Background: Food allergy is negatively associated with health-related quality of life (HRQL). Although diferences exist between parents and children, less is known about age-specifc diferences amongst children. As such, we aimed to identify if age, as well as other factors, are associated with food allergy-specifc HRQL in an objectively defned population of children. Methods: Overall, 63 children (boys: n=36; 57.1%) with specialist-diagnosed food allergy to 1+foods were included. Parents/guardians completed the Swedish version of a disease-specifc questionnaire designed to assess overall- and domain-specifc HRQL. Descriptive statistics and linear regression were used. Results: The most common food allergy was hen’s egg (n=40/63; 63.5%). Most children had more than one food allergy (n=48; 76.2%). Nearly all had experienced mild symptoms (e.g. skin; n=56/63; 94.9%), and more than half had severe symptoms (e.g. respiratory; 39/63; 66.1%). Compared to young children (0–5 years), older children (6–12 years) had worse HRQL (e.g. overall HRQL: B=0.60; 95% CI 0.05–1.16; p<0.04.). Similarly, multiple food allergies, and severe symptoms were signifcantly associated with worse HRQL (all p<0.05) even in models adjusted for concomitant allergic disease. No associations were found for gender or socioeconomic status. Conclusion: Older children and those with severe food allergy have worse HRQL.
