A Personalized Behavioral Intervention to Improve Physical Activity, Sleep and Cognition in Sedentary Older Adults
Cognitive decline and sleep complaints are prevalent in older adults and severely affect older adults' physical health and quality of life. 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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Intervention
Based on the self-efficacy theory, participants in the intervention arm will receive personalized, circadian-based activity guidelines, a 2-hour in person education session, real time physical activity self-monitoring, interactive prompts, biweekly phone consultation with the research team, and financial incentives for achieving weekly physical activity goal.
|
In-person training with the exercise trainer ( 3 sessions for participants without cognitive impairments over 24 weeks & 4 sessions for older adults with mild cognitive impairment over 16 weeks).
Self-monitoring level of physical activity (steps & minutes of moderate activity) using the smart watch. .
The Google calendar and Fitbit apps will send messages and alerts to the subject's smart watch that encourage subjects to achieve subjects' daily goals.
If a participant has low activity for 3 consecutive days, the research assistant will call the participant to either encourage the participant to adhere to the plan or provide a modified plan after consulting the exercise trainer.
Phone consultation: Subjects will have biweekly phone consultation with the research team members to receive guidance and adjustment on activity plans.Financial incentives: when the daily activity goal is achieved for more than four days per week, a $5 reward will be given to subjects.
|
Placebo Comparator: Control
The control group will receive general education on physical activity for older adults and continue daily activity and healthcare routine.
Participants in this group will also receive a Go4Life program book from the National Institute on Aging.

Measure Description |
Time Frame |
---|---|---|
Change in Objective Sleep Duration
Time Frame: Week 1, Week 26 intact cognition or Week 18 for mild cognitive impairment (MCI)
|
Total Sleep time (minutes) will be measured using actigraph
|
Week 1, Week 26 intact cognition or Week 18 for mild cognitive impairment (MCI)
|
Change in Sleep Efficiency as Assessed by Actigraphy
Time Frame: Week 1, Week 26 intact cognition or Week 18 for MCI
|
Sleep efficiency (reported as a percentage) will be measured using actigraphy
|
Week 1, Week 26 intact cognition or Week 18 for MCI
|
Change in Subjective Sleep Quality as Assessed by the Pittsburgh Sleep Quality Index (PSQI)
Time Frame: Week 1, Week 26 intact cognition or Week 18 for MCI
|
The PSQI, seven component scores are derived, each scored 0 (no difficulty) to 3 (severe difficulty).
The component scores are summed to produce a global score (range 0 to 21).
Higher scores indicate worse sleep quality.

The composite cognition score is the primary cognition measure used to measure global cognitive function.
The score will range from 0-400, with a higher score indicating higher performance.
