Due to
confidentiality requirements, the NHANES III Linked
MortalityRestricted-use data are only
accessible through the
NCHS Research Data Center (RDC).
All interested researchers
must submit a research proposal to the RDC. The RDC offers both on-site and
remote user access. Approved researchers will be able to analyze data from
the NHANES III
Restricted-useLinked MortalityFile which contains information on NHANES III
participant eligibility status, vital status, date of death, age at death,
and underlying and contributing causes of death. Additional death
certificate data are available by special
request. Requests for access to special request variables will
require additional justification in the researcher’s RDC proposal. The
NHANES III Linked Mortality Restricted-use
File does not contain perturbed
data.
