The National Health and Aging Trends Study

项目摘要 这项申请的目的是扩展和加强国家健康和老龄化趋势研究(NHATS)， 一个研究晚年残疾趋势和轨迹的全国性平台。NHATS的总体目标是1) 促进对晚年残疾趋势和动态、其前因性和相关性的科学研究，以及 以及(2)推进对老年人残疾的社会和经济后果的研究 个人、家庭和社会。为了在下一个五年周期中实现这些目标，我们将继续独特的 NHATS的主要设计特征包括每年收集数据并亲自从国家代表那里收集数据 2019-2023年(第9-13轮)老年人样本(从联邦医疗保险登记文件中抽样)。我们还将 添加了几个创新的增强功能，侧重于认知和感觉能力的客观衡量标准，以及 体力活动。以这种方式扩展NHAT将允许解决重要的科学问题 关于残疾进程各组成部分的短期和长期深入趋势，以及 残疾开始、进展和恢复的动态。具体地说，在下一个周期中，NHATS将1)继续 收集经改进的残疾议定书和关于残疾先兆和残疾的补充问题 后果，包括主观和经济福祉、生活和护理安排以及年终质量 生命；并在第10轮(2020)补充样本，以保持NHATS生产5年的能力 估计(高达90+)和黑白比较；2)丰富和扩大NHATS年度衡量标准 残疾议定书，包括制定和实施a)一项新的基于iPad的议定书，以增强 认知和感觉能力的测量；以及b)使用加速度计对体力活动进行小组分研究； 以及3)记录和传播NHATS数据，提供链接的索赔文件和新的与政策相关的文件 联系，并为不断增长的NHATS用户社区提供新的培训机会。这些目标将允许 NHATS将实现其总体目标，即为科学研究提供一个平台，以指导减少 残疾，最大限度地发挥功能，并提高老年人的生活质量。

Project Summary The purpose of this application is to extend and enhance the National Health and Aging Trends Study (NHATS), a national platform for studying late life disability trends and trajectories. The overall aims of NHATS are to 1) promote scientific inquiry into late-life disability trends and dynamics, their antecedents and correlates, and disparities therein and (2) to advance study of the social and economic consequences of late-life disability for individuals, families, and society. To achieve these aims in the next five-year cycle, we will continue the unique key design features of NHATS including collecting data annually and in person from a nationally representative sample of older adults (sampled from the Medicare enrollment file) in 2019-2023 (Rounds 9-13). We will also add several innovative enhancements focused on objective measures of cognitive and sensory capacity and physical activity. Extending NHATS in this way will allow important scientific questions to be addressed concerning both shorter and longer-term in-depth trends in components of the disability process, as well as the dynamics of disability onset, progression and recovery. Specifically, in the next cycle NHATS will 1) Continue collection of the enhanced disability protocol and supplemental questions on disability antecedents and consequences including subjective and economic wellbeing, living and care arrangements, and quality of end of life; and replenish the sample in Round 10 (2020) in order to maintain NHATS' ability to produce 5-year age estimates (up to 90+) and Black-White comparisons; 2) Enrich and expand measurement in the NHATS' annual disability protocol including development and implementation of a) a new iPad-based protocol to enhance measures of cognitive and sensory capacity; and b) a panel substudy of physical activity using accelerometry; and 3) Document and disseminate NHATS data, make available linked claims files and new policy-relevant linkages, and provide new training opportunities to the growing NHATS user community. These aims will allow NHATS to achieve its overarching goal of providing a platform for scientific inquiry to guide efforts to reduce disability, maximize functioning, and enhance older adults' quality of life.
