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.

抽象的 该K23职业发展奖的候选人致力于作为独立资助的职业 临床和翻译的研究人员和小儿肥胖症领域的领导者。这个K23职业 发展奖将使候选人能够完成她的教育目标 结构方程建模，纵向研究设计和分析，饮食评估，观察到标准化 喂养和压力的度量。在所有这些活动中，她将被一个成就卓著的人所考虑的 多学科导师和顾问团队。她的导师在营养和 纵向评估（Mara Vitolins博士），生物统计学（Edward IP）和儿童肥胖症（约瑟夫博士 Skelton）。候选人还将利用一个杰出的咨询委员会，具有观察性专业知识 喂养研究（Julie Lumeng博士），体重感知（Eliana Perrin博士），《压力的生理测量》（博士 Patricia Nixon）和焦虑（Gretchen Brenes博士）。在她作为一般儿科医生的临床工作中，候选人 指出，许多父母对孩子的挑剔饮食表示担忧，无论他们的孩子正在吃饭 足够，或者他们的孩子是否体重不足。候选人的初步工作表明 担心会影响父母如何喂养子女，导致行为，例如压力饮食或过度喂食。 这些方法最终可能导致儿童压力增加，并改善自我调节 进食，进而增加肥胖和糖尿病的长期风险。但是，预测性 儿童与父母因素，喂养实践和肥胖之间的关系尚不清楚。另外， 先前尚未研究父母喂养实践与儿童压力之间的关系。到 解决知识中的这些差距，提出了以下具体目的：1）评估 父母对孩子的体重和饮食行为的担忧，饮食压力，进食频率和 数量和饮食品种； 2）评估父母喂养实践对儿童压力的影响，儿童自我 饮食和能量摄入的调节； 3）评估父母关注和父母喂养的影响 儿童体重（BMIZ）的实践。中心假设是父母对他们的关注 儿童的饮食和体重随后的饮食和体重更大：1）喂养频率和 数量; 2）吃压力； 3）进餐时间的压力； 4）体重状态（体重指数z得分 [BMIZ]）。为了调查这些目标，候选人将招募300名父母，分别为3至6岁的孩子 完成问卷和50个亲子二元组的子样本直接参与标准化 观察到的喂养（观察饮食和压力的压力）和饮食召回将超过2年。这 该研究建议的初步数据以及在整个职业发展计划中所获得的技能 将直接支持将来的R01应用程序，以扩展这项工作，以进行随机对照试验 确定有效的干预措施以改善喂养习惯并减少肥胖症。
