Summary

This study is enrolling eligible participants that have high blood pressure. Reducing dietary salt intake and engaging in regular physical activity is known to decrease blood pressure in people with hypertension. This trial will determine whether a smartwatch and a mobile health application, which together deliver notifications, can increase activity levels and reduce salt intake for people with high blood pressure. All study activities will be completed online or via a mobile medical application. Participants will not have any face-to-face visits with the study team.

Interventions

Type	Name	Description
BEHAVIORAL	Dietary and physical activity JITAI delivered through the myBPmyLife app	A Fitbit smartwatch and home blood pressure monitor will be mailed to participants (in both the experimental and control arms). Participants in the intervention arm then will set up and utilize the myBPmyLife app. This app includes push notifications to promote increased physical activity and improve low-sodium food choices, establish goal setting for weekly step count and low sodium food choices, and deliver feedback on achieving the goals using a dashboard visualization within the mobile application.
OTHER	Control Group	Participants will receive the myBPmyLife app, a smartwatch, and blood pressure cuff. The myBPmyLife app will not be fully activated (as they are in the control arm). They will be provided with the option of downloading and installing a mHealth app that is publicly available. In this arm they will also perform the blood pressure monitoring, but do not receive the intervention components through the myBPmyLife app.
