The natural history of peanut and egg allergy in children up to age 6 years in the HealthNuts population-based longitudinal study.

Background: Prospectively collected data on the natural history of food allergy are lacking.

Objective: We examined the natural history of egg and peanut allergy in children from age 1 to 6 years and assessed whether a skin prick test (SPT) result or other clinical factors at diagnosis are associated with the persistence or resolution of food allergy in early childhood.

Methods: The HealthNuts cohort consists of 5276 children who were recruited at age 1 year and have been followed prospectively.
