EARLY respiratory infection burden was associated with greater childhood atopic dermatitis risk across two independent birth cohorts. Infection Burden and Childhood Atopic DermatitisResearchers investigated whether infections occurring during the first 3 years of life were associated with childhood atopic dermatitis through age 10 years. Respiratory Infections Drive the AssociationFurther analysis indicated that respiratory infections were primarily responsible for the observed relationship. Long Term Relationship Requires Further StudyThe consistent dose dependent association across two independent populations supports a possible long term relationship between early respiratory infections and childhood atopic dermatitis. Early respiratory infection burden and atopic dermatitis in childhood.
