National Health and Nutrition Examination Survey (NHANES)

This site, from the U.S. Centers for Disease Control and Prevention, contains raw data, documentation, and SAS code for the NHANES surveys. Online tutorials and links to other CDC health surveys (health care, immunization, aging, family growth) enrich the content of the site. Some of the data sets are restricted and require approval from NHANES.


Food Surveys Research Group (USDA Agricultural Research Service)

This website contains food and nutrition data from several different databases. What We Eat in America contains survey data on U.S. food and nutrient intake. Food and Nutrient Database for Dietary Studies provides data on 13,000 common foods. MyPyramid Equivalents Database translates foods eaten into equivalent food pyramid groups. Data from all databases can be downloaded in SAS.

National Institutes of Health

Since NIH is the primary U.S. Government agency responsible for medical research, the contents on this site are predominantly related to research, grants, and clinical trials. "Health topics A-Z" links to articles about diseases, treatments, and research results rather than data.


Integrated Health Interview Series

This site from the Minnesota Population Center contains microdata from the U.S. National Health Interview Survey. Users must register (free). The user selects desired variables and years, and the site extracts the customized data and sends notice with downloading information. Data is in fixed-column ascii format. IHIS also supports SAS, SPSS, and Stata with special syntax files.
