Background: This study aimed to examine the difference of
sleep quality between family members of dementia
patients and general population in community.
Methods: Participants (n=215,676) aged 19 years and over in
the 2018 Korea Community Health Survey were
classified into three groups; family members living at home
with a person with dementia (FHD; n=2,445), family
members living separately from a person with dementia
(FSD; n=9,132), and family members without a person
with dementia in the family (FwoD; n=204,099). The
Pittsburgh Sleep Quality Index greater than 6 points was
regarded as poor sleep quality (PSQ). Multiple logistic
regression analysis was used to explore the associa-
tions between living with dementia patients and PSQ.
Results: The prevalence of PSQ was 48.3% in FHD, 40.7% in
FSD, and 38.8% in FwoD. After adjusting for po-
tential confounders, compared to FwoD, the odds ratio for
PSQ was 1.42 (95% confidence interval [CI],
1.31-1.54) in FHD and 1.22 (95% CI, 1.17-1.27) in FSD.
Additionally, almost all age- and sex-stratified family of
dementia patients, except for the youngest (<40 years) men
of FHD and the youngest (<40 years) men of FSD,
had a higher risk for PSQ than FwoD.
Conclusions: Both FHD and FSD have lower sleep quality
than FwoD. Public psychological interventions and
supports are needed to family members of dementia patients
in the community.
