Abstract
INTRODUCTION: Caregivers play an important role in Parkinson's disease (PD) treatment, especially as the disease progresses. As the symptom profile and needs of people with PD (PwP) differ across ethnoracial groups, whether caregiving needs also differ for different ethnoracial groups should be investigated. METHODS: Data were obtained from the Parkinson's Foundation funded Parkinson's Outcomes Project for PwP identifying as Hispanic (n = 495), non-Hispanic Asian (n = 170), non-Hispanic Black (n = 162), or non-Hispanic White (n = 7687). Cross-sectional and longitudinal total Multidimensional Caregiver Strain Index (MCSI) and domain-specific scores for caregiving burden were compared across the ethnoracial groups. Effect of demographics and clinical variables, interaction of these variables with ethnoracial groups for caregiver burden was assessed. RESULTS: Care partners of PwP identifying as non-Hispanic Asian experienced the most burden. PwP identifying as non-Hispanic White were oldest, yet their care partners experienced the least burden. Care partners of PwP identifying as non-Hispanic Asian experienced more burden in physical and social domains, care partners of PwP identifying as Hispanic experienced more burden in financial and elder demanding/manipulative domains. Over time, burden increased similarly across the ethnoracial groups. Effect of frequency of falls, hospital admission, neuropsychiatric disorder and social support on burden over time differed across the groups. CONCLUSION: PwP from different ethnoracial groups can experience different levels of caregiving burden. Predictors for caregiving burden, such as social support and falls can have different impacts based on ethnicity and race. Caregiver needs should also be assessed and culturally competent support should be provided to benefit all affected by PD.
