In the past 10 years, the rate of new diabetes cases has almost doubled in the U.S. The South had the highest levels. All this was stated in the government’s state-by-state review of new diagnoses.
West Virginia had the highest rate, where 13 in 1,000 adults were diagnosed with the disease. Minnesota, a northern state, had the lowest, where there was 5 in 1,000 cases.
Type 2 diabetes, the form that is linked to obesity, accounted for 90 percent of the cases. The findings reflect geographic trends that occur with obesity and physical inactivity, which are also tied to heart disease. The southern states ranked the worst in these cases as well.
The study was done by the U.S. Centers for Disease Control and Prevention and covered most states. Previous studies have given state-specific estimates of diabetes cases, but this is the only one that has charted where the new cases are being diagnosed.
Diagnosed diabetes cases was the only thing asked about in the report. Considering an estimated 1 in 4 diabetics have not yet been diagnosed, the problem is most likely underestimated.
More than 260,000 adults were involved in the study which used a random-digit-dialed survey. The participants were asked if they were diagnosed with having diabetes and when the diagnosis was given.
The yearly rate of new diabetes cases climbed from nearly 5 per 1,000 in the mid-1990s to 9 per 1,000 in the mid-2000s. This data was gathered from 33 states for which CDC had complete data for both periods of time.
The researchers were able to get data for 40 states for the years 2005-07. South Carolina, West Virginia, Alabama, Georgia, Texas and Tennessee had the highest rates, all at 11 per 1,000 or more.
