Intensity of care and the health status of caregivers to elderly rural South Africans

ObjectivesInformal caregivers play an indispensable role in and are often the sole source of care for older adults in low and middle-income settings worldwide. Intensive informal care predicts mortality and morbidity among caregivers in higher-income settings. However, there is limited evidence from poorer settings, including Africa countries, where caregiving is shared widely, including across generations. We therefore investigated caregivers health status in rural South Africa. MethodsWe conducted quantitative interviews with all household members and all non-household caregivers aged [≥]12 (n=1012) of 106 older adults in rural Mpumalanga, South Africa. We used multivariable regression with care-recipient random intercepts to assess the relationships between four caregiving characteristics and both self-reported chronic conditions and self-reported health status, considering how caregiver age moderated each association. ResultsOver half of all caregivers reported at least one chronic health condition, despite half being aged under 40. Caregivers self-reporting the worst health status provided high hours of care. However, caregivers health status was not significantly associated with weekly care quantity or history of caring. Those aged [≥]40 who reported being a main caregiver had 52% increased odds of reporting poorer health compared to other same-aged carers (95% confidence interval: 0.99, 2.35), while having more chronic conditions was associated with being expected to act as a sole caregiver more often among caregivers aged [≤]39. DiscussionGreater caring responsibilities for older adults were not consistently associated with caregivers health in a setting where poor health is common, and caregiving is spread widely. Longitudinal data is necessary to unpack possible explanations of these findings, and to determine whether intensive caregiving speeds downward health trajectories for carers.
