Navigate NHANES Website
Purpose:
In order to analyze NHANES environmental chemical data, it is important to understand how the NHANES website is organized. The NHANES website includes not only NHANES environmental chemical data but also related NHANES data, survey and laboratory descriptions and other analytic aids for researchers. This module provides users with an orientation to the overall NHANES website. Much of the material presented in this module can also be found in the Continuous NHANES tutorial.
Task 1: Navigate the NHANES Homepage
By getting acquainted with the NHANES homepage, you will gain an appreciation for the number and diversity of materials available through the NHANES website. Users will learn a general layout of the NHANES homepage.
Task 2: Find Datasets on the NHANES Website
All publicly available data and related documentation, including those for environmental chemical data, are released and updated on the NHANES website. Information on accessing non-publicly released data are also available on the NHANES website. This task will describe the difference between public and non-public use data and provide guidance on where these data are located.

- How to Find Publically Released Datasets and Information on Non-publicly Released Datasets
Task 3: Find Survey Background Information
Reviewing the NHANES survey background information is an important step as you determine the scope of your analysis and which variables to include. This task will inform the user general information about the content of NHANES and description of its survey components.
Task 4: Find the Analytic and Reporting Guidelines
The Analytic and Reporting Guidelines should be considered when using NHANES data for analysis and publications. The guidelines provide users a framework for producing estimates that conform to the analytic design of the survey. This task will describe how to locate these Guidelines.

- How to Find the Analytic and Reporting Guidelines
Task 5: Use the What’s New Page
The What’s New page is an important resource for staying updated with current information about the survey, including newly released data files. It is an important link to refer to on a periodic basis. This task will describe the content and location of the What's New page.
Task 6: Review the Frequently Asked Questions (FAQ) Page
The FAQs will help you with common questions about NHANES. This task will describe how to locate answers to frequently asked questions about the environmental chemical data.
- Key Concepts about Using the Frequently Asked Questions Page
- How to Use the Frequently Asked Questions
Task 7: Find Important NHANES Citations
NHANES researchers are often asked to cite the data source for their research proposals and related publications. This task will provide the standard citation that can be used to reference NHANES data or protocols.
Task 8: Identify How to Get Help
There are two additional resources available for getting help: the NCHS email query and the NHANES listserv. This task will provide instructions on how to use the additional help resources.
