Prevalência de asma em adolescentes urbanos de Santa Maria (RS): Projeto ISAAC - International Study of Asthma and Allergies in Childhood

OBJECTIVE:To estimate the prevalence of respiratory symptoms and to analyze associated factors as well as peak expiratory fl ow measurements in schoolchildren.METHODS: This is a descriptive cross-sectional study with schoolchildren aged 10-14 from the city of Monte Aprazível (Southeastern Brazil). Questionnaires containing the asthma and rhinitis components of the International Study of Asthma and Allergies in Childhood were administered. The questionnaires also approached sociodemographic characteristics, predisposing factors, and family and personal medical history. Repeated measures of peak expiratory fl ow in the children, and of black carbon and particulate matter (PM 2,5 ) concentration levels were carried out. RESULTS:The prevalence of asthma and rhinitis symptoms was 11% and 33.2%, respectively. Among asthmatic children, 10.6% presented four or more wheezing attacks in the past 12 months. Past family history of bronchitis and rhinitis was associated with presence of asthma (p=0.002 and p <0.001) and rhinitis (p <0.001 and p<0.001, respectively). Regarding rhinitis, there was association with presence of mold or cracks on the house (p=0.009). Rhinitis was most frequent from June to October, a period that matches the sugarcane harvest season. Daily prevalence of peak expiratory fl ow below 20% of the median of each child's measurements was higher in days with greater PM 2,5 concentration. CONCLUSIONS:The prevalence of asthma symptoms is below and that of rhinitis is above the national average. Although within acceptable levels, pollution in the cane trash burn season may contribute to the exacerbation of asthma and rhinitis episodes.

“…Non-atopic asthma is more common in developing countries and it is associated with poverty, indoor and outdoor pollution, diet, and stress ( Cooper et al, 2008 , Cooper et al, 2012 ). The increase in non-atopic asthma in Latin America needs to be understood and seems to be associated with a Western lifestyle and urbanization ( Barreto et al, 2006 , Cassol et al, 2005 , Cooper et al, 2008 ), including psychosocial and environmental risk factors ( Maia et al, 2004 , Strina et al, 2014 ), since genetic factors alone cannot explain the observed increase over such a short duration ( Boechat et al, 2005 , Cassol et al, 2005 ). Intrafamilial violence against children might be one of these stressors associated with asthma and the severity of this condition ( Wright, 2011 , Wright and Steinbach, 2001 ).…”

This study aims to describe the types of intrafamilial violence perpetrated against children according to living conditions, family factors, and child characteristics, and to identify the association between types of intrafamilial violence and asthma symptoms in atopic and non-atopic children. A cross-sectional study was carried out with 1,370 caregivers as part of the Social Changes, Asthma and Allergy in Latin America (SCAALA) study, conducted in 2006 in Brazil. The study population was selected by random sampling. The main outcome measures were atopic and non-atopic asthma. We investigate the association between intrafamilial violence and asthma symptoms in atopic and non-atopic children. A backward multivariate logistic polytomous regression was performed to verify the main association. Nonviolent discipline (NVD) and maltreatment nonviolent discipline (MNVD) were positively associated with non-atopic asthma symptoms (NVD: odds ratio (OR) = 1.95/95% confidence interval (CI) = 1.17–3.25; MNVD: OR = 1.95/95% CI = 1.19–3.20). However, for the most severe intrafamilial violence, this association was not found after control of potential confounders. This study demonstrates the effect of types of intrafamilial violence on non-atopic asthma. Intrafamilial violence against children represents one more component in the determination of non-atopic asthma in Latin America.

Objective: To examine the association between wheezing in children and adolescents and living downwind of the dispersion plume of atmospheric pollutants emitted by the Guamaré Petrochemical Complex, in the state of Rio Grande do Norte, Brazil. Methods:Cross-sectional study of wheezing in children and adolescents (aged 0 to 14 years) living in the vicinity of the Guamaré petrochemical complex in 2006. The standardized International Study of Asthma and Allergies in Childhood questionnaire was used, with additional questions concerning tobacco use, income, living conditions, and educational achievement. Daily concentrations of PM 10 , PM 2.5 , black carbon, SO 2 , NO 2 , O 3 , benzene, toluene, and xylenes were measured at a fixed monitoring station. According to their position relative to wind direction, communities present in the area affected by plant emissions were categorized into one of two groups, exposed communities and reference communities.Results: Two hundred and nine children and adolescents took part in the study. Mean daily concentrations of the monitored pollutants were consistently below established acceptable upper limits. The prevalence of wheezing in the 12 months prior to study was 27.3%. After adjustment, statistically significant associations were found between wheezing and living in exposed communities (adjusted odds ratio [OR adj ] 2.01; 95% confidence interval [95%CI] 1.01-4.01), male gender (OR adj 2.50; 95%CI 1.21-5.18), and age 0 to 6 years (OR adj 5.00; 95%CI 2.41-10.39). Conclusion:Even with low levels of atmospheric pollutants, respiratory symptoms in children and adolescents were associated with living downwind of a petrochemical plant. Male preschoolers were the most vulnerable group. Resultados: Participaram do estudo 209 crianças e adolescentes. As concentrações médias diárias dos poluentes monitorados mantiveramse abaixo dos limites estabelecidos nos padrões de qualidade do ar. A prevalência de sibilos nos últimos 12 meses foi de 27,3%. Associações estatisticamente significantes com sibilos nos últimos 12 meses foram verificadas mesmo após ajustamentos para comunidades expostas [razão de chances (odds ratio, OR ajust ) = 2,01; intervalo de confiança de 95% (IC95%) 1,01-4,01], gênero masculino (OR ajust = 2,50; IC95% 1,21-5,18) e idade de 0 a 6 anos (OR ajust = 5,00; IC95% 2,41-10,39). J Pediatr (Rio J) Conclusão:Mesmo em baixas concentrações de poluentes atmosfé-ricos, a ocorrência de sintomas respiratórios em crianças e adolescentes nas comunidades no entorno de um PPQ esteve associada a residência na direção preferencial dos ventos, mostrando-se mais vulnerável o grupo de pré-escolares do gênero masculino.J Pediatr (Rio J). 2010;86(4):337-344
