“…Outros trabalhos na literatura analisaram a frequência de indivíduos com asma para cada questão definida como indicadora de maior gravidade. Os poucos estudos que definiram um único critério de gravidade através da associação de respostas às perguntas do ISAAC, como fizemos, encontraram uma frequência de asma "mais grave" variando de 24,7 a 30% 8,16 . No entanto, esses estudos consideraram a presença de mais de quatro exacerbações de asma no último ano como um dos parâmetros de gravidade, o que diferiu do nosso critério.…”

Objective: To estimate the distribution of asthma severity in a population-based sample of children from Salvador, Brazil.Methods: An epidemiologically oriented questionnaire (International Study of Asthma and Allergies in Childhood, ISAAC) and a questionnaire based on criteria used in clinical practice (The Global Initiative for Asthma, GINA) were administered simultaneously to 417 children aged 5 to 12 years who reported symptoms of asthma in the past 12 months. According to the ISAAC instrument, children were classified into severe and non-severe asthma, whereas GINA clinical criteria produced four categories of severity: intermittent, mild persistent, moderate persistent and severe asthma.Results: Ninety children reported symptoms indicative of severity according to the ISAAC questionnaire. According to GINA criteria, 143 children had intermittent asthma, 160 mild persistent, 51 moderate and 43 severe asthma. Agreement between the two instruments was 81.3% (kappa = 0.5). Conclusions:Most asthmatic children in the Salvador urban area have persistent asthma. Agreement between epidemiological and clinical classifications of asthma severity was satisfactory.J Pediatr (Rio J). 2010;86(5):417-423: Asthma, severity, questionnaire, child.

“…Na literatura, é descrito que o sobrepeso/obesidade é um fator de risco para uma maior incidência de asma, principalmente no sexo feminino 22 . De um modo geral, adolescentes asmáticos apresentam sobrepeso mais frequentemente do que controles sadios 23,24 . Kushinir 25 encontrou uma associação positiva entre adolescentes obesos de 13 e 14 anos e sintomas de asma (OR = 1,51; IC95% 1,07-2,13).…”

Objective: To assess the quality of life (QoL) of asthmatic adolescents and its association with asthma severity, chronic diseases, and life style. Method:Cross-sectional study involving 210 female and male asthmatic adolescents between 12 and 21 years old. The Paediatric Asthma Quality of Life Questionnaire, a self-administered instrument, was used. Explanatory variables were: allergic diseases, use of medication, passive smoking, occupational status, asthma severity, and life style. The analyses considered the dichotomous outcome (good/poor QoL) based on the mean scores. Generalized linear models (log-binomial) were used to calculate the crude and adjusted prevalence ratios.Results: Forty-six per cent of the girls and 57% of the boys had poor QoL. There was not correlation between chronic diseases and poor QoL. Low educational level, use of medication, passive smoking, and occupational factors had a statistically significant association (p < 0.05) with poor QoL. The adjusted analysis showed that severe asthma (PR = 1.53; 95%CI 1.12-2.11), use of medication (PR = 1.58; 95%CI 1.09-2.28), having asthma diagnosis established less than 5 years ago (PR = 1.30; 95%CI 0.97-1.86), passive smoking (PR = 1.38; 95%CI 1.35-2.00), and being employed (PR = 1.30; 95%CI 0.96-1.74) were associated with poor QoL. Conclusion:A multidisciplinary team needs to face the challenge of providing good QoL with the purpose of making these patients better adapted to society and to their own needs.J Pediatr (Rio J). 2009;85(6):523-530: Quality of life, asthma, adolescents, chronic disease. ResumoObjetivo: Avaliar a qualidade de vida (QV) de adolescentes asmá-ticos e sua associação com a gravidade da asma, doenças crônicas e estilo de vida.Método: Estudo seccional em 210 adolescentes asmáticos entre 12 e 21 anos de ambos os sexos. Utilizou-se questionário autopreenchível, o Paediatric Asthma Quality of Life Questionnaire. Variáveis explicativas: doenças alérgicas, uso de medicamentos, fumo passivo, trabalho, gravidade da asma e estilo de vida. As análises consideraram o desfecho dicotômico (QV boa/ruim) a partir da média dos escores. Modelos lineares generalizados (log-binomial) foram utilizados para o cálculo de razões de prevalência (RP) brutas e ajustadas.Resultados: Quarenta e seis por cento das meninas e 57% dos meninos apresentavam uma QV ruim. Não houve correlação entre doenças crônicas e QV ruim. Escolaridade baixa, uso de medicamentos, fumo passivo e trabalho tiveram relação estatisticamente significativa (p < 0,05) com QV ruim. A análise ajustada mostrou que asma grave (RP = 1,53; IC95% 1,12-2,11), uso de medicação (RP = 1,58; IC95% 1,09-2,28), ter menos de 5 anos de diagnóstico de asma (RP = 1,30; IC95% 0,97-1,86), fumo passivo (RP = 1,38; IC95% 1,35-2,00) e estar trabalhando (RP = 1,30; IC95% 0,96-1,74) se associavam a QV ruim. Conclusão:A equipe multidisciplinar necessita enfrentar esse desafio que é manter a boa QV, visando a uma melhor adequação desse paciente à sociedade e a ele próprio.J Pediatr (Rio J). 2009;85(6):...

“…Its worldwide prevalence is 7.2%, and the prevalence observed in the study population (5.6%), using the methods described above, came close to this number. 7,10,13 With increasing prevalence of both obesity and asthma, a possible relationship between them has been hypothesized. The existence of possible genetic, biological and physical mechanisms (like gastroesophageal reflux) or chemical mechanisms (inflammatory substances like tumor necrosis factor alpha, leptin or adiponectin) that are common to asthma and obesity has been observed.…”

“…5 Recent studies have attempted to demonstrate an association between obesity and asthma, which is a highly prevalent chronic infl ammatory illness (7.2% of the world's population are asthmatic). [6][7][8][9][10] Some studies have demonstrated that reductions in body mass index (BMI) among patients with asthma improve their pulmonary function, asthma symptoms, morbidity and state of health. 7 BMI has been found to be a signifi cant prognostic factor for atopy and allergic symptoms among teenage girls.…”

CONTEXT AND OBJECTIVE: Obesity and asthma are serious and growing problems. Since adipose tissue produces inflammatory substances, the aim of this study was to estimate the prevalence of asthma among students at schools in São José do Rio Preto (Phase 1), and to corroborate the hypothesis for an association between obesity and asthma among these students (Phase 2). DESIGN AND SETTING: Cross-sectional study at Faculdade de Medicina de São José do Rio Preto (Famerp). METHODS: The study consisted of two successive and dependent stages. Phase I was a cross-sectional study on 4103 randomly selected students (13-14 years old), to determine the prevalence and severity of asthma. Phase II was an analytical cross-sectional study on 431 students (190 asthmatics and 231 non-asthmatics) from Phase I, to evaluate the hypothesis of an association between obesity measured by the body mass index (BMI) and asthma. To diagnose asthma and obesity, the criteria of the International Study of Asthma and Allergies in Childhood (ISAAC) and the chart from the Centers for Disease Control (CDC; 2000) were used. The data were analyzed using Student's t test. RESULTS: We found that 5.6% of the students analyzed in Phase I were asthmatic. The BMI among the asthmatic students (21.84 kg/m²) was higher than the BMI among the non-asthmatics (21.73 kg/m²), although the p value was 0.766. CONCLUSION: In our study group, we did not find any association between increased BMI and the prevalence of asthma.
