Abstract only
Background:
Informal home care is the most prevalent type of post-acute care (PAC) in Mexican American (MA) stroke survivors, but data on the impact on caregivers is not available. The objective was to investigate strain, positive aspects of caregiving, familial obligations/support, and depression in stroke caregivers and ethnic differences in a population-based study.
Methods:
Data are from Brain Attack Surveillance in Corpus Christi PAC Study. Community-dwelling stroke survivors and their caregivers were recruited (n=307). Caregiver eligibility included: 1) residence in study county, 2) not cognitively impaired, 3) not providing care pre-stroke. Caregiver interviews at ~90 days included sociodemographics, dyad characteristics, Modified Caregiver Strain Index (MCSI range 0-26, higher more), PAC scale by Tarlow et al (range 5-45, higher more), familial obligations/support scales by Sabogal et al (range 1-5, higher greater), and PHQ-8 (range 0-30, higher worse). Patient data were from interviews and medical records. Propensity score (PS) methods were used to balance caregiver and patient factors among MA and non-Hispanic white (NHW) caregivers by fitting a model with ethnicity of caregiver as the outcome and predictors being caregiver sociodemographics, patient-caregiver dyad characteristics, and patient sociodemographics and disability. PS were then included as a covariate in regression models considering the association between ethnicity and outcomes.
Results:
MA caregivers were younger, more likely female, and more likely a child than NHWs. Median MCSI, PAC scale, PHQ-8 were 11 (IQR:6-17), 36 (IQR:30-40), and 11 (IQR:9-15) in MAs and 13.5 (IQR:9-18.3), 30 (IQR:25-36.3) and 13 (IQR:10-16) in NHWS. MA ethnicity was associated with less caregiver strain (β=-2.22, 95% CI:-4.19, -0.26) and depression (β=-2.05, 95% CI:-3.48, -0.63) and more positive aspects of caregiving (β=2.96, 95% CI:0.91, 5.01), but not associated with familial obligations/support.
Conclusions:
Informal stroke caregivers report moderate levels of strain and depressive symptoms, with NHW caregivers reporting higher levels. MA caregivers report greater positive aspects of caregiving suggesting a possible intervention target to improve outcomes in MAs.
