Dataset Information

Quality of life is lower in adults labeled with childhood-onset food allergy than in those with adult-onset food allergy.

ABSTRACT:

Background

Immunoglobulin E-mediated food allergy (FA) affects children and adults with variable age of onset. Phenotype and quality of life (QoL) differences between childhood-onset FA (COFA) and adult-onset FA (AOFA) are not known.

Objective

To identify phenotypic and QoL differences between AOFA and COFA.

Methods

A cross-sectional study of adults (≥18 years old) seen at Northwestern Memorial HealthCare clinics between 2002 and 2017 with an International Classification of Diseases ninth and tenth revision diagnosis of FA. Subjects completed a FA history survey and a FA QoL questionnaire. FA characteristics and QoL scores were compared between groups.
