项目摘要
PROJECT SUMMARY
Emerging evidence suggests that infants with greater appetitive drive may benefit from different feeding
approaches for the prevention of obesity and chronic disease. Slower milk delivery may be a promising
strategy, given that slower eating is associated with reduced intake and lesser weight gain throughout the
lifespan, including in infancy. In a sample of 243 infants aged 2-4 months, slower milk delivery increased
sucking effort and reduced intake. The results of this experiment, though reflective of only a single pair of
feedings, suggest that slower milk delivery may be a promising intervention strategy for addressing excessive
infant weight gain. However, many questions remain before the development of such an intervention could be
pursued, including the mechanism for this behavior change. The proposed project will examine infant, mother,
and dyadic interaction behavior during the feedings with slower milk delivery from this experiment, and
compare infant, mother, and dyadic behavior between faster and slower milk delivery to address the following
aims. Aim 1 (K99): To examine the relative contributions of infant (satiation signaling, behavioral distress,
sucking vigor), maternal (responsivity, behavioral distress), and dyadic (mutuality, feeding duration) behaviors
as mechanisms explaining the effect of slowed milk delivery on reduced intake in a single feeding. Aim 2
(K99): To examine whether the pathways of association in this conceptual model differ between infants with
typical versus high appetitive drive. Aim 3 (R00): Among 220 infants at age 8-12 weeks, to examine—across
72 hours of feedings in which milk delivery rate is slowed by 30% compared to typical—the cross-lagged
associations of changes from baseline in sucking vigor and feeding frequency with infant satiation signaling,
infant behavioral distress, and dyadic mutuality and to determine if these associations differ based on higher
versus lower infant appetitive drive. The PI, Dr. Crandall, is a behavioral scientist with an interdisciplinary
background in nutrition, psychology, and public health. Her growing research program seeks to understand
the cascading effect of high infant appetitive drive, integrating the dyadic nature of infant eating/feeding with
the hope of developing safe, effective, and equitable intervention strategies. With the support of a
multidisciplinary team of mentors, during the training phase of this award Dr. Crandall will grow her content
knowledge of the physiology of infant eating behavior and growth; gain experience with three levels of
behavioral coding of mother-infant feeding interactions; gain experience with structural equation modeling
techniques; and, in the R00 phase, conduct an independent investigation of infant/mother feeding behavior
with slower milk delivery across multiple days. At the conclusion of the award period, Dr. Crandall will be
poised to test an intervention designed to manage high appetitive drive and excessive intake, among infants
most at risk, while promoting maternal and infant well-being and the health of the dyadic interaction.
项目摘要
新出现的证据表明,具有更大食欲的婴儿可能受益于不同的喂养方式。
预防肥胖和慢性病的方法。更慢的牛奶输送可能是一个有希望的
策略,考虑到缓慢进食与整个过程中摄入量减少和体重增加减少有关,
包括婴儿期。在243名2-4个月大的婴儿样本中,
吸吮努力和减少摄入量。这个实验的结果,虽然只反映了一对
喂养,表明较慢的牛奶交付可能是一个有前途的干预策略,以解决过度
婴儿体重增加。然而,在制定这种干预措施之前,仍有许多问题有待解决。
包括这种行为改变的机制。拟议的项目将审查婴儿,母亲,
和来自该实验的在具有较慢的乳汁输送的喂养期间的二元相互作用行为,以及
比较婴儿、母亲和婴儿在快速和慢速输奶之间的行为,以解决以下问题
目标。目的1(K99):检查婴儿的相对贡献(饱足信号,行为困扰,
吮吸活力)、母性(反应性、行为痛苦)和二元(相互性、喂养持续时间)行为
作为机制,解释了在单次喂养中牛奶输送减慢对摄入量减少的影响。目的2
(K99):为了检查在这个概念模型中,婴儿与婴儿之间的联系途径是否不同,
典型的和高欲望的驱动力。目标3(R 00):在220名8-12周龄婴儿中,检查
72小时的喂养,与典型的交叉滞后相比,牛奶输送速度减慢了30%。
吸吮活力和喂养频率与婴儿饱足信号的基线变化的相关性,
婴儿行为困扰,和二元相互性,并确定这些协会是否不同的基础上更高
与低婴儿食欲驱动力的对比。私家侦探克兰德尔博士是个行为科学家
有营养学、心理学和公共卫生的背景。她不断发展的研究项目旨在了解
高婴儿食欲驱动的级联效应,将婴儿进食/喂养的二元性质与
希望制定安全、有效和公平的干预策略。并辅之以有效的
多学科的导师团队,在这个奖项的培训阶段,克兰德尔博士将增加她的内容
了解婴儿饮食行为和生长的生理学知识;获得三个层次的经验,
母婴喂养相互作用的行为编码;通过结构方程建模获得经验
技术;在R 00阶段,对婴儿/母亲喂养行为进行独立调查
在多天内牛奶输送较慢。在奖励期结束时,克兰德尔博士将
准备测试一项旨在控制婴儿高食欲和过量摄入的干预措施,
最危险的人群,同时促进母婴福祉和二元互动的健康。
