Asians are particularly
vulnerable to weight-related health risks, leading medical
experts to recommend that the criteria for overweight and
obesity be adjusted for this group. Such adjustment could
raise the number of overweight and obese people to 1.7 billion
worldwide, a figure that is 50 percent higher than current
estimates.
According to researchers,
the global standard for measuring overweight and obesity,
the Body Mass Index (BMI), is based on western criteria. A
BMI, which takes height and weight into account, of 23 to
24 is considered normal in the west.
However, Asians
have shown a risk of obesity-related diseases such as high
blood pressure, high cholesterol and diabetes if their BMI
is over 23.
Experts suggest
that lowering the BMI scale for Asians will raise doctors’
awareness of potential risks and make it more likely that
they will advise patients to reduce their weight.
Obesity is defined
as a BMI of more than 30, however the area of the body where
excess fat accumulates is important. The accumulation of fat
in the stomach area, known as abdominal obesity, poses more
health risks than fat in the thighs and legs. Abdominal obesity
is a particular problem in Asia.
Experts warned
that the increasing obesity epidemic, which is related to
health risks such as heart disease, diabetes, some cancers
and psychological problems, could overtake that of tobacco.
