Welcome to the Dietary Assessment Calibration/Validation (DACV) Register, a register of
calibration/validation studies and publications.
The register contains studies and publications which compare
dietary intake estimates from two or more dietary assessment methods. Dietary assessment methods include:
- Food records or diaries (including weighed intakes)
- Dietary recalls
- Food frequency questionnaires (FFQ's)
- Dietary histories
- Observed intakes
- Chemical analyses of duplicate collections of foods consumed
- Biological assessments (e.g. doubly-labelled water, plasma carotene, etc.)
The following is a list of studies that are not included in the register:
- Food composition studies
- Studies which assess only household and not individual food consumption
- Reliability studies (studies which administer the same method at multiple times)
The following is a list of publications that are not included in the register:
- Abstracts submitted to conferences
- Publications that only review or comment on other work
The history of this effort dates back to 1993 when the idea for
creating such a register was suggested at the First International Conference on
Dietary Assessment in Minneapolis, Minnesota.
Development and maintenance of this site is a collaborative effort between the
Division of Cancer Prevention and the
Division of Cancer Control and Population Sciences
of the National Cancer Institute. It has been developed
as a means of keeping the international nutrition and health community aware of
calibration/validation studies on dietary assessment methods being conducted worldwide.
