New research suggests diabetes is becoming a global problem, with more than 60%
of all cases likely to occur in Asia.
A study in the Journal of the American Medicine Association shows those hit in
Asia are younger and less likely to be overweight than those in the West.
The study says numbers worldwide could grow by a third by 2025, with low and
middle income countries worst hit.
The disease is expensive to treat and could hit Asian economies hard.
The study said trends of diabetes in Asia are influenced by everything from
genetic and cultural differences, to smoking and rates of urbanisation.
Weighty surprise
While in the West, type-2 diabetes is often seen as a consequence of diet, age
and obesity, researchers say those affected in Asia are relatively young and
less likely to be struggling with weight gain.
Citing figures from the International Diabetes Federation, researchers say
while people from Japan to Pakistan generally have lower rates of fat, they can
have a similar or even higher prevalence of diabetes than in the West.
The problem is that although Asian obesity rates are low, changing diets and
sedentary lifestyles, associated with rapid economic development, are taking
their toll.
That transition, which took about 200 years in Europe, has taken just half a
century in Asia, experts noted.
The age differential was also stark. Diabetes most often affects people in the
West at the age of 60 to 79 years, compared to the age range of 20 to 59 years
in Asia.
The study suggested that this appears to be the result of both low birth
weights and over-nutrition in later life, partly because Asian women are two-
to three-times as likely to have gestational diabetes as their white
counterparts.
India will see its numbers grow from 40 million to nearly 70 million; China 39
million to 59 million; and Bangladesh 3.8 million to 7.4 million; the numbers
for Indonesia, the Philippines, Malaysia, Vietnam and others will also rise
dramatically.
The findings were based on analysis of hundreds of articles, data and studies
published between January 1980 and March 2009.
