Background: Poor adherence to inhaled corticosteroids (ICS) is a critical risk factor contributing to asthma morbidity among low-income minority adolescents.
Objective: This trial tested whether peer support group meetings and peer asthma messages delivered via mp3 players improved adherence to ICS.
Methods: Low-income African American and/or Hispanic adolescents, ages 11-16 years old, with persistent asthma, and poor (≤ 48%) adherence to prescription ICS during the 3-week run-in were randomized to intervention or attention control groups (ATG) for the 10-week treatment. During treatment, the intervention arm subjects participated in weekly coping peer group support sessions and received mp3 peer-recorded asthma messages that promoted adherence. The ATG participated in weekly meetings with a research assistant and received an equivalent number of mp3 physician-recorded asthma messages. Adherence was measured by using self-report and the Doser CT, an electronic dose counter. The primary outcome was the difference in adherence at 10 weeks between the 2 arms.
Results: Thirty-four subjects were randomized to each arm. At 10 weeks, no statistical difference in objectively measured adherence could be detected between the 2 arms when adjusting for baseline adherence (P = .929). Adherence declined in both groups over the course of the active treatment period. In both study arms, self-reported adherence by participants was significantly higher than their objectively measured adherence at week 10 (P < .0001).
Conclusion: Improving medication adherence in longitudinal studies is challenging. Peer support and mp3-delivered peer asthma messages may not be of sufficient dose to improve outcomes.
