Data Release - Limited Access Data

• California - Demographic Variables & Sample Weights (CDEMO_AD 1999-2000)

Updated Data

In the updated DXXFRX_H file the FRAX scores for participants with missing femur neck BMD values were set as missing. This was done because we did not have sufficient information to define secondary osteoporosis, which is one of the risk factors used in FRAX. However, if femur neck BMD is available, then it is not necessary to include secondary osteoporosis in the FRAX model.

• Dual-Energy X-ray Absorptiometry - FRAX Score (DXXFRX_H 2013-2014)

Withdrawn Data

The urine VOC metabolites dataset from NHANES 2005-2006 has been withdrawn so it can be updated to correct for systematic bias to several analytes. An updated and unbiased dataset will soon be released for urine VOC metabolites from NHANES 2005-2006.

In 1999-2000, the mean TST results and PPD-B TST results of up to three readers were published for each survey participant. The initial release of the 2011-2012 data contained a single TST result for each survey participant. The updated 2011-2012 release contains the mean TST results of up to three readers for each survey participant. In both the 1999-2000 and updated 2011-2012 datasets, if only one TST result was recorded for a survey participant, the single result is published. PPD-B TST tests were not included in the 2011-2012 study.

The original pooled-sample weight created for the following laboratory files released in July 2013 did not accurately take into account the new sample design for this NHANES survey cycle and it was not correctly stratified to the U.S. population total. The new released files contain the corrected sample weight (WTSMSMPA).The corrected sample weight was created so that analyses using race and Hispanic origin would be comparable to the three groups used in NHANES 2005-2006 (non-Hispanic white, non-Hispanic black and Mexican-American). Therefore, analyses of the data for ”Total Hispanics” is not appropriate. No changes or corrections were made to the lab analyte data in this new release. Any analyses of the data using the old public use data file should be repeated using the corrected sample weight on this new file.

Tutorials

• NHANES Physical Activity and Cardiovascular Fitness Data Tutorial
  NHANES has released the first course of the NHANES Physical Activity and Cardiovascular Fitness Data Tutorial. The NHANES physical activity and cardiovascular fitness data consist of study participant information obtained through the physical activity questionnaire (PAQ), the cardiovascular fitness examination (CVX), and the physical activity monitor examination (PAX). These data provide a snapshot of physical activity and cardiovascular fitness for the U.S. population. This tutorial simulates a real life experience of how to conduct an analytical project from beginning to end, with a step-by-step logical flow through typical analytic procedures. Relevant information on physical activity and cardiovascular fitness data, nuances, tips, explanations for SAS or SUDAAN programs, downloadable sample program code, and analytical guidance are organized and integrated into different modules and tasks to facilitate this learning process.
• NHANES-CMS Linked Data Tutorial
  NHANES has released the first two courses of the NHANES-CMS Linked Data Tutorial. NHANES-CMS linked data is created by linking NHANES survey participants with claims records collected from Center for Medicare and Medicaid Services (CMS). Linkage of the NHANES survey participants with the CMS data provides the opportunity to study changes in health status, health care utilization and expenditures in the elderly, disabled, and other U.S. populations. This tutorial walks you through the steps for conducting an analytic project using the continuous NHANES-CMS linked data, with examples of common analytic applications and procedures.

  Urinary NNAL has been reported  to NHANES with more than one LOD. The nominal LOD is 0.0006 ng/mL, and that is for normal sample size 5 mL. When the sample volume is less than 5 mL, the LOD for that sample will be different from 0.0006. Therefore, there are more than one LOD for NNAL in NHANES 2007-2008  and 2009-2010 data releases. However, the laboratory has decided to use only one LOD for NNAL. All samples reported to NHANES with LODs other than the nominal LOD were changed from non-detect to missing.

  NCHS recently learned that analytical standards used since 1999 and used for several metabolites were of insufficient purity. After further investigation, it was determined that a correction factor needs to be applied to each value for the 5 metabolites. These metabolites and the specific correction factor for each are as follows:  Mono-ethyl phthalate (URXMEP), 0.66; Mono-benzyl phthalate (URXMZP), 0.72; Mono-n-octyl phthalate (URXMOP), 1.68; Mono-isononyl phthalate (URXMNP), 1.54; and Mono-cyclohexyl phthalate (URXMCP), 2.01. The correction factor should be applied to each analyte for NHANES survey periods 1999-2000, 2001-2002, 2003-2004, 2005-2006, and 2007-2008 results.

A similar calibration bias resulted in withdrawal of several chemical results for the 2 survey periods and described in documentation notes for the Urinary Priority Pesticides and Organophosphate Pesticides files (Lab26PP, L26PP_B).

Announcement

The final course of the NHANES Dietary Tutorial is published online. The dietary tutorial is a major supplement to the existing NHANES Web Tutorial and provides information and instructions specific to dietary data and analyses. The first course, Dietary Data Orientation, gives an overview of the dietary data, provides roadmaps to the complex data structure and contents, and orients users to the NHANES website and its resources for dietary data analysis. The second course, Preparing a Dietary Analytic Dataset, provides step-by-step instruction from locating and downloading variables, to merging and appending, formatting, and saving datasets. Basic Dietary Analyses demonstrates how to perform some of the most frequently requested analyses of NHANES dietary data. The latest addition, Advanced Dietary Analyses, describes techniques for estimating usual intake of dietary and supplement intake, how dietary intakes vary among individuals, and how individual intakes relate to other factors.

The purpose of this note is to inform users of serum 25-hydroxyvitamin D (25(OH)D) data from NHANES about two issues that should be addressed when analyzing these data. First, users are cautioned about making direct comparisons between serum 25-hydroxyvitamin D measurements from NHANES 2000-2006 (i.e., publicly released data for 2001-2006 and controlled-access data for 2000) and measurements obtained in NHANES III (1988-1994). NHANES III 25(OH)D data must be adjusted in order to make a valid comparison to the 2000-2006 NHANES survey years. Second, data users should also be aware that the 25(OH)D data from the 2000-2006 NHANES were most likely affected by drifts in the assay performance over time.

NHANES Dietary Tutorial - Basic Dietary Analyses Available Now

The three courses of the NHANES Dietary Tutorial are published online. The dietary tutorial is a major supplement to the existing NHANES Web Tutorial and provides information and instructions specific to dietary data and analyses. The first course, Dietary Data Orientation, gives an overview of the dietary data, provides roadmaps to the complex data structure and contents, and orients users to the NHANES website and its resources for dietary data analysis. The second course, Preparing a Dietary Analytic Dataset, provides step-by-step instruction from locating and downloading variables, to merging and appending, formatting, and saving datasets. The latest addition, Basic Dietary Analyses, demonstrates how to perform some of the most frequently requested analyses of NHANES dietary data. Additional modules on advanced dietary analyses will be released later in the year.

Now Available: Documentation for Datasets Available in the Research Data Center (RDC)

In an effort to help analysts determine if NHANES datasets contain variables relevant to their analyses before submitting an application to use the RDC, documentation for several limited access datasets is now available through the NHANES website. Currently, documentation for the 1999-2004 Diagnostic Interview Schedule for Children (DISC), 1999-2004 Los Angeles Demographic, and 1999-2004 Youth Conduct Disorder datasets is available. Documentation for more limited access datasets will be released in upcoming months.

 

To locate the limited access dataset documentation, go to a survey data page, and click the Limited Access link. Direct links to the pages have also been provided below.

Updated

• Demographic (2005-2006)
  The Demographics public release file includes information that was collected using the Sample Person and Family Demographics question­naires. An educational attainment variable (DMDEDUC3) was added to this updated Demographics file to provide consistency with the NHANES 1999-2004 Demographics files. An earlier version of the educational attainment variable (DMDEDUC1) has been removed from the 2005-2006 file. 
• Demographic (2003-2004)
• Demographic (2001-2002)
• Demographic (1999-2000)
  EDUCATIONAL ATTAINMENT: Five educational attainment variables are included the Demographics File. Three of the education variables target survey participants. Two other education variables provide information about the educational attainment of the household reference person (DMDHREDU) and the household reference person’s spouse (DMDHSEDU), when applicable. A brief description of the three survey participant educational attainment variables follows.
  
  The Demographics File contains two variables that provide additional information on the educational attainment level of survey participants. Educational attainment information for persons 6 through 19 years of age is included in DMDEDUC3. Detailed educational attainment information for adults who are 20 years of age and over is reported in DMDEDUC2.
  
  In addition, DMDEDUC is a three-category variable that groups ALL survey participants 6 years of age and over into one of three educational attainment groups: 1) less than high school education attainment, 2) high school graduate (has a high school diploma or high school equivalency diploma such as a General Educational Development/GED), or 3) has more than a high school education. DMDEDUC collapses categories from the other two education variables, and is retained in the file for the convenience of DHANES tutorial users. 
• Lab 28 Dioxins (LAB28POC 1999-2000)
  Due to a miss-assignment of the concentration of purchased standard material, the data for beta-hexachlorcyclohexane serum levels in the Lab 28 Dioxins data file (LAB28POC) for the period 1999-2000 should be multiplied by 0.644. 
• Lab 26 Urinary Organophosphate Insecticides: Diakyl Phosphate Metabolites (26OPD_C_2003-2004) has been temporarily withdrawn from release. Some values were incorrectly reported for the variables URXOP1-URXOP6. A corrected dataset and documentation will be posted.
