 DESCRIPTION (provided by applicant): This career development proposal will provide a promising early-career researcher, Dr. Sean C. Lucan, with the additional knowledge, tools, and skills needed to become an independent investigator. Dr. Lucan's interest is in how local food environments influence adolescent diet and diet-related health. Dr. Lucan will participate in a variety of training activities and apply lessons directly to an innovative patient-oriented researc project. The project will link dietary data from adolescent patients to data on food sources in the areas around which they live and attend school. The proposed training and research will facilitate transition from supervised study to independent investigation, culminating in the submission of R01 applications that address problems like incident obesity and diabetes for young people transitioning to adulthood. Dr. Lucan and a team of committed mentors and advisers designed a research-and-training plan to address limitations in both the existing scientific literature and in Dr. Lucan's own skill set. Regarding the existing scientific literatur, research suggests that areas around adolescents' homes and schools-most notably in low-income and minority communities-tend to offer predominantly fast foods, processed foods, and other less-healthy convenience items, with few healthy alternatives; such environments are generally associated with poorer diets and poorer health. However, many studies suggesting associations have been limited in several important ways. As a result, it is not clear how to intervene to change environments to make healthier eating an easier option (or an option at all) and unhealthy eating more difficult (or not the only option) for adolescents. The proposed project will build on prior work and be innovative in several important ways. It will rely on adolescent research assistants and geographic information science (GISc) to directly assess a full range of food sources within walking distance of adolescents' schools and homes. The research will assess links between food sources and dietary intake for adolescent patients, capitalizing on a unique health-system dataset: an electronic medical record (EMR) that contains both clinical and survey data. The specific aims are: Aim 1. To conduct a comprehensive assessment of local food sources: Adolescents will assess locations and food offerings for a full range of food sources to which they are exposed around their homes and schools. Aim 2. To generate a novel integrated multi-level database. Dr. Lucan will merge food-source data (from Aim 1) with other local data and with data on individual adolescent patients (from the health-system EMR) Aim 3. To assess how local food sources relate to adolescents' dietary intake. Dr. Lucan will use the database (from Aim 2), to assess how food sources around adolescents' homes and schools relate to their reported dietary intake (e.g., fruit, vegetable, and sugary-drink consumption). Analyses in this K23 work will be cross-sectional but the methods, database, and training will directly lay the foundation for longitudinal study (e.g., how changes i local food environments relate to changes in diet-related health outcomes like incident obesity, diabetes, dyslipidemia, and hypertension-all possible through the clinical data available in the EMR). Longitudinal studies will inform intervention trials that Dr. Lucan can submit as R01 applications towards informing policy changes and improving food environments, diet, and health. Regarding Dr. Lucan's own current skill set, he has identified one major areas of focus for coursework and mentored study (GISc) and three supporting areas (encrypted data management, statistical analyses, and behavioral and social science) that he will need to conduct the type of research that will move the field and his career forward. Dr. Lucan will enroll in a formal certificate program in GISc, and take courses in secure-data handling, multilevel modeling, behavioral and social-science theory. These learning activities, along with mentored study under expert mentors, will find practical application in the proposed research: GISc to define 'exposures' to local food sources, data management to link diverse datasets, behavioral and social-science theory to inform multilevel analyses, and regression modeling and GISc to analyze associations. The research and training activities will produce a confident patient-oriented researcher with the skills to conduct studies involving sensitive, multilevel, diverse, spatial data. Training will occur in a superlative research and learning environment. Both the institution and department rank highly in NIH funding and there are exceptional resources, facilities, personnel, partnerships, and expertise to support Dr. Lucan's project and training needs. There is experience with multilevel GISc considerations in patient-oriented research and tremendous expertise in behavioral and social sciences, nutrition studies, and research involving adolescents. Veteran supervising faculty has wide-ranging current and historical ties to NICHD. The proposed work will provide Dr. Lucan the training and the practical experience to support a career as an independent investigator.

 描述（由适用提供）：该职业发展建议将为早期研究员Sean C. Lucan博士提供额外的知识，工具和技能，以成为独立研究员。卢坎博士对当地食品环境如何影响青少年饮食和与饮食有关的健康的兴趣。 Lucan博士将参加各种培训活动，并将课程直接应用于创新的以患者为导向的研究项目。该项目将将青少年患者的饮食数据与有关食物来源的数据联系起来 他们居住和上学的地区。拟议的培训和研究将有助于从监督研究到独立调查的过渡，最终提交R01申请，这些申请解决了诸如肥胖事件和年轻人过渡到成年的问题之类的问题。 Lucan博士和一支由指导者和顾问组成的团队设计了一项研究和培训计划，以解决现有科学文献和Lucan博士自己的技能集中的局限性。关于现有的科学文献，研究表明，在低收入和少数民族社区中，青少年家园和学校周围的地区往往提供主要的快餐，加工食品和其他不太健康的便利性，几乎没有健康的替代品；这种环境通常与饮食较差和健康状况较差有关。但是，许多研究表明，关联的限制受到多种重要方式。结果，尚不清楚如何进行干预以改变环境以使更健康的饮食成为一个更容易的选择（或根本选择），而不健康的饮食更加困难（或不是唯一的选择）。拟议的项目将以先前的工作为基础，并以几种重要的方式创新。它将依靠青少年研究助理和地理信息科学（GISC）直接评估青少年学校和家庭的步行范围内的全部食物来源。该研究将评估青少年患者的食物来源与饮食摄入之间的联系，利用独特的健康系统数据集：一个包含临床和调查数据的电子病历（EMR）。具体目的是：目标1。对当地食物来源进行全面评估：青少年将评估他们在房屋和学校周围暴露的各种食物来源的位置和食物。目标2。生成一个新颖的集成多级数据库。 Lucan博士将将食品源数据（来自AIM 1）与其他本地数据合并，并与单个青少年患者（来自健康系统EMR）的数据相关。 Lucan博士将使用数据库（来自AIM 2）来评估青少年家园和学校周围的食物来源与报道的饮食摄入量有关（例如，水果，蔬菜和 含糖消耗）。这项K23工作的分析将是横断面的，但是方法，数据库和培训将直接为纵向研究奠定基础（例如，与饮食相关的健康结果的变化有关的变化与饮食相关的健康状况的变化有关，例如肥胖，糖尿病，血脂异常，血脂异常和高血压 - 通过临床数据可用）。纵向研究将为干预试验提供通知，卢坎博士可以作为R01的申请提交，以告知政策变化并改善食品环境，饮食和健康。关于Lucan博士自己目前的技能，他确定了课程和修改研究（GISC）和三个支持领域（加密的数据管理，统计分析以及行为和社会科学）的重点领域，他将需要进行研究的类型，以使该领域及其职业发展。注册 在GISC的正式证书计划中，并在安全数据处理，多层次建模，行为和社会科学理论中学习课程。这些学习活动以及专家指导者的指导研究将在拟议的研究中找到实际应用：GISC将“接触”定义为本地食品来源，数据管理，以将潜水员数据集链接，行为和社会科学理论联系起来，以告知多层分析以及回归模型和GISC，以分析关联。研究和培训活动将产生一个充满信心的以患者为导向的研究人员，其技能涉及敏感，多级，潜水员，空间数据。培训将在最高级的研究和学习环境中进行。该机构和部门在NIH资金方面都高度排名，并且有非凡的资源，设施，人员，合作伙伴和专业知识，以支持Lucan博士的项目和培训需求。有多级GISC考虑的经验在以患者为导向的研究以及行为和社会科学，营养研究以及涉及青少年的研究方面的巨大专业知识。资深监督教师与NICHD有广泛的当前和历史联系。拟议的工作将为Lucan博士提供培训和实践经验，以支持作为独立调查员的职业。
