“…In approximately 10.0% of the patients there was an association of active asthma, rhinitis, and atopic eczema. These data differ from other authors who observed asthma prevalence 3.4 times higher among patients with rhinitis (3, 10).…”

The objective of this study was to evaluate the role of rhinitis (R) and atopic eczema (E) on asthma severity among asthmatic (A) schoolchildren identified by the International Study of Asthma and Allergies in Childhood written questionnaire (WQ). WQ was applied to parents of 6-7-yr-old schoolchildren (SC, n=3033), and to adolescents (AD, 13-14 yr old, n=3487), living in Sao Paulo, Brazil. An affirmative response to 'has your child/have you had wheezing/whistling in the last year' identified those with A, and an affirmative response to 'the last 12 months has your child/have you had sneezing/runny/blocked nose when he/she you did not have a cold/flu?' identified those with R. Subjects with an affirmative response to 'has your child/have you had this itchy rash at any time in the past 12 months?' were identified as having E. Subjects who had R associated with A were identified as AR and those with A associated with R and E as ARE. A who had at least two affirmative responses to questions for asthma severity: speech disturbance, more than four acute attacks, sleep disturbance, and wheezing with exercise were defined as having severe asthma. 22.1% AD and 24.3% SC were identified as A; 47.1% of those AD and 42.0% SC had AR and 10.0% of those AD and 12.8% of SC had ARE. Considering ARE, AR and A groups, speech disturbance during an acute episode of asthma was significantly higher among ARE AD (20.0% vs. 11.5% vs. 8.7%, p<0.05), and ARE SC (22.1% vs. 13.9% vs. 10.5%, p<0.05) in comparison with A. Likewise, more than four acute attacks in the last year was significantly higher among ARE AD (24.0% vs. 14.0% vs. 10.5%, p<0.05) and ARE SC (32.6% vs. 19.4% vs. 12.8%, p<0.05) as the frequency of sleep disturbance due to wheezing, for AD (61.3% vs. 42.0% vs. 38.4%, p<0.05) and SC (77.9% vs. 67.3% vs. 58.4%, p<0.001) and for 'wheezing associated with exercise' for AD (72.0% vs. 47.5% vs. 39.9%, p<0.001) and SC (36.8% vs. 31.4% vs. 14.1%, p<0.001). Prevalence of severe asthma was higher among ARE AD (57.3% vs. 31.9% vs. 27.0%, p<0.05) and ARE SC (52.6% vs. 36.9% vs. 22.5%). In patients with A, the presence of R or E are risk factors for severe asthma, and both together (R and E) are a higher risk.

“…Our measure of asthma prevalence in Hispanic/Spanish children was similar to that found in a sister study in neighboring Ciudad Juárez, Mexico[52,53]. Klinnert, et al, reported demographic and environmental differences between acculturated and non-acculturated (as measured by language preference) Hispanics, predominantly of Mexican ancestry, in a clinical cohort at risk for asthma in the Southwestern United States[11].…”

Variability in childhood allergy and asthma across ethnicity, language, and residency duration in El Paso, Texas: a cross-sectional study

BackgroundWe evaluated the impact of migration to the USA-Mexico border city of El Paso, Texas (USA), parental language preference, and Hispanic ethnicity on childhood asthma to differentiate between its social and environmental determinants.MethodsAllergy and asthma prevalence was surveyed among 9797 fourth and fifth grade children enrolled in the El Paso Independent School District. Parents completed a respiratory health questionnaire, in either English or Spanish, and a sub-sample of children received spirometry testing at their school. Here we report asthma and allergy outcomes across ethnicity and El Paso residency duration.ResultsAsthma and allergy prevalence increased with longer duration of El Paso residency independent of ethnicity and preferred language. Compared with immigrants who arrived in El Paso after entering first grade (18%), lifelong El Paso residents (68%) had more prevalent allergy (OR, 1.72; 95% CI, 1.32 - 2.24), prevalent asthma (OR, 1.75; 95% CI, 1.24 - 2.46), and current asthma (OR, 2.01; 95% CI, 1.37 - 2.95). Spirometric measurements (FEV1/FVC and FEF25-75) also declined with increasing duration of El Paso residency (0.16% and 0.35% annual reduction, respectively).ConclusionThese findings suggest that a community-wide environmental exposure in El Paso, delayed pulmonary development, or increased health of immigrants may be associated with allergy and asthma development in children raised there.
