Informal and unpaid care is an integral feature of the U.S. health care sys
tem for the nation's sick, disabled, frail, and terminally ill. Much of wha
t we know about caregiving is based on interviews with caregivers and, in s
ome cases, care recipients. Prior studies have either not been based on a n
ationally representative sample or have collected very little information a
bout non-caregivers. This study, using the Commonwealth Fund 1998 Survey of
Women's Health, uses a nationally representative sample of caregivers and
non-caregivers to examine the health impact of providing informal and unpai
d care, focusing primarily on women. Our findings indicate that caregivers
experience double jeopardy. They are significantly more likely to be in poo
r health and to have experienced problems getting needed care. These findin
gs suggest that it is time to explore alternative or complements to informa
l caregiving. They underscore the need to find more equitable ways to share
caregiving costs and risk, and provide support to assist those who current
ly provide care.
