PROJECT SUMMARY/ABSTRACT Rapid weight gain during infancy has been recognized as a prime target for prevention and intervention efforts and formula-/bottle-feeding has been highlighted as one of the strongest modifiable predictors of risk for rapid weight gain during the postpartum period. Current recommendations and prevention programs aimed at reducing risk for rapid weight gain and obesity during early childhood have predominately focused on promoting responsive feeding practices, regardless of milk type or feeding mode used. However, previous research examining responsive feeding has taken a mother-centric approach, focusing on relating mothers' feeding practices and styles to infant outcomes without adequate consideration of how infant behaviors – such as ability to effectively communicate satiation – may influence feeding interactions. The study of dyadic interactions is common within the broader field of research on infant development, yet a marked paucity of research within the field of infant feeding attempts to objectively describe dyadic interactions during feeding to examine what both infants and mothers contribute to feeding interactions. The aim of the proposed research is to address this research gap by describing the co-development of infant communication of satiation and mothers' feeding practices across infancy and feeding contexts. The Co-Is are currently conducting the ABC Baby Study, an NICHD-funded (R01HD084163) prospective, longitudinal study of 325 mother-infant dyads assessed when infants were 2 weeks and 2, 4, 6, 9, and 12 months. The overall objective of the ABC Baby Study is to describe associations between developmental trajectories of infants' appetitive drives and weight gain. A unique feature of this study is that all dyads are video-recorded during naturalistic bottle-feeding interactions at each assessment and solid food feeding interactions at 6, 9, and 12 months. Yet, behavioral coding of the videos was not part of the parent grant aims. In the proposed study, we aim to add novel, objective measures of infant communication of satiation and maternal responsiveness to infant cues during feeding to allow for an innovative investigation that will inform future - and much needed – primary prevention efforts. By combining existing study data with the novel data collected in the proposed research, we will aim to: 1) describe the dyadic interactions that occur during feeding at 2 weeks, and 2, 4, 6, 9, and 12 months and identify clusters of dyads who show distinct developmental trajectories of dyadic feeding interactions across infancy; 2) examine associations between cluster membership and risk for rapid weight gain between birth and 12 months; and 3) identify maternal and infant correlates of cluster membership. Findings from the proposed research will highlight modifiable mechanisms underlying associations between maternal-infant risk factors and infant outcomes, which will inform efforts to design tailored prevention programs best-fit to the needs of high-risk dyads.

项目摘要/摘要 婴儿期在婴儿期的快速增加被认为是预防和干预工作的主要目标 公式 - 喂养被强调为快速风险的可修改预测指标之一 产后体重增加。目前的建议和预防计划 降低儿童早期体重增加和肥胖的风险主要集中在 无论使用哪种牛奶类型或喂食模式，都可以促进响应式喂养实践。但是，以前 研究响应式喂养的研究采用了母亲以母亲的方式，重点是与母亲联系 喂养婴儿的喂养实践和样式为婴儿的结果，而没有充分考虑婴儿的行为如何 作为有效交流满意度的能力 - 可能会影响喂养相互作用。二元研究 相互作用在婴儿发育的更广泛的研究领域很常见，但明显的很少 婴儿喂养领域内的研究试图在进食期间客观地描述二元相互作用 检查婴儿和母亲对喂养相互作用的贡献。 拟议研究的目的是通过描述婴儿的共同开发来解决这一研究差距 在婴儿期和喂养环境中的满意度和母亲的喂养实践的交流。共同是 目前正在进行ABC婴儿研究，一项由NICHD资助（R01HD084163）的前瞻性，纵向研究 在婴儿何时为2周和2周，4、6、9和12个月的325个母亲二元组中。 ABC婴儿研究的目的是描述婴儿的发育轨迹之间的关联 食欲驱动和体重增加。这项研究的一个独特功能是，所有二元组在视频中均录制 每次评估的自然主义奶瓶喂养相互作用和6、9和12的固体食品喂养相互作用 月份。但是，视频的行为编码并不是父母赠款目标的一部分。在拟议的研究中，我们 旨在增加婴儿满意度和母体反应能力的新颖，客观的衡量 喂养过程中的婴儿提示，以允许创新投资，以供未来和急需 - 主要预防工作。通过将现有研究数据与提议中收集的新数据相结合 研究，我们的目标是：1）描述在2周时进食期间发生的二元相互作用，2、4、6， 9和12个月，并确定二元组的簇，它们显示出不同的二元喂养发展轨迹 跨婴儿期的相互作用； 2）检查集群成员资格与重量快的风险之间的关联 在出生到12个月之间的出生； 3）确定集群成员的母亲和婴儿相关性。 拟议研究的发现将突出可修改的机制 孕产妇的危险因素和婴儿结果，这将为设计量身定制的预防措施提供努力 计划最适合高风险二元组的需求。
