Outcome measures
Primary outcome

1 of the clinical part of the EDEN questionnaire (monthprevalence).
The number of participants in the study with a confirmative answer on question
2 of the clinical part of the EDEN questionnaire (one-yearprevalence).
Background summary
Data originating from allergology services concerning what is known as *patch
test population* suggest that the frequency of allergies to fragrances is
continuously increasing. Given the widespread use of substances with fragrance
content (detergents, shampoos, deodorants etc) by the general population, it is
understandable how this increase may be relevant with regard to public health.
Epidemiology can provide a crucial contribution in evaluating the importance of
allergy to fragrances, estimating the frequency of the disease within the
population and assessing the role of potential risk factors.
Study objective
To estimate the one year-prevalence of contact allergy to fragrance ingredients
in the general population of six different geographical areas in Europe spread
over five different countries
Study design
The study design of EDEN-FS is quantatative cross-sectional
Study burden and risks
The patchtestprocedure has been administered on a large scale for many
decennia. Adverse reactions or health risks are not known to the patchtest
procedure. The only burden to the participant is that he/she has to avoid
contact with water in the places on the skin where the patches are attached
(the back).
