Mobile Health Intervention to Improve Exercise in Pediatric PH
Sponsor: Vanderbilt University Medical Center
Summary
Children and adults with pulmonary arterial hypertension (PAH) have severely reduced daily activity compared to healthy populations. In adults, investigators recently demonstrated that lower baseline daily step counts associated with increased risk of hospitalization and worsening WHO functional class; similarly, reduced step counts associate with hospitalization in children with PAH. This application builds on our recently completed NIH-funded pilot mobile health (mHealth) trial in adult patients with PAH which demonstrated the ability to remotely increase step counts. The investigators now aim to: (1) adapt our mHealth intervention to the developmental needs and interests of adolescents; and, (2) determine if our intervention increases step counts in adolescents, providing the foundation for a larger trial to assess the impact on quality of life and clinical outcomes.

Our HIPPA-compliant texting platform is linked to the Fitabase Interface. Real time activity data are transmitted from the participant's smartphone to Fitabase via cellular network. Participants will receive 3-5 texts/day in sync with their preferred schedule defined at enrollment and taking into account school schedules as relevant. These texts use personal, disease-specific, and provider information to deliver two types of messages customized to the current step count and sent in equal proportion. Messages are designed to facilitate self-awareness, reinforce step targets, and link physical activity with a reward or memorable cue.
