ABSTRACT The candidate for this K23 career development award is committed to a career as an independently funded clinical and translational researcher and leader in the field of pediatric obesity prevention. This K23 Career Development Award will allow the Candidate to complete her educational goals of gaining experience in structural equation modeling, longitudinal study design and analysis, diet assessment, observed standardized feedings, and measures of stress. In all these activities, she will be mentored by a highly accomplished, multidisciplinary team of mentors and advisors. Her mentors have complementary expertise in nutrition and longitudinal assessment (Dr. Mara Vitolins), biostatistics (Dr. Edward Ip), and childhood obesity (Dr. Joseph Skelton). The Candidate will also utilize an outstanding advisory committee with expertise in observational feeding studies (Dr. Julie Lumeng), weight perception (Dr. Eliana Perrin), physiologic measures of stress (Dr. Patricia Nixon), and anxiety (Dr. Gretchen Brenes). In her clinical work as a general pediatrician, the candidate noted that many parents express concerns about their young child’s picky eating, whether their child is eating enough, or whether their child is underweight. The candidate’s preliminary work has demonstrated that such concerns affect how parents feed their children, leading to behaviors such as pressuring to eat or overfeeding. These approaches could ultimately lead to increased child stress at mealtimes and decreased self-regulation of eating, which in turn can increase long-term risk of obesity and diabetes. However, the predictive relationships between child and parent factors, feeding practices, and obesity remain unclear. Additionally, the relationship between parent feeding practices and child stress has not been previously investigated. To address these gaps in knowledge, the following Specific Aims are proposed: 1) to assess the effects of parental concerns about their child’s weight and eating behaviors on pressure to eat, feeding frequency and amount, and dietary variety; 2) to assess the effects of parent feeding practices on child stress, child self- regulation of eating, and energy intake; and 3) assess the effect of parent concerns and parent feeding practices on child body weight (BMIz). The central hypotheses are that parental concerns about their child’s eating and weight are associated with children’s subsequent greater: 1) feeding frequency and amount; 2) pressure to eat; 3) stress at mealtimes; and 4) body weight status (body mass index z-score [BMIz]). To investigate these aims the Candidate will recruit a cohort of 300 parents of 3- to 6-year-old children to complete questionnaires and a subsample of 50 parent-child dyads to participate in standardized directly observed feedings (observing pressure to eat and stress) and dietary recalls to follow over 2 years. The preliminary data from this research proposal and the skills achieved throughout the career development plan will directly support future R01 applications to expand this work to conduct randomized controlled trials to determine effective interventions to improve feeding practices and reduce obesity.

摘要 这个K23职业发展奖的候选人致力于作为一个独立资助的职业 临床和转化研究员，儿童肥胖预防领域的领导者。K23职业生涯 发展奖将允许候选人完成她的教育目标，获得经验， 结构方程模型，纵向研究设计与分析，饮食评估，观察标准化 喂食和压力测量在所有这些活动中，她将由一位非常有成就的， 多学科的导师和顾问团队。她的导师在营养学方面有互补的专业知识， 纵向评估（Mara Vitolins博士）、生物统计学（Edward Ip博士）和儿童肥胖（Joseph博士 克莱顿）。候选人还将利用一个杰出的咨询委员会， 喂养研究（Julie Lumeng博士），体重感知（Eliana Perrin博士），压力的生理测量（Dr. 帕特里夏尼克松）和焦虑（格雷琴布雷尼斯博士）。作为一名普通儿科医生， 注意到许多父母对他们年幼的孩子挑食表示担忧，他们的孩子是否吃 #21453;，或者说，他们的孩子是不是太胖了。候选人的初步工作表明， 担心会影响父母喂养孩子的方式，导致诸如强迫进食或过度喂养等行为。 这些方法最终会导致儿童在进餐时的压力增加和自我调节能力下降 这反过来又会增加肥胖和糖尿病的长期风险。然而，预测 儿童和父母因素、喂养习惯和肥胖之间的关系仍不清楚。另夕h 父母喂养习惯和儿童压力之间的关系以前没有调查过。到 为了解决这些知识差距，提出了以下具体目标：1）评估 父母对孩子体重和饮食行为的担忧与进食压力、喂养频率和 量和饮食种类; 2）评估父母喂养方式对儿童压力，儿童自我， 饮食和能量摄入的调节;以及3）评估父母关注和父母喂养的影响 儿童体重（BMIz）。核心假设是，父母对他们的担忧 儿童的饮食和体重与儿童随后的更大的：1）喂养频率， 量; 2）进食压力; 3）进餐时的压力;以及4）体重状况（体重指数z评分 [BMIz]）。为了调查这些目标，候选人将招募300名3至6岁儿童的父母 完成问卷调查，子样本50名亲子配对直接参与标准化的 观察喂养（观察进食压力和压力）和饮食回忆，随访2年。的 本研究建议的初步数据和整个职业发展计划中获得的技能 将直接支持未来的R 01应用，以扩展这项工作，进行随机对照试验， 确定有效的干预措施，以改善喂养方式和减少肥胖。
