Summary
Assisted living residents who have sleep disturbances are at great risk of developing cognitive impairments. The identification of factors that increase sleep problems in this population is the first step towards improving sleep disorders and reducing and/or delaying the occurrence of cognitive impairments in this population. Physical activity has been proposed to improve sleep quality in older individuals, but there is currently no scientific evidence of how sleep mediates the relationship between physical activity and cognition in assisted living residents. This is a cross-sectional study that investigates the relationship between sleep quality, functional/physical capacity, and cognitive performance. Participants will be recruited through a non-probabilistic sampling method (convenience) as this is a feasibility study that aims to identify, for the first time, sleep disorders in assisted living residents using objective measures of sleep. Sleep quality will be measured with polysomnography, actigraphy, and questionnaire. Functional and physical capacity will be assessed through walking tasks and actigraphy. Cognitive tasks will be used to assess memory. This study will bring new insights into the factors that affect the quality of life and sleep in assisted living residents. The evidence-based knowledge acquired on-site will be translated and shared with the local and global scientific community to raise awareness of the factors that contribute to increasing institutionalization and dependent living. Results obtained from objective and subjective measures of sleep will be of great importance to develop specialized clinical expertise and behavioral interventions that will meet residents' needs.
Eligibility
Inclusion Criteria2
- Be inactivity, which will be defined as an engagement in < 3 sessions/week of 20 min or more of vigorous exercise;
- Be able to move independently without the assistance of a wheelchair.
Exclusion Criteria7
- Diagnosis of a developmental handicap;
- Residents who are not able to understand communication and be understood by others and do not have decision-making capacity according to the Cognitive Performance Scale (CPS) > 3; The investigators will assess all the resident's capacity with the Brenda Strafford Foundation caregivers, even if their CPS is within the range included in the study (CPS 0-3);
- Terminal illness (life expectancy < 1 year);
- Not fluent in English;
- Currently participating in another trial;
- Comorbid medical or neurological illnesses (e.g., multiple sclerosis) that would confound cognitive assessments or make trial completion unlikely (in the site investigator's opinion);
- Contraindication for the tests.

Interventions
The first visit will consist of screening measurements. Participants will be asked to complete the following questionnaires: InterRAI Self Report Quality of Life Survey for Long Term Care Facilities (interRAI SQoL), Resident Assessment Instrument (RAI)-MDS 2.0, Global Physical Activity Questionnaire (GPAQ), Memory Complaint Questionnaire (MAC-Q), and Pittsburgh Sleep Quality Index (PSQI). At the end of this visit, the participants will be asked to wear the ActiWatch-2 (AW-2) as a wristwatch for 14 days. In the second visit, participants' height and weight will be measured and the participants will perform the following cognitive and functional tests: MoCA, Brief Visuospatial Memory Test-Revised (BVMT-R), Hopkins Verbal Learning Test-Revised (HVLT-R), Time up and Go (TUG), and Cognitive TUG (TUGcog). Finally, visit 3 will consist of on-site PSG recordings.
