New diabetes cases are down in the U.S. for the first time in decades, according to a new CDC report.
There were 1.4 million new cases of diabetes in 2014, a drop from 1.7 million in 2008.
It's the first time in a quarter century there's been a significant decline, the CDC reported. Over that period, the number of adults between 18 and 79 with newly diagnosed diabetes cases more than tripled -- jumping from 493,000 to more than 1.4 million new cases a year. About 21.9 million Americans now live with the disease.
A study last year estimated that nearly 10 percent of U.S. adults have type 2 diabetes, and other research finds more than a third of adults have prediabetes, a high blood sugar condition that may lead to diabetes.
But this latest CDC data shows a small but promising reversal. "It seems pretty clear that incidence rates have now actually started to drop," Edward Gregg, a diabetes researcher with the CDC, told The New York Times.
"Initially it was a little surprising because I had become so used to seeing increases everywhere we looked," Gregg said.
Whether prevention efforts are finally bearing fruit, or if the disease has peaked, is unclear, the Times reports.
