The 2016 versions of the ASA24 system require high-speed internet and are accessible using desktops, laptops, tablets, and smartphones. The user interface is written in HTML5. Unlike previous versions, the 2016 versions enable the ASA24 system to load on commonly used web browsers without downloading Microsoft Silverlight or other plug-ins.

Researchers were required to switch to ASA24-2016 or ASA24-2016 in March of 2017 because the Silverlight plug-in required for earlier versions is no longer supported by most commonly used web browsers. There are currently no funds to update ASA24-Kids-2014. Researchers should use ASA24-2016 instead.

For Researchers using earlier versions of the ASA24 system who have switched mid-study to a 2016 version:

  • The underlying nutrient and food group databases for versions prior to ASA24-2016 are not directly comparable (see a table comparing the features of all versions of ASA24). SAS code is available to update analytic files from older versions to a comparable food group database as ASA24-2016. ASA24-Canada-2014 and ASA24-Canada-2016 use the same nutrient databases but the 2014 version, unlike the 2016 version, does not include food groups. It is not possible to rerun ASA24-2011, ASA24-2014, or ASA24-Canada-2014 Respondent data using ASA24-2016 or ASA24-Canada-2016.
