CHONG NETO, Herberto José and ROSARIO, Nelson Augusto. Expanding the application of a standardized questionnaire on recurrent wheezing in infancy. J. Pediatr. (Rio J.) [online]. 2009, vol.85, n.2, pp. 170-174. ISSN 0021-7557. http://dx.doi.org/10.1590/S0021-75572009000200014.
OBJECTIVE: To verify the possibility of extending the application of an instrument to investigate the prevalence and clinical characteristics of wheezing in infants. METHODS: A cross-sectional study conducted as part of the International Study on Wheezing in Infants (EISL, Estudio Internacional de Sibilancias en Lactantes). A questionnaire was administered to parents of infants aged 12 to 15 months (group I) and 16 to 24 months (group II) infants. RESULTS: One thousand, three hundred and sixty-four infants (45.4%) in group I and 250 (46.7%) in group II had had at least one episode (p = 0.58). The numbers of patients on inhaled β2-agonists, inhaled or oral steroids and/or leukotriene modifiers were similar in both groups (p = 0.52, 0.12, 0.06, and 0.75). There were no differences between the groups in terms of night-time symptoms, shortness of breath, emergency room visits, asthma hospitalization or asthma diagnosed by a doctor (p = 0.09, 0.28, 0.54, and 0.45). CONCLUSION: The application of the questionnaire can be extended to include infants up to 24 months of age.
