GENERATING LINKED NCHS AND OIS DATA FOR IMMIGRANT HEALTH AND MORTALITY RESEARCH

描述（由申请人提供）：本项目旨在为美国生成新的具有全国代表性的大规模公共使用数据，这些数据对于开展以下科学和政策相关研究至关重要：(1)移民健康和死亡率；(2)移民如何导致健康和死亡率方面的种族/民族差异。它将把来自全国健康访谈调查（NHIS）的8个不同年份的外国出生受访者，包括以前由全国健康访谈调查与国家死亡指数（NDI）记录联系起来的人，与移民统计局（OIS）记录联系起来，其中载有1973年至2008年入境类别、移民合法永久居留权（LPR）和入籍身份的数据。当跨年汇总时，产生的关联数据集将包含数十万个病例（包括超过10万名外国出生的病例）；将包括有关个人答复者的健康、医疗保健覆盖面和利用情况的信息（以及关于外国出生类别的入境、永久居住权和入籍身份以及这些身份变化的时间）；并将包含截至2006年全国死亡指数的死亡率数据信息，从而能够判断回答者是否死亡、何时死亡以及死因。该项目还将评估国家卫生信息系统- ois匹配的质量，估计按移民入境、入境类别、最低居住年限和入籍身份划分的健康和死亡率差异，并在某些匹配的准确性不确定的情况下评估可能的估计范围。这些新的健康、死亡率和移民数据将使研究人员第一次能够根据入境身份（未经授权与合法）评估美国外国出生人口和众多国籍群体的儿童和成人风险行为、健康和死亡率结果，根据入境和调整LPR身份的合法入境人口，以及根据入籍身份评估LPR人口。这些关键的描述性信息——连同新数据将产生的分析性研究——将提供移民健康和死亡率的详细概况，并刺激必要的开创性研究，以推进有关美国种族/民族健康和死亡率差异起源的科学知识。GO资助机制适合拟议的项目，因为它将产生宝贵的新的科学和政策相关的健康和死亡率数据，这些数据将提供给更大的研究界。这里所提议的记录联系有可能以低廉的代价获得巨大的回报，因为它们利用了已经收集和联系起来的健康和死亡率数据以及关于移民和入籍状况的详细行政信息，而这些信息很难以准确和廉价的方式从答复者那里回顾性地收集。国家健康信息系统-国家健康信息系统- ois相关数据的提供将为移民健康和死亡率的研究开辟新的途径，并有助于解决移民如何导致种族/族裔群体健康差异的重要问题，这些问题已被证明无法用现有的具有全国代表性的数据来解决。

DESCRIPTION (provided by applicant): This project seeks to generate new large-scale nationally representative public-use data for the United States that are crucial for conducting scientific and policy-relevant research on (1) immigrant health and mortality and (2) how immigration contributes to racial/ethnic disparities in health and mortality. It will link the foreign-born respondents from eight different years of the National Health Interview Survey (NHIS), including persons who have previously been linked by NCHS to records from the National Death Index (NDI), to Office of Immigration Statistics (OIS) records containing data on class of admission and immigrant legal permanent residence (LPR) and naturalization status from 1973 to 2008. When pooled across years, the resulting linked data set will contain hundreds of thousands of cases (including over 100,000 foreign born); will include information about individual respondents' health, health care coverage and utilization (and for the foreign born class of admission, LPR and naturalization statuses and the timing of changes in these statuses); and will contain information on mortality data from the National Death Index through 2006, making it possible to tell whether and when a respondent died as well as cause of death. The project will also assess the quality of the NHIS-OIS matches, estimate health and mortality differentials by immigrant entry, class of admission, LPR and naturalization statuses, and assess the likely range of estimates given uncertainty in the accuracy of some of the matches. These newly linked health, mortality and immigration data will enable researchers for the first time to assess a wide array of child and adult risk behaviors and health and mortality outcomes for the U.S. foreign-born population and numerous national-origin groups by entry status (unauthorized versus legal), the legally entering population by class of admission and adjustment to LPR status, and for the LPR population by naturalization status. Such critical descriptive information - together with the analytical research the new data will spawn - will provide the kind of detailed profile of immigrant health and mortality and stimulate the kinds of pathbreaking research necessary for advancing scientific knowledge about the origins of U.S. racial/ethnic health and mortality disparities. The GO funding mechanism is appropriate for the proposed project because it will produce valuable new scientific and policy-relevant health and mortality data that will be made available to the larger research community. Record linkages such as those proposed here have the potential for enormous pay-off at modest cost since they take advantage of already-collected and linked health and mortality data and detailed administrative information about immigration and naturalization status that is difficult to collect retrospectively from respondents in an accurate and inexpensive manner. The availability of the NHIS-NDI-OIS linked data will open up new avenues of research on both immigrant health and mortality and help to address important questions about how immigration contributes to racial/ethnic group health disparities that have proven impossible to address with existing nationally-representative data. PUBLIC HEALTH RELEVANCE: This project seeks to generate new large-scale nationally representative public-use data for the United States that are crucial for conducting scientific and policy-relevant research on (1) immigrant health and mortality and (2) how immigration contributes to racial/ethnic disparities in health and mortality. Immigration is reshaping the U.S. population, and immigrant health holds particularly important implications for understanding racial and ethnic disparities in health and mortality. The availability of the data will open up new avenues of research on both immigrant health and mortality and help to address important questions about how immigration contributes to racial/ethnic group health disparities that have proven impossible to address with existing nationally-representative data.
