The Association Between Cohabitation With Dementia Patients and Family Mental Health: Age-Stratified Findings

Dementia is a global health issue and its effects on family caregivers are substantial. This study investigated the relationship between cohabitation with patients and the mental health of families in South Korea. On the basis of the nationwide data, 24,874 individuals with dementia within their families were included in the analysis. Multivariate logistic models were used to compare the 3 mental health issues (stress, depression, and suicidal ideation) between the cohabiting and noncohabiting groups. Approximately 15% of participants cohabited with patients with dementia. Members of the cohabiting group had a more stressful status and a higher rate of suicidal ideation than those in the noncohabiting group; however, this association remained significant only for older caregivers (≥65 y). In conclusion, the mental health of family members living with patients with dementia, particularly older caregivers, should be carefully assessed.
