 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（由申请人提供）：该职业发展提案将为一位有前途的早期职业研究员 Sean C. Lucan 博士提供成为一名独立研究者所需的额外知识、工具和技能。 Lucan 博士的兴趣在于如何进行研究。当地的食物环境影响青少年的饮食和饮食相关的健康。卢坎博士将参加各种培训活动，并将经验教训直接应用到一个以患者为导向的创新研究项目中，该项目将把青少年患者的饮食数据与食物来源数据联系起来。在 拟议的培训和研究将促进从监督研究向独立调查的转变，最终提交 R01 申请，解决青少年过渡到成年后发生的肥胖和糖尿病等问题。一个由忠诚的导师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卢坎博士自己的技能方面的局限性。关于现有科学文献，研究表明青少年家庭和学校周围的区域 -最多在低收入和少数族裔社区中尤为明显——往往主要提供快餐、加工食品和其他不太健康的便利食品，而很少有健康的替代品；然而，许多研究表明，这种环境与较差的饮食和较差的健康状况有关。因此，目前尚不清楚如何干预改变环境，使健康饮食成为青少年更容易的选择（或根本是一种选择），并使不健康饮食变得更困难（或不是唯一的选择）。拟议的项目将建立在先前工作的基础上并具有创新性。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步行范围内的各种食物来源。青少年患者利用独特的卫生系统数据集：包含临床和调查数据的电子病历 (EMR) 具体目标是： 目标 1. 对当地食物来源进行全面评估：青少年将评估地点和情况。提供全系列食品目标 2：为了生成一个新颖的综合多级数据库，Lucan 博士将把食物来源数据（来自目标 1）与其他本地数据以及青少年患者的数据合并。 （来自卫生系统 EMR） 目标 3. 评估当地食物来源与青少年饮食摄入量的关系 Lucan 博士将使用数据库（来自目标 2）来评估青少年家庭和学校周围的食物来源与青少年饮食摄入量的关系。他们报告的饮食摄入量（例如，水果、蔬菜和 这项 K23 工作的分析将是横向的，但方法、数据库和培训将直接为纵向研究奠定基础（例如，当地食物环境的变化与饮食相关的健康结果的变化有何关系）。例如突发性肥胖、糖尿病、血脂异常和高血压——所有这些都可以通过 EMR 中提供的临床数据进行。卢坎博士可以作为 R01 申请提交干预试验，以告知政策变化和改善食品。关于 Lucan 博士自己目前的技能组合，他确定了课程作业和指导学习 (GISc) 的一个主要重点领域以及三个支持领域（加密数据管理、统计分析以及行为和社交）。科学），他需要进行能够推动该领域发展的研究类型，卢肯博士将报名参加。 在 GISc 的正式证书课程中，并参加安全数据处理、多级建模、行为和社会科学理论课程。这些学习活动以及专家导师的指导研究将在研究中找到实际应用：GISc 到研究和培训活动将定义对当地食物来源的“暴露”、连接不同数据集的数据管理、为多层次分析提供信息的行为和社会科学理论、以及分析关联的回归模型和地理信息系统。的技能培训将在一流的研究和学习环境中进行敏感、多层次、多样化的空间数据，该机构和部门在 NIH 资助中都排名靠前，并且有特殊的资源、设施、人员、合作伙伴关系和专业知识来支持博士。 Lucan 的项目和培训需求在以患者为导向的行为研究方面具有多层次的 GISc 考虑，并且在社会科学、营养研究和涉及青少年的研究方面拥有丰富的专业知识，与 NICHD 有着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，以支持其作为独立调查员的职业生涯。
