Primary family caregivers of patients with dementia often experience high caregiver burden and significant decline in a range of health outcomes. The current study examined the relationship between medical comorbidities of inpatients with dementia and caregiver burden in adult–child primary caregivers, and the buffering effect of having a secondary caregiver on the relationship between patients' comorbidities and caregiver burden. The study is a secondary analysis of data from a cross‐sectional observational study design.
