“…In addition, these factors appear to determine the level of reactivity or the predisposition to acquire the disease and the presence of atopy (11)(12)(13)(14). Currently, no specific etiology has been established that accounts for clinical characteristics and particular pathologies, immunological mechanisms, nor the environmental factors that influence the development of asthma and allergic diseases (15)(16)(17)(18)(19).…”

Asthma and allergic rhinitis were analyzed in a random sample of school children (n=6174) residing in Ciudad Juarez, Chihuahua, Mexico. The International Study of Asthma and Allergies in Childhood methodology was applied through a standardized questionnaire. The sample was obtained with a bietapic design. Cumulative prevalence of asthma and wheezing was 6.8% (95% CI 6.2, 7.4) and 20% (95% of CI 19.7, 21.8) respectively; the prevalence of rhinitis was 5.0% (95% CI 4.5, 5.6). Family history of asthma odds ratio (OR) 2.33 (95% CI 1.78-3.05), respiratory infection after birth (OR) 3.44 (95% CI 2.76-4.29), and exposure to environmental tobacco (OR) 1.35 (95% CI 1.06-1.68) were the strongest risk factors for asthma and allergic rhinitis. The multifactorial etiology of asthma and allergic rhinitis was confirmed, as well as the importance of early exposure to environmental factors.

Impact of air pollution on pulmonary function and respiratory symptoms in children. Longitudinal repeated-measures study

et al. 2010

BackgroundSalamanca, Mexico occupied fourth place nationally in contaminating emissions. The aim of the study was to determine the impact of air pollution on the frequency of pulmonary function alterations and respiratory symptoms in school-age children in a longitudinal repeated-measures study.MethodsWe recruited a cohort of 464 children from 6 to 14 years of age, from two schools differing in distance from the major stationary air pollution sources. Spirometry, respiratory symptoms and air pollutants (O3, SO2, NO, NO2, NOx, PM10,) were obtained for each season. Mixed models for continuous variables and multilevel logistic regression for respiratory symptoms were fitted taking into account seasonal variations in health effects according to air pollution levels.ResultsAbnormalities in lung function and frequency of respiratory symptoms were higher in the school closer to major stationary air pollution sources than in the distant school. However, in winter differences on health disappeared. The principal alteration in lung function was the obstructive type, which frequency was greater in those students with greater exposure (10.4% vs. 5.3%; OR = 1.95, 95% CI 1.0-3.7), followed by the mixed pattern also more frequent in the same students (4.1% vs. 0.9%; OR = 4.69, 95% CI, 1.0-21.1). PM10 levels were the most consistent factor with a negative relationship with FVC, FEV1 and PEF but with a positive relationship with FEV1/FVC coefficient according to its change per 3-month period.ConclusionsStudents from the school closer to major stationary air pollution sources had in general more respiratory symptoms than those from the distant school. However, in winter air pollution was generalized in this city and differences in health disappeared. PM10 levels were the most consistent factor related to pulmonary function according, to its change per 3-month period.

Prevalence of asthma and other allergic diseases in school children in Ciudad Juarez, Chihuahua. Salud Publica Mex 2001;43:433-443. The English version of this paper is available at: http://www.insp.mx/salud/index.html AbstractObjective. 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
