ATLANTA (AP) - A new analysis by the Centers for Disease Control and Prevention says as many as 1 in 3 adults in the United States could have diabetes by 2050.

That would be a sharp rise from the current figure of one in 10.

The report predicts that the number of new diabetes cases each year will increase from 8 per 1,000 people in 2008, to 15 per 1,000 in 2050.

Factors cited by the CDC are an aging population more likely to develop type 2 diabetes, increases in minority groups that are at high risk, and people with diabetes living longer.

Diabetes was the seventh leading cause of death in 2007 and the CDC says it's the leading cause of new cases of blindness among adults under age 75. It's also the leading cause of kidney failure, and non-injury leg and foot amputations among adults.

Proper diet and physical activity can reduce the risk of diabetes, and help to control the condition in people with diabetes.

The study is in the journal Population Health Metrics.
