DESCRIPTION (provided by applicant): The obesity epidemic disproportionately affects the 1.2 million U.S. households living in public housing, where nearly 50% of adults are obese and have a two-fold greater risk of hypertension. Using an ecologic framework, we propose that neighborhood social network factors likely promote unhealthy lifestyle behaviors that contribute to this disparity. The overall objective of this proposal is to identify social network factors tha promote healthy diet, physical activity and healthy weight among public housing residents. We focus on the social network - the connections among people within a community - as theoretical work suggests that social networks have an important influence on health behaviors. However, no previous studies have examined lifestyle behaviors in a social network analysis or targeted these behaviors with a social network intervention. We will explore three aims: 1) To characterize the relationship between the social network and obesity / lifestyle behaviors of 500 adults living in public housing developments in Baltimore, MD; 2) To assess if an interaction between the social network and built environment exists and how such an interaction influences the lifestyle behaviors among public housing residents; and 3) To develop a social network intervention to facilitate lifestyle behavior change and pilot test it in residents of public housig developments as in Baltimore, MD. The candidate's long-term career goal is to improve the health of at-risk populations by preventing and treating obesity and cardiovascular disease (CVD). She completed a Clinical Research Fellowship in General Internal Medicine (GIM) at Johns Hopkins, and joined the GIM faculty as an Assistant Professor at Johns Hopkins in July 2012. She has laid out a career development plan to enhance her skills in advanced statistical methods, social network analysis, and behavioral theory. She has also assembled a core mentorship team along with a multidisciplinary advisory committee to support her research and career development. Her core mentorship team is headed by her primary mentor, Dr. Jeanne Clark, Professor of Medicine and Epidemiology, who has extensive experience in mentoring and clinical trials for the prevention and treatment of obesity. This core team also includes Dr. Carl Latkin, Professor of Public Health with expertise in social networks, and Dr. David Levine, Professor of Medicine with expertise in community-based participatory research and CVD risk reduction. In year 5, the results from this work will lead to an R01 application to conduct a randomized controlled trial testing the effect of the social network intervention on healthy lifestyle behavior change that promotes and sustains a healthy weight among the high-risk public housing population.

描述（由申请人提供）：肥胖流行不成比例地影响居住在公共住房中的120万美国家庭，那里近50％的成年人肥胖，高血压的风险更大。使用生态框架，我们建议社区社交网络因素可能促进不健康的生活方式行为，从而导致这种差异。该提案的总体目的是确定社交网络因素促进公共住房居民中健康饮食，体育锻炼和健康体重。我们专注于社交网络 - 社区中人们之间的联系 - 理论工作表明，社交网络对健康行为有重要影响。但是，以前没有研究检查社交网络分析中的生活方式行为或通过社交网络干预针对这些行为。我们将探讨三个目标：1）表征居住在马里兰州巴尔的摩市公共住房发展中的500名成年人的社交网络与肥胖 /生活方式行为之间的关系； 2）评估社交网络与建筑环境之间的相互作用以及这种互动如何影响公共住房居民之间的生活方式行为； 3）开发社交网络干预措施，以促进生活方式行为的改变，并在马里兰州巴尔的摩（Baltimore）和公共Housig Developments的居民中对其进行测试。候选人的长期职业目标是通过预防和治疗肥胖和心血管疾病（CVD）来改善高危人群的健康。她在约翰·霍普金斯（Johns Hopkins）完成了一项临床研究奖学金（GIM），并于2012年7月加入了约翰·霍普金斯（Johns Hopkins）的助理教授。她还与多学科咨询委员会一起组建了一个核心指导团队，以支持她的研究和职业发展。她的核心指导团队由她的主要导师，医学和流行病学教授珍妮·克拉克（Jeanne Clark）博士领导，她在预防和治疗肥胖症方面具有丰富的指导和临床试验经验。该核心团队还包括具有社交网络专业知识的公共卫生教授Carl Latkin博士，以及具有社区参与性研究和CVD降低风险的专业知识的医学教授David Levine博士。在第五年，这项工作的结果将导致R01应用，以进行随机对照试验，该试验测试社交网络干预对健康生活方式行为变化的影响，从而促进和维持高风险的公共住房人群中健康的体重。
