项目摘要

PROJECT SUMMARY Making healthy food choices and eating in moderation during early childhood are central to obesity prevention and are thought to require effortful and goal-directed self-regulation. Appetite self-regulation (ASR) has been described as involving children’s use of eating-specific, “top-down” cognitive processes to moderate “bottom- up” biological drives to eat. Much of the research to date on ASR has focused on the role of bottom-up drives in shaping children’s behavioral susceptibility to obesity. Alternatively, little is known about the cognitive- developmental processes that shape children’s ability to make healthy food choices and eat in moderation during early childhood. Current perspectives hold that ASR is distinct from general self-regulation (e.g., executive functioning [EF]) among children, highlighting the large gap in scientific understanding of cognitive developmental influences on healthy eating and obesity prevention during the preschool years. The goal of this R21 exploratory investigation is to produce rigorous evidence of cognitive developmental influences on healthy eating behaviors (i.e., healthy food choices, eating in moderation) and weight status during preschool through the development of new measures of top-down ASR. Preschool is an important period for studying top-down ASR given the significant socialization of eating behaviors and rapid maturation of top-down regulatory processes that occur during this period. Participants will be 150 preschoolers (75 with normal weight, 75 with overweight or obesity) and their primary caregiver. Given well- documented socioeconomic disparities in self-regulation, diet quality, obesity among children, we will oversample families with low-income backgrounds. We will adapt existing measures of inhibitory, working memory, and attention shifting–core aspects of EF – to develop new measures of eating-specific, top-down ASR. ASR/EF associations with laboratory-based observations of children’s eating behaviors, body mass index z-scores, and questionnaire-based measures of food parenting will be assessed. Aim 1 will adapt well- established objective observational measures of top-down EF to assess top-down ASR regulation among preschoolers. Aim 2 will examine the protective role of top-down ASR in making healthful food choices, eating in moderation, and weight status among preschoolers. Given that parenting represents a socialization pathway that can hinder or facilitate self-regulation in children, Aim 3 will evaluate associations of food parenting structure and autonomy support with top-down ASR among children. Raising children to make healthy food choices and eat in moderation in the current obesogenic environment may require more explicit involvement of cognitive-developmental processes around eating than has been previously appreciated. The findings of this investigation will yield novel scientific directions for obesity prevention by elucidating cognitive developmental influences on healthy food choices, eating in moderation, and weight status among preschoolers.
项目摘要 在幼儿期选择健康的食物和适度饮食是预防肥胖的核心 并且被认为需要努力和目标导向的自我调节。食欲自我调节(ASR) 被描述为涉及儿童使用特定于饮食的、“自上而下”的认知过程来调节“自下而上” “吃”的生物驱动力。迄今为止,关于ASR的许多研究都集中在自下而上驱动力的作用上 在塑造儿童对肥胖的行为易感性方面。另一方面,人们对认知- 塑造儿童选择健康食物和适度饮食能力的发展过程 在童年早期。目前的观点认为,ASR不同于一般的自我调节(例如, 执行功能[EF]),突出了对认知功能的科学理解方面的巨大差距。 在学龄前阶段对健康饮食和肥胖预防的发展影响。的目标 这项R21探索性研究旨在提供认知发展的严格证据, 对健康饮食行为的影响(即,健康的食物选择,适度饮食)和体重 通过自上而下的ASR新措施的发展,在学前阶段的地位。学前教育是一个 考虑到饮食行为的显著社会化和快速发展, 在此期间发生的自上而下的监管过程的成熟。参与者将达到150人 学龄前儿童(75名体重正常,75名超重或肥胖)及其主要照顾者。如果条件好- 有记录的社会经济差异在自我调节,饮食质量,儿童肥胖,我们将 对低收入家庭进行过度抽样。我们将调整现有的抑制措施, 记忆和注意力转移-EF的核心方面-开发新的饮食特定的,自上而下的措施 ASR。ASR/EF与儿童饮食行为、体重指数的实验室观察的关联 将评估z分数和基于食物养育的测量。目标1将适应良好- 建立了自上而下的EF客观观察措施,以评估自上而下的ASR调节, 学龄前儿童目标2将研究自上而下的ASR在做出健康食物选择,饮食, 以及学龄前儿童的体重状况。鉴于养育子女代表着一种社会化途径 目标3将评估食物养育与儿童自我调节的关系, 结构和自主性支持与自上而下的ASR儿童。培养孩子做健康食品 在目前的肥胖环境中,选择和适度饮食可能需要更明确的参与, 认知发展过程中的饮食比以前已经认识到。这一发现 研究将通过阐明认知发展,为预防肥胖提供新的科学方向。 影响健康食品的选择,适度饮食,以及学龄前儿童的体重状况。
