“…Recent studies have shown similar trends. In a smaller city from Brazil, the prevalence of wheezing and shortness of breath in the last 12 months remained stable over a ten year period [10]. The same stabilization has been described by Zollner et al in Germany, in a study conducted about current wheezing and asthma between 1992 and 2001 [11].…”

“…The prevalence of self-reported asthma in the previous year has been reported to be 4.7% ( 13 ) and 5.2%. ( 14 ) In the present study, by combining the questions regarding the diagnosis of asthma (no specific recollection period) and symptoms in the previous year, we found that 4.5% of those who were 20 years of age or older reported this condition. In addition, when analyzing that age group, we found significant differences between the genders in terms of the prevalence of asthma; this finding is consistent with those of previous studies, ( 13 , 14 ) the prevalence of asthma being higher among females (7.1% vs. 4.3%; p = 0.002).…”

“…( 14 ) However, the criteria used in those studies in order to define the outcome differ from those used in the present study, and it is therefore difficult to compare the studies in terms of the reported prevalence. The prevalence of self-reported asthma in the previous year has been reported to be 4.7% ( 13 ) and 5.2%.…”

Inhaler use in adolescents and adults with self-reported physician-diagnosed asthma, bronchitis, or emphysema in the city of Pelotas, Brazil

et al. 2013

OBJECTIVE: To evaluate the characteristics of users of inhalers and the prevalence of inhaler use among adolescents and adults with self-reported physician-diagnosed asthma, bronchitis, or emphysema. METHODS: A population-based study conducted in the city of Pelotas, Brazil, involving 3,670 subjects ≥ 10 years of age, evaluated with a questionnaire. RESULTS: Approximately 10% of the sample reported at least one of the respiratory diseases studied. Among those individuals, 59% reported respiratory symptoms in the last year, and, of those, only half reported using inhalers. The use of inhalers differed significantly by socioeconomic status (39% and 61% for the lowest and the highest, respectively, p = 0.01). The frequency of inhaler use did not differ by gender or age. Among the individuals reporting emphysema and inhaler use, the use of the bronchodilator-corticosteroid combination was more common than was that of a bronchodilator alone. Only among the individuals reporting physician-diagnosed asthma and current symptoms was the proportion of inhaler users higher than 50%. CONCLUSIONS: In our sample, inhalers were underutilized, and the type of medication used by the individuals who reported emphysema does not seem to be in accordance with the consensus recommendations.

Trend of self-reported asthma prevalence in Brazil from 2003 to 2013 in adults and factors associated with prevalence

Objectives: To determine the trend of self-reported asthma diagnosed prevalence and to describe the factors associated with asthma in Brazilian adults. Method: Epidemiological cross-sectional study based on databases analysis from three national household surveys: Pesquisa Nacional por Amostra de Domicílios (PNAD) 2003, PNAD 2008 and Pesquisa Nacional de Saúde (PNS) 2013. Participants between 18-45 years old were included. Trend analysis of asthma diagnosed prevalence was conducted using a logistic general linear model. A hierarchical logistic regression model was used to select factors significantly associated with asthma prevalence. Results: Asthma diagnosed prevalence was 3.6% (2003), 3.7% (2008) and 4.5% (2013), showing a statistically significant increased trend. Asthma diagnosed prevalence also increased when analysed by gender (annual change for men: 2.47%, p < 0.003; women: 2.16%, p < 0.001), urban area (annual change for urban: 2.15%, p < 0.001; rural: 2.69%, p = 0.072), healthcare insurance status (annual change without healthcare insurance: 2.18%, p < 0.001; with healthcare insurance: 1.84%, p = 0.014), and geographic regions (annual change North: 4.68%, p < 0.001; Northeast: 4.14%, p < 0.001; and Southeast: 1.84%, p = 0.025). Female gender, obesity, living in urban areas and depression were associated with asthma diagnosed prevalence. Discussion: PNAD and PNS surveys allow for a very large, representative community-based sample of the Brazilian adults to investigate the asthma prevalence. From 2003 to 2013, the prevalence of self-reported physician diagnosis of asthma increased, especially in the North and Northeast regions. Gender, region of residence, household location (urban/rural), obesity, and depression diagnosis seem to play significant roles in the epidemiology of asthma in Brazil.
