eFHS Messaging Trial

Summary

In this research the investigators will develop and test an innovative scalable mobile health and digital cardiovascular monitoring system within a longitudinal deeply characterized cohort with three components: 1) smartphone application (app) designed to promote adherence, integrate digital and mHealth information, and facilitate communication with participants and researchers; 2) smartwatch activity monitoring using the Apple iWatch; and 3) home blood pressure (BP) monitoring using the Withings blood pressure device.

The objective of the messaging trial is to test the effect of messaging strategies on improving participants' long-term use of and engagement with our selected mobile health technologies and on increasing response rate of survey data collection.
