Factors Associated with Older Adults' Long-Term Use of Wearable Activity Trackers.

Background: Wearable activity trackers (WATs) have the potential to improve older adults' health; yet, many adopters of WATs are not able to use them on a long-term basis. Methods: A survey was conducted with an online panel of adults 65 and older (N = 214) to explore factors associated with long-term use of WATs, including initial adoption motivations, usage patterns, as well as differences in sociodemographic factors, health status, and activity levels. Results: Results from the logistic regression analysis indicated that being a long-term WAT user was significantly associated with using a wider variety of WAT functions, wearing WAT every day, being female, exercising more frequently, having higher education, not engaging in step count competition, and not having chronic conditions. Conclusions: Understanding long-term use of WATs among older adults is important given that this technology is prone to be abandoned quickly after initial adoption and such abandonment negates its potential in supporting long-term health behavior change. Findings of this study will inform innovative WAT designs that afford long-term use and offer helpful strategies for future interventions using WATs among older adults.
