The rate of new cases of diabetes fell by about a fifth from 2008 to 2014, according to researchers at the Centers for Disease Control and Prevention, the first sustained decline in about 25 years. New data for 2014 released on Tuesday serves as confirmation that the decline is real, officials said. There were 1.4 million new cases of diabetes in 2014, down from 1.7 million in 2008.
Experts say they do not know whether efforts to prevent diabetes have finally started to work, or if the disease has simply peaked in the population. But they say the shift tracks with the gradual progress that has been reported recently in the health of Americans.
