Accidental ingestions to known allergens by food allergic children and adolescents.

The number of severe reactions, and epinephrine need, differs in children compared with adolescents, although many of the reported reactions in both groups occurred before the age of 12. There were also regional differences with the United States reporting a lower number of AIs and less AIs per year than the other participating regions, as well as increased rates of AI in participants with more than one food allergy. Further characterization of the differences in AIs between children and adolescents, as well as between regions, is needed to assist with more patient-centered anticipatory guidance.
