Popis: | Background Information about severe reactions to foods in adolescence is limited. Objective: To describe reactions to foods, including anaphylaxis, with regard to incidence, characteristics and associated risks, among 16-year-olds (adolescents) in a large, population-based birth cohort. Methods Parent-reported questionnaire data from ages 2-3 months, and 1, 2 and 16 years were used (N=3153). Anaphylaxis at age 16 years was defined per NIAID-FAAN criteria. Immunoglobulin E (IgE) antibodies to 14 common food and inhalant allergens were analyzed at ages 4 (n=2283) and 16 years (n=2510). Among adolescents with food-related symptoms and for whom blood was available (n=221), 25 additional food allergen extracts or allergen components were analyzed. Associations between reactions to foods, and sensitization and allergic multimorbidity were investigated. Results In the 12 months prior to the 16-year assessment, 8.5% of adolescents had food-related symptoms. This included 0.8% (n=24) adolescents who were classified as having anaphylaxis, yielding an incidence rate of 761/100,000 person-years. One-third of adolescents accessed healthcare during anaphylaxis. Allergic multimorbidity in infancy, as well as sensitization to foods and airborne allergens at age 4 years were associated with an increased risk for food-related symptoms in adolescence. Peanuts and tree nuts were the most common culprit foods for anaphylaxis, and fruits and vegetables for non-anaphylactic reactions. Adolescents with anaphylaxis were significantly more likely to be sensitized to storage proteins (Ara h 2, Cor a 9, Cor a 14) and to be polysensitized to foods (p |
