EuroPrevall researchers publish survey methodology

Protocols used for obtaining epidemiological survey data in eight centres throughout Europe have been published by researchers working on EuroPrevall, the EU-funded multidisciplinary project which aims to improve the quality of life for food allergy sufferers. The survey was designed to gain an estimate of the prevalence of food allergy and exposure to known or suspected risk factors for food allergy across Europe.

The protocol provides specific instructions on the sampling strategy, the use of questionnaires, and collection of blood samples for immunological analyses in the children (aged 7-10 years) and adults (aged 20-54 years) who participated in the studies. Questionnaires were provided to schools in the area to estimate their preparedness for dealing with food allergy amongst pupils. Study subjects who reported adverse reactions to foods were asked to participate in a full clinical evaluation that included a double blind placebo controlled food challenge.

The authors of this paper conclude the outcome of their epidemiological studies will help to improve understanding of several important aspects of food allergies in the European Community, providing for more well-informed policies and effective measures of disease prevention, diagnosis and management.
