BACKGROUND:

The CSFII 1989-91, conducted as three separate 1-year surveys in 1989, 1990, and 1991, was designed to measure what Americans eat and drink. Information from the surveys is used to develop nutrition education programs, to assess dietary changes associated with participation in food programs, to develop food fortification and enrichment policies, to monitor the safety of the food supply, and to assess demand for agricultural products and marketing facilities.

The DHKS 1989-91, conducted as a telephone follow-up to the CSFII 1989-91, was designed to improve our understanding of factors that affect food choices and to obtain information on people's knowledge and attitudes about the Dietary Guidelines for Americans. Together, the CSFII and the DHKS provided the first opportunity on a national scale to link an individual's knowledge and attitudes (from the DHKS) to his or her dietary behavior as indicated by food intake information collected from the same individual in the CSFII.
 

METHODS:

Individuals who took part in the CSFII were asked to provide 3 consecutive days of dietary data. The first day's data were collected in a personal in-home interview using a 1-day dietary recall. The second and third days' data were collected using a self-administered 2-day dietary record. Individuals who were identified as the main meal planners/preparers in the CSFII were contacted by telephone, if possible, about 6 weeks after collection of the dietary data and were asked to answer a series of questions about knowledge and attitudes toward diet, health, and food safety. 
 

AVAILABILITY:

CSFII 1989-91 data and survey reports are available from the NTIS website. Complete 3-year data are available on CD-ROM ; single-year data for each survey year are also available on data tape. 

CD-ROM:

• 1989-91 Continuing Survey of Food Intakes by Individuals and 1989-91 Diet and Health Knowledge Survey on CD-ROM. NTIS accession number: PB96-501747.
  

This CD-ROM contains 1-day dietary intake data for 15,192 individuals, 3-day dietary intake data for 11,912 individuals, and diet and health information from 5,730 individuals identified as main meal planners/preparers. Also on the CD-ROM is a user interface called the Statistical Export and Tabulation System (SETS). SETS provides a convenient format for PC users to browse survey documentation and files, build record subsets, create tables, and export data to other software systems for analysis.
