Buying Time: Improving Sleep to Promote Cognitive Function in Older Adults

Not Applicable

Completed

• Conditions: Sleep; Aging
• Interventions: Behavioral: Life Style and Sleep Intervention

• Registration Number: NCT02926157
• Lead Sponsor: University of British Columbia

Brief Summary

The purpose of this study is to investigate whether a comprehensive group education combined with a lifestyle "activation" program that includes (a) sleep hygiene course, (b) physical activity promotion, and (c) bright light therapy, can improve both sleep quality and cognitive function among 96 community-dwelling older adults.

Detailed Description

96 community-dwelling older adults with sleep complaints will be randomized into either a 6-month life style and sleep activation intervention program or a waitlist control group (participants in this group will be offered an abbreviated version of the program upon completion of the 6 month study). There are 3 measurement sessions to measure cognition, sleep, and physical activity at the onset of the study, the midway (3 month) point, and completion (at 6 months).

Arm && Interventions

Group	Intervention	Description
Life Style and Sleep Group	Life Style and Sleep Intervention	Participants randomized into this group will undergo a 4 week sleep hygiene course (classes 1x/week for 1.5 hours), followed by a 20 week lifestyle activation program. During the 20 week lifestyle activation program, participants wear a Fit Bit and receive a call from a fitness professional every other week for motivation and recommendations, and receive a bright light therapy program from a sleep expert based on their initial sleep results at the baseline measurement session.
