PROJECT ABSTRACT The proposed K01 award will provide Dr. Martinez with the support necessary to achieve her immediate training goals: 1) to gain expertise in pediatric sleep science and measurement to complement her strong training in nutrition and physical activity, 2) to increase understanding of child growth and development as it relates to energy balance, and 3) to advance her skills in research design to plan an RCT. This training will provide her with the skills necessary to establish her independent research program. To achieve these goals, Dr. Martinez has assembled a team of mentors with relevant expertise to fill the gaps of her research experience. Her mentoring team includes: Dr. Ronald Dahl, with expertise in pediatric sleep; Dr. Sheila Gahagan, with expertise in child growth and development; Dr. Jeanne Tschann, with expertise in Latino family dynamics, study implementation, recruitment and retention specifically in Latino families; Dr. Nancy Butte, with expertise in pediatric obesity and metabolism; and Dr. Patricia Crawford, with expertise in community nutrition and clinical trials and a track record of excellent mentorship. With this K01 award, Dr. Martinez will achieve her long-term goal to become an independent investigator conducting energy-balance related research on how to reduce chronic disease in underserved Latino children. Individuals of Mexican descent comprise the largest proportion of the Latino population in the United States and they suffer high rates of obesity. An improved understanding of the underlying behavioral mechanisms by which short sleep duration may impact obesity among Mexican American children is critical to prevent and/or reduce obesity and chronic disease in this population. Dr. Martinez's research will focus on: behavioral mechanisms (i.e., diet and physical activity) that link sleep duration to obesity (Aim 1). These relationships will be examined in an existing data set of Mexican American 8-10-year-olds (n=323). For Aim 2 and Aim 3, data will be collected in a new sample of Mexican American 8-10-year-olds to examine: 1) contextual factors (i.e., bedtime routines, sleep hygiene, familism) that may impact sleep (Aim 2); and 2) the impact of prior night's sleep duration on diet and physical activity the subsequent day (Aim 3). This research will be used to plan a randomized control intervention to promote optimal sleep, healthy eating and physical activity among Mexican American children, to be proposed in a R34 grant application before the end of the K01 award.

项目摘要 拟议的K 01奖将为马丁内斯博士提供必要的支持，以实现她的立即 培训目标：1）获得儿科睡眠科学和测量方面的专业知识，以补充她的强大 营养和体育活动方面的培训，2）增加对儿童生长和发育的了解， 与能量平衡有关，3）提高她在研究设计方面的技能，以规划RCT。本次培训将 为她提供必要的技能，以建立她的独立研究计划。为了实现这些目标， 博士马丁内斯已经组建了一个具有相关专业知识的导师团队，以填补她研究的空白 体验.她的指导团队包括：罗纳德达尔博士，具有儿科睡眠方面的专业知识;希拉博士 Gahagan，具有儿童成长和发展方面的专业知识; Jeanne Tschann博士，具有拉丁美洲家庭方面的专业知识 动态，研究实施，招聘和保留，特别是在拉丁美洲家庭;南希布特博士，与 儿科肥胖和代谢方面的专业知识;帕特里夏克劳福德博士，具有社区营养方面的专业知识 临床试验和优秀的指导记录。有了这个K 01奖，马丁内斯博士将实现她 长期目标是成为一名独立的调查员，进行能量平衡相关的研究，研究如何 减少服务不足的拉丁裔儿童的慢性病。 墨西哥裔人在美国拉丁裔人口中所占比例最大 他们的肥胖率很高。通过以下方式提高对潜在行为机制的理解 睡眠时间短可能会影响墨西哥裔美国儿童的肥胖，这对预防和/或 减少这一人群的肥胖和慢性病。马丁内斯博士的研究将集中在：行为 机构（即，饮食和身体活动），将睡眠时间与肥胖联系起来（目标1）。这些关系将 在墨西哥裔美国人8-10岁的现有数据集（n=323）进行检查。对于目标2和目标3，数据 将在一个新的墨西哥裔美国人8-10岁的样本中收集，以检查：1）背景因素（即， 睡前习惯，睡眠卫生，家庭主义）可能影响睡眠（目标2）;和2）前一天晚上的影响 第二天饮食和体力活动的睡眠持续时间（目标3）。这项研究将用于规划一个 随机对照干预，以促进墨西哥人的最佳睡眠，健康饮食和体育活动 美国儿童，在K 01奖结束前提出R34赠款申请。
