Abstract

Summary: Background: Over a fifth of children and adolescents suffer with asthma or atopic disease. It is unclear whether asthma impacts academic performance in children and adolescents, and little is known about the association of eczema, food allergy or hayfever and academic performance. Objective: To examine whether asthma, eczema, food allergy or hayfever impacts on adolescent academic performance and to assess the role of unmeasured confounding. Methods: This study used the Childhood and Adolescent Twin Study of Sweden cohort born 1992‐1998. At age 9‐12 years, parents reported on their child's ever or current asthma, eczema, food allergy and hayfever status (n = 10 963). At age 15, linked national patient and medication register information was used to create current and ever asthma definitions including severe and uncontrolled asthma for the same children. Academic outcomes in Grade 9 (age 15‐16 years) included: eligibility for high school (Grades 10‐12), and total mark of the best 16 subject units, retrieved from the Grade 9 academic register. Whole cohort analyses adjusted for known covariates were performed, and co‐twin control analyses to assess unmeasured confounders. Results: There were no associations found for asthma or food allergy at 9‐12 years and academic outcomes in adolescence. In addition, at age 15, there were no statistically significant associations with current, ever, severe or uncontrolled asthma and academic outcomes. Eczema and hayfever at age 9‐12 years were found to be positively associated with academic outcomes; however, co‐twin control analyses did not support these findings, suggesting the main analyses may be subject to unmeasured confounding. Conclusion and clinical relevance: Having asthma or an atopic disease during childhood or adolescence does not negatively impact on academic performance. This information can be used by clinicians when talking with children and parents about the implications of living with asthma or atopic disease.
