Methods and Tools

A variety of tools are under development to sharpen our understanding of energy balance mechanisms, including the following:

Physical Activities Completed over Time in 24 Hours (ACT-24)

  • This is a web-based physical activity evaluation tool developed by the NCI where participants can enter the activities they engaged in during the previous day.
  • This assessment tool will be employed in future NIH-AARP Diet and Health Studies as well as in other cohorts to improve our understanding of physical activity and disease.
  • For more information, see this additional webpage.

Automated Self-Administered 24 hour Dietary Recall (ASA24)

  • This web-based tool is based on a modified version of the interviewer-administered Automated Multiple Pass Method (AMPM) 24-hour recall developed by the U.S. Department of Agriculture (USDA).
  • The program includes user-friendly features such as icons, pictures, and audio cues.
  • ASA24 is available free of charge to researchers, clinicians and teachers.
