The user interface for all 2016 versions of ASA24, including ASA24-Canada-2016 and ASA24-Australia-2016, employs a responsive design, meaning that these latest versions of the ASA24 system can be used on smartphones and tablets, in addition to laptops and desktops. This allows a broad range of participants to enter dietary intake data at any time and from any location with internet service.
Since the release of ASA24-2016 in March 2016, >1300 studies registered to use ASA24, and 318,000 recalls or records were collected through August 2017.
With the release of the newest U.S. and Canadian versions of ASA24-2018, new studies can no longer be registered using the U.S. or Canadian versions of ASA24-2016. Researchers currently collecting data using the U.S. version of ASA24-2016 will need to transition these studies to ASA24-2018 by January 2020. Researchers currently collecting data using ASA24-Canada-2016 will need to transition these studies to ASA24-Canada-2018 by April 2020.
The following are features of the 2016 versions of ASA24 that were new when it was released and are still part of ASA24-2018:
- The user interface has been rewritten in HTML5. This will enable the ASA24 system to load on all popular web browsers without downloading Microsoft Silverlight, the plug-in required for previous versions of the ASA24® system.
- Respondents can now complete single- or multi-day food records (also known as diaries) in addition to 24-hour recalls. This expands the types of studies and applications for which Researchers can use the ASA24 system;
- Researchers collecting 24-hour recalls or food records using the U.S. version of the ASA24 can select an optional module to allow for the generation of a Respondent Nutrition Report that provides information about how daily intakes compare to U.S. dietary guidance and nutrient requirements. If this optional module is turned on for food records, the Researcher must provide the report to the Respondent after obtaining it from the Researcher website. For 24-hour recalls, if the optional module has been turned on, the Respondent will be able to view the report directly after completing their recall if they choose to do so. The Respondent Nutrition Report option is also available for viewing within the ASA24 demonstration site after the user completes the process of entering a 24-hour recall.
- Data on supplement intake are now collected at the same time as foods and beverages, rather than in a subsequent module. This allows participants to report supplement intake as part of what they consume on a given day, with corresponding time stamps that may be useful in examining patterns of intake across the day;
- An improved search has been developed, providing Respondents with the ability to filter results by food, beverage, and supplement categories. We have also revised food terms to be more intuitive to help Respondents more easily find foods, beverages, and supplements;
- New, more intuitive icons are available to facilitate editing of food terms and details;
- Help and tips are provided in context and downloadable resources are available for study staff and respondents;
- Additional portion size images have been added;
- Nutrient, food group and supplement databases have been updated to include:
- System requirements and accessibility
- View ASA24-2016 Respondent demonstration site (not available for ASA24-Canada-2016 and ASA24-Australia-2016)
- Evaluation and validation
- Register a study
- Help Guides for Respondents
Researchers using the 2016 version of the ASA24 system are encouraged to contact the ASA24 Support Team if there are tips that should be included in future troubleshooting or participant guides and to report bugs that are encountered using either the Respondent or Researcher websites.
ASA24-2016 was funded by the following NIH Institutes and Offices: National Cancer Institute (NCI) Division of Cancer Control and Population Sciences and Division of Cancer Prevention, National Heart, Lung, and Blood Institute (NHLBI), National Institute on Alcohol Abuse and Alcoholism (NIAAA), National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), and the NIH Office of Behavioral and Social Sciences Research (OBSSR) and Office of Dietary Supplements (ODS).
The development of ASA24-Canada-2016 has been supported by Health Canada's Food Directorate, the Alberta Cancer Foundation, and the Canadian Partnership Against Cancer through funds allocated to Alberta's Tomorrow Project, and contributions from a Canadian Institutes of Health Research New Investigator Award provided to Dr. David Hammond at the University of Waterloo.
The development of the Australian version of ASA24 was supported by an Australian Research Council Linkage, Infrastructure, Equipment and Facilities Grant (LE140100099). The project bought together five national institutions: Deakin University, University of Newcastle, University of Sydney, University of Wollongong, and the Commonwealth Scientific and Industrial Research Organisation.
