Neuropsychiatric symptoms are Predictors of Disturbed Sleep in Mexican American Caregivers

Abstract

AbstractBackgroundCaregivers of people living with dementia are more likely to experience disturbed sleep compared to non‐caregivers. Mexican‐Americans may be especially at risk due to low rates of nursing home use even in advanced dementia, when behavioral symptoms are most apparent. Few studies have evaluated predictors of disturbed sleep in this high‐risk group.MethodUsing data from the 2015 wave of the Hispanic Established Population for Epidemiologic Study of the Elderly, a representative sample of older Mexican‐Americans and their caregivers in the southwestern United States (n = 460), we examined the association of care recipient neuropsychiatric symptoms with disturbed sleep in caregivers. Care recipients’ behavioral symptoms of cognitive decline were assessed using the caregiver‐reported Neuropsychiatric Inventory. We examined caregivers’ depressive symptoms as an additional stressor. Potential “buffers” against sleep disturbances included communal support (neighbor, church, social services) and respite care. Caregivers were classified as having “highly disturbed sleep” if they reported disturbed sleep three or more days a week, and were compared to caregivers with “non‐highly disturbed sleep” (reported disturbed sleep less than three days a week). We used multivariable logistic regression to examine the association between behavioral symptoms and highly disturbed sleep, controlling for demographic factors and care buffers.ResultCaregivers in the sample were predominantly spouses or adult children of their care recipients. They had a mean age of 59.7 and7 8% were women. Care recipients were a mean age of 90 and 65% were women. Caregivers with disturbed sleep (12% of the sample) reported significantly more care recipient NPI symptoms, distress from symptoms, and more depressive symptoms. In the regression model accounting for all predictors, the number of NPI symptoms and depressive symptoms were associated with higher odds of disturbed sleep, while communal support was associated with lower odds of disturbed sleep. Use of respite care did not show associations.ConclusionBehavioral symptoms of cognitive impairment are associated with sleep disturbance in Mexican American caregivers. Though respite has been described as a crucial resource for caregiver sleep health, communal supports were more significantly associated with sleep l. These results should inform the development of culturally‐competent resources for Mexican‐Americans.
