DESCRIPTION (provided by applicant): The candidate, Marina Reznik, MD, MS is an Assistant Professor of Pediatrics at the Albert Einstein College of Medicine (Einstein), Children's Hospital at Montefiore (CHAM). Her long-term goal is to become a productive, independently funded clinical investigator with expertise in developing community-based interventions to improve the health care services and outcomes for medically underserved minority children with chronic diseases such as asthma and obesity. To achieve her goal, Dr. Reznik seeks to augment her prior basic training in clinical research methods and gain skills through combination of advanced didactic courses in behavioral methodology, qualitative research, advanced experimental designs and Community-Based Participatory Research (CBPR) and conducting proposed research. Her research is aimed at developing an intervention that will address barriers and facilitators to physical activity in inner-city minority elementary school students with asthma, more than half of whom are also overweight. Her research agenda is to generate rigorous evidence to improve physical activity in this vulnerable population through an intervention targeted to the needs of the community and developed in partnership with the community. Dr. Reznik proposes a two- phase project to develop and then evaluate a pilot intervention. In phase I, she will identify barriers and facilitators to physical activity using qualitative methods and inform intervention development (Specific Aims 1 and 2). Semi-structured interviews will be conducted with students, parents, school personnel and representatives from the community to identify barriers and facilitators to physical activity in children with asthma. Guided by the results of the qualitative analysis and CBPR principles, a Collaborative Board with representatives from the New York City Departments of Education and Health, South Bronx Asthma Partnership, schools, and parents will be established to provide feedback on intervention development. In phase II, the intervention will be tested via a pilot randomized controlled trial (RCT) for scientific and practical feasibility while assessing the proximal goal of improved physical activity levels, measured objectively with an accelerometer (Specific Aim 3). This pilot study will take place at four resource-poor elementary schools in the Bronx, New York. This study will inform a future large-scale cluster RCT to test the effectiveness of the developed intervention on improving physical activity and fitness levels, motivating behavior change, achieving healthier weight trajectories, and reducing asthma-related morbidity in inner-city minority students with asthma. In the rich research environment of Einstein and CHAM, Dr. Reznik will be guided by a team of three local experts in community-based clinical trials of obesity prevention (Dr. Wylie-Rosett); qualitative research, behavioral intervention trials and CBPR (Dr. Bauman); and clinical trials of school-based exercise intervention (Dr. Ozuah). Advisory committee includes strong foundation in clinical trials of asthma interventions (Drs. Crain and Cabana), design and analysis of clinical trials (Dr. Kim) and exercise physiology (Dr. Rowlands).

描述（由申请人提供）：候选人Marina Reznik，医学博士，MS是阿尔伯特爱因斯坦医学院（爱因斯坦），蒙蒂菲奥里儿童医院（CHAM）的儿科助理教授。她的长期目标是成为一个富有成效的，独立资助的临床研究者，在开发社区为基础的干预措施，以改善医疗服务不足的少数民族儿童慢性疾病，如哮喘和肥胖的医疗保健服务和结果的专业知识。为了实现她的目标，Reznik博士寻求增强她在临床研究方法方面的先前基础培训，并通过结合行为方法学，定性研究，先进的实验设计和基于社区的启发性研究（CBPR）的高级教学课程来获得技能，并进行拟议的研究。她的研究旨在开发一种干预措施，以解决患有哮喘的市中心少数民族小学生进行体育活动的障碍和促进因素，其中一半以上也超重。她的研究议程是通过针对社区需求的干预措施，并与社区合作开发，以产生严格的证据来改善这一弱势群体的体育活动。Reznik博士提出了一个两阶段的项目来开发和评估试点干预措施。在第一阶段，她将使用定性方法确定身体活动的障碍和促进因素，并为干预措施的制定提供信息（具体目标1和2）。将与学生、家长、学校工作人员和社区代表进行半结构化访谈，以确定哮喘儿童体力活动的障碍和促进因素。在定性分析结果和CBPR原则的指导下，将成立一个由来自纽约市教育和卫生部、南布朗克斯哮喘伙伴关系、学校和家长的代表组成的合作委员会，以提供干预措施制定方面的反馈。在第二阶段，将通过一项试点随机对照试验（RCT）测试干预措施的科学性和实际可行性，同时评估改善身体活动水平的近端目标，用加速度计客观测量（具体目标3）。这项试点研究将在纽约布朗克斯的四所资源贫乏的小学进行。这项研究将为未来的大规模随机对照试验提供信息，以测试所开发的干预措施在改善身体活动和健身水平，激励行为改变，实现更健康的体重轨迹以及降低市中心少数民族哮喘学生哮喘相关发病率方面的有效性。在Einstein和CHAM丰富的研究环境中，Reznik博士将由三名当地专家组成的团队指导，进行基于社区的肥胖预防临床试验（Wylie-Rosett博士）;定性研究，行为干预试验和CBPR（Bauman博士）;以及基于学校的运动干预临床试验（Ozuah博士）。咨询委员会包括哮喘干预临床试验（Crain和Cabana博士），临床试验设计和分析（Kim博士）和运动生理学（Rowlands博士）的坚实基础。
