SchoolNuts (SN)
SchoolNuts is a cross-sectional population-based study that aims to measure the prevalence of food allergy in the early adolescent age group, as well as to understand risk factors for recurrent and severe accidental food ingestion reactions and to determine clinical predictors of food challenge outcomes. 9,630 children aged 10-14 years have been recruited from randomly-selected schools across Melbourne.
Participants have completed surveys on allergic disease status, food allergy-specific quality of life, pubertal development and risk-taking behaviour. Parents of participating children have completed questionnaires on family history of allergic disease and environmental exposures. Participants suspected of having a food allergy have attended a hospital clinic for allergy testing and treatment.
