项目摘要

PROJECT SUMMARY/ABSTRACT Rapid weight gain during infancy is an important target for obesity prevention 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, the evidence-base for how to promote responsive feeding during bottle-feeding is scant, primarily due to methodological limitations of previous research. Within-subject studies that allow for examination of mothers' feeding practices during both breast and bottle-feeding are needed to elucidate the most effective targets for tailored primary prevention efforts. The aim of the proposed research is to address current research gaps by conducting a within-subject, laboratory-based experimental study of 40 mother-infant dyads wherein we will observe dyads during both bottle- and breastfeeding interactions. Strengths of this approach will be the ability to: 1) isolate effects of feeding mode on feeding outcomes; 2) consider how individual differences in maternal sensitivity to infant cues moderates effects of feeding mode on feeding outcomes; and 3) control for unmeasured covariates that may influence both feeding decisions and practices. To this end, we will objectively assess infant intake during these two modes of feeding by weighing the baby before and after the feeding. We will also video-record feeding observations to allow for behavioral coding of maternal sensitivity to infant cues and infant clarity of cues using the Nursing Child Assessment Parent-Child Interaction Feeding Scale (NCAFS), and will place electrocardiogram (ECG) leads on both mothers and infants to assess behavioral and physiological synchrony during feeding interactions. These data will be used to address the following specific aims: Aim 1: To examine whether maternal sensitivity to infant cues moderates effects of feeding mode on infant intake; Aim 2: To identify key predictors of low maternal sensitivity to infant cues; Exploratory Aim: To examine whether maternal-infant behavioral and physiological synchrony differs between bottle-feeding versus breastfeeding. This innovative study will provide novel insights related to how feeding mode and mothers' feeding practices interact to influence infant feeding outcomes and will create an important foundation for further research related to the primary prevention of obesity during early infancy.

项目摘要/摘要婴儿期间的快速体重增加是预防肥胖症和配方/瓶的重要目标喂养已被强调为最强的修改性预测指标之一，即在产后期。目前的建议和预防计划旨在降低快速的风险幼儿期的体重增加和肥胖主要集中于促进反应式喂养实践，无论使用牛奶类型或喂食模式如何。但是，如何促进的证据基础奶瓶喂养期间的响应式进食很少，这主要是由于以前的方法论限制研究。受试者内的研究允许在两个乳房期间检查母亲的喂养做法需要进行奶瓶喂养，以阐明量身定制的初级预防工作的最有效目标。拟议的研究的目的是通过进行主体内部的，基于实验室的40个母亲二元组的实验研究，其中我们将在这两个过程中观察到二元组瓶和母乳喂养的互动。这种方法的优势将是：1）喂养结果的进食模式； 2）考虑母体对婴儿提示的敏感性的个体差异喂养模式对喂养结果的调节作用； 3）控制未测量的协变量影响喂养决策和实践。为此，我们将客观地评估婴儿的摄入量这两种喂养模式通过在喂养之前和之后称重婴儿。我们还将视频记录进食观察以允许对婴儿提示的行为编码对婴儿提示的敏感性和婴儿的清晰度使用护理儿童评估的提示亲子互动量表（NCAF），并将放置心电图（ECG）导致母亲和婴儿都评估行为和生理同步在喂养相互作用期间。这些数据将用于解决以下特定目的：目标1：检查孕产妇对婴儿提示的敏感性是否会调节喂养模式对婴儿摄入的影响；目标2：到确定对婴儿提示低母体敏感性的关键预测指标；探索目的：检查是否饲养瓶喂养与母乳喂养之间的行为和生理同步不同。这项创新的研究将提供与喂养模式和母亲的喂养实践有关的新颖见解互动以影响婴儿喂养结果，并将为进一步研究创造重要的基础与婴儿早期肥胖的主要预防有关。
