“…Socioeconomically disadvantaged participants presented with a higher prevalence of asthma symptoms and major crises 4 . This was consistent with Britto et al 9 , who found that poverty could contribute to the onset, exacerbation and handling of asthma. Regarding etiology, this aspect is contrary to the hygiene theory, which argues that less favored people are exposed to more microbial agents and, therefore, less susceptible to developing the disease.…”

Introduction:Asthma is a chronic disease of the airways, which is increasing its prevalence among teenagers recently. The trigger-related factors are numerous, including environmental factors, genetic, food among others.Objective: Investigate the prevalence of asthma symptoms and possible risk factors in adolescents.Methods: This is a cross-sectional, descriptive and quantitative study conducted in 104 adolescents aged between 13 to 14 years old of both sexes from four educational institutions: three private and one public. Participants answered two questionnaires: one on risk factors for allergic diseases (EISL) and the other on asthma symptoms (ISAAC asthma module).Results: 104 adolescents answered the questionnaire: 54.8% girls and 45.2% boys. Male subjects had the most active asthma (64%) than female (20%) (p = 0.01) and also had more physician-diagnosed asthma (34.4%) than girls (6.1%) (p = 0.04), more wheezing after exercise (34.4%; 12.1%) (p = 0.03). Regarding the association between the symptoms and the risk factors we observed a statistically significant relationship between the presence of wheezing and hospitalization for public schools girls (p = 0.05). Conclusion:There is a higher prevalence of asthma symptoms in males than in females unlike other studies was observed. Why this study was made?The study was developed because the prevalence of asthma symptoms are high among adolescents and over the years other risk factors have been associated with its exacerbation. What researchers have done and found?The researchers investigated possible risk factors related to the onset of asthma symptoms in adolescents and noted that male volunteers had more active asthma than volunteers, also had more asthma diagnosed and wheezing after exercise. With regard to the association between symptoms and risk factors, a statistically significant relationship was observed between the presence of wheezing and hospitalizations for girls from public schools. What the results mean?Although the female gender suffered from hormonal changes during adolescence, it was observed that asthma symptoms were more prevalent in males. It is also worth noting that the volunteers from the public school system showed an association of risk factors with hospitalization, suggesting that the socioeconomic factor may have a greater influence on the prevalence of asthma symptoms than hormonal changes.

“…Previous studies have reported conflicting results on the relationship between poverty and asthma among children [55]. Some studies have reported a higher prevalence of asthma among less privileged children compared to privileged children [56,57] while others have reported no association between poverty and childhood asthma [58,59]. The use of different measures of poverty from one study to another may explain in part this incongruence.…”

Longitudinal patterns of poverty and health in early childhood: exploring the influence of concurrent, previous, and cumulative poverty on child health outcomes

BackgroundAlthough the links between poverty and health have often been studied , the dynamics of poverty and physical health in early childhood remain under-investigated. In particular, it is not known whether the health of young children is affected differently from that of adults by patterns of poverty unique to them.MethodsWe examined patterns of health from 5 to 41 months of age as a function of concurrent, lagged, and chronic exposure to insufficient income. Using data from the first four rounds of the Quebec Longitudinal Study of Child Development, we performed multilevel logistic and multilevel Poisson regressions and latent growth curve analyses to explore associations between exposure to poverty and mother-reported asthma-like attacks, and maternal perception of health status controlling for neonatal, maternal, and environmental characteristics.ResultsThe mean number of mother-reported asthma-like attacks significantly decreased as children aged. The likelihood of being perceived in a poorer health status also decreased across time. Concurrent poverty was associated with more mother-reported asthma-like attacks and with a higher risk of being perceived in poorer health status. One-period-lagged poverty was associated with more mother-reported asthma-like attacks and this remained significant after controlling for concurrent poverty. The number of mother-reported asthma-like attacks was significantly higher among children in the chronic poverty class compared to those in the never-poor class, particularly at 17 and 29 months. Perceived health status at 5-months was significantly poorer among chronically poor children compared to never-poor children.ConclusionExposure to poverty negatively affects two major health indicators in early childhood – maternal perception of child health and mother-reported asthma-like attacks. Patterns of the effects vary according to timing and duration of poverty exposure. Further longitudinal research is warranted to disentangle time-specific from cumulative effects of poverty on child health.

Wheezing is highly prevalent in Brazil, with variations in rates and risk factors between the regions of the country. This cross-sectional study aimed to analyze the prevalence of wheezing in children under 5 years of age (n = 733) in Cuiabá, Mato Grosso State, Brazil. The study used a brief version of the standardized instrument from the International Study of Wheezing in Infants (EISL). Analysis of factors associated used logistic regression with a hierarchical approach. Prevalence of wheezing in the previous 12 months was 43.2%. Factors associated with wheezing were: lack of at least 6 months of breastfeeding (adjusted OR = 1.91; 95%CI: 1.18-3.06), diagnosis of asthma in the family (adjusted OR = 2.02; 95%CI: 1.06-3.87), current respiratory infection (adjusted OR = 1.81; 95%CI: 1.05-3.14), and male gender (adjusted OR = 1.50; 95%CI: 1.07-2.11). The study concludes that prevalence of wheezing is high among children in this age bracket in Cuiabá and is associated with factors related to allergy, current respiratory infection, and male gender.

Baixa renda como fator de proteção contra asma em crianças e adolescentes usuários do Sistema Único de Saúde

Abstract: Poverty is not protective against asthma in children and adolescents treated via the Brazilian Unified Health System, as we might suppose based on the hygiene hypothesis. However, cohort studies are needed in order to confirm these findings.
