A woman in Collier County, Florida, has 12 years on a woman in Holmes, in the Mississippi Delta region of the southern state, said researchers at the Institute for Health Metrics and Evaluation at the University of Washington in Seattle. The study examined life expectancy in 3,147 U.S. counties through 2007.
Tobacco use, obesity and high blood pressure have dropped life expectancy in Appalachia, the Deep South and northern Texas, said Christopher Murray, the institute director and a report author. He called for more investment in public-health programs and increased emphasis on primary care so doctors can catch and control high blood pressure and cholesterol levels.
