Arline Geronimus, a professor at the University of Michigan School of Public Health, coined the term "weathering" for stress-induced wear and tear on the body. Weathering "causes a lot of different health vulnerabilities and increases susceptibility to infection," she said, "but also early onset of chronic diseases, in particular, hypertension and diabetes" — conditions that disproportionately affect blacks at much younger ages than whites.
"It's chronic stress that just happens all the time — there is never a period where there's rest from it. It's everywhere; it's in the air; it's just affecting everything," said Fleda Mask Jackson, an Atlanta researcher who focuses on birth outcomes for middle-class black women.
It's a type of stress for which education and class provide no protection. "When you interview these doctors and lawyers and business executives, when you interview African-American college graduates, it's not like their lives have been a walk in the park," said Michael Lu, a longtime disparities researcher and former head of the Maternal and Child Health Bureau of the Health Resources and Services Administration, the main federal agency funding programs for mothers and infants. "It's the experience of having to work harder than anybody else just to get equal pay and equal respect. It's being followed around when you're shopping at a nice store, or being stopped by the police when you're driving in a nice neighborhood." Chronic stress "puts the body into overdrive," Lu said. "It's the same idea as if you keep gunning the engine, that sooner or later you're going to wear out the engine."
