Diabetes is a chronic disease that has been increasing both
at the global and the national level. According to data of
the World Health Organization (WHO) in 2012, it was
found that 1 in 10 of the world’s adult population has diabetes.1
In Thailand, the prevalence of diabetic patients aged 35 years or
above was 9.6%, or about 2.4 million people,2 and the prevalence in
the population aged 15 years and above had increased from 6.7% in
the year 2004 to 6.9% in the year 2009.3-4 Moreover, it was revealed
that people with diabetes are unable to control their blood sugar
level,4 and this causes incidences of complications leading to the
loss of function in various organs such as the eyes, kidneys, heart,
nervous system and blood vessels. The inability to control blood
sugar level is often caused by behavioral problems including eating
an unhealthy diet, lack of exercise, stress and smoking.
