Compendium of Dietary Files for the American Southwest™

The two population groups which are described in the DRG™ files each have different demographic/ethnic and cultural identities. They are affected in different ways by health disparities, cultural food choices, and unique lifestyle patterns. This compendium of files does not claim to be comprehensive as there are many other communities which would benefit from characterization using LifeLine tools. The two groups whose dietary profiles are described by the DRG files (respectively) are:

  • Southwest 1: The DRG file for “Southwest 1” uses information from publications from the Navajo Health and Nutrition Survey (NHNS) conducted in 1991-1992. Study design and population description is available in the study by Ballew et al and White et al. There are three age categories which were considered for this dietary file. Age categories from the NHNS include 12-19y, considered within the 13-19y DRG age group; 20-39y and 40-59y, considered within the 20-60y DRG age group; and 60+, considered within the 61+y DRG age group. No seasonal information is considered in this DRG file as this information is not published. Values for children younger than 13y were not extrapolated from this data. Children’s intake was not considered and cannot be assessed using this dietary file.
  • Southwest 2: The DRG file for “Southwest 2” uses information from dietary studies conducted with the Apache in the White Mountains of Arizona. The purpose of the studies which were used to create the DRG™ file were to determine nutrient composition of several commonly consumed foods and to develop a quantitative food frequency questionnaire for this population. Details of the studies can be found in the two studies by Sharma et al. The data which was available for this population pertained only to adults therefore; all available information was applied to the two adult categories (20-60y and 61+y) in LifeLine™ software. No seasonal information is considered in this DRG file as this information is not available in the published literature. Values for children younger than 19y were not extrapolated from this data. Children’s intake was not considered and cannot be assessed using this dietary file.
