo (r = 0.21, P = 0.008), 9 mo (r = 0.46, P < 0.001), and 12 mo (r = 0.26, P = 0.022).

Conclusions

Findings highlight age-related changes in infant communication of satiation and maternal responsiveness, as well as evidence that infants’ and mothers’ feeding behaviors co-develop and may become more aligned over time.
