Prevalence of Asthma, Rhinitis and Eczema in 6 - 7 Years Old Students From the Western Districts of São Paulo City, Using the Standardized Questionnaire of the “International Study of Asthma and Allergies in Childhood” (Isaac)-Phase Iiib

Abstract

The aims of the present work were the evaluation of allergic disease prevalence among 6 and 7 year-old students from the western districts of São Paulo city and the comparison of these data with those obtained in the International Study of Asthma and Allergies in Childhood (ISAAC) phase I, performed in the central-southern districts of São Paulo, using the ISAAC standardized written questionnaire. METHODS: 5,040 questionnaires were distributed and 3,312 were returned. Proportional differences were estimated by Chi square or Fisher exact tests. Odds Ratio and 95% confidence intervals between genders and allergic diseases were calculated. Values of p<0.05 were considered statistically significant. RESULTS: The corrected prevalences found were: asthma 24.4%, medical diagnosis of asthma 5.7%, rhinitis 25.7%, rhinoconjunctivitis 11.3%, medical diagnosis of rhinitis 20.0%, atopic eczema 9.2%. Significant associations between asthma and rhinitis (OR=3.3), asthma and eczema (OR=2.2), and rhinitis and eczema (OR=2.8) occurred. The male gender was prevalent regarding asthma and rhinitis. Compared to data from ISAAC phase I, higher asthma prevalence and severity, and lower values for rhinitis and eczema were observed in this study. CONCLUSIONS: The present study evidenced high prevalences for asthma and rhinitis compared to the children's medical diagnosis. The male gender predominated in all positive responses regarding asthma and rhinitis. The most frequent associations observed were between asthma and rhinitis and asthma and eczema. In the western districts of São Paulo, a higher prevalence of asthma symptoms and severity and lower prevalences for rhinitis and eczema occurred compared to the central-southern districts of the city.

“…The participants with EIB differed from those without regarding the presentation of asthma and baseline FEV 1 . The Kolmogorov-Smirnov test showed that the numerical variables had a normal distribution, allowing the use of parametric tests ( Table 2) We found a significant, inverse association between the presentation of asthma and the baseline FEV 1 , in L and in percentage of the predicted value.…”

“…However, the predictive value of the dyspnea scale was suboptimal, especially when it was applied to the participants with lower percentage falls in FEV 1 .…”

“…(26) All of the children and adolescents in our sample had physician-diagnosed asthma and were using anti-inflammatory agents, both of in the present study is its tight range of possible scores, resulting in a lack of precision when compared with the Borg scale, which is a ten-point scale and therefore more accurate. In addition, the percentage fall in FEV 1 was positively associated with the presentation of the disease, which allowed the word labeled visual analog dyspnea scale to be tested in children and adolescents with different levels of impairment in FEV 1 .…”

“…(1)(2)(3) Patients with asthma show considerable variation in their perception of breathlessness (dyspnea). (4)(5)(6) When individuals with asthma experience dyspnea, the intensity of the symptoms does not correlate with the degree of airway obstruction observed by spirometry.…”

“…This difference is probable caused by geographical differences. 3 The cumulative prevalence of AR is about 20%. In Canada, it is estimated that 20-30% of the populations suffer from AR.…”
