The health of older caregivers in Spain: a matter of age or a matter of care?

Abstract Introduction Informal care is crucial in Spain’s care system, with a rising number of caregivers aged 75 or older, yet studies on its health effects are lacking. This study aims to determine the differential impact of age and care-related variables on the health of older caregivers. Materials and methods This is a cross-sectional, national study with a sample of 3,870 informal caregivers from the Spanish 2020 Disability, Personal Autonomy and Dependency Survey. We performed a logistic regression where self-reported deterioration in caregiver health due to caregiving was the dependent variable and age (<75 vs. ≥ 75) was the independent variable. Caregivers’ sex, educational level (primary and lower or secondary and higher), income (<1,150 euros per month vs. ≥ 1,150), severe functional limitation of caregivers and care-receptors (yes or no), duration of care (< 8 years vs. ≥ 8 years), and daily hours of care were used as covariates. Results One in 6 caregivers was 75 or older (16,1%). Caregivers’ mean age was 58.4, and care-receptors’ 66.6 years. Women represented 63.0% of caregivers, and 42.8% of care-receptors. Up to 4.6% of caregivers had a severe limitation, and 43.7% of caregivers reported deterioration of their health due to caregiving. A greater perception of deterioration in caregiver health due to caregiving was associated with being 75 years or older (β = 0.34, p = 0.009). Covariates associated with caregivers’ health deterioration were being a woman (β = 0.77, p < 0.001), presence of severe limitation of care receptors (β = 0.58, p < 0.001), and increased daily hours of care (β = 0.01, p = 0.013). Caregivers’ severe limitation, level of education, income and years of care did not show a significant association with perception of health deterioration. Discussion Caregivers older than 75 years in Spain experience a key deterioration in their health associated with caregiving. This vulnerable population must be prioritized in health and social policies. Key messages • One out of 6 caregivers in Spain is aged 75 years or older. Caregiving impacts greatly in their health status. • Older caregivers is a vulnerable population that must be a priority for health and social services.
