Adherence with physical activity monitoring wearable devices in a community-based population: observations from the Washington, D.C., Cardiovascular Health and Needs Assessment
- 265 Downloads
Wearable mobile health (mHealth) technologies offer approaches for targeting physical activity (PA) in resource-limited, community-based interventions. We sought to explore user characteristics of PA tracking, wearable technology among a community-based population within a health and needs assessment. In 2014–2015, we conducted the Washington, D.C., Cardiovascular Health and Needs Assessment in predominantly African-American churches among communities with higher obesity rates and lower household incomes. Participants received a mHealth PA monitor and wirelessly uploaded PA data weekly to church data collection hubs. Participants (n = 99) were 59 ± 12 years, 79% female, and 99% African-American, with a mean body mass index of 33 ± 7 kg/m2. Eighty-one percent of participants uploaded PA data to the hub and were termed “PA device users.” Though PA device users were more likely to report lower household incomes, no differences existed between device users and non-users for device ownership or technology fluency. Findings suggest that mHealth systems with a wearable device and data collection hub may feasibly target PA in resource-limited communities.

We would like to acknowledge the participating church communities for warmly welcoming our research team and providing feedback from preliminary stages. Additionally, we acknowledge the D.C. CHOC for their contribution to the study design and their insightful recommendations. We would like to acknowledge Ms. Darlene Allen for her work with blood testing for the study.
We would also like to acknowledge the work on this project by Mr. Praduman Jain and colleagues from Vignet Corporation through use of their Precision Medicine Initiative (PMI) toolkit under contract #HHSN268201400023P. The PMI toolkit enables custom mHealth programs for data collection, population surveillance, interactive informed consent, assessments, remote monitoring, CBPR, consumer engagement, interventions, motivation, and behavior change.
