Previously, we demonstrated that infants' caloric compensation ability decreases between 11 and 15 months old. Here, we explored whether the inter-individual variation in infants' caloric compensation ability is associated with caregiver-infant interaction during laboratory test meals or with infant appetitive traits. To describe caregiver-infant interaction, we recorded feeding in laboratory ad libitum meals when the infants were 11 and 15 months old by using a connected weighing scale. We extracted the weight of each offered spoonful and the time interval between two spoonfuls. The caloric compensation score (COMPX) was assessed during the same meals. At 11 and 15 months old, the caregiver rated their infant's appetitive traits by completing the CEBQ-T. Student's t tests were applied to test the relationships between the variables describing the caregiver-infant interaction and the COMPX score. The relationships between the COMPX score or its change and the infants' appetitive traits were assessed with Kendall correlations. Regarding appetitive traits, the more the caloric compensation ability decreased between 11 and 15 months old, the more the infants were perceived as food responsive between these ages (τ = -0.36, p = 0.01, n = 28). At 11 months old, when the time interval between two spoonfuls was positively associated with the previous spoonful weight (i.e., a longer time interval after a larger spoonful weight), the infants exhibited a better caloric compensation ability (t = -2.1, p = 0.04, n = 38). Moreover, this study provides new evidence regarding the importance of a responsive feeding style by suggesting that adapting the feeding pace to the spoonful weight could be a favourable practice associated with better caloric compensation ability by the end of the first year.

先前，我们已经证明婴儿的热量补偿能力在 11 至 15 个月之间下降。在这里，我们探讨了婴儿热量补偿能力的个体间差异是否与实验室测试餐期间的照顾者-婴儿互动或婴儿的食欲特质有关。为了描述照顾者-婴儿的互动，我们在婴儿 11 至 15 个月时使用连接的称重秤记录了实验室自由进食期间的喂养情况。我们提取了每勺提供的重量和两勺之间的时间间隔。在同一餐中评估了热量补偿得分（COMPX）。在 11 至 15 个月时，照顾者通过完成 CEBQ-T 来评估其婴儿的食欲特质。应用学生 t 检验来检验描述照顾者-婴儿互动的变量与 COMPX 得分之间的关系。使用 Kendall 相关性评估 COMPX 得分或其变化与婴儿食欲特质之间的关系。关于食欲特质，11 至 15 个月之间热量补偿能力下降得越多，婴儿在这些年龄段被认为越对食物有反应（τ= -0.36，p= 0.01，n= 28）。在 11 个月时，当两勺之间的时间间隔与前一勺的重量呈正相关（即，较大的勺重后时间间隔较长）时，婴儿表现出更好的热量补偿能力（t= -2.1，p= 0.04，n= 38）。此外，本研究提供了关于响应式喂养方式重要性的新证据，表明根据勺重调整喂养速度可能是一种有利的做法，与第一年结束时更好的热量补偿能力相关。试验注册：该试验在 clinicals.gov 上注册为 NCT03409042（https://clinicaltrials.gov/ct2/show/NCT03409042）。
