ASA24-2014, 2012, and 2011, all versions

Researchers can no longer register new studies to use ASA24-2014, ASA24-Canada-2014 and ASA24-2011; however, all of these versions of the ASA24® system are available for data collection until March 2017. All ongoing studies will be required to update to the 2016 versions of the ASA24 system by March 2017.

Researchers can still register to use ASA24-Kids 2012, however, after March 2017 all ongoing studies will be required to update to the 2016 versions of the ASA24. There is currently no funding to develop an updated version of ASA24-Kids.

ASA24-2014, ASA24-Canada-2014, ASA24-Kids-2012, and ASA24-2011:

  • Use version 4.1 of USDA's Food and Nutrient Database for Dietary Studies (FNDDS)External Web Site Policy or the Canadian Nutrient File (CNF) 2015 to estimate nutrient intakes;
  • Use version 2.0 of the USDA's MyPyramid Equivalents Database* (MPED)External Web Site Policy and the USDA's Center for Nutrition Policy and Promotion's MPED Addendum to estimate intakes of dietary guidance-based food groups (nutritionists on the ASA24 team imputed values for nine food codes for which MyPyramid Equivalents were not assigned by USDA);
  • Include optional modules to query the location of meals, with whom meals were eaten, and television and computer use during meals;
  • Include an optional module to query supplement intakes based on supplements reported in the 2007-2008 National Health and Nutrition Examination Survey (NHANES) for U.S. versions or the Licensed Natural Product Database & National Health and Nutrition Examination Survey (NHANES) Dietary Supplements Database 2007-2008 for the Canadian version; and
  • Allow participants to complete food recalls in English or Spanish (ASA24-Canada-2014 is only available in English).

*Not available for ASA24-Canada-2014

The ASA24-2014 and ASA24-Canada-2014 versions (not ASA24-2011) also include options to:

  • Query the source of each food consumed to provide information on where foods are obtained (i.e., grocery store, farmer's market, vending machine, etc.);
  • Query different 24-hour time frames: midnight to midnight of the previous day or the past 24-hours starting with the Respondent's first login; and
  • Require participants to complete recalls in one sitting with breaks of no longer than 30 minutes.

Note to users of the ASA24-2011 and ASA24-Kids-2012: Data collected using ASA24-2011 or ASA24-Kids-2012 and ASA24-2014 are comparable as both use the same nutrient and food group databases. Most of the changes between the ASA24-2011 and 2014 versions were related to modifications of the user interface.
