Questionnaires
In the baseline and the follow-up survey, both parents and
their child respectively completed a self-administered questionnaire,
which was a modified version based on the Children’s Questionnaire recommended by the American Thoracic Society (ATS-DLD-78-C)
The following information was
obtained from the questionnaires: the child’s current and past
history of respiratory symptoms and diseases, parental history
of allergic diseases, indoor environmental factors, their
socioeconomic status, as well as the frequency and extent of
the physical activity of the children
The questionnaires used
in the second survey were the same as those used in the
baseline survey, except the questions about basic information
already obtained in the baseline survey were not repeated in
the questionnaire for the parents.
