Public-Use Linked Mortality Files

NCHS has linked data from various surveys with death certificate records from the National Death Index (NDI). Linkage of the NCHS survey participant data with the NDI mortality data provides the opportunity to conduct a vast array of outcome studies designed to investigate the association of a wide variety of health factors with mortality. The Linked Mortality Files (LMF) have been updated with mortality follow-up data through December 31, 2019. Public-use Linked Mortality Files (LMF) are available for 1986-2018 NHIS, 1999-2018 NHANES, and NHANES III. The files include a limited set of mortality variables for adult participants only. The public-use versions of the NCHS Linked Mortality Files were subjected to data perturbation techniques to reduce the risk of participant re-identification. For select records, synthetic data were substituted for follow-up time or underlying cause of death. Information regarding vital status was not perturbed.

美国国家卫生统计中心（National Center for Health Statistics, NCHS）已将多类调查数据与国家死亡索引（National Death Index, NDI）的死亡证明记录完成关联匹配。将NCHS调查参与者数据与NDI死亡登记数据进行关联，可为开展一系列旨在探究各类健康因素与死亡风险关联的结局研究提供支撑条件。关联死亡档案（Linked Mortality Files, LMF）已更新至2019年12月31日的死亡随访数据集。面向公众开放的关联死亡档案覆盖1986-2018年全国健康访谈调查（National Health Interview Survey, NHIS）、1999-2018年全国健康与营养检查调查（National Health and Nutrition Examination Survey, NHANES）以及NHANES III的调研数据。该数据集仅收录成年参与者的有限死亡相关变量。NCHS关联死亡档案的公开版本采用了数据扰动技术，以降低参与者身份被重新识别的风险。针对部分记录，研究人员使用合成数据替代了随访时长或根本死亡原因。但有关生存状态的信息未进行任何扰动处理。

背景概述

该数据集由NCHS创建，通过链接调查数据与死亡记录，支持研究健康因素与死亡率的关系，覆盖1986-2018年多个国家健康调查的成年参与者。数据集采用数据扰动技术保护隐私，对部分记录的随访时间或死因进行合成替换，但生命状态信息保持原样。
