Sleep Quality of Persons with Dementia and Family Caregivers in Korean Americans: Wearable Technology to Study the Dyadic Association
Eunae Ju, Yuqing Guo, Jung In Park, Julie Kim, Annie Qu, Jung‐Ah Lee. Western Journal of Nursing Research, 2025-03-17
Topic: Risk, prevention and care in population studies
A total of 11 dyads participated in the study. The mean age of PWD was 82.7 years (standard deviation (SD) = 2.3); of caregivers 69.1 years (SD = 10.2). Nine PWD (81.8%) were male, all caregivers (100%) were female, and 4 dyads (36.4%) slept in the same bed. Sleep parameters of PWD were significantly correlated with those of caregivers. Our findings demonstrate that PWD's sleep parameters (eg, deep sleep) were significantly correlated with those of caregivers' parameters. This study shows the feasibility of using wearable device to measure dyadic sleep quality for both PWD and their caregivers, particularly within immigrant populations.
Key findings
- A total of 11 dyads participated in the study.
- The mean age of PWD was 82.7 years (standard deviation (SD) = 2.3); of caregivers 69.1 years (SD = 10.2).
- Nine PWD (81.8%) were male, all caregivers (100%) were female, and 4 dyads (36.4%) slept in the same bed.
- Sleep parameters of PWD were significantly correlated with those of caregivers.
- Our findings demonstrate that PWD's sleep parameters (eg, deep sleep) were significantly correlated with those of caregivers' parameters.
Why it matters
In just 11 Korean American dyads, sleep parameters of people with dementia were significantly correlated with those of their family caregivers, showing that wearable devices can measure sleep in both. This is a small feasibility study and does not test any treatment, cure, or prevention for Alzheimer's disease.
