Life expectancy declining for some American women
Today, life expectancy in the United States is 81.1 years for women and 76.3 years for men, according to the Centers for Disease Control and Prevention. These numbers are up significantly from 1970, showing a nearly 10-year increase among women and a nine- year increase for men. This can likey be attributed to better medical technology, both in diagnostics and treatment.
But researchers are the University of Wisconsin were surprised to find that between 1992 and 2006, in 42.8 percent of the counties in America showed, the mortality rates for women 75 years and younger actually worsened. The compared to worse mortality rates in only 3.4 percent of U.S. counties for men during the same period. This decline in life expectancy was most apparent in rural areas of the South and West.
The study did not definitively conclude what was causing the lowered life spans, but the researchers speculated that socioeconomic and behavioral factors, including higher rates of smoking and lower education levels, may be a factor.
