Abstract
Introduction Asthma control has been found to be inadequate in all populations studied to date and accounts for the majority of costs for this disease. The objective of our study was to evaluate the prevalence of poorly-controlled asthma in primary care patients and to identify some of the factors associated with this situation. Methods We conducted a transversal study that included asthmatic patients over 18 years of age who were monitored in primary care visits (n = 2159). Asthma control was evaluated using the Asthma Control Questionnaire. The demographic variables and the adherence to therapy were evaluated using a questionnaire. The OR for poorly controlled asthma was calculated using logistic regression using asthma control as the dependent variable, which was assessed using the ACQ score. Results The prevalence of uncontrolled asthma was 63.8%. Risk factors for poorly-controlled asthma were treatment with oral corticosteroids (OR = 6.55), greater severity of asthma (OR = 3.11), the presence of a recent stressful event (OR = 2.44), a lesser importance given to compliance with therapy (OR = 1.66) and living in rural areas (OR = 1.29). In contrast, sex, age, obesity, smoking, alcohol consumption and educational level did not show any influence over asthma control. Conclusions Asthma remains poorly controlled in Spain but some of the factors related to this situation could be changed by the healthcare system.
