Eczema in early childhood, sociodemographic factors and lifestyle habits are associated with food allergy: a nested case-control study.

Background: Studies suggest an increase in food allergy prevalence over the last decade, but the contributing factors remain unknown. The aim of this study was to evaluate the association between the most common food allergies and atopic history, sociodemographic characteristics and lifestyle habits.

Methods: We conducted a case-control study nested within the SPAACE study (Surveying Prevalence of Food Allergy in All Canadian Environments) – a cross-Canada, random telephone survey.

Rate, triggers, severity and management of anaphylaxis in adults treated in a Canadian emergency department.

Background: The Cross-Canada Anaphylaxis Registry (C-CARE) assesses the triggers and management of anaphylaxis and identifies predictors of the development of severe allergic reactions and of epinephrine use. Here, we present data from an urban adult tertiary care emergency department (ED) in Montreal, Canada.

Methods: Potential anaphylaxis cases were identified using ICD-10 codes related to anaphylaxis or allergic reactions.
