ONE-THIRD OF U.S. DIABETICS UNDIAGNOSED, STUDY FINDS

June 1, 2006

About one-third of U.S. residents ages 20 and older who have diabetes are undiagnosed, according to a study published in the June issue of Diabetes Care.

Researchers from the U.S. Centers for Disease Control and National Institutes of Health analyzed data on U.S. adults ages 20 and older from 1988-1994 and 1999-2002.

According to the researchers:

  • The rate of diagnosed cases of diabetes increased from 5.1 percent in 1988-1994 to 6.5 percent in 1999-2002.
  • The rate of undiagnosed cases of diabetes remained at about 2.8 percent between 1988-1994 and 1999-2002.
  • The rate of cases of impaired fasting glucose (IFG) -- a prediabetes symptom -- remained at about 26 percent between 1988-1994 and 1999-2002.

Type 2 diabetes accounts for 95 percent of all diabetes cases and almost all undiagnosed cases. Moreover, about 22 percent of adults ages 65 and older have diabetes; about twice as many non-Hispanic blacks have diabetes as non-Hispanic whites.

A second study published in Diabetes Care finds that teenagers with Type 2 diabetes have higher rates of hypertension and early signs of kidney disease than those with Type 1 diabetes. According to study authors, the results indicate that physicians should test teens with Type 2 diabetes for complications.
