ANN ARBOR, Mich.---Working mothers are two-and-a-half times as likely as working fathers to interrupt their sleep to take care of others.
That is the finding of a University of Michigan study providing the first known nationally representative data documenting substantial gender differences in getting up at night, mainly with babies and small children.
And women are not only more likely to get up at night to care for others, their sleep interruptions last longer---an average of 44 minutes for women, compared to about 30 minutes for men.
"Interrupted sleep is a burden borne disproportionately by women," said sociologist Sarah Burgard, a researcher at the U-M Institute for Social Research (ISR). "And this burden may not only affect the health and well-being of women, but also contribute to continuing gender inequality in earnings and career advancement."
The study, forthcoming in the peer-reviewed journal Social Forces, was funded by the National Institute of Child Health and Human Development, the National Institute on Aging, and the Sloan Foundation.
For the study, Burgard analyzed time-diary data from approximately 20,000 working parents from 2003 to 2007, drawn from the U.S. Census Bureau's American Time Use Survey.
The gender gap in sleep interruptions was greatest during the prime childbearing and child-rearing years of the twenties and thirties, she found.
Among dual-career couples with a child under the age of one, 32 percent of women reported sleep interruptions to take care of the baby, compared with just 11 percent of men. The proportion reporting interrupted sleep declined with the age of the child, with 10 percent of working mothers and 2 percent of working fathers with children ages 1 to 2 reporting sleep interruptions, and just 3 percent of working mothers and 1 percent of working fathers with children ages 3 to 5.
"What is really surprising," Burgard said, "is that ge
