Compendium of Dietary Files for Mexican-Influenced Communities v.1™
The DRG file for the Compendium of Dietary Files for Mexican-Influenced Communities v.1 uses information from the Binational Arsenic Exposure Survey (BAsES) dietary survey conducted in partnership with the University of Arizona and the Arizona Cancer Research Center (2009). This 24 hour recall survey was administered to 478 respondents in the US and Mexico and the complete data were available for application to this dietary profile file. BAsES data were the sole source of information used in creating this DRG file and distributional analysis of the data was performed when possible. Details of the methods, calculations, and specific results can be found in the extensive documentation accompanying the file. Values for children were not extrapolated from this data; therefore, children’s intake cannot be assessed using this dietary file.
This compendia and dietary file is unique from other DRG compendia, like the Compendium of Alaska Traditional and Subsistence Dietary Files, because it draws from a sole source of information instead of using several information sources. The standards of data relevance, representativeness, quantifiable characteristics of the data, and transparency still apply to this data; but since a complete data set possessing these qualities was available, less emphasis needed to be placed on ensuring that each individual information point met these criteria.
The food list and consumption parameters (age and seasonally dependent probability of eating and daily intake values) reflect the data collected in the BAsES survey. It is recognized that several different regions/population groups might also experience a Mexican influenced diet, and yet demonstrate very different consumption habits (different foods, frequencies of eating them, etc.). For assessments which are intended to reflect a specific Mexican influenced diet other than this one, modifications to this dietary profile file may be appropriate or a complete new DRG file might be necessary.
Scientists from the University of Arizona , who are familiar with the data and population, provided expert advice to LifeLine scientists throughout the process of file creation and reviewed the resulting DRG file for relevance and accuracy. The DRG software and the resulting Compendium of Dietary Files for Mexican-Influenced Communities have an important place in the public health policy discussion and establish a capability to better describe dietary profiles for a Mexican influenced population and to keep these profiles current as dietary patterns change over time.
