What’s New at the NCHS Research Data Center

NCHS Research Data Center website. The following updates have been made:
  •  Linking Up with the RDC
 We have developed our very own blog to help foster a research community among Research Data Center staff and users. Monthly features will be published from RDC staff members, researchers, NCHS data system representatives, and others! Please check out our blog and email us if you’d like to contribute!
  • New Confidentiality Orientation
 Changes have been made to our confidentiality policies. These new policies are applicable to all new proposals. Be sure to review the new policies as you write your RDC proposal.
  • First Annual Atlanta Census Research Data Center Conference
The Atlanta Census Research Data Center will be hosting their first annual conference at the University of Georgia, in Athens, on October 18th and 19th. This conference will create an opportunity to learn about the research being done at the new location. Students can register for free!
  •  Northwest Census Research Data Center
In a partnership with the University of Washington, a new research data center is now open in Seattle, Washington. Available at this location are restricted demographic, economic, public health, and linked business and household data.  

New Data Available through the RDC
  • National Health and Nutrition Examination Survey (NHANES)
    •  Hemagglutination inhibition antibody titers to influenza A/ H1N1 viruses
      •  Among a sample of participants of all ages, the antibody testing of stored sera specimens from NHANES 2007–2008 was conducted to determine population levels of pre-pandemic cross reactive antibody to the 2009 pandemic influenza A/H1N1 virus and related influenza A/H1N1 viruses prior to the spread of the novel 2009 H1N1 virus. This data release contains the hemagglutination inhibition assay titers to 2009 H1N1 and two past H1N1 influenza virus. 
  •  National Health Interview Survey (NHIS)
    •  Preliminary Quarterly Microdata Files
      •  A preliminary microdata file for the January–March 2012 National Health Interview Survey (NHIS) is now available through the National Center for Health Statistics (NCHS) Research Data Center (RDC). NHIS data users can analyze this file without having to wait for the final annual NHIS microdata files to be released (in about June following the end of the data collection year).
  • Longitudinal Studies of Aging (LSOA)
    • LSOA II Linked Mortality Update
      • NCHS has updated the mortality linkage of the Second Longitudinal Study of Aging (LSOA II) to death certificate data found in the National Death Index (NDI). The updated LSOA II Linked Mortality File provides mortality follow-up data from the date of SOA II interview (1994-1996) through December 31, 2006. There are two versions of the LSOA II Linked Mortality File: a public-use file that includes a limited set of mortality variables for LSOA II participants and a restricted-use file that includes more detailed mortality information.
