Interviews and Standardized Questionnaires
All children and their parents were interviewed according to a modified
version of the standardized questionnaire used in the Environmental and
Childhood Asthma study 27. The questionnaire included
demographic data; family history of allergy and asthma; personal history
of asthma, rhinitis, and other allergic manifestations, and medications
and health care usage. Subjects were also administered the
well-validated Asthma Control Test (ACT) 28 and Asthma
Quality of Life Questionnaire (AQLQ) 29.
