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K01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）获得小儿睡眠科学和测量的专业知识，以补充她的强大 营养和体育锻炼的培训，2）增加对儿童成长和发育的了解 与能源平衡有关，以及3）提高她在研究设计方面的技能以计划RCT。这个培训将 为她提供建立独立研究计划所需的技能。为了实现这些目标， 马丁内斯博士已经组建了一个具有相关专业知识的导师团队，以填补她的研究空白 经验。她的指导团队包括：罗纳德·达尔（Ronald Dahl）博士，在儿科睡眠方面具有专业知识；希拉博士 Gahagan，在儿童成长和成长方面具有专业知识； Jeanne Tschann博士，在拉丁裔家庭中拥有专业知识 在拉丁美洲家庭中特别是动态，研究实施，招聘和保留；南希·布特（Nancy Butte）博士， 小儿肥胖和代谢方面的专业知识；和Patricia Crawford博士，具有社区营养方面的专业知识 以及临床试验以及出色的指导记录。通过这个K01奖，马丁内斯博士将实现她 长期目标是成为一名独立研究者，进行有关如何进行能量平衡的研究 减少服务不足的拉丁裔儿童的慢性病。 墨西哥血统的个人占美国拉丁裔人口中最大的比例 他们的肥胖率很高。通过对潜在行为机制的了解的改进 短时间睡眠持续时间可能会影响墨西哥裔美国儿童的肥胖症对于预防和/或 减少该人群中的肥胖和慢性疾病。马丁内斯博士的研究将重点关注：行为 将睡眠持续时间与肥胖联系起来的机制（即饮食和身体活动）（AIM 1）。这些关系会 在墨西哥裔美国人8-10岁的现有数据集中进行检查（n = 323）。对于AIM 2和AIM 3，数据 将在墨西哥裔美国8-10岁的新样本中收集：1）上下文因素（即 就寝时间习惯，睡眠卫生，家庭主义）可能会影响睡眠（目标2）； 2）前一夜的影响 随后一天的饮食和体育锻炼持续时间（AIM 3）。这项研究将用于计划 随机控制干预措施以促进墨西哥人最佳睡眠，健康饮食和体育锻炼 美国儿童，将在K01颁奖典礼结束之前在R34赠款申请中提出。
