ASA24-2022

As with all versions since the release of ASA24-2016, the ASA24-2022 respondent website used a responsive design, allowing it to be used on smartphones, tablets, laptops, and desktops. This allowed study participants to enter dietary intake data at any time and from any location with Internet service.

Other features of ASA24-2022 included:

• The user interface is written in HTML5. This enables ASA24 to work on all common web browsers.
• Respondents can complete single- or multi-day food records (also known as food diaries) and 24-hour recalls.
• Supplement intake is 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.
• Researchers 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 compares to country-specific dietary guidance and nutrient requirements. A new page was added to the RNR for the US version of ASA24-2022 in November 2023. This page compares nutrient intake from foods and drinks vs. supplements.
• Respondents can build recipes and use these recipes in subsequent intakes.
• A sleep module is available in the ASA24-2022 as it was with ASA24-2020. Researchers have the option to ask respondents about sleep timing, duration, and quality. This will allow them to examine the associations between sleep and dietary intake, timing of eating, and other variables in the context of the 24-hour day.
• Tips and guidance are available within the respondent website via a Help Center and icons on the screen; and instructional videos and Quick Start Guides are available for study staff and respondents.
