A comparison of childhood asthma case definitions based on parent-reported data.

ABSTRACT:

Purpose

The purpose of this study was to compare research definitions of childhood asthma based on parent-reported data.

Methods

We conducted a multicenter, prospective cohort study of 921 infants hospitalized for bronchiolitis. Follow-up was conducted via biannual parent interviews. Asthma definitions were developed using parent-reported data: clinician diagnosis by the age of 5 years ("broad definition"), clinician diagnosis by the age of 5 years with either asthma medication use or asthma symptoms during the age of 4-4.9 years ("epidemiologic definition"), clinician diagnosis by the age of 5 years with either long-term inhaled corticosteroid use or asthma symptoms during the age of 4-4.9 years ("strict definition"), and a "flexible definition" met by any two of the three
