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(AG154124，1/15/1998-12/31/2002)再延长5年(从1/1/04至12/31/08)。在下一阶段，这项研究有四个目标：(A)对照美国，分析日本和台湾老年人残疾的长期趋势；(B)评估个人在老年时的健康轨迹；(C)检查社会关系和经济福祉对性别、种族和几个老年人队列的健康轨迹的影响；以及(D)比较上述联系在美国、日本和台湾的异同。 拟议的研究需要结合一手和二手数据分析。首先，关于美国老年人的数据将来自NIA支持的三项由密歇根大学研究人员进行的纵向研究。其中包括(A)高龄老年人的资产和健康动态(AHEAD)，(B)美国人改变生活(ACL)，以及(C)老年人的幸福感：个人控制和自尊(WBA)。其次，有关日本老年人的数据将来自一项对3000多名老年人进行的为期18年的7波小组研究。第三，在台湾，数据将来自一项对大约4000名老年人进行的为期14年的5波小组研究。除了次要数据外，还将在这三个国家积累主要数据。然而，只要求对日本的主要数据收集提供部分支持。在其他研究中进一步收集数据的资金已从其他来源获得。最后，在日本收集的数据将及时提供给研究界进行进一步分析，从而最大限度地提高这一行动的生产率。 这项研究是密歇根大学老年学研究所(UM/IoG)、东京都老年学研究所(TMIG)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成果。由于这三家机构都坚定地致力于这项研究倡议，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.
