Department of Epidemiology (head: Heiner Boeing)
German Institute of Human Nutrition Potsdam-Rehbrücke

2. overview funding: Public Health Executive Agency
project duration: April 2007 to June 2009 (27 months)
consortium: 20 partners + 1 collaborating institution
international consultants:
Amy Subar, National Cancer Institute, Washington, USA
Alan Kristal, Fred Hutchinson Cancer Research Center, Seattle, USA
Paul Hephurn, Representative of ILSI Novel food task force, Europe
International need for a collaborative effort for innovative methods of measuring diet

3. work flow Literature Review SWOT-Analysis of new technologies
feasibility reports on
dietary assessment
state of the art evaluation
preliminary SOP´s for innovative methods
pilot studies
final SOP´s for innovative methods
assessing diet in epidemiological studies

4. time schedule
R = report L = leaflet WS = workshop

5. progress state of the art report Evaluation of literature of
(1) traditional dietary assessment methods
(2) new dietary assessment methods
specific analysis on feasibility (participation
rates,time burden required, cost assessment, etc.)
selection of new methodologies for pilot study
(statistical methods and instruments)

6. ideas in dietary assessment
web-based automated FFQ´s
self-administered, automated, web-based 24-hour dietary recalls
real time data collection of food records
voice recognition software
combining methods
FFQ with 24-hour recalls

8. advantages beyond paper and pencil
web-based FFQ
advantages beyond paper and pencil
cleaner data
may take less time to complete
disadvantages beyond paper and pencil
still FFQ
computer access and related technology issues
feasibility research in IDAMES:
Pilot studies in 6 centres

9. study design of pilot testing in preparation:
pilot study
study design of pilot testing in preparation:
combining assessment instruments
new statistical methods to estimate individuals usual dietary intake over past year
experiences for historically new period of research
