Diabetes Diagnoses on the Decline
The rate of new diabetes cases is dropping - for the first time in 20 years, the Centers for Disease Control and Prevention reported recently.
New diagnoses among American adults are down about one-fifth from 2009 to 2014, new data reveals.
According to first study author Andy Menke, most adults don't know there's a problem until they get a diagnosis.
"Among everyone with diabetes in the U.S., about one in three were unaware that they had the condition," Menke said in an interview with NBC News.
While the study found a decrease in new diabetes diagnoses, the number of American adults who have the condition has doubled in the last two decades.
Not as much data for Asian Americans
The CDC's report found that diabetes diagnoses were on the decline among white, black and Hispanic adults, but it did not provide significant information about Asian Americans.
"There's not as much data there," said Dr. Edward Gregg, from the CDC's Division of Diabetes Translation.
The National Institutes of Health and the CDC have previously reported that Asian Americans have the highest proportion of undiagnosed diabetes.
While weight gain is generally the most common risk factor for developing type 2 diabetes, this isn't the case for many Asian Americans, the study authors said.
A study published last year by the American Diabetes Association suggested that Asian Americans be tested for diabetes if they have a BMI of 23 or higher.
"Unfortunately, these studies did not have adequate statistical power to accurately estimate cases of diabetes among Asian Americans in previous decades, so it's not possible to look at long-term trends in this population," Menke said.
