Life expectancy for the least-educated Americans has shrunk by four years since 1990, a reminder that social inequality is not just a matter of having fewer things than those who are better off than you.
Exactly why the decline occurred isn’t understood, but a rise in prescription drug overdoses among white youths, higher rates of tobacco use, growing obesity and a lack of health insurance were offered by researchers as possible explanations.
The steepest declines were for white women without a high school diploma, who lost five years of life between 1990 and 2008, said S. Jay Olshansky, a public health professor at the University of Illinois at Chicago and the lead investigator on the study, published last month in Health Affairs. By 2008, life expectancy for black women without a high school diploma had surpassed that of white women of the same education level, the study found.
White men lacking a high school diploma lost three years of life. Life expectancy for both blacks and Hispanics of the same education level rose, the data showed. But blacks over all do not live as long as whites, while Hispanics live longer than both whites and blacks.
“We’re used to looking at groups and complaining that their mortality rates haven’t improved fast enough, but to actually go backward is deeply troubling,” said John G. Haaga, head of the Population and Social Processes Branch of the National Institute on Aging, who was not involved in the new study.
