Quality of sleep in caregiving relatives of people with dementia: investigation of the prevalence and possible predictors

Background Caregiving relatives of people with dementia (PwD) are exposed to exhausting tasks all day long. The results of a current study suggest that personality traits, sociodemographic and caregiving variables could be associated with poor sleep quality of caregivers of PwD. Nevertheless, the detailed impact of these variables on sleep quality of caregivers is still unknown. Method This study is based on secondary data from the Tele.TAnDem project. First, descriptive data of 322 caregivers were analyzed regarding prevalence rates of poor sleep quality and high rates of daytime sleepiness in comparison to non-caregivers. Second, hierarchical regression analyses were conducted to calculate the predictive effect of interpersonal and caregiving related variables on subjective sleep quality and daytime sleepiness. Results With respect to the prevalence, descriptive data indicate a poorer subjective sleep quality and higher rates of daytime sleepiness of caregivers of PwD compared to non-caregivers. Regression analyses revealed significant effects for gender, disturbed day-night rhythm, burden of caregiving, stress coping strategies and depressive symptoms regarding subjective sleep quality. The number of disturbed behavior patterns, the burden of caregiving and depressive symptoms were significantly associated with higher rates of daytime sleepiness. Conclusion Caregiving of PwD affects subjective sleep quality as well as daytime sleepiness of caregiving relatives. Both dimensions of sleep quality were associated with several personal and caregiving related variables. Chronic poor sleep quality is a high-risk factor for psychological and physical health problems and should be considered in further research and development of interventions for caregiving relatives of PwD.
