Integrated Health Interview Series Renewal

描述（由申请人提供）：本申请的目标是扩展和丰富综合健康访谈系列（IHIS），这是国家健康研究基础设施的重要组成部分。在过去的五年中，调查人员创建了IHIS，这是一套来自全国健康访谈调查（NHIS）的数据和文件的协调集，其中包括从20世纪60年代到现在的400多万人的数据。我们建议将数据库扩展三倍，以包含剩余的调查补充和变量，以便对美国过去五十年的疾病、残疾、健康行为和医疗保健进行全面分析。NHIS是美国人口健康信息的主要来源，但NHIS数据很少用于研究长期变化。原始公共使用档案的结构和调查设计的复杂性使得NHIS难以分析超过一年的时间。跨年和调查设计期间的不兼容性使得长期时间顺序分析的成本令人望而却步。IHIS通过整合NHIS从1963年到2012年的数据和文件来解决这些问题。在项目的第一阶段，我们开发了工具和基础设施，将整个NHIS数据转换为综合格式，并传播了大约2000个变量。IHIS的第二阶段将包括以下相互关联的组成部分：1)数据整合——将整合变量的数量增加三倍；2)数据库扩展——增加新年份的调查数据和相关死亡率数据；3)数据增强——构建新的变量来简化分析；4)文档——构建新的样本和变量，涵盖每个变量在时间上的可比性；5)数据访问——加强基于网络的IHIS数据和文件检索系统，增加诸如变量搜索和在线制表等新功能；6)传播——扩大用户支持和推广。国家卫生系统是国宝；没有其他国家的健康调查数据在主题覆盖方面按时间顺序接近同样的广度和深度。IHIS正开始为美国新一代充满活力的健康研究解开这一证据。扩展IHIS数据库与NIH作为国家医学和行为研究的管理者的中心任务直接相关：完整的IHIS将使健康研究人员能够对50年来的变革进行比较，并将产生大量关于公共卫生倡议、健康差异、获得医疗保健、人口老龄化和其他健康相关主题的长期影响的新研究。公共卫生相关性：这个扩展综合健康访谈系列（IHIS）的项目与NIH作为国家医学和行为研究的管理者的中心任务直接相关。完整的IHIS，整合了1963-2012年全国健康访谈调查（NHIS）的数据和文件，将促进跨时间研究，以改善人口健康，并将在健康行为和差异、医疗保健的获取和使用、人口老龄化和实现国家公共卫生目标方面产生新的科学和政策相关研究。

DESCRIPTION (provided by applicant): The goal of this application is to expand and enrich the Integrated Health Interview Series (IHIS), a vital component of the nation's health research infrastructure. During the past five years, the investigators created the IHIS, a harmonized set of data and documentation from the National Health Interview Survey (NHIS), with data on more than four million persons from the 1960s to the present. We propose to expand the database threefold to encompass the remaining survey supplements and variables, to allow comprehensive analysis of illness, disability, health behavior, and healthcare over the last fifty years in the United States. The NHIS is the principal source of information on the health of the U.S. population, but NHIS data have rarely been used to study long-term change. The structure of the original public use files and the complexities of the survey design made the NHIS unwieldy for analyzing more than one year. Incompatibilities across years and survey design periods made the cost of long-run chronological analysis prohibitive. IHIS addresses these problems by integrating NHIS data and documentation from 1963 to 2012. In the first phase of the project, we developed the tools and infrastructure to convert the entire body of NHIS data into an integrated format and disseminated approximately 2,000 variables. This second phase of IHIS will consist of the following interrelated components: 1) data integration--triple the number of integrated variables; 2) database expansion--add new years of survey data and linked mortality data as they become available; 3) data enhancement--construct new variables to simplify analysis; 4) documentation--construct for new samples and variables, covering the comparability of each variable across time; 5) data access-- enhance the web-based system for retrieval of IHIS data and documentation, adding new features such as variable search and online tabulation; 6) dissemination--expand user support and outreach. The NHIS is a national treasure; no other country has health survey data approaching the same chronological breadth and depth of subject coverage. IHIS is beginning to unlock this evidence for a new generation of dynamic research on health in the United States. Expanding the IHIS database is directly relevant to the central mission of the NIH as the steward of medical and behavioral research for the nation: the full IHIS will allow health researchers to make comparisons across five decades of transformative change and will result in a substantial body of new research on the long-run impact of public health initiatives, health disparities, access to medical care, population aging, and other health-related topics. PUBLIC HEALTH RELEVANCE: This project to expand the Integrated Health Interview Series (IHIS) is directly relevant to the central mission of the NIH as the steward of medical and behavioral research for the nation. The full IHIS, with integrated data and documentation for the National Health Interview Survey (NHIS) from 1963-2012, will facilitate cross-temporal research to improve population health and will result in new scientific and policy-relevant research into health behavior and disparities, access to and use of medical care, population aging, and progress toward national public health goals.
