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.

识别并理清社会和物理环境对不同青少年和青少年身体活动的影响 青壮年人口 项目概要和摘要 该 K01 奖项的目的是为 Leah Frerichs 博士成为独立人士提供发展支持 青年参与研究的调查员使用移动技术和系统科学方法来解开和 解决社会和物理环境对身体活动的影响。 在青春期和成年早期，新出现的证据表明社会和青年期。 物理环境在塑造身体活动行为方面起着至关重要的作用，但我们在这方面还存在重大差距。 理清不同社会过程的影响（基于行为和相似性的友谊建立与基于行为和相似性的友谊建立 采用朋友的行为）和共同暴露于外源影响，例如建立的活动促进 环境特征对活动行为的影响，特别是农村低收入社区的非裔美国青年。 梳理这些相互交织的环境影响需要关于真实情况的高有效性、细粒度、纵向数据。 通过这款 K01，Frerichs 博士将了解青少年社交网络、环境暴露和活动行为的时间变化。 凭借她在社区研究和系统科学方面的经验，获得正式的教学和实践机会 纵向社交网络和空间分析方法、加速度数据处理和分析的指导， 移动技术数据收集方法、制定基于网络和移动的干预策略，以及 拟议的研究包括社会和行为研究伦理以及负责任的研究行为。 分析使用智能手机中嵌入的传感器收集的丰富数据，这些数据提供有关社交的实时客观数据 Frerichs 博士将使用该数据来分析大学生之间的互动、地理编码位置数据和身体活动水平。 二次分析的结果和经验可为青少年的主要数据收集研究提供信息 借助这些数据和先进的网络建模技术，我们将研究农村的非裔美国人。 关于网络、环境和行为的未解答的问题。你的同伴的活动对你的影响有多大。 或者你的活动行为决定了你的同伴是谁？以及你与之互动的空间？ 您的同龄人影响您的活动水平吗？此外，我们将在关键的青春期研究这些问题，以了解您的活动水平。 年轻成年人口，包括在非裔美国人农村社区内，我们在该社区存在严重的研究空白。 最后，Frerichs 博士将使用创新的青年参与和参与系统科学方法来转化 新的社会和物理环境干预策略的研究结果。 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，利用移动技术来解决 社会和物理环境对服务不足的社区中与肥胖相关的生活方式行为有影响。
