Experience Corps Trial: Improving Health of Older Populations through Generativit

描述(由申请人提供)：到2020年，老年人的数量预计将翻一番，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测试基于人口的方法以实现大规模、有效的健康促进至关重要。这将使人们能够根据证据作出决定，决定如何分配资源，以便对老年人的健康产生最佳影响。该管理核心通过对Experience Corps计划及其对当地和社会的成本效益和成本效益的影响进行随机对照试验，支持致力于促进这一目标的计划项目的运作和整体协调。该计划是一个高级志愿者计划，让60岁及以上的人在公立小学担任有意义的角色，这些角色旨在对儿童的成绩产生很大影响；该计划吸引并留住老年人，每周15小时，以换取回报的机会。然而，该计划中设计了一个健康促进计划，旨在增加社交、认知和身体活动。这项应用将通过大学-社区-城市合作，通过随机对照评估对扩大计划的影响进行严格评估：对老年志愿者进行评估，以确定体验团是否预防或减缓身体残疾、跌倒和认知下降(项目1)；对学校进行评估，以确定儿童是否由于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改善(项目2)；计划对大脑结构和执行功能的潜在作用机制(项目3)；计划对社会和心理机制和结果的影响(项目4)；最后，我们将对该计划进行成本效益分析，同时考虑到对老年人和儿童的影响。5个项目和3个支助核心的工作将相互关联和协同，并将通过在本行政核心(核心A)内运作的指导委员会和执行委员会相互交错。该核心将对所有项目和核心进行项目协调和交叉，对所有项目和核心进行全面组织和预算管理，监测进展和成效，编制报告，组织数字业务和预算管理委员会会议，并协调社区关系。总体而言，该计划项目旨在评估体验团作为老龄化社会健康促进的社会模式的实用性和有效性。

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.
