NHANES Dietary Web Tutorial

Technical and Software Requirements

To view the tutorial, you will need the following:

In addition, a software license to run SAS and/or SUDAAN is very helpful, though not required.


Allowing pop-up windows

Any of the more recent Netscape, Internet Explorer, and Firefox browsers should run the JavaScript code to produce pop-up windows. However, the security settings on your browser may block the pop-up windows from opening.

This tutorial makes heavy use of pop-up windows. Pop-up windows make it easier for you to access additional information if you want it, and to return to the main page of each module without having to use the browser's Back button.

How to allow pop-up windows


Allowing blocked content to run

The NHANES web tutorial also uses scripting to make its contents interactive.  Microsoft Internet Explorer may be configured to block this content.

Setting your monitor's resolution and adjusting your text size

The CDC website is 800 pixels wide.  Therefore, a monitor resolution of 800x600 pixels is the minimum you should use.  If you use a narrower width resolution, you will have to scroll side to side, as well as up and down.  We recommend a 1024 X 780 resolution for optimal viewing.

You can download the free Adobe Acrobat Reader from Adobe's website at


Installing a Flash Player

All of the tutorial animations are in Flash .SWF format. To view them you will need a Flash Player. However, you do not have to view the animations to complete the tutorial.

Obtaining SAS and SUDAAN

Many tutorial modules contain sample code.  If you wish to run this code on your own, you must have a software license to run SAS and/or SUDAAN on your computer.
