A new report from the Centers for Disease Control and Prevention suggests the rapid rise in US diabetes rates may be flattening out, possibly due to a similar slowing in increases in obesity. Published in JAMA, the report looked at data on more than 660,000 adults from the National Health Interview Survey. Although incidence of new diagnoses of diabetes had shot up from 3.2 per 1,000 people in 1990 to 8.8 in 2008, that rate actually dropped to 7.1 in 2012. Overall prevalence of diabetes, which rose sharply from 3.5 per 100 Americans to 7.9 from 1990 to 2008, increased only slightly to 8.3 by 2012.
The rate of new cases continued to rise, however, among blacks and Hispanics, and diabetes prevalence grew among people with a high school education or less. Researchers warned, This threatens to exacerbate racial/ethnic and socioeconomic disparities in diabetes.
