Abstract:

Smartwatch use declines overtime in mobile health research. We aimed to evaluate the distinct temporal patterns of watch use behaviors over one year and examine its association with longitudinal physical activity levels in the electronic Framingham Heart Study (n=1185; mean age 53, SD 9 years; 59% women). We defined weekly watch use as the number of days that participants wear the watch ? 5 hours. We identified three distinct watch use patterns using k-means clustering; ~ 42% of participants sustained a daily use pattern over one year (daily users), late lapsers (20%) who had engagement of 26 weeks, and early lapsers (38%) who had the lowest frequency of weekly watch use (8 weeks). Daily users were more likely to be older, reported excellent health and had lower scores for depressive symptoms compared to other users. Using linear mixed models, we observed that daily user was significantly associated with higher physical activity compared to early lapsers (702 steps; 95% CI, 362-1042). Late lapser was associated with higher physical activity compared to early lapsers (467 steps; 95% CI, 61-874). Thus, daily watch users are more likely to engage in physical activity than other users.
