Harvard and University of Washington epidemiologists and colleagues have out in PLoS Medicine a few stunning maps to back their discovery of a striking pattern of declining life expectancies among American, with women affected most profoundly. It is seen, reports the Washington Post's David Brown, most clearly in rural and low-income areas, with heaviest concentration in the Deep South, Appalachia, and lower Midwest (plus one county in Maine). Data extend for such fine analysis extend only to 2000.
The patterns could be, Brown adds, "the leading edge of the obesity epidemic" combined with diabetes, lung cancer and emphysema from smoking, and kidney failure. Nothing like this, he adds, has been seen for nearly 100 years. Men, for reasons unclear except perhaps they've been smoking more and longer, don't show much shift. Plus, their longevity still, in aggregate, trails that of women.
The post's account is hardly the only one, as the story is boosted by press releases and full, open access to the journal report (see Grist).
