Physical and mental health of Chinese grandparents caring for grandchildren and great-grandparents

Abstract

The increasing worldwide prevalence and intensity of grandparenting has attracted an attention to its health implications for caregivers against the backdrop of population aging. Thanks to prolonged life expectancy and reduced infant mortality, extended families that comprise four generations, co-residential or not, are no longer rare in China. The current study examines health consequences when Chinese grandparents provide care to not only grandchildren but also their own elderly parents or parents-in-law (i.e., great-grandparents). Drawing on data from the 2011–2013 China Health and Retirement Longitudinal Study (CHARLS), mental health was captured by levels of life satisfaction and depressive symptoms, and physical health was measured by levels of high sensitivity C-reactive protein (CRP), hypertension, high-risk pulse rate, and diabetes. Overall grandparents who cared for grandchildren only had better mental and physical health, compared with non-caregivers. There was some evidence that the ‘sandwich’ grandparents who cared for both grandchildren and great-grandparents reported greater life satisfaction, fewer depressive symptoms, and reduced hypertension compared with non-caregivers. The health advantage of caregiving was most pronounced in urban grandfathers whose caregiving conformed to the norm of filial piety and who did so most likely to seek emotional reward instead of an intergenerational time-for-money exchange. In contrast, rural grandmothers were the most vulnerable group and their health disadvantage seemed to arise from caring for great-grandparents. These findings highlight the importance of rural-urban context and gender role in studying the health effects of intergenerational caregiving on Chinese grandparents.
