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Albert Einstein医学院（Einstein）的儿科助理教授，Montefiore（CHAM）的儿童医院。她的长期目标是成为一名富有成效的，独立资助的临床研究者，在开发基于社区的干预措施方面具有专业知识，以改善医疗服务和慢性疾病（如哮喘和肥胖症）的医疗服务不足的少数民族儿童的成果。为了实现她的目标，Reznik博士试图通过结合了行为方法论，定性研究，先进的实验设计和基于社区的参与性研究（CBPR）和进行拟议的研究来增强她先前在临床研究方法中的基本培训，并提高技能。她的研究旨在制定一种干预措施，该干预措施将解决哮喘内城市小学生的体育锻炼的障碍和促进者，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来产生严格的证据，以改善这一脆弱人群的体育活动，并与社区合作发展。 Reznik博士提出了一个两期项目，以开发然后评估试点干预措施。在第一阶段，她将使用定性方法确定体育锻炼的障碍和促进者（特定目的1和2）。将与社区的学生，父母，学校人员和代表进行半结构化访谈，以确定哮喘儿童体育锻炼的障碍和促进者。在定性分析和CBPR原则的结果的指导下，该委员会与纽约市教育和健康部门的代表，South Bronx哮喘伙伴关系，学校和家长建立，以提供有关干预发展的反馈。在第二阶段中，将通过试验随机对照试验（RCT）测试干预措施，以实现科学和实际的可行性，同时评估改善体育活动水平的近端目标，并用加速度计客观地测量（特定的目标3）。这项试点研究将在纽约布朗克斯市的四所资源贫乏的小学举行。这项研究将为未来的大规模集群RCT提供信息，以测试开发的干预措施在改善体育锻炼和健身水平，激励行为改变，实现更健康的体重轨迹以及降低哮喘内城市少数族裔学生中与哮喘相关的发病率的有效性。在爱因斯坦和Cham的丰富研究环境中，Reznik博士将由三名基于社区的肥胖症临床试验的本地专家组成的团队（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（Ozuah博士）的临床试验。咨询委员会包括哮喘干预临床试验（Crain和Cabana博士），临床试验的设计和分析（KIM博士）和运动生理学（Rowlands博士）的强大基础。
