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

May 7, 2019 updated by: Teresa Liu-Ambrose, University of British Columbia
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.

Conditions

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).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Life Style and Sleep Group
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.
No Intervention: Wait-list Control
Participants randomized into this group will complete all measurement sessions. After completion of the final measurement session (6 months), participants will be offered an abbreviated version of the Life Style and Sleep Group intervention including the sleep hygiene course, consultation with sleep expert to go over individual sleep patterns and be given recommendations, along with physical activity recommendations from a fitness expert.
