Integrated Health Interview Series Renewal

描述(由申请人提供)：本申请的目标是扩大和丰富综合健康访谈系列(IHIS)，这是国家卫生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，这是一套统一的数据和文件，来自国家健康访谈调查(NHIS)，其中包含从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大三倍，以涵盖剩余的调查补充和变量，以便对美国过去50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数据很少被用来研究长期变化。原始公共使用文件的结构和调查设计的复杂性使得NHIS在一年多的时间里难以分析。不同年份和调查设计期的不兼容使得长期年表分析的成本过高。IHIS通过整合1963年至2012年的NHIS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2,000个变量。综合信息系统第二阶段将由以下相互关联的部分组成：1)数据整合--综合变量的数量增加两倍；2)数据库扩展--增加新的年份调查数据和现有的相关死亡率数据；3)数据增强--构造新的变量以简化分析；4)文件--为新样本和变量构建文件，涵盖每一变量在不同时间的可比性；5)数据访问--加强网上系统检索综合信息系统的数据和文件，增加新的功能，如变量搜索和在线制表；6)传播--扩大用户支持和外联。国家健康保险制度是一个国宝；没有其他国家的健康调查数据达到同样的主题覆盖广度和深度。IHIS开始为美国新一代关于健康的动态研究揭开这一证据的面纱。扩展iHIS数据库与NIH作为国家医学和行为研究管理者的核心使命直接相关：完整的iHIS将允许卫生研究人员对50年来的变革性变化进行比较，并将产生大量关于公共卫生倡议的长期影响、健康差距、获得医疗保健的机会、人口老龄化和其他与健康相关的主题的新研究。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管理者的核心使命直接相关。完整的信息系统包括1963-2012年全国健康访谈调查(NHIS)的综合数据和文件，将促进跨期研究，以改善人口健康，并将导致对健康行为和差异、获得和使用医疗保健的机会和使用、人口老龄化以及实现国家公共卫生目标的进展进行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.
