3 Developing a taxonomy of outcomes related to diet, eating behavior and nutrition
Why do we need a taxonomy of dietary behavior?
Developing a taxonomy of outcomes can be useful to:
o
Demonstrate the extent of variation that exists
o
Systematically assess and categorize different outcomes
oApply standardized definitions
o
Synthesize existing literature
o
Resolve misunderstandings between disciplines
o
Facilitate mutual understanding and knowledge exchange
oExpedite data pooling
o
Provide a structure for future research

Method
• A four-step interactive Delphi method was employed.
• Input was provided by the ~80 scholars involved in WP 2.1
• Multidisciplinary
• International
Phase 4: final coordination
discussion among core workgroup and finalization Phase 3: live discussion
discussion and adaptation of taxonomy Phase 2: structuring of dietary terminology
outcomes were reduced and categorized into a compact taxonomy Phase 1: collection of dietary terminology
online mindmapping procedure
Developing a taxonomy of outcomes related to diet, eating behavior and nutrition 5
Method & results - Phase 1
o A total of 145 dietary behavior outcomes were specified
o
At various levels of detail
o
With myriad relations being indicated between the different
outcomes
Universität Konstanz
Method & results – Phase 1
Developing a taxonomy of outcomes related to diet, eating behavior and nutrition 7
Method & results – Phase 1
Universität Konstanz
Method & results – Phase 2
o Using structure that emerged in the mindmap o Taxonomy brought back to 43 entries
o
Within four main categories
o
And up to four additional levels of hierarchy
Developing a taxonomy of outcomes related to diet, eating behavior and nutrition 9
Method & results – Phase 3
o Taxonomy from Step 2 was discussed in a live, interactive meeting
o
Changes were processed in real time
o
Partners could evaluate and discuss changes to the taxonomy
right away

Method & results – Phase 4
Developing a taxonomy of outcomes related to diet, eating behavior and nutrition 11
o Taxonomy from Step 3 was finalized by core group
o
Adequate representation of all initial entries by workgroup members was ensured
o
Only entries relevant to entire lifespan were retained
o
Taxonomy was further reduced to 35 entries in 3 main
categories
Results: The final taxonomy
The three main categories represent three broad dimensions of dietary behavior:
1. Food Choice.
Everything that precedes the actual consumption phase2. Eating Behavior.
Everything to do with the actual act of eating3. Dietary Intake / Nutrition.
Everything to do with what is actually put in the mouthUniversität Konstanz
Discussion
o The fuzzy term “dietary behavior” covers a wide and diverse range of outcomes.
o
Nevertheless, these outcomes can be meaningfully reduced and structured into three main categories
o
The taxonomy can be used as a starting point to facilitate knowledge exchange, data sharing and evidence synthesis
Developing a taxonomy of outcomes related to diet, eating behavior and nutrition 13
Discussion
o The current taxonomy is a starting point and can be expanded in multiple directions
o Within DEDIPAC, the focus was on dietary behavior as an outcome
o Of course, diet can also be the determinant / exposure
factor
