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

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
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
