DESCRIPTION (provided by applicant): The objective of the proposed research is to test hypotheses related to understanding how bottle-feeding influences mothers' infant feeding practices and young infants' short-term feeding behaviors. The proposed research aims to elucidate potential strategies for optimizing feeding during infancy, which is one of the earliest opportunities for primary prevention of the negative health outcomes associated with undesirable intake and weight gain patterns, such as obesity and type II diabetes. Previous researchers have proposed that bottle-feeding mothers feed in response to the amount of milk or formula in the bottle, rather than in response to infant hunger and fullness cues, leading to overfeeding, excessive weight gain, and heightened risk for obesity. Although plausible, the evidence underlying this hypothesis is observational, at best, and we are currently lacking experimental data that allow us to fully understand the impact of bottle usage on mothers' feeding practices and infant consumption. The first specific aim of this research is to test the hypothesis that infants will consume less formula when fed from opaque, weighted bottles (OWBs; which remove visual and weight clues related to the amount of formula in the bottle) compared to when fed from conventional clear bottles (CCBs). The second specific aim of this research is to test the hypothesis that mothers will use more responsive feeding practices when using OWBs compared to when using CCBs when feeding their infants. We propose a within-subject design to test our hypotheses. Mother-infant dyads will visit our laboratory on three separate occasions for feeding observations. All visits will occur at the same time of day and visit days will be separated by one day. The first visit will be an acclimation visit, where we wil video-record mothers while they feed their infants their typical formula from a CCB. During the second and third visits, we will video- record mothers as they feed their infants their typical formula from a CCB or OWB; bottle type will be counterbalanced across these two visit days. Mothers will be instructed to feed their infant as they normally would at home. Bottles will be weighed pre- and post-feeding to assess infant intake. Video-records will be later coded using the Parent-Child Interaction Feeding Scale from the Nursing Child Assessment. We hypothesize that during the OWB condition, infants will consume less formula and mothers will show greater sensitivity to infant cues when compared to the CCB condition. The proposed research will provide important preliminary data for larger-scale intervention efforts. Findings from this study could provide evidence for a novel approach to promoting responsive feeding practices in bottle-feeding mothers: modification of the feeding context to facilitate bottle-feeding mothers' ability o attend to satiation cues displayed by their infants.

描述（由申请人提供）：拟议研究的目的是检验与了解奶瓶喂养如何影响母亲的婴儿喂养实践和幼儿的短期喂养行为有关的假设。拟议的研究旨在阐明优化婴儿期喂养的潜在策略，这是一级预防与不良摄入和体重增加模式相关的负面健康结果的最早机会之一，如肥胖和II型糖尿病。 以前的研究人员提出，奶瓶喂养的母亲根据奶瓶中的牛奶或配方奶的数量喂养，而不是根据婴儿的饥饿和饱足感，导致过度喂养，体重过度增加，肥胖风险增加。虽然这一假设似乎是合理的，但其背后的证据充其量只是观察性的，我们目前缺乏实验数据，无法充分了解奶瓶使用对母亲喂养方式和婴儿消费的影响。这项研究的第一个具体目的是检验这样一个假设，即与传统的透明奶瓶（CCB）相比，婴儿从不透明的加重奶瓶（OWB;它消除了与奶瓶中配方奶粉数量相关的视觉和重量线索）中喂养时，会消耗更少的配方奶粉。本研究的第二个具体目的是检验这一假设，即母亲在喂养婴儿时使用OWB时，与使用CCB时相比，会使用更敏感的喂养方法。 我们提出了一个主题内的设计来测试我们的假设。母婴配对将在三个不同的场合访问我们的实验室进行喂养观察。所有访视将在一天中的同一时间进行，访视日将间隔一天。第一次访问将是一个适应访问，我们将视频记录的母亲，而他们喂养他们的婴儿他们的典型配方从CCB。在第二次和第三次访视期间，我们将对母亲从CCB或OWB喂养婴儿的典型配方奶粉进行视频记录;在这两个访视日，将对奶瓶类型进行平衡。母亲们将被指示像在家里一样喂养婴儿。将在喂养前和喂养后对奶瓶进行称重，以评估婴儿摄入量。随后将使用哺乳儿童评估中的亲子互动喂养量表对视频记录进行编码。我们假设，与CCB条件相比，在OWB条件下，婴儿消耗的配方奶粉会更少，母亲对婴儿暗示会表现出更大的敏感性。 拟议的研究将为更大规模的干预工作提供重要的初步数据。这项研究的结果可以提供一种新的方法来促进奶瓶喂养母亲的反应性喂养实践的证据：喂养环境的修改，以促进奶瓶喂养的母亲的能力，以照顾他们的婴儿显示的饱足线索。
