The user interface for all 2016 versions of ASA24, including ASA24-Canada-2016 and ASA24-Australia-2016, employs a responsive design, meaning that these versions of the ASA24 system can be used on smartphones, tablets, 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.
Researchers can no longer register new studies using the U.S. or Canadian versions of ASA24-2016. Researchers will no longer be able to access the ASA24 respondent website for ASA24-2016 (U.S. and Canadian versions) after April 15, 2020. Additionally, the researcher websites for these versions will no longer be available after May 29, 2020 so researchers should download their data before the end of May.
The following features were new to ASA24-2016 when it was released:
- The user interface is written in HTML5. This enables ASA24 to work on all common web browsers. Previous versions required users to download the plug-in Microsoft Silverlight.
- Respondents can complete single- or multi-day food records (also known as food diaries) and 24-hour recalls, which expanded the types of studies and applications using ASA24.
- Researchers using the ASA24-U.S. and Canadian version have the option to provide respondents with a Respondent Nutrition Report, which shows how their intake on the day they completed a 24-hour recall or food record compared to country-specific dietary guidance and nutrient requirements. For food records, researchers must provide the report to the respondent after obtaining it from the researcher website. For 24-hour recalls, the respondent can view the report directly after completing their recall.
- Data on supplement intake are collected at the same time as foods and beverages, rather than in a separate 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.
- Respondents can filter search results by food, beverage, and supplement categories. We also revised food terms to be more intuitive to help respondents more easily find foods, beverages, and supplements.
- More intuitive icons are used to facilitate editing of food terms and details.
- Tips and guidance are available within the respondent website via a Help Center and icons on the screen; and Quick Start and Help Guides are available for study staff and respondents.
- Additional portion size images were added;
- Nutrient, food group, and supplement databases were updated to include:
The following NIH institutes and offices funded ASA24-2016: National Cancer Institute’s Division of Cancer Control and Population Sciences and Division of Cancer Prevention; National Heart, Lung, and Blood Institute; National Institute on Alcohol Abuse and Alcoholism; National Institute of Diabetes and Digestive and Kidney Diseases; Office of Behavioral and Social Sciences Research; and Office of Dietary Supplements.
The adaptation and maintenance of ASA24-Canada has been supported by financial and in-kind contributions from Health Canada's Food Directorate, the Alberta Cancer Foundation, the Canadian Partnership Against Cancer, and University of Waterloo researchers supported by funding from the Canadian Institutes of Health Research and the Canadian Cancer Society.
An Australian Research Council Linkage, Infrastructure, Equipment and Facilities Grant (LE140100099) supported the Australian version of ASA24. The project brought together five national institutions: Deakin University, University of Newcastle, University of Sydney, University of Wollongong, and the Commonwealth Scientific and Industrial Research Organisation.
