The Second National Health and Nutrition Examination Survey (NHANES II) Linked Mortality File: 2005 Release

NCHS has completed a mortality update for the second National Health and Nutrition Examination Survey (NHANES II) Mortality Study (1992), which includes new record linkages of adult NHANES II participants with death records from the National Death Index (NDI). This new resource allows researchers the opportunity to conduct a vast array of outcome studies designed to investigate the associations of a wide variety of health and risk factors with mortality. This updated mortality file is comprehensive in design so that it contains death information for deaths ascertained as part of the 1992 NHANES II Mortality Study as well as new deaths identified with the new probabilistic linkage with the NDI through December 31, 2000.

Due to confidentiality requirements, access to this file is available only through the NCHS Research Data Center (RDC). The NCHS RDC offers on-site and remote access capabilities. Interested researchers must submit an application to the NCHS RDC. For more information on the RDC application process, please visit http://www.cdc.gov/nchs/r&d/rdc.htm.
