Asthma is a common chronic illness of childhood that requires coordinated efforts by children, families, and health care professionals for proper medical management. The medical management of pediatric asthma involves pharmacological and behavioral recommendations to both prevent and control asthma attacks. However, management of these attacks is hindered by failure to adhere to the prescribed recommendations. While the literature on adherence in pediatric asthma has grown over the past 10 years, few definitive statements can be made about causes and treatment. Various issues related to adherence and pediatric asthma are reviewed in this paper, including assessment methods, factors influencing adherence, and treatment strategies. Recommendations for future research are provided, starting with more controlled randomized studies.
