Adherence to asthma therapy in the preschool child.

Preschool children's adherence to asthma therapy is often sub-optimal and can result in decreased quality of life for children and parents, as well as an increased risk for dangerous asthma exacerbations. Asthma management for the preschool child presents some unique challenges to adherence to therapy, including the child's limited ability to communicate, multiple caregivers responsible for medications, and parental concerns about medications. Parent beliefs, characteristics of the regimen, and family functioning have been associated with adherence levels. Understanding and improving adherence to asthma therapy for the preschool child will necessarily require addressing these age-specific concerns.
