A new report has shown that half of the U.S. adults are suffering from diabetes or high blood sugar, NBC news reports.

Andy Menke of global health research company Social & Scientific Systems, Catherine Cowie of the National Institute of Diabetes and Digestive and Kidney Diseases and others based their report on the annual national survey data of 5,000 people.

The report showed that in 2012, about 12 percent to 14 percent of adults had been diagnosed with diabetes.

The study also included Asian Americans and found that nearly twenty percent of Asian-Americans had diabetes and half of them were undiagnosed. Among other races, nearly 22 percent of blacks, 20 percent of Asians and 22.6 percent of Hispanics had diabetes.

"The proportion of diabetes that's undiagnosed is as high as 50 percent in Asian-Americans and the Hispanic population compared to about a third in whites and it blacks," Cowie said.

The report noted that there was a dramatic rise in diabetes between 1990 and 2008, with the levels stabilizing after that.

"Diabetes prevalence significantly increased over time in every age group, in both sexes, in every racial/ethnic group, by all education levels, and in all poverty income (groups)," the team wrote in the Journal of the American Medical Association.

Last year, a study by the Centers for Disease Control and Prevention study reported that 29 million Americans have diabetes and another 86 million have pre-diabetes.
