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 updated BIX data file contains bioimpedance spectroscopy (BIS) multi-frequency data on resistance, reactance, extracellular fluid, intracellular fluid, total body water, and body composition for individuals 8-49 years of age. There are differences in variable counts between this data release and the previous release, which contained only the resistance and reactance frequency data. Differences in the variable counts and file content are described in the Data Processing and Editing section of the documentation.

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.
NHANES Web Tutorial - Preparing an Analytic Dataset Course Now Features Stata
A Stata track for the Preparing an Analytic Dataset course of the Continuous NHANES Web Tutorial is now on-line. Given the increasing number of Stata users, the NHANES tutorial team added a Stata track to the course's SUDAAN and SAS survey procedures tracks. The Stata track of Preparing an Analytic Dataset course provides instructions on importing SAS .xpt files to Stata, appending and merging data files, cleaning and recoding variables, formatting and labeling variables, and saving a Stata dataset.

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.

- 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.

- To meet the growing demands of NHANES data users, a two more web-based tutorial were developed to promote and facilitate broader and more proficient use of NHANES II and NHANES I data. These tutorials is intended to serve as:
- A step-by-step course on NHANES II and NHANES I data retrieval and analysis for new users.
- A self-learning tool for novice and infrequent users to supplement their knowledge of the NHANES II and NHANES I datasets.
- The NHANES II and NHANES I tutorials, each consisting of courses orienting the user to the survey, preparing an analytic dataset, and survey design factors, are now available on the NHANES website. This tutorial supplements the Continuous NHANES and the NHANES III tutorials. While Continuing professional education credit is available for the Continuous NHANES Web Tutorial, it is not available for the NHANES III, NHANES II, or NHANES I Web Tutorial.

Special Release
- NHANES Web-based Tutorial
- To meet the growing demands of NHANES data users, a web-based tutorial was developed to promote and facilitate broader and more proficient use of NHANES data. The tutorial is intended to serve as:
- A step-by-step course on NHANES data retrieval and analysis for new users.
- A self-learning tool for novice and infrequent users to supplement their knowledge of the NHANES database and the analysis techniques required to properly analyze this complex dataset.
- A reference for experienced researchers highlighting NHANES analytic nuances and sample program code.
- The first phase of the tutorial is now accessible via the NHANES home page. Some modules/sections are still incomplete, but will be posted on the NHANES website as soon as they are complete. The targeted completion date for the entire tutorial is January 2007.
