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.

- Serum Cotinine and Urinary Total NNAL (COTNAL_E 2007-2008)
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.

The pentachlorophenol (URXPCP) and 2,4-dichlorophenol (URXDCB) results for the 2 survey periods (1999-2000 and 2001-2002) were affected by an unacceptable calibration bias and these results are withdrawn. 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.
