New IDATA data is now available. The Saliva Collection Form has been added to the biomarkers section and provides the timing of saliva sample collection. A new ActiHeart dataset has been added to the physical activity objective monitor section and provides heart rate and interbeat intervals on a small subset of the population.

Minor updates were made to the fitness test and accounting data.

The National Cancer Institute is happy to announce the availability of biospecimens for diet and physical activity data!

Preliminary applications will only be accepted until February 13, 2019. If you plan to submit an IDATA Biospecimen application this cycle, an approved preliminary application is required. Once your preliminary application has been approved, you will be notified and you will be able to continue and submit a full application. The deadline for full application submission is March 29, 2019.

Information is available regarding the IDATA study and IDATA biospecimens.

Please visit the IDATA Application for Biospecimens page to preview instructions about the process, review the IDATA Biospecimen Policies and Procedures, and begin an IDATA Preliminary Application for Biospecimens.

The following updates were made to the IDATA datasets available on CDAS:

There were minor fixes for the ASA24, Urine Collection, Participant and ACT24 datasets. There is new instrument data for the Harvard PAQ, Stanford PAQ, Four Day Food Record, and their associated accounting files.

The Interactive Diet and Activity Tracking in AARP (IDATA) Study is a methodologic study of device-based, internet-based, and conventional self-report instruments for assessing physical activity and diet in epidemiologic research. Scientists still have much to learn about the relationship between physical activity, diet, and disease. Limiting factors of current research are a lack of understanding about the measurement error properties of common assessment instruments and how to combine instruments to better measure food intake and physical activity participation. Instruments utilized by the IDATA Study include intensive 24-hour recalls of diet and time use, diaries, questionnaires, screeners, accelerometers, inclinometers, and urine biomarkers.

Information is available regarding the IDATA study and data collected.

Datasets are available to all qualified investigators for studies of physical activity and nutrition, and interested investigators can request access to IDATA Study data.
