Parental-reported allergic disorders and emergency department presentations for allergy in the first five years of life; a longitudinal birth cohort.

More than 10% of children up to 5 years have a parental-reported allergic disorder, and 3.6% presented to ED. Parental-report of eczema and/or asthma and late introduction of solids were predictors of parental-report of allergy. Spring birth and maternal asthma were predictors for ED presentation for allergy.
