Diabetes prevalence rates jumped dramatically across the nation between 1995 and 2010, researchers at the U.S. Centers for Disease Control reported in Friday’s edition of the Morbidity and Mortality Weekly Report.
Using data from the Behavioral Risk Factor Surveillance System, an annual phone survey of adults 18 and older, the investigators found that overall, the median prevalence of diagnosed diabetes went up from 4.5% in 1995 to 8.2% in 2010.
Prevalence increased in all states, the District of Columbia and Puerto Rico, with the median up from 4.5% to 8.2%. Diabetes rates were highest in the South and in Appalachia, where Alabama, Mississippi, South Carolina, Tennessee, Texas and West Virginia all had 2010 rates above 10%. Rates also exceeded 10% in Puerto Rico.
The states with the lowest prevalence of diabetes, between 6.0% and 6.9%, were Alaska, Colorado, Connecticut, Iowa, Minnesota, Montana, North Dakota, Oregon, South Dakota, Wisconsin, Vermont and Wyoming. In California, 8.6% of the people had the disease -- a 38% increase over 1995.
