Sedentary behavior has been associated with adverse health outcomes such as disturbed sleep in older adults. We conducted a single-group pretest and posttest study to evaluate the feasibility of a personalized behavioral intervention program using mobile health technology in improving physical activity and sleep in older adults. The four-week intervention included: personalized physical activity training, real-time physical activity self-monitoring, interactive prompts and feedback with a smartwatch, phone consultation with an exercise trainer and research team members, and weekly financial incentives for achieving weekly physical activity goals. Eight cognitively intact older adults were recruited and completed the study. Findings suggested that the intervention was feasible in this sample of older adults and provided favorable changes in levels of physical activity during the intervention and at post-intervention. Future studies will include a fully powered trial to evaluate the efficacy of this intervention in sedentary older adults.
