Health and Well-Being Among Older-Old in U.S. and Japan

描述（由申请人提供）：本申请旨在将“美国和日本老年人的健康和福祉”项目（AG 154124，1/15/1998-12/31/2002）再延长五年（从1/1/04到12/31/08）。在下一阶段，这项研究有以下四个目标：（a）分析日本和台湾老年人残疾的长期趋势，并与美国的老年人进行对比，（B）评估老年人的个人健康轨迹，（c）检查社会关系和经济状况对不同性别、种族和几个老年人群体健康轨迹的影响，以及（d）对比美国上述联系的相似性和差异，日本和台湾。 拟议的研究需要结合主要和次要数据分析。首先，关于美国老年人的数据将来自密歇根大学研究人员进行的三项NIA支持的纵向研究。这些项目包括：（a）高龄老人的资产和健康动态（AHEAD）;（B）美国改变生活（ACL）;（c）老年人的福祉：个人控制和自尊（WBA）。第二，日本老年人的数据将来自一项为期18年、涵盖3,000多名老年人的7波小组研究。第三，在台湾，数据将来自对约4 000名老年人进行的为期14年的5波小组研究。除了二级数据外，还将在所有三个国家积累初级数据。然而，只要求对日本的原始数据收集提供部分支持。已从其他来源获得资金，用于在其他研究中进一步收集数据。最后，将及时向研究界提供在日本收集的数据，以供进一步分析，从而最大限度地提高这一行动的生产力。 这项研究是由密歇根大学老年学研究所（UM/IoG），东京都老年学研究所（THEOTH）和台湾国家健康促进局（TBHP）在20世纪80年代中期发起的合作的产物。由于这三个机构都坚定地致力于这项研究计划，因此将分担融资责任，使其成为对美国国立卫生研究院极具吸引力的投资。

DESCRIPTION (provided by applicant): This application seeks to extend the project, "Health and Well-Being Among Older Old in U.S. and Japan" (AG154124, 1/15/1998-12/31/2002) for another five years (from 1/1/04 to 12/31/08). During the next period, this study has the following four aims: (a) analyze the long-term trends of disability among older adults in Japan and Taiwan in contrast to those in the United States, (b) evaluate individual health trajectories in old age, (c) examine the effects of social relations and financial well-being on health trajectories across gender, ethnic groups, and several cohorts of older adult, and (d) contrast the similarities and differences in the aforementioned linkages in the U.S., Japan, and Taiwan. The proposed study entails a combination of primary and secondary data analyses. First, data on older Americans will come from three NIA-supported longitudinal studies conducted by investigators at the University of Michigan. These include (a) the Asset and Health Dynamics Among the Oldest Old (AHEAD), (b) the American Changing Lives (ACL), and (c) Well-Being Among the Aged: Personal Control and Self-Esteem (WBA). Second, data on Japanese older people will come from an 18-year 7- wave panel study of over 3,000 older adults. Third, in Taiwan data will be derived from a 14-year 5- wave panel study of some 4,000 older persons. In addition to the secondary data, primary data will be accumulated in all three nations. However, only partial support for primary data collection in Japan is requested. Funding for further data collection in other studies has been secured from other sources. Finally, data collected in Japan will be provided to the research community in a timely fashion for further analysis, hence maximizing the productivity of this operation. This research is an outgrowth of the collaboration initiated in the mid-1980s by the University of Michigan Institute of Gerontology (UM/IoG), the Tokyo Metropolitan Institute of Gerontology (TMIG), and the Taiwan National Bureau of Health Promotion (TBHP). As all three institutions are strongly committed to this research initiative, the responsibility of financing will be shared, making it an extremely attractive investment for the National Institutes of Health.
