ASA24 is a freely available web-based tool for epidemiologic, interventional, behavioral, or clinical research from NCI that enables multiple automatically coded self-administered 24-hour recalls and food records. There are U.S., Canadian, and Australian versions.
ASA24 consists of a Respondent Web site used to collect recall and food record data in English or Spanish for the U.S. version, and in English and French for the Canadian version. There is also a Researcher Web site used to manage study logistics and obtain data analyses. The ASA24 system can also be used by clinicians for diet assessment and nutritional counseling, and by educators for teaching about nutrition or dietary assessment.
