time schedule

state of the art report• Evaluation of literature of

(1) traditional dietary assessment methods(2) new dietary assessment methods

• specific analysis on feasibility (participationrates,time burden required, cost assessment, etc.)

• selection of new methodologies for pilot study(statistical methods and instruments)

progress

• 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

ideas in dietary assessment

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

web-based FFQ

• study design of pilot testing in preparation:

• combining assessment instruments

• new statistical methods to estimate individuals usual

dietary intake over past year

pilot study

experiences for historically new period of research
