To assess the prevalence and severity of asthma and allergic diseases in schoolchildren residing in Ciudad Juarez, Chihuahua. Material and Methods. A crosssectional study was conducted from April 1998 to May 1999, among 6 174 children from 53 schools in Ciudad Juarez, Chihuahua. The method used was the one recommended by the International Study of Asthma and Allergies in Childhood (ISAAC) to determine the prevalence and severity of asthma, rhinitis, and eczema. Parents were asked to answer a standardized questionnaire on current and cumulative prevalence of asthma, rhinitis, and eczema. A sample stratified by level of pollution was selected. Results. The cumulative prevalence of medically diagnosed asthma and wheezing was 6.8% (95% CI 6.2, 7.4) and 20% (95% CI 19.7, 21.8), respectively. The prevalence of wheezing in the last 12 months was higher in the group aged 6-8 years than in those aged 11-14 years (9.7% vs. 5.8 %, p<0.01). The prevalence of medically diagnosed rhinitis was 5.0 % (95% CI 4.5, 5.6). The prevalence of medically diagnosed eczema was 4.9% (4.3, 5.4). The prevalence of eczema symptoms in the last 12 months was 12.7% in the 6-8 years group and 13.3% in the 11-14 year group, respectively. Severe symptoms of asthma were significantly higher in the 6-8 years group and during

Parameters of lung inflammation in asthmatic as compared to healthy children in a contaminated city

“…These results are consistent with the well known facts that asthmatic children have more respiratory symptoms, lower lung function, and evidence of airway inflammation compared to non-asthmatic children [4-6] which also increase in places with high air pollution.…”

Association between Allergic Rhinitis and Asthma Control in Peruvian School Children: A Cross-Sectional Study

“…This is particularly relevant, considering that AR is underdiagnosed at primary level health facilities in Peru [18, 19] and other Latin American countries [38, 42–45]. Our proposed explanatory model is powerful enough for reliably explaining factors related to an inadequate control of asthma.…”

Virus más frecuentemente aislados en la exacerbación de asma y su correlación con niveles de eosinófilos e inmunoglobulina E sérica total

“…En México, la prevalencia de asma oscila entre 2,7% y 21,8%. 10 En nuestro estudio, se encontró una prevalencia acumulada de exacerbación de asma de 2,15%. Alrededor del 1-2% de los niños con asma necesitan ser hospitalizados por la dificultad respiratoria.…”
