ASSET AND HEALTH DYNAMICS AMONG THE OLDEST OLD

高龄老人资产与健康动态（AHEAD）研究 目前作为健康和退休的竞争补充资金 调查（HRS）。 AHEAD利用多个成本节约机会 由HRS提供。 HRS对约69，000个家庭进行了筛查， 独特的机会，同时确定家庭， 1923年或以前出生的人（1993年为70岁以上）。 劳动密集 HRS的设计阶段也在调查设计方面取得了创新（例如， 重复采样程序，实验模块，新方法， 无响应转换）和测量（例如，括号内的不答复 金融问题，概率量表，认知性能测试） 这对于理解 健康、经济福利和家庭资源之间的相互作用 老年人口。 根据合作协议，AHEAD获得了两个奖项的支持 国家情报局和密歇根大学之间 第一个奖项（U 01 AG 09740， 1992年4月1日至1992年12月31日）支持AHEAD的设计阶段;第二和 目前的合同（U 01 AG 09740，1993年1月1日至1994年12月31日）为基线提供资金 数据收集。 与HRS父母补助金一样， 仅为数据的收集和分发提供支持， 研究社区。 AHEAD在很大程度上与HRS共享高级研究和现场工作人员， 调查对健康和财富动态有着共同的兴趣。 尽管如此，它们仍值得单独审议，因为实质性问题 激励他们的问题是足够明显的，反映了重要的 目标人群生命周期各阶段的差异， 公共政策和这些阶段特有的社会背景。

The study of Asset and Health Dynamics (AHEAD) among the Oldest Old is currently funded as a competing supplement to the Health and Retirement Survey (HRS). AHEAD capitalizes on several cost-saving opportunities afforded by HRS. The HRS screening of some 69,000 households provided a unique opportunity to identify simultaneously households containing persons born in 1923 or earlier (aged 70+ in 1993). The labor intensive design phase of the HRS also yielded innovations in survey design (e.g., replicate sampling procedures, experimental modules, new approaches to non-response conversion) and measurement (e.g., bracketing non-responses to financial questions, probability scales, cognitive performance testing) which have important implications for understanding the dynamic interaction among health, financial well-being, and family resources in an older population. AHEAD has been supported by two awards under a cooperative agreement between NIA and the University of Michigan. The first award (U01 AG09740, 4/1/92-12/31/92) supported the design phase of AHEAD; the second and current award (U01 AG09740, 1/1/93-12/31/94) provides funds for baseline data collection. Like the HRS parent grant, the competing supplements provide support only for the collection and distribution of data to the research community. AHEAD largely shares senior research and field staffs with HRS and the two surveys have a common interest in health and wealth dynamics. Nonetheless, they warrant separate consideration because the substantive issues which motivate them are sufficiently distinct, reflecting important differences in the life-cycle stages of their target populations and the public policy and social contexts unique to these stages.
