Integrated Health Interview Series

描述(由申请人提供)：国家健康访谈调查(NHIS)是运行时间最长的联邦调查之一，也是有关美国人不断变化的健康状况的主要信息来源。然而，目前，NHIS在长期变化研究中的利用不足。调查设计的复杂性和现有公共使用档案的文件结构使得NHIS即使对于单个年份的分析也很笨拙；跨调查年份的不兼容性--尤其是跨调查设计期的不兼容性--使许多研究人员无法进行长期的年表分析。 这项提案寻求资金，以创建综合健康访谈系列(IHIS)，其中包括1963年至2003年期间的NHIS数据和文件。IHIS将简化对300多个不同数据文件中300多万名受访者的约6,000个变量的访问。它将使研究人员能够在公共卫生领域40年的戏剧性变化中进行一致的比较，从而将美国人的健康状况作为一个动态过程进行研究，从而使NHIS数据的价值成倍增加。IHIS将产生大量新的科学和政策相关研究，涉及健康行为和差异、获得和使用医疗保健、人口老龄化、实现公共卫生目标(如2010年健康人倡议)的进展，以及许多其他主题。该项目利用了之前在收集NHIS数据和明尼苏达州人口中心数据基础设施项目方面的联邦投资。信息和信息系统项目由四个相互关联的部分组成：1)设计部分，用于制定全面的数据整合计划，涵盖数据结构、可变编码方案和新的变量，以提高可用性；2)数据改进部分，用于创建1963至1968年的新公共用途文件，并在整个数据系列中分配缺失和不一致的数据值；3)文件部分，提供全面的综合XML元数据，包括广泛覆盖每个变量随时间的可比性；以及4)数据访问部分，允许基于网络检索数据和文件，具有变量搜索、自动文件合并和数据重新格式化的能力。

DESCRIPTION (provided by applicant): The National Health Interview Survey (NHIS) is one of the longest-running federal surveys and is the principal source for information on the changing health of Americans. Presently, however, the NHIS is underutilized for the study of long-term change. The complexities of the survey design and file structures of the existing public use files make the NHIS unwieldy even for analysis of single years; the incompatibilities across survey years--and particularly across survey design periods--make the cost of long-run chronological analysis prohibitive for many researchers. This proposal seeks funding to create an Integrated Health Interview Series (IHIS) comprised of NHIS data and documentation for the period 1963 to 2003. The IHIS will simplify access to approximately 6,000 variables on over three million respondents contained in over 300 different data files. It will multiply the value of NHIS data by allowing researchers to make consistent comparisons through four decades of dramatic change in public health, and thus to study the health status of Americans as a dynamic process. The IHIS will result in a substantial body of new scientific and policy-relevant research into health behavior and disparities, access to and use of medical care, population aging, progress toward public health goals like the Health People 2010 initiatives, and many other topics. The project leverages previous federal investments in collecting the NHIS data and in data infrastructure projects at the Minnesota Population Center. The IHIS project consists of four interrelated components: 1) a design component to develop a comprehensive data integration plan covering data structures, variable coding schemes, and new variables to enhance usability; 2) a data improvement component to create new public use files for 1963 to 1968 and to allocate missing and inconsistent data values throughout the data series; 3) a documentation component offering comprehensive integrated XML metadata, including extensive coverage of the comparability of each variable across time; and 4) a data access component allowing web-based retrieval of data and documentation, with capabilities for variable search, automated file merging, and data reformatting.
