The percentage of Americans with diabetes has doubled since 1988, with nearly one in 10 adults now diagnosed with the blood-sugar disease, researchers report.
In the late 1980s and early 1990s, the rate of diagnosed and undiagnosed diabetes was 5.5 percent of the U.S. population. By 2010, that number had risen to 9.3 percent. That means 21 million American adults had confirmed diabetes in 2010, according to the researchers.
Several encouraging findings emerged from the study, however. A smaller proportion of people have undiagnosed diabetes, the report found, suggesting that newer screening techniques may be more efficient.
And the researchers found that overall blood sugar control was improved, although the disease was less well controlled in some minority groups.
