Identifying and disentangling social and physical environmental effects on physical activity in diverse adolescent and young adult populations PROJECT SUMMARY AND ABSTRACT The purpose of this K01 award is to provide developmental support to Dr. Leah Frerichs to become an independent investigator in youth-engaged research using mobile technology and systems science methods to disentangle and address social and physical environment influences on physical activity. Physical activity levels dramatically decrease in adolescence and young adulthood. During these developmental periods, emerging evidence indicates the social and physical environment plays a critical role in shaping physical activity behaviors. However, we have a critical gap in disentangling the effects of different social processes (friendship initiation based on behaviors and similarities versus adoption of friend’s behaviors) and shared exposures to exogenous influences such as activity-promoting built environment features on activity behaviors, especially among African American youth in rural, low-income communities. Teasing apart these intertwined environmental influences requires high-validity, fine-grained, longitudinal data on real- time changes in youth’s social networks, environmental exposures and activity behaviors. With this K01, Dr. Frerichs will build on her experience in community-based research and systems science to obtain formal didactic and hands-on instruction in longitudinal social network and spatial analysis methods, processing and analysis of accelerometry data, mobile technology data collection methods, development of network- and mobile-based intervention strategies, and social and behavioral research ethics and responsible conduct in research. The proposed studies include a secondary analysis of rich data collected using sensors embedded in smartphones that provided real-time objective data on social interactions, geo-coded location data, and physical activity levels among college students. Dr. Frerichs will use the findings and experience from the secondary analysis to inform a primary data collection study with adolescent youth in a rural, African American population. With these data and advanced network modeling techniques, we will examine unanswered questions about networks, environments, and behavior. How much does your peers’ activity influence your own activity? Or do your activity behaviors determine who your peers are? And do the spaces where you interact with your peers influence your activity levels? Furthermore, we will examine these questions across critical adolescence to young adult populations, including within a rural African American community where we have critical research gaps. Finally, Dr. Frerichs will use innovative youth-engaged and participatory systems science methods to translate the findings into new social and physical environment intervention strategies. The proposed training and expert mentoring team will provide Dr. Frerichs with the set of skills and preliminary data needed to successfully compete for R01 funding and to serve as a leader in the field of youth-engaged intervention research that uses mobile technology to address social and physical environment influences on obesity-related lifestyle behaviors in underserved communities.

识别和解开社会和物理环境对不同青少年和青少年体育活动的影响 青壮年人口 项目总结和摘要 这个K01奖的目的是提供发展支持博士利亚Frerichs成为一个独立的 研究人员利用移动的技术和系统科学方法， 解决社会和物理环境对身体活动的影响。身体活动水平急剧下降， 青春期和青年期。在这些发展时期，新出现的证据表明， 物理环境在形成体育活动行为中起着关键作用。然而，我们在以下方面存在严重差距： 解开不同社会过程的影响（基于行为和相似性的友谊开始， 采用朋友的行为）和共同暴露于外部影响，如活动促进建立 环境对活动行为有影响，特别是在农村、低收入社区的非裔美国青年中。 要区分这些相互交织的环境影响，需要高有效性、细粒度、纵向的真实的数据， 青少年社交网络、环境暴露和活动行为的时间变化。有了这个K01，Frerichs博士将 建立在她的经验，以社区为基础的研究和系统科学，以获得正式的教学和动手 纵向社会网络和空间分析方法，加速度测量数据的处理和分析， 移动的技术数据收集方法，开发基于网络和移动的干预策略，以及 社会和行为研究道德以及负责任的研究行为。拟议的研究包括一个二级 分析使用智能手机中嵌入的传感器收集的丰富数据，这些传感器提供有关社交网络的实时客观数据。 互动，地理编码的位置数据，以及大学生的身体活动水平。Frerichs博士将使用 二次分析的结果和经验，以告知一个主要的数据收集研究与青少年在一个 农村，非裔美国人。有了这些数据和先进的网络建模技术，我们将研究 关于网络、环境和行为的未解答问题。你的同伴的活动对你的影响有多大？ 自己的活动？或者你的活动行为决定了你的同龄人是谁？你可以在这些空间里 你的同龄人影响你的活动水平？此外，我们将在关键的青春期检查这些问题， 年轻的成年人，包括在农村非洲裔美国人社区，我们有关键的研究差距。 最后，Frerichs博士将使用创新的青年参与和参与式系统科学方法来翻译 研究结果纳入新的社会和物理环境干预战略。拟议的培训和专家辅导 团队将为Frerichs博士提供成功竞争R01资金所需的一套技能和初步数据 并成为青年参与干预研究领域的领导者，该研究使用移动的技术来解决 社会和物理环境对服务不足社区中肥胖相关生活方式行为的影响。
