OBJECTIVES: To assess the prevalence of @entity1576 in school-aged @entity1 and to determine the value of field spirometry. METHODS: Data on 313 1st and 4th graders from four public schools in Lisbon were analyzed. A respiratory self-answered questionnaire and standard spirometry were performed. Descriptive and bivariate analysis was followed by multiple logistic regression. RESULTS: Thirty-five percent of the @entity1 presented at least one episode of wheezing (18% >=  2 episodes), and 4% had @entity565 . Wheezing was more frequent with family history of @entity402 (adjusted OR = 2.7; 95%CI 1.4-5.1), maternal smoking during pregnancy, @entity1729 ( @entity1729 ) (adjusted OR = 2.8; 95%CI 1.2-6.2), @entity5924 (adjusted OR = 3.3; 95%CI 1.3-8.2), and @entity566 to aeroallergens (adjusted OR = 3.2; 95%CI 1.4-7.2). @entity565 was more frequent with previous history of @entity1729 (adjusted OR = 14.6; 95%CI 1.7-122.9) and @entity566 to aeroallergens (adjusted OR = 8.2; 95%CI 2.0-34.2). Fifty-five percent of spirometry measurements met the acceptability criteria of the American @entity1514 Society and of the European Respiratory Society. Wheezers presented mean lower z scores for forced expiratory volume in 1 second (FEV1), ratio between FEV1 and forced vital capacity (FVC) (FEV1/FVC), and forced expiratory flow between 25 and 75% (FEF25-75) (p < 0.05), as well as higher percentage of abnormal FEV1, FEV1/FVC and FEF25-75/ (FEF25-75, p < 0.05). CONCLUSIONS: This pilot study showed a high prevalence of obstructive airway symptoms in school-aged @entity1 in Lisbon. Symptoms assessed by the questionnaire showed good correlation with spirometric values. The small prevalence of @entity565 leads us to speculate that @entity565 is under-diagnosed in this population.
