Sociodemographic and health-related factors are associated with long-term use of digital health devices, according to a study published in npj Digital Medicine.
Researchers followed a cohort within the long-running and ongoing Framingham Heart Study that used three digital components: a smartphone app, a blood pressure cuff and a smartwatch.
Participants received app-based surveys at enrollment and every three months. Step count and heart rate data were collected daily from the smartwatch, while blood pressure measurements were taken weekly. During in-person exams, researchers collected sociodemographic information as well as data about health status and behaviors.
The study found that older age (55 years and above) was associated with higher use of each device over the yearlong follow-up period. Women and participants with higher levels of education were more likely to complete the app surveys. Higher scores for depressive symptoms and lower-than-excellent self-rated health were linked to lower smartwatch use.
