 DESCRIPTION (provided by applicant): Childhood obesity is a significant public health problem with 17% of US children being overweight or obese. Once established, obesity tracks into later childhood and adulthood. Parents are vital in shaping child eating behavior, dietary intake, and ultimately obesity risk. Research implicates family mealtimes as important for child obesity prevention and development of healthy eating habits, but findings are not consistent. One reason for the inconsistent associations may be that a substantial proportion of parent-child interactions around food occur outside the mealtime context and have historically been unmeasured. Eating outside of mealtimes, particularly snacking after school hours has increased in recent years and is proposed as contributing to excessive child weight gain and a potentially important context for child socialization around food and eating. Yet, little is known about: 1) naturalistic parent-child interactions around food (i.e., "food parenting") outside of mealtimes; 2) how child factors (e.g., persistence in requesting snacks) may contribute; or 3) how food interactions outside of mealtimes vary across development. Understanding food talk outside of mealtimes holds promise for future intervention development to prevent childhood obesity. The proposed work would also fill a critical methodological gap, as extant studies rely on parents' self-reported feeding, observed structured laboratory interactions, or family mealtimes. No prior study has observed parent-child food talk between meals in relation to child obesity risk. Leveraging an ongoing cross-sectional study, we propose to analyze naturalistic parent-child interactions around food and eating during after school hours in relation to detailed, multi-method assessments of child eating behavior, dietary intake, and parent feeding style, family mealtime interactions, and child adiposity. We will use discourse-analysis and behavioral-coding approaches to assess the process and content of naturally occurring parent and child talk about food and eating based on audio recordings using the Language Environment Analysis (LENA) system. Our team has pioneered use of this system to study parenting and is uniquely expert in assessing food parenting and child eating behavior. Our aims are, in families with children ages 12-24 months (n=40), 3-5 years (n=40), and 10-13 years (n=60): Aim 1. To assess frequency, discourse features, and emotional tone of naturalistic parent-child interactions involving food or eating outside of mealtime ("food talk"), and whether these differ by age. Aim 2. To assess whether food talk is associated with parent-reported child eating behaviors and child dietary intake. Aim 3. To assess whether food talk is associated with parent-reported feeding styles and observed family mealtime interactions. Aim 4. To assess whether food talk is associated with child adiposity indicators (BMIz, skinfolds, and weight status) and with rate of change in BMIz across a six-month period.

 描述（由适用提供）：儿童肥胖是一个重大的公共卫生问题，其中17％的美国儿童超重或肥胖。一旦建立，肥胖就可以追溯到幼儿和成年。父母对于塑造儿童饮食行为，饮食摄入量和最终肥胖风险至关重要。研究将家庭用餐对预防儿童肥胖和健康饮食习惯的发展很重要，但发现并不一致。不一致的关联的原因之一可能是，围绕食物的亲子相互作用发生在进餐时间之外，并且历史上没有得到衡量。近年来，在进餐时间以外的时间，尤其是零食，并提议导致儿童体重增加过多，并且是对食物和饮食周围儿童社交的潜在重要背景。然而，关于以下几个以下食物（即“食物育儿”）在进餐时间之外的食物（即“食物育儿”）的自然主义亲子互动知之甚少； 2）儿童因素（例如，请求小吃的持久性）如何贡献；或3）进餐时间以外的食物相互作用在开发过程中如何变化。在进餐时间之外了解食物谈话有望将来的干预开发以防止儿童对象。拟议的工作还将填补关键的方法论差距，因为现有的研究依赖于父母的自我报告的喂养，观察到的结构化实验室相互作用或家庭用餐时间。没有先前的研究观察到与儿童拥有风险有关的餐点之间的亲子食物谈话。利用正在进行的横截面研究，我们建议分析自然主义的亲子互动，围绕食物和放学后的饮食，以与细节有关 多方法评估儿童饮食行为，饮食摄入量以及家长喂养风格，家庭进餐时间互动和儿童肥胖。我们将使用话语分析和行为编码方法来评估使用语言环境分析（LENA）系统根据录音（LENA）系统的录音的父母和饮食的自然发生的过程和内容。我们的团队率先利用该系统来研究育儿，并且是评估食物育儿和儿童饮食行为的独特专家。我们的目的是，在有12-24个月的儿童（n = 40），3-5岁（n = 40）和10-13岁（n = 60）的家庭中：旨在评估涉及食物或饮食时间以外的食物的频率，话语特征和情感语气（“食物谈话”）（“食物谈话”），以及这些与年龄不同。目标2。评估食物谈话是否与父母报告的儿童饮食行为和儿童饮食摄入有关。目标3。评估食物谈话是否与父母报告的喂养方式和观察到的家庭用餐时间相互作用有关。目的4。评估食物谈话是否与儿童肥胖指标（BMIZ，皮肤折叠和体重状况）以及六个月内BMIZ的变化率有关。
