Atopic dermatitis associated with food allergy accelerates progression of allergic march

Studies demonstrate the comorbidity of food allergy (FA) and allergic march. This study assessed prevalence and comorbidity of allergic diseases in 3,000 Japanese students.

The lifetime prevalence of allergic rhinitis (AR), atopic dermatitis (AD), bronchial asthma (BA), and FA was 36%, 16%, 10%, and 7%, respectively.

Comorbidity with AD lowered the onset age of both BA and AR. Comorbidity with FA was the highest risk factor for the progression of allergic march.

AD associated with FA accelerates the subsequent progression of allergic march.
