[IP] rise in type 2
(Sept. 4) -- Americans may be overweight, but some of them are lucky. Despite
the substantial proportion of adults with diabetes the number of people
getting the disease is small.
That's the finding by the CDC today -- "unexpected" given the epidemic of
obesity, which can lead to diabetes, the report states.
However, because diabetes develops relatively slowly, statistics in a few
years will likely paint a different picture, points out an accompanying
During the late 1980s and early 1990s, 8.2% of adults had a prediabetes
condition -- or a diabetes diagnosis -- compared with 8.6% in 1999 to 2000.
less than a half a percent increase.
Men and women were affected equally with diabetes. Non-Hispanic blacks and
Mexican Americans were affected disproportionately more than non-Hispanic

7 In 1999-2000, an additional 6% of adults had prediabetes, as did 14% of
adults over age 60. Those numbers are the same as the previous period.
7 Overall, in 1999-2000, an estimated 14% of Americans over age 20 and 34% of
those over age 60 had either diabetes or prediabetes. These estimates fall in
line with previous years.
Because fewer people were included in the 1999-2000 statistics, the report
may be somewhat skewed, the CDC says. Also, a screening test for prediabetes
not performed in 1999-2000, so the true numbers are likely higher.
However, "the findings in this report indicate that the prevalence of
diabetes, either diagnosed or undiagnosed ... did not appear to increase
substantially during the 1990s," the report states. "The apparent lack of
increase ... is
unexpected in light of the increasing prevalence of obesity and overweight in
Future studies will likely show a much clearer picture, reflecting those with
prediabetes -- as well as those who lost weight and made other lifestyle
changes to reduce their risk, as stated in the editorial.
