Diabetes rates rise dramatically, CDC reports
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.
Two comments before people start talking about high-fructose corn syrup and the like:
1. Criteria for diagnosis also changed in the same time frame.
2. The population aged in the same time frame.
I'd like to see a comparison taking those two factors into account. Indeed, those factors SHOULD BE taken into account in any comparison; otherwise, reports like this are just spreading misinformation.

During 1995–2010, the age-adjusted prevalence of diagnosed diabetes among U.S. adults increased in all geographic areas, with the median prevalence for all states, DC, and Puerto Rico increasing from 4.5% to 8.2% (Table). In 1995, age-adjusted prevalence was ≥6% in only three states, DC, and Puerto Rico, but, by 2010, it was ≥6% in all areas (Table, Figure 1). In 2010, median age-adjusted prevalence was highest among states in the South (9.8%) versus states in the Midwest (7.5%), Northeast (7.3%), and West (7.3%). In 2010, age-adjusted prevalence was highest (≥10.0%) in Alabama, Mississippi, Puerto Rico, South Carolina, Tennessee, Texas, and West Virginia, and lowest (6.0%–6.9%) in 12 states: Alaska, Colorado, Connecticut, Iowa, Minnesota, Montana, North Dakota, Oregon, South Dakota, Wisconsin, Vermont, and Wyoming.
During 1995–2010, the relative increase in age-adjusted prevalence of diabetes ranged from 8.5% in Puerto Rico to 226.7% in Oklahoma, with an overall median increase of 82.2%. The age-adjusted prevalence increased by ≥50% in 42 states and by ≥100% in 18 states. States in the South had the largest relative increase in prevalence, with the age-adjusted median increasing >100% (Table, Figure 2). The next largest increase was seen in the West, where the median increased 82.5%, followed by a 66.7% increase in the Midwest and a 62.2% increase in the Northeast.
This increase is likely the result of improved survival of persons with diabetes and increasing diabetes incidence. Nationally representative data (4) suggest that mortality among U.S. adults with diabetes declined substantially between 1997 and 2006, and at a faster rate than among adults without diabetes. This trend is paralleled by improvements in the health of persons with diabetes, including lower levels of risk factors for complications (e.g., hyperglycemia and uncontrolled blood pressure), decreased rates of complications associated with increased risk of death, and improvements in quality of care and medical treatments (5–7).
The major driver of the increase in diabetes prevalence is the increase in the incidence of diabetes in the United States since 1990 (2,3). Increasing incidence might be the result of many factors, including changes in diagnostic criteria, enhanced detection of undiagnosed diabetes, demographic changes in the U.S. population (e.g., aging of the population and growth of minority populations who are at greater risk for diabetes), and an increase in the prevalence of risk factors for the development of diabetes (e.g., obesity and sedentary lifestyle). Although the contribution of each factor to increasing diabetes incidence cannot be discerned, the increase in diabetes prevalence coincides with the increase in obesity prevalence across the United States (3,8,9).§

3. it would be pretty easy to determine how much was due to changes in diagnostic
criteria. sample medical facilities and see what percent of diagnosed diabetics would be so diagnosed under older criteria and extrapolate to the general population.
easy to do the research related to aging of the population too.
nobody's doing it so i guess they're not interested.
