Food-induced anaphylaxis among a population of adolescents – Report from the BAMSE survey

Methods Parent-reported questionnaire data from 2-3 months, and 1, 2 and 16 years from a large birth cohort were used (N=3153). Immunoglobulin E to 14 common allergens were analysed at 4 (n=2283) and 16 years (n=2510). In a subset of 371 adolescents, 15 additional food allergen extracts or components were analysed at 16 years. Data on dispensed adrenaline autoinjectors and inhaled steroids were extracted from a national register. Severity of food reactions and asthma were defined. The incidence of anaphylaxis was analysed in association with early-life risk factors.
