ABSTRACT

Background:

New models of scalable population-based data collection that integrate digital and mobile health data are necessary.

Objective:

To describe a cardiovascular digital and mobile health e-cohort embedded in a traditional longitudinal cohort study, the Framingham Heart Study (FHS).

Methods:

We invited eligible and consenting FHS Generation 3 and Omni participants to download the eFHS app onto their smartphones and co-deployed a digital blood pressure (BP) cuff. Soon thereafter, participants were also offered a smartwatch (Apple Watch). Participants are invited to complete surveys through the eFHS app, to perform weekly BP measurements and to wear the smartwatch daily.

Results:

Up to July 2017, we have enrolled 790 eFHS participants, representing 75.7% of potentially eligible FHS participants. eFHS participants were, on average, 538 years of age and 57% were women. 85% (n=675) of eFHS participants completed all of the baseline survey and 59% (n=470) completed the 3-month survey. 42% (n=241 of 573) and 76% (n=306 of 405) of eFHS participants adhered to weekly digital BP and HR uploads, respectively over 12 weeks.

Conclusions:

We have designed an e-cohort focused on identifying novel CVD risk factors using a new smartphone app, a digital BP cuff, and a smartwatch. Despite minimal training and support, preliminary findings over a 3-month follow-up period show that uptake is high and adherence to periodic app-based surveys, weekly digital BP assessments, and smartwatch HR measures is acceptable.
