Sedentary lifestyle, which is reported by 90% of older Americans, is an important risk factor for both cognitive decline and sleep disturbances. Although promoting physical activity has benefits to older adults' health, including sleep and cognition, traditional interventions to increase activity are challenging due to extensive staffing requirements and low adherence. Electronic activity monitors, such as wrist-worn accelerometers, can track heart rate, activity, and sleep to allow individuals to work towards personal activity and sleep goals. These appealing features make these devices ideal for interventions that aim to change behaviors and improve health outcomes. However, the efficacy of using electronic activity monitors to promote physical activity and health in older adults has not been examined. The investigators will conduct a randomized controlled trial in a cohort of older adults (without dementia) with both sedentary lifestyle and nocturnal sleep complaints to examine the effectiveness of a personalized behavioral intervention (compared to a control group) embedded within a smart watch application in older adults. 94 cognitively intact elders and 21 older adults with mild cognitive impairment will be enrolled and randomly allocated to the intervention or control group. Participants in the intervention arm will receive in person exercise training sessions, and personalized, self-monitor physical activity, receive interactive prompts, biweekly phone consultation with the research team, and financial incentives for achieving weekly physical activity goals. The control group will receive general education on physical activity in older adults and continue the routine daily activity during the intervention period. The intervention for older adults without cognitive impairment is 24 weeks and for older adults with mild cognitive impairment is 16 weeks.","overall_status":"Completed","phases":["PHASE1","PHASE2"],"study_type":"INTERVENTIONAL","sponsor":"Johns Hopkins University","enrollment":129,"countries":["United States"],"start_date":"2019-07-11","completion_date":"2023-02-28","last_update_date":"2023-03-08","source_url":"https://clinicaltrials.gov/study/NCT03959202","editorial_summary":"A registered PHASE1, PHASE2 study indexed because it matched monitored longevity research terms.
