Official title
Interactive Diet and Activity Tracking in AARP (IDATA): Biomarker Based Validation Study of Internet-Based and Conventional Self-Report Instruments for Assessing Diet and Physical Activity Within AARP
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This research trial studies how well internet-based and self-report instruments measure food intake and physical activity levels and their relationship with disease within American Association of Retired Persons (AARP) members. Comparing new internet-based questionnaires developed by the National Cancer Institute that report all the foods consumed and activities performed in an entire day to standardized physical measurements may help to determine if the information collected is accurate.
