In the lower right corner, there is a
note saying, all rates are presented as comparative rates.
These rates are the prevalence measure.
The point made here is, that there are
major differences between the populations, particularly in regards to
age distributions, which would greatly affect the prevalence, and
the figures have thus been adjusted for such differences.
We'll come back to the role of age later.
The map also shows how many patients of
diabetes in the various parts of the world.
Let's first look at the Norh American and Caribbean region at the upper left.
There are 38 million people out of whom 29% are undiagnosed.
There is a real remark that more health care dollars were spent in this
region than in any other One in ten adults in this region has diabetes.
The prevalence is 10.5%.
In South and Central America there were 26 million, of whom 45.5% went undiagnosed.
And the prevalence were 9.2%.
In the Middle East and North Africa, there were 34 million
with 52.9% undiagnosed and a prevalence of 10.9%.
In Africa, there were 15 million, 81.2% undiagnosed, and a prevalence of 4.3%.
However, as noted, over the next 20 years
the number of people with diabetes will almost double.
This region has a highest mortality rate due to diabetes.
In Europe, which also includes whole Russia, there were 55 million of whom
38.6% where undiagnosed, and the prevalence was 6.7%.
However far the most people with diabetes live in the Far East.
In southeast Asia, including India, 70 million had diabetes, of
whom 51.1% were undiagnosed, and the prevalence was 8.7%.
The greatest contribution came from the
region named Western Pacific, which includes China.
Here, 132 million suffered from diabetes, of whom
57.9% were undiagnosed, and the prevalence was 8%.
Information about the figures for each country is
tabulated here, where you may find your own country.
