Experience Corps Trial: Improving Health of Older Populations through Generativit

描述（由申请人提供）：预计到2020年，老年人的数量将增加一倍，65岁及以上人口的比例预计将上升至22%，为我们的老龄化社会开发和试验以人口为基础的大规模、有效的健康促进方法至关重要。这将有助于就如何部署资源作出基于证据的决定，以便对老年人的健康产生最佳影响。该行政核心通过对体验团项目及其成本效益和成本效益在当地和社会的影响进行随机对照试验，支持致力于实现这一目标的项目项目的运作和整体协调。这个项目是一个老年志愿者项目，让60岁以上的老人在公立小学担任有意义的角色，这些角色对孩子们的成就有很大的影响；这个项目吸引并留住了老年人，每周15个小时，因为它有机会回馈社会。然而，该方案的设计是一个健康促进方案，旨在增加社会、认知和身体活动。该应用程序将在大学-社区-城市合作中，通过随机对照评估对扩大项目的影响进行严格评估：对老年志愿者进行评估，以确定Experience Corps是否可以预防或减缓身体残疾、跌倒和认知能力下降（项目1）；在学校，确定孩子们是否因为体验团提供的社会资本而在学业、行为和学习准备方面有所提高，从而改善我们的老龄化社会（项目2）；节目作用对大脑结构和执行功能的潜在影响机制（项目3）；项目对社会和心理机制和结果的影响（项目4）；最后，我们将对该项目进行成本效益分析，同时考虑到对老年人和儿童的影响。5个项目和3个支持核心的工作将相互联系和协同，并将通过在该行政核心（核心a）内运作的指导委员会和执行委员会进行协调。该核心负责所有项目和核心的项目协调和交叉数字化、整体组织和预算管理、监控进度和有效性、编写报告、组织DSMB会议并协调社区关系。总的来说，该项目旨在评估经验团作为促进老龄化社会健康的社会模式的效用和有效性。

DESCRIPTION (provided by applicant): With the number of older adults expected to double and the proportion of people 65 and older expected to rise to 22% by 2020, it is critical to develop and test population-based approaches for large scale, effective health promotion for our aging society. This will permit evidence-based decisions as to how to deploy resources in order to have optimal impact on the health of older adults. This Administrative Core supports the operations and overall coordination of a program project dedicated to contributing to this goal by conducting a randomized, controlled trial of the Experience Corps program and its cost-effectiveness and cost-benefit impact locally and societally. This program is a senior volunteer program which places people 60 and older in meaningful roles in public elementary schools, roles designed to have high impact on children's' outcomes; the program attracts and retains older adults, 15 hours per week, for its opportunity to give back. However, designed into the program is a health promotion program, intending to increase social, cognitive and physical activity. This application will, in a University-community-city collaboration, conduct a rigorous evaluation of the impact of the scaled-up program through a randomized controlled evaluation: of older volunteers to determine whether Experience Corps prevents or slows physical disability, falls and cognitive decline (Project 1); of schools, to determine if children improve academically, behaviorally and in readiness to learn as a result of the social capital offered by Experience Corps and, hence, our aging society (Project 2); of the potential mechanisms of program action on brain structure and executive function (Project 3); of program effects on social and psychological mechanisms and outcomes (Project 4); and, finally, we will conduct a cost-benefit analysis of the program, taking impact on both older adults and children into account. The work of the 5 projects and 3 supporting cores will be mutually interconnected and synergistic, and will be interdigitated through a Steering Committee and an Executive Committee operated within this Administrative Core (Core A). This Core will project coordination and interdigitation, overall organization and budget management for all Projects and cores, monitor progress and effectiveness, produce reports, organize DSMB meetings, and coordinate community relations. Overall, this program project is designed to evaluate the utility and effectiveness of Experience Corps as a social model for health promotion for an aging society.
