DESCRIPTION (provided by applicant): Childhood obesity is considered one of the most serious health problems facing youth. It is generally agreed that parents, as the gatekeepers to food and primary role models for children play an important role in shaping child eating behaviors. Unfortunately, little longitudinal data are available that examine simultaneously the evolution of parental feeding practices and child eating behaviors. The Net-Works grant is an NICHD-funded study that will follow parent feeding practices and child eating behaviors over time in the context of a multi- setting intervention trial (e.g., primary care, parenting classes, n-home visitors) targeting obesity prevention in low income and ethnically diverse children (n=500) ages two to four years. The present research proposal, Sib- Works, is ancillary to the Net-Works study and has two main aims. The primary aim of Sib-Works is to examine parent feeding practices in response to sibling dyads' eating behaviors and to identify reciprocal processes between sibling dyads' eating behaviors and parent feeding behaviors. For example, (1) How similar (or different) are eating behaviors of sibling dyads?; (2) What feeding practices do parents use if sibling dyads differ in their eating behaviors or Body Mass Index z-score (BMIz)?; (3) Do parents' tailor feeding behaviors to individual children's eating behaviors, or do they use feeding behaviors that have been established with older siblings?; (4) How does parent response to differences between children's eating behaviors affect the family food environment and family eating patterns? (5) What is the temporal relationship between parent feeding practices, sibling dyad's eating behaviors and sibling dyad's BMIz? Prior research has not examined the eating behaviors of more than one child in the same home. Thus, the current study offers a unique opportunity to expand knowledge of family dynamics related to obesity risk development. The secondary aim of Sib-Works is to examine intervention spillover effects of the NET-Works intervention on siblings. While some family-based studies have shown intervention spillover effects for family members of index participants, spillover effects have not been identified for childhood obesity interventions specifically. The Sib-Works main aims will be answered by adding measures to the parent study including: parent feeding practices (e.g., encouragement to eat more or less) with a sibling, sibling eating behaviors (e.g., interest in food), and family eating patterns (e.g., family meals). Sibling (closet-aged older sibling; n=317) data collection will coincide with the parent study at 12-, 24-, and 36-months. Sib-Works will allow for the evaluation of a more complex interactive model of the dynamics between parents and multiple children within the home food environment in order to identify key modifiable variables and processes that could be targeted in family-based interventions to prevent childhood obesity. Additionally, identifying whether interventions have the potential to impact siblings not directly participating in an intervention will inform whether programs need to be tailored to different children within the home, or whether universal interventions are adequate, thus reducing costs.

描述(申请人提供)：儿童肥胖被认为是青少年面临的最严重的健康问题之一。人们普遍认为，父母作为食物的守门人和孩子的主要榜样，在塑造孩子的饮食行为方面发挥着重要作用。不幸的是，几乎没有纵向数据可以同时检查父母喂养习惯和儿童进食行为的演变。网络赠款是由NICHD资助的一项研究，将在一项旨在预防低收入和种族多样化的2至4岁儿童(n=500)肥胖的多环境干预试验(例如，初级保健、育儿班、家庭访客)的背景下，跟踪父母的喂养做法和儿童的进食行为。目前的研究方案SIB-Works是对网络研究的辅助，有两个主要目的。Sib-Works的主要目的是研究双亲对兄弟姐妹进食行为的反应，并确定兄弟双亲进食行为与双亲取食行为之间的相互作用过程。例如，(1)兄弟姐妹的进食行为有多相似(或不同)？(2)如果兄弟姐妹的进食行为或身体质量指数(BMIz)不同，父母会使用什么喂养方式？(3)父母的喂养行为是根据孩子的个别饮食行为量身定做的，还是使用与大一点的兄弟姐妹建立的喂养行为？(4)父母对子女饮食行为差异的反应如何影响家庭食物环境和家庭饮食模式？(5)父母的喂养方式、兄弟姐妹的饮食行为和兄弟姐妹的BMIz之间存在怎样的时间关系？之前的研究没有检查过同一个家庭中多个孩子的饮食行为。因此，目前的研究提供了一个独特的机会来扩大与肥胖风险发展相关的家庭动力学知识。SIB-Works的次要目标是检查网络干预对兄弟姐妹的干预溢出效应。虽然一些以家庭为基础的研究表明，干预对指数参与者的家庭成员有溢出效应，但尚未明确儿童肥胖干预的溢出效应。将通过在父母研究中增加措施来实现Sib-Works的主要目标，包括：父母与兄弟姐妹一起进食的做法(例如，鼓励多吃或少吃)、兄弟姐妹的饮食行为(例如，对食物的兴趣)以及家庭饮食模式(例如，家庭用餐)。兄弟姐妹(壁橱年龄较大的兄弟姐妹；n=317)数据收集将在12个月、24个月和36个月时与父母研究一致。SIB-Works将能够评估家庭食物环境中父母和多个孩子之间的动态的更复杂的互动模型，以便确定在以家庭为基础的干预措施中可以针对的关键可修改变量和过程，以防止儿童肥胖。此外，确定干预措施是否有可能影响没有直接参与干预的兄弟姐妹，将有助于了解是否需要为家庭中的不同儿童量身定做方案，或者普遍干预措施是否足够，从而降低成本。
