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），国家的健康研究基础设施的重要组成部分。在过去的五年里，研究人员创建了IHIS，这是一套来自国家健康访谈调查（NHIS）的统一数据和文件，其中包括从20世纪60年代至今超过400万人的数据。我们建议将数据库扩大三倍，以涵盖其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数据很少用于研究长期变化。原始公共使用文件的结构和调查设计的复杂性使得NHIS难以分析一年多的时间。各年和调查设计期之间的不一致性使得长期时序分析的费用高得令人望而却步。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数据转换为集成格式，并传播了大约2，000个变量。综合信息系统的第二阶段将包括下列相互关联的组成部分：⑴数据整合-将整合变量的数目增加三倍; ⑵数据库扩大-在获得新年份的调查数据和相关死亡率数据后增加这些数据; ⑶数据增强-构建新的变量以简化分析; ⑷文件编制-构建新的样本和变量，包括每个变量在不同时间的可比性; 5）数据访问-加强检索国际HIS数据和文件的网络系统，增加可变搜索和在线制表等新功能; 6）传播-扩大用户支持和外联。NHIS是国宝;没有其他国家的健康调查数据接近主题覆盖的时间跨度和深度。IHIS正开始为美国新一代的健康动态研究提供证据。扩大IHIS数据库与NIH作为国家医学和行为研究管理者的中心使命直接相关：完整的IHIS将使卫生研究人员能够对50年的变革进行比较，并将对公共卫生倡议的长期影响、健康差距、医疗保健的获得、人口老龄化、以及其他与健康相关的话题。公共卫生相关性：这个项目，以扩大综合健康访谈系列（IHIS）是直接相关的中央使命的国家卫生研究院作为医疗和行为研究的管家。完整的IHIS与1963年至2012年的国家健康访谈调查（NHIS）的综合数据和文件，将促进跨时期研究，以改善人口健康，并将导致新的科学和政策相关的研究健康行为和差异，获得和使用医疗保健，人口老龄化，以及国家公共卫生目标的进展。

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.
