title: The effects of direct-to-consumer advertising on medication use among Medicaid children with asthma.
abstract: Asthma medication adherence is low, particularly among Medicaid enrollees. There has been much debate on the impact of direct-to-consumer advertising (DTCA) on health care use, but the impact on medication use among children with asthma has been unexamined. The study sample included 180,584 children between the ages of 5 and 18 with an asthma diagnosis from a combined dataset of Medicaid Analytic eXtract and national advertising data. We found that DTCA expenditure during the study period was significantly associated with an increase in asthma medication use. However, the effectiveness declined after a certain level.
