Open access via Public Library of Science, PLoS Medicine, April 2008, Vol. 5, No. 4, e66 doi:10.1371/journal.pmed.0050066.
- "There was a steady increase in mortality inequality across the US counties between 1983 and 1999, resulting from stagnation or increase in mortality among the worst-off segment of the population. Female mortality increased in a large number of counties, primarily because of chronic diseases related to smoking, overweight and obesity, and high blood pressure."
