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

说明(由申请者提供)：该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，这些数据对于开展关于(1)移民健康和死亡率以及(2)移民如何造成健康和死亡率方面的种族/族裔差异的科学和政策相关研究至关重要。它将把来自国家健康访谈调查(NHIS)八个不同年份的外国出生的受访者，包括以前被NCHS与国家死亡指数(NDI)的记录联系起来的人，与移民统计局(OIS)的记录联系起来，这些记录包含1973至2008年间入境类别、移民合法永久居留(LPR)和入籍状态的数据。如果按年汇总，所产生的关联数据集将包含数十万个病例(包括超过100,000个外国出生的病例)；将包括关于个别受访者的健康、医疗保健覆盖范围和使用情况的信息(以及外国出生的被调查者的入境、LPR和入籍状况以及这些状况发生变化的时间)的信息；将包含关于2006年国家死亡指数的死亡数据的信息，从而能够判断被调查者是否死亡、何时死亡以及死亡原因。该项目还将评估NHIS-OIS匹配的质量，按移民入境、入境类别、LPR和入籍状态估计健康和死亡率差异，并评估鉴于某些匹配的准确性存在不确定性的可能估计范围。这些新关联的健康、死亡率和移民数据将使研究人员能够首次评估美国外国出生人口和众多原籍群体的广泛儿童和成人危险行为以及健康和死亡结果，这些群体按入境状态(未经授权与合法)、合法进入人口按接纳和适应LPR身份分类以及LPR人口按归化状态进行评估。这些关键的描述性信息--以及新数据将催生的分析性研究--将提供移民健康和死亡率的那种详细概况，并刺激必要的开创性研究，以促进对美国种族/民族健康和死亡率差异的起源的科学知识。GO供资机制适合于拟议的项目，因为它将产生有价值的新的科学和与政策相关的健康和死亡数据，将向更大的研究界提供。这里提出的记录联系有可能以适当的成本获得巨大的回报，因为它们利用了已经收集和联系的健康和死亡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受访者那里回溯收集。NHIS-NDI-OIS关联数据的提供将开辟研究移民健康和死亡率的新途径，并有助于解决移民如何促进种族/族裔群体健康差异的重要问题，事实证明，这些差异不可能通过现有的具有全国代表性的数据来解决。 公共卫生相关性：该项目力求为美国生成具有全国代表性的新的大规模公共使用数据，这些数据对于开展关于(1)移民健康和死亡率以及(2)移民如何造成健康和死亡率方面的种族/族裔差异的科学和政策相关研究至关重要。移民正在重塑美国人口，移民健康对理解种族和民族在健康和死亡率方面的差异具有特别重要的影响。这些数据的提供将为研究移民健康和死亡率开辟新的途径，并有助于解决有关移民如何促成种族/族裔群体健康差距的重要问题，事实证明，这些差距不可能通过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.
