Contributors to Gender Disparities in Parkinson's Disease Caregiving.

BackgroundWomen with Parkinson's disease (PD) are less likely to have a caregiver.ObjectiveTo determine factors contributing to gender disparities in PD caregiving.MethodsWe conducted a cross-sectional survey of people with PD and caregivers participating in the Parkinson's Foundation Parkinson's Outcomes Project and compared patient and caregiver characteristics by gender.ResultsAmong PD patients, 20.7% of 1663 women and 14.2% of 3005 men had no caregiver ( < 0.001). Women without caregivers were older (69.1 vs 66.3, < 0.001), less likely to be married (30.4% vs 54.7%, < 0.001), and more likely to be taking an antidepressant (41.8% vs 30.9%, = 0.002) than men. Using stepwise logistic regression models, gender differences in access to caregiving were explained by marital status. Among caregivers, women reported more strain ( < 0.001) and had less time for other family members ( < 0.001).ConclusionFewer women with PD have caregivers because they are less likely to have a spouse.
