The purpose of this article is to investigate the relationship between spousal care-giving and declines in functioning and self-rated health among older care-givers. The authors used data from the 2000 and 2002 waves of the United States Health and Retirement Study, a biennial longitudinal survey of a nationally representative cohort of adults aged 50 or more years. Two outcomes were examined, declines in functioning and declines in self-rated health.
