Sleep health of assisted-living residents

Official title: Understanding the Association Between Sleep Quality, Physical Activity, and Memory in Assisted-Living Residents

Run by University of Calgary · NCT04400617 · Data updated 2026-11-12

This project tries to see if sleep quality is linked with physical activity, functional ability, and memory in older adults living in assisted-living facilities.

Is this trial a fit for you?

Likely a good fit

Ideal participants are ambulatory assisted-living residents who are relatively cognitively intact (CPS 0–3), speak English, have life expectancy greater than one year, and are inactive (<3 sessions/week of vigorous exercise).

Probably not a fit

Patients with severe cognitive impairment (CPS >3), terminal illness, non‑English speakers, wheelchair-dependent residents, or those with medical/neurological conditions that would confound cognitive testing are unlikely to benefit or be eligible.

What this trial studies

This cross-sectional feasibility study recruits inactive assisted-living residents and uses overnight polysomnography, wrist actigraphy, and sleep questionnaires to objectively measure sleep quality. Participants complete functional and physical tests plus cognitive testing (including the MoCA and memory-focused assessments) to examine links between sleep, activity, and cognition. The protocol includes a comparison group of community-dwelling older adults of similar age and cognitive status to contextualize findings. The primary aim is to test whether polysomnography and actigraphy can be feasibly implemented in assisted-living settings and to explore associations among sleep, functional capacity, and memory performance.

Why it matters

Potential benefit: If successful, this work could improve detection of sleep disorders in assisted-living residents and guide targeted activities or treatments that may slow or delay cognitive decline.

How similar studies have gone: Community-based studies have linked activity, sleep, and cognition, but applying overnight polysomnography and actigraphy specifically in assisted‑living residents is largely untested and represents a novel feasibility effort.

Show full inclusion / exclusion criteria
Inclusion Criteria:

* 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 Criteria:

* 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.
