An estimated 44 million adults in the United States provide unpaid care to another adult.
A 2004 study commissioned by the AARP and other organizations estimated that caregiving is more stressful on women, who make up more than six in 10 caregivers: 40 percent said caregiving stressed them at high levels, compared to just 26 percent of men.
“Adult daughters place greater emphasis on their relationships with their parents, and when those relationships go awry, it takes a worse toll on the adult daughters than the adult sons,” said review author Marina Bastawrous, a graduate student at the University of Toronto.
