BackgroundThe caregiving scholarship widely acknowledges informal caregivers’ contributions to maintaining older adults’ health and well-being. However, informal caregivers encounter economic, physical, social, financial and psychological challenges when caring for older adults. The caregiving literature has shown variations in caregiving intensity and motivation between rural and urban informal caregivers of older adults. This situation is likely to result in rural-urban disparities in caregiver burden. However, the literature on predictors of caregiver burden is more focused on demographic, socio-economic, caregiving and health-related factors with very little attention to geographical dynamics. For this reason, the effects of demographic, socio-economic, caregiving, and health-related factors on the variations in caregiver burden between rural and urban informal caregivers of older adults are yet to be known in the sub-Saharan African context, including Ghana. Notably, the impact of geographical location on caregiver burden is mainly missing in the informal caregiving literature in Ghana. Situated within the stress process model, we determine the association between geographical location and caregiver burden among informal caregivers of older adults in Ghana.MethodsThis study employed data from a large cross-sectional survey on informal caregiving, health, and healthcare among caregivers of older adults aged 50 years or above (N = 1,853) in Ghana. We selected the World Health Organization Impact of Caregiving Scale to measure caregiver burden. Generalized multivariable linear regression models were employed to determine the association between geographical location and caregiver burden among informal caregivers of older adults. We reported beta values and standard errors with significance levels of 0.05 or less.ResultsThe results showed that rural informal caregivers of older adults significantly have a decreased caregiver burden compared to urban informal caregivers (β = -1.64; SE = 0.41). Also, participants across all the self-rated health categories (poor/very poor: β = 12.63; SE = 1.65; fair: β = 9.56; SE = 1.07; good: β = 11.00; SE = 0.61, very good: β = 7.03; SE = 0.49) have a significantly increased caregiver burden for the full sample and for both rural (poor/very poor: β = 13.88; SE = 2.4; fair: β = 6.11; SE = 1.62; good: β = 9.97; SE = 0.96, very good: β = 6.06; SE = 0.71) and urban (poor/very poor: β = 11.86; SE = 2.25; fair: β = 12.33; SE = 1.42; good: β = 11.80; SE = 0.79, very good: β = 7.90; SE = 0.67) participants. This study further revealed that participants with no financial support needs reported a decreased caregiver burden compared to those with financial support needs for the full sample (β = -2.92, p-value < 0.01) and for both rural (β = -3.20; p-value < 0.01) and urban (β =-2.70; p-value < 0.01) participants.ConclusionThe findings from this study underscore geographical location differences in caregiver burden among informal caregivers of older adults in Ghana. Given these findings, the need to consider geographical location variations in providing welfare and health support programs to lessen caregiver burden among informal caregivers of older adults is welcomed. In line with the stress process model, such welfare and health programs should consider background, context, and stressor factors that contribute to variations in caregiver burden between rural and urban informal caregivers of older adults in Ghana and other sub-Saharan African countries.
