R03Activity Code Description:
To provide research support specifically limited in time and amount for studies in categorical program areas. Small grants provide flexibility for initiating studies which are generally for preliminary short-term projects and are non-renewable. |
Prepartaion and Distribution of the Nujlsoa
DESCRIPTION (provided by applicant): The aim of this project is to distribute to the international research community two waves of data from the Nihon University Japanese Longitudinal Study of Aging (NUJLSOA). These nationally representative data of the population 65 years of age and over should provide the empirical basis for numerous studies on a variety of aging issues in Japan, comparing the U.S. and Japanese experiences, and including the Japanese experience among a set of international experiences. The aim is, thus, to provide a significant research resource to the international research community. The NUJLSOA is a longitudinal survey of a nationally representative sample of the population aged 65 and over in Japan. The sample is refreshed with younger members at each wave to retain this aspect at each wave. It was designed primarily to investigate health status of the Japanese elderly and changes in health status over time. The first wave of data was collected in November 1999, the second in November 2001, and a third wave is expected in November 2003. While the focus of the survey is health and health service utilization, other topics relevant to the aging experience are included such as intergenerational exchange, living arrangements, care giving, and labor force participation. The project will produce an English language copy of the survey instruments and English language codebooks for two waves of data. These along with SAS files and data files will be provided on a CD-ROM for distribution to the research community. In order to acquire use of the data, researchers must agree to use the data only for research purposes and not to use data to describe or identify individuals.

P01Activity Code Description:
For the support of a broadly based, multidisciplinary, often long-term research program which has a specific major objective or a basic theme. A program project generally involves the organized efforts of relatively large groups, members of which are conducting research projects designed to elucidate the various aspects or components of this objective. Each research project is usually under the leadership of an established investigator. The grant can provide support for certain basic resources used by these groups in the program, including clinical components, the sharing of which facilitates the total research effort. A program project is directed toward a range of problems having a central research focus, in contrast to the usually narrower thrust of the traditional research project. Each project supported through this mechanism should contribute or be directly related to the common theme of the total research effort. These scientifically meritorious projects should demonstrate an essential element of unity and interdependence, i.e., a system of research activities and projects directed toward a well-defined research program goal. |
Health and Survival Among Elderly Women and Men in Three Asian Countries
This project aims to advance our understanding of sex differences in health by analyzing newly available longitudinal data on older adults living in Japan, Singapore, and the Philippines. Previous research on sex differences in health has identified a paradox. Women have lower mortality than men, but they have higher morbidity, functional limitation, disability, and worse self-rated health. Yet, recent studies suggest that this health-survival paradox may be partly due to the particular dimensions of health examined, how they are measured, which subgroups of populations are examined, and the periods in which the studies are conducted. Some studies also suggest that women's higher self-reported rates of functional loss and disability may partly reflect differential assessment and reporting of these conditions by sex. When, to what extent, and why the above health-survival paradox by sex exists are not fully understood in Western developed countries, but the gap in knowledge is even greater for contexts outside the West due to limited availability of appropriate data and a lack of rigorous systematic analysis on the topic. We will utilize data that we have been and will be collecting in Japan, Singapore, and the Philippines, which provide an unusually rich source of information on multiple dimensions of health for large, nationally representative samples of older populations in Asia. Each dataset also contains a wide range of detailed data on social, economic, psychological, and behavioral characteristics that are critical to understanding the complex paths and processes leading to sex differences in health. Such rich information on older populations is rare outside Western developed countries. We will take advantage of these data and conduct rigorous and systematic analyses of sex differences in health and their underlying causes in Asia. We will first examine sex differences across multiple dimensions and measures of health, then explore various pathways and processes underlying these outcomes. Because these datasets are designed to be comparable across most measures, they also provide a valuable opportunity to test the extent to which findings vary across the three settings. We will also compare our findings with US and Danish results. RELEVANCE (See instructions): Is it true that males are healthier than females but die younger? If so, why? This research Project addresses these questions concerning the human health-survival paradox. Findings will provide a deeper understanding of the basis for sex differences in health and survival[unreadable]and of the opportunities that society and particularly health professionals have to improve health and survival for males and females.
