The National Health and Aging Trends Study

项目摘要 该应用程序的目的是扩展和加强国家健康和老龄化趋势研究（NHATS）， 研究晚年残疾趋势和轨迹的国家平台。NHATS的总体目标是： 促进对晚年残疾趋势和动态及其前因和相关因素的科学调查， （2）促进对老年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实现这些目标，我们将继续采取独特的 NHATS的主要设计特点，包括每年收集数据和亲自向国家代表收集数据 2019-2023年（第9-13轮）的老年人样本（从Medicare登记文件中抽样）。我们还将 增加了几项创新的增强功能，重点是认知和感官能力的客观测量， 体力活动。以这种方式扩展NHATS将允许解决重要的科学问题 关于残疾进程各组成部分的较短期和较长期的深入趋势，以及 残疾发生、发展和恢复的动态。具体而言，在下一个周期，NHATS将1）继续 收集增强的残疾议定书和关于残疾前因的补充问题， 后果，包括主观和经济福祉，生活和护理安排，以及 寿命;并在第10轮（2020年）补充样本，以保持NHATS生产5年年龄的能力 估计（高达90+）和黑白比较; 2）丰富和扩大NHATS年度 残疾协议，包括制定和实施a）一个新的基于iPad的协议，以加强 认知和感觉能力的测量;和B）使用加速度计的身体活动的小组子研究; 3）记录和传播NHATS数据，提供链接的索赔文件和新的政策相关 这将有助于加强国家生境服务系统的联系，并为日益增多的国家生境服务系统用户提供新的培训机会。这些目标将使 NHATS实现其总体目标，即提供一个科学研究平台，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.
