Abstract
In the past decade, Diabetes Mellitus tends to become more and more important problem in Thailand.
Nowadays, research results clearly indicate that behavioral change strategies can decrease complications
and death among Diabetes patients. Several studies in China, Finland and USA have reported that intensive behavioral modification program focusing on exercise and weight loss certainly decreases the
risk of Diabetes in high risk group by 31-58 percent. Previous related researches in Thailand have found
that giving knowledge alone have led to negative outcome of Diabetes patient care. This research aimed to
test the effectiveness of intensive behavioral modification program for individual at risk of type 2 diabetes.
This Quasi-experimental research is to study effectiveness of intensive behavioral modification model
which focuses on diet and exercise for 24 weeks. Participants who are overweighed person (BMI > 25 kg/
m2) were divided into two groups. Forty-one participants attended the intensive model while 61 participants
received standard care. Effectiveness of the groups was compared at the end of the study. From data
analysis made through changes of both physical and biochemical indicators, there was no significant
difference found between two groups but subgroup analysis in overweight group (BMI > 30 kg/m2)
indicate that the experimental group significantly lost more weight than control group (95%CI= -1.976 - -
0.019, p-value = 0.046). This finding shows that the program is more suitable for overweight person. However,
long term study is still needed.
