Sleep quality differences among caregivers for persons living with and without dementia.

Objectives: This study examined the relationship between caring for a person with/without dementia and caregiver sleep quality, and analyzed the extent to which perceived benefits of caregiving and assessments of caregiver-recipient relationship quality explain the relationship between care recipient dementia status and caregiver sleep quality.

Method: Data were analyzed from caregivers for persons with no or probable dementia who participated in the 2017 National Study of Caregiving (NSOC) and National Health and Aging Trends Study. Caregiver sleep quality was measured using NSOC time diary interview. Perceptions of caregiving and relationship quality were assessed using 4-item surveys. We used multivariable logistic regressions to examine the association between care recipient dementia status and caregiver sleep quality controlling for covariates.

Results: The sample consisted of 1,374 caregivers (mean age = 62.3, SD = 14, 68.3% women, 69.4% non-Hispanic White). In multivariable models adjusting for caregiver and care recipient characteristics, being a caregiver for someone with dementia was associated with 23% lower odds of reporting "excellent/very good" sleep quality (OR: 0.77, 95%CI: 0.61-0.98, p = 0.032). Greater perception of caregiving benefits was associated with 8% greater odds of "excellent/very good" sleep quality (AOR: 1.08, 95%CI: 1.02-1.15, p = 0.013), but did not explain the relationship between dementia and caregiver sleep quality. Positive ratings of relationship quality explained the relationship between care recipient dementia status and caregiver sleep quality (AOR: 0.82, 95%CI: 0.65-1.05, p = 0.12).

Conclusion: Improving assessments of relationship quality and amplifying perceptions of caregiving benefits may reduce disparities in sleep quality between caregivers of persons living with or without dementia.
