A Mobile Health Intervention to Increase Physical Activity in Pulmonary Arterial Hypertension.

ABSTRACT:

Background

Supervised exercise training improves outcomes in patients with pulmonary arterial hypertension (PAH). The effect of an unsupervised activity intervention has not been tested.

Research question

Can a text-based mobile health intervention increase step counts in patients with PAH?

Study design and methods

We performed a randomized, parallel arm, single-blind clinical trial. We randomized patients to usual care or a text message-based intervention for 12 weeks. The intervention arm received three automated text messages per day with real-time step count updates and encouraging messages rooted in behavioral change theory. Individual step targets increased by 20% every 4 weeks. The primary end point was mean week 12 step counts. Secondary end points included th
