Description
The aim of this study is to develop a web-based food frequency
questionnaire (eFFQ-CH), using the menuCH photo book and the
framework of a food frequency questionnaire developed at ZHAW
Wädenswil (the ZHAW FFQ). The development work will follow a unique
approach based on the results of the menuCH Survey, the first
national, representative nutritional data of the Swiss population.
The project will deliver a web-based dietary assessment tool for an
adult population in Switzerland with advantages over other existing
tools.
Following a multi-stage approach, we first aim to use menuCH
results to guide the development of the new composite FFQ (BLV
photo book and parts of the ZHAW FFQ). In this process, we will
also consider suggestions from experts in other language-regions in
Switzerland. Using these inputs, the FFQ will be optimized for
structure, food items, photographs and other aspects of respondent
usability (e.g. compliance). The tool will be implemented into a
state-of-art content management platform, offering many advantages
for research applications (including FAIR data principles). A
validation study will be conducted, by testing the tool against the
validated ZHAW FFQ and also studying reproducibility. Results will
be summarized, and used to make final adjustments.
