The authors of the BMJ essay note that the roughly 15-year run-up in drug deaths and suicides has not been seen in black Americans.
While the racial gap in health is narrowing, African Americans' rates of premature death have always been starkly higher than those among whites, Woolf said. And it may be that the uptick in "deaths of despair" seen in whites will eventually be detected among blacks as well, he adds.
But Woolf says it's also possible that black Americans have some "resilience factor" that white Americans do not. Perhaps, he said, African-Americans' response to the discrimination, structural disadvantages and health inequities they've long endured has buffered them from following whites down their path of self-destruction.
At the same time, the despair of whites is "unclear, complex, and not explained by opioids alone," Woolf and Aron wrote. In once-thriving communities outside the nation's metropolitan areas, industries have collapsed. As steel mills and coal mines have closed, timber production has gone bust, and automation has left rural communities behind, their economies and their residents' health have suffered.
The result is a national phenomenon that has been unfolding for at least three decades. Relative to life expectancy in other affluent, industrialized countries, Americans' once-commanding lead in longevity began slipping in the early 1980s. By 1998, U.S. life expectancy had fallen below the average for industrialized countries. It is now 1.5 years behind that benchmark.
"It's really sad that a baby born today will likely live less long than one born even a year ago. It's not the direction you'd expect the richest country on Earth to be going," Woolf said.
But economic collapse might be too easy an explanation for rural white communities' epidemic of despair, said Woolf, who has studied the urban-rural health divide across the country. More important might be the fraying of communities' social fabric that followed.
"Poverty rates don't capture the frustration and hopelessness people experience when they can't get ahead or can't give their kids a better life," Woolf said. When the social fabric of a community is frayed, its residents may be more inclined to salve their woes in self-destructive behaviors, he added.
A look at broader U.S. trends and policies may also shed light on the roots of some Americans' despair, Woolf and Aron wrote. During the three decades during which U.S. life expectancy has slid, the nation's educational performance weakened. Its social divides (including income inequality) widened. Its middle-class incomes stagnated. And its poverty rates exceeded those of most rich countries.
"These are all factors we know are important to health," Woolf said.
If policymakers want to reverse the trend of shortening U.S. lifespans, "they would promote education, boost support for children and families, increase wages and economic opportunity for the working class, invest in distressed communities, and strengthen healthcare and behavioral health systems," Woolf and Aron wrote.
At the end of the day, Woolf said, "it's probably not a good time to make policy choices that don't invest in helping these people. A policy agenda that's focused on improving value for shareholders is not really going to bring relief to these families and communities."
