Risk of Stroke Twice as High in Diabetics

Diabetes is a complicated set of diseases. While many of us have heard terms like insulin and glucose levels associated with it, few are aware that diabetes is a deadly disease. It was the 7th leading cause of death in the U.S in 2010.

Here are some astounding numbers from the 2014 National Diabetes Statistics Report:

Overall Numbers, Diabetes and Prediabetes

Prevalence: In 2012, 29.1 million Americans, or 9.3% of the population, had diabetes. In 2010 the figures were 25.8 million and 8.3%. The prevalence rate for adults age 20 and older in 2012 was 12.3%, compared to 11.3% in 2010.

Undiagnosed: Of the 29.1 million, 21.0 million were diagnosed, and 8.1 million were undiagnosed. In 2010 the figures were 18.8 million and 7.0 million.

Prevalence in Seniors: The percentage of Americans age 65 and older remains high, at 25.9%, or 11.8 million seniors (diagnosed and undiagnosed).

Incidence: The incidence of diabetes in 2012 was 1.7 million new diagnoses/year; in 2010 it was 1.9 million.

Prediabetes: In 2012, 86 million Americans age 20 and older had prediabetes; this is up from 79 million in 2010. The percentage is up slightly, from 35% in 2010 to 37% in 2012—and is now at 51% among those age 65 and older.

Diabetes in Youth

About 208,000 Americans under age 20 are estimated to have diagnosed diabetes, approximately 0.25% of that population (the figure is essentially unchanged from 2010, when it was estimated at 215,000/0.26%).

In 2008—2009, the annual incidence of diagnosed diabetes in youth was estimated at 18,436 with type 1 diabetes, 5,089 with type 2 diabetes. This represents a modest increase in the percentage of youth being diagnosed with type 2, from 19% in 2002—2005, to 22% in 2008—2009.

Diabetes by Race/Ethnicity

The new Statistics Report contains greater detail on diabetes in minority populations than has been available before, particularly for Asian Americans. The rates of diagnosed diabetes by race/ethnic background are:

•    Non-Hispanic whites    7.6%
•    Asian Americans    9.0%
•    Hispanics    12.8%
•    Non-Hispanic blacks    13.2%
•    American Indians/Alaskan Natives    15.9%
•    The breakdown among Asian Americans: 4.4% for Chinese, 11.3% for Filipinos, 13.0% for Asian Indians, and 8.8% for other Asian Americans.

Other Complications/Co-morbid Conditions

According to the 2014 National Diabetics Statistics Report:

•    Hypoglycemia: In 2011, about 282,000 emergency room visits for adults aged 18 years or older had hypoglycemia as the first-listed diagnosis and diabetes as another diagnosis. This is new to the Statistics Report.

•    Hyperglycemia: In 2011, about 175,000 emergency room visits for people of all ages had hyperglycemic crisis as the first-listed diagnosis. This is new to the Statistics Report.

•    Hypertension: In 2009–2012, of adults aged 18 years or older with diagnosed diabetes, 71% had blood pressure greater than or equal to 140/90 millimeters of mercury or used prescription medications to lower high blood pressure. This is an increase from 67% in the previous Fact Sheet.

•    Dyslipidemia: In 2009–2012, of adults aged 18 years or older with diagnosed diabetes, 65% had blood LDL cholesterol greater than or equal to 100 mg/dl or used cholesterol-lowering medications. This is new to the Statistics Report.

•    CVD Death Rates: In 2003–2006, after adjusting for population age differences, cardiovascular disease death rates were about 1.7 times higher among adults aged 18 years or older with diagnosed diabetes than among adults without diagnosed diabetes. This data is a change from the previous Fact Sheet, which cited heart disease death rates 2 to 4 times higher for people with vs. without diabetes.

•    Heart Attack Rates: In 2010, after adjusting for population age differences, hospitalization rates for heart attack were 1.8 times higher among adults aged 20 years or older with diagnosed diabetes than among adults without diagnosed diabetes. This is new to the Statistics Report.

•    Stroke: In 2010, after adjusting for population age differences, hospitalization rates for stroke were 1.5 times higher among adults with diagnosed diabetes aged 20 years or older compared to those without diagnosed diabetes. This data is an update and change from the previous Fact Sheet, which rates of stroke 2 to 4 times higher for people with vs. without diabetes.
