More Education Tied to Longer Life
New research has found that, despite advances in health care, Americans who have the least education also have shorter lives.
“The most highly educated white men live about 14 years longer than the least educated black men,” reported S. Jay Olshansky, Ph.D., a professor of epidemiology at the University of Illinois at Chicago School of Public Health and lead author of the study. “The least educated black women live about 10 years less than the most educated white women.”
The research examined life expectancy by race, sex and education, as well as examined trends in disparities from 1990 through 2008. The study was published in the journal Health Affairs.
The study found that while almost all “longevity boats” have risen over the past couple of decades, a few subgroups have had a drop in life expectancy, according to Olshansky.
“It’s as if Americans with the least education are living in a time warp,” he said, noting that their life expectancies show that the “the least educated black men are living in 1954, black women in 1962, white women in 1964, and white men in 1972.”
One surprising finding, according to Olshansky, is that white women with less than 12 years of education can expect to live five years less than their counterparts in 1990 — a decline from age 78 to 73.
Black women with less than 12 years education can expect to live to age 74, up from age 73 two decades ago.
The researchers speculate that the least educated black women are experiencing high levels of obesity, which has a delayed effect on negative health consequences, while white women may be adopting more immediately lethal behaviors such as smoking, alcohol consumption and drug use.
Olshansky says there are “essentially two Americas.” One subgroup of the population is highly educated, doing well, and experiencing a dramatic increase in life expectancy, he said.
Another subgroup is less educated, doing very poorly, and experiencing a drop or only modest increases in life expectancy.
The researchers conclude that education and socioeconomic status are extremely important variables that influence variations in longevity. They suggest that one of the most important ways to address these large disparities is through education.
“We must find a way to bring these subgroups of the population back into the present,” Olshansky said.
