National Health and Nutrition Examination Survey I, 1971-1975: Model Gram File Composition (ICPSR 8070)
Published: Jan 18, 2006
Consists of 3,500 food items with food groups, food codes, alpha-numeric descriptions, and preferred food model codes and gram conversion factors. The Nutrient Composition file is the actual nutrient analysis in 100 gram edible portions of all foods listed in the Model Gram file.
In preparing the data tapes for these collections, the National Center for Health Statistics (NCHS) has removed direct identifiers and characteristics that might lead to identification of data subjects. As an additional precaution, NCHS requires, under section 308(d) of the Public Health Service Act (42 U.S.C. 242m), that data collected by NCHS not be used for any purpose other than statistical analysis and reporting. NCHS further requires that analysts not use the data to learn the identity of any persons or establishments and that the director of NCHS be notified if any identities are inadvertently discovered. ICPSR member institutions and other users ordering data from ICPSR are expected to adhere to these restrictions.
Data in this collection are available only to users at ICPSR member institutions.
