Prevalência de chiado no peito em adultos da coorte de nascimentos de 1982, Pelotas, RS

Abstract

OBJECTIVE:To estimate the prevalence of wheezing in the chest among adults, and to explore the effect of some variables on the prevalence of this condition. METHODS:This was a prospective cohort study on individuals born in the city of Pelotas (Southern Brazil) in 1982. A total of 4,297 subjects was traced in 2004-5, representing 77.4% of the original cohort. Data were collected by means of interviews using the ISAAC (International Study of Asthma and Allergies in Childhood Steering Committee) questionnaire. Associations between the outcome "occurrence of wheezing in the chest within the 12 months prior to the interview" and the variables of socioeconomic, demographic and birth characteristics were tested by means of multivariable analyses, using Poisson regression. RESULTS:The prevalence of wheezing over the preceding year was 24.9%. Among the individuals reporting wheezing, 54.6% reported diffi culty in sleeping, and 12.9% reported diffi culty in speaking due to wheezing. The prevalence of wheezing in the chest was signifi cantly higher among women. This association was maintained in analyses adjusted for non-white skin color, family history of asthma and low socioeconomic level. Among men, there was no signifi cant association in the analyses adjusted for skin color and family income at birth. Family histories of asthma and poverty throughout life presented signifi cant associations with wheezing in the chest. For both sexes, there were no associations with the variables of birth weight and breastfeeding duration. CONCLUSIONS:The prevalence of wheezing in the chest was high, and subjects with low family income at birth were more likely to have had wheezing in the chest over the preceding year.

Chronic respiratory diseases and respiratory symptoms after a mining dam rupture: Brumadinho Health Project

“…Adults with higher level of education were less likely to report wheezing. This relationship between worse socioeconomic status and greater reporting of respiratory symptoms has already been observed in other Brazilian studies and demonstrates that worse socioeconomic conditions tend to increase the population's vulnerability to these symptoms, perhaps due to greater exposure to risk factors: smoking habit, low level of education, and occupational exposure to dust 4,17 . Conversely, the greater chance of reporting wheezing among former and current smokers demonstrates the possible effects of smoking on the respiratory system, an association already well-established in the literature 1,4,15,16 .…”

“…According to the World Health Survey conducted in 2002-2003, the worldwide prevalence of this symptom in the previous 12 months among asthmatic individuals was 8.6% 12 , and Brazil was the fourth country with the highest prevalence (22.6%). Other studies conducted in Brazil among young adults showed higher prevalence (24.9% in Pelotas, state of Rio Grande do Sul, and 20.2% in Lages, state of Santa Catarina, both in the south region, and 17.9% in Cezarina, state of Goiás), but these studies also used a longer period for symptom reporting (12 months), which may have contributed to the higher prevalence of this outcome 4,17,26 .…”

“…According to the literature, air polluting agents are related to lung diseases and respiratory symptoms 11 . Although there are some studies on the prevalence of these diseases 6,[12][13][14] and respiratory symptoms 4,[15][16][17][18] , we found only one that was carried out in a mining region 14 .…”

Caesarean sections and risk of wheezing in childhood and adolescence: data from two birth cohort studies in Brazil

“…Special attention has been paid to the production of types 1 and 2 T-helper cytokines [ 18 ]. However, in addition to biological factors, the environment may play a role, and therefore, studies in low- and middle-income settings, such as ours, are desirable, mainly because, differently from what is reported in some high-income countries, asthma in Brazil is more frequent among subjects from low socio-economic groups [ 24 , 25 ]. In Pelotas, the proportion of deliveries through C-section increased from 30.5% to 45% from 1993 to 2004 [ 8 ].…”

Frequência de sintomas associados à asma em residentes do município de Diadema

“…A questão referente à afirmação de "sibilos nos últimos 12 meses", que reflete asma ativa/atual, é considerada a pergunta com resposta mais reprodutível, diminuindo os vieses de memória (Solé et al, 1998). A frequência de asma ativa baseada em sintomas de chiado, mesmo sendo um bom indicativo não constitui um diagnóstico confirmado (Menezes et al, 2008). O diagnóstico médico de asma foi avaliado indiretamente através da pergunta "Já teve asma alguma vez na vida?"…”
