| Resumo: |
The prevalence of uncontrolled and controlled asthma, and the factors associated with uncontrolled asthma were investigated in a cross-sectional study. Patients aged 11 years with confirmed asthma diagnosis were recruited from the outpatient asthma clinic of Hospital de Clínicas de Porto Alegre, Brazil. Patients were excluded if they had other chronic pulmonary disease. They underwent an evaluation by a general questionnaire, an asthma control questionnaire (based on the 2006 Global Initiative for Asthma guidelines), assessment of inhaled device technique and pulmonary function tests. Asthma was controlled in 48 of 275 patients (17.5%), partly controlled in 74 (26.9%) and uncontrolled in 153 (55.6%). In the univariate analysis, asthma severity was associated with asthma control (P < 0.001). Availability of asthma medications was associated with asthma control (P = 0.01), so that most patients who could purchase medications had controlled asthma, while patients who depend on the public health system for access to medications had lower rates of controlled asthma. The use of inhaled corticosteroid was lower in the uncontrolled group (P < 0.001). Logistic regression analysis identified three factors associated with uncontrolled asthma: severity of asthma (OR = 5.33, P < 0.0001), access to medications (OR = 1.97, P = 0.025) and use of inhaled corticosteroids (OR = 0.17, P = 0.030). This study showed a high rate of uncontrolled asthma in patients who attended an outpatient asthma clinic. Severity of asthma, access to medications and adequate use of inhaled corticosteroids were associated with the degree of asthma control.
