A Mobile Health Intervention in Pulmonary Arterial Hypertension (mHealth)
We have partnered with the Vanderbilt University Medical Center as co-investigators in an ongoing study which proposes the use of a mobile health intervention to encourage increased exercise in PAH patients. The study is a randomized trial to examine the feasibility of leveraging a wearable activity tracker (Fitbit Charge HR) and a text messaging intervention to increase physical activity.
The design of this intervention was derived from our original mActive study. Personalized messages (“smart texts”) evaluate and incorporate real-time activity data from Fitbit devices in the selection of message types and content.

Interventions Against Insulin Resistance in Pulmonary Arterial Hypertension
In addition, we are also partnering with the Vanderbilt University Medical Center on a study evaluating whether interventions to prevent insulin resistance (i.e. metformin and the mActive text messaging intervention) in patients with PAH will also improve exercise capacity.

Past Studies
mActive Trial
This intervention trial showed that our automated tracking-texting intervention increased physical activity with, but not without, the texting component. Smart texts increased physical activity by about a mile per day. Learn more about the mActive Trial here: https://clinicaltrials.gov/ct2/show/NCT01917812 http://jaha.ahajournals.org/content/4/11/e002239.full We are currently performing long-term follow-up of mActive trial participants, with support from the Aetna Foundation. |
mActive-Smoke
In this observational study, supported by the American Heart Association, we used mHealth tools to study the longitudinal association of physical activity with smoking urges. Read more about the results here. |
