Predictors of asthma control: what can we modify?

Purpose of review One strategy to improve asthma control is to identify risk factors for uncontrolled asthma in epidemiologic studies and then consider those risk factors as potential targets for intervention. This article reviews predictors of impairment based on validated tools and predictors of severe asthma exacerbations. Recent findings Indirectly modifiable risk factors for poor asthma control include older age in adults, lower socioeconomic status, and poor perception of dyspnea. Modifiable risk factors for poor asthma control include allergy triggers, low adherence, comorbidities, absence of specialty care, and various aspects of asthma self-management education. Summary Intervention strategies are suggested for predictors that are directly or indirectly modifiable. It is hoped that attention to these factors will improve asthma control and reduce the burden of disease.
