Life Expectancy for American Females Has Mysteriously Shortened
Multiple studies have revealed that the life expectancy of women in the United States has declined in recent decades, leaving experts searching for the cause.
Research published in March by University of Wisconsin researchers David Kindig and Erika Cheng found that female mortality rates went up in nearly half of U.S. counties between 1992 and 2006. For men, only 3% of counties witnessed increases in male mortality over the same period.
“I was shocked, actually,” Kindig told The Atlantic. “So we went back and did the numbers again, and it came back the same. It’s overwhelming.”
A few months later, a report by University of Washington researcher Chris Murray and four co-authors found that female life expectancy had either remained the same or declined in 45% of counties from 1985 to 2010.
“Taken together, the two studies underscore a disturbing trend: While advancements in medicine and technology have prolonged U.S. life expectancy and decreased premature deaths overall, women in parts of the country have been left behind, and in some cases, they are dying younger than they were a generation before,” Grace Wyler wrote for The Atlantic.
“The worst part is no one knows why,” she added.
The Kindig study indicated a correlation between mortality rates and geography, with rising female death rates occurring throughout parts of the South and in the Great Plains, while the Northeast and the Southwest did not experience this problem.
A third study, published last year, showed a link between education and health in concluding that life expectancy for white female high-school dropouts had gone down significantly over the past 18 years.
Wyler wrote that these women “are now expected to die five years earlier than the generation before them—a radical decline that is virtually unheard of in the world of modern medicine.”
Jay Olshansky, lead author of the 2012 study, agreed, telling Wyler: “It’s unprecedented in American history to see a drop in life expectancy of such magnitude over such a short time period.”
“I don't know why it happened so rapidly among this subgroup. Something is different for the lives of poor people today that is worse than it was before,” Olshansky said.
