Abstract
This action research study was aimed at developing a model for the promotion of exercise
behavior in 196 type-2 diabetic patients who were residing in a community of Bang Kor Laem
District, Bangkok. The study population comprised 43 men and 153 women, whose average age was
58.4 ± 9.2 years. The researchers studied the exercise behavior and related data, and measured the
patientsû anthropometry, fasting blood sugar, hemoglobin A1c, and lipid profiles. In this action
research for exercise behavior modification, the Transtheoretical Model (TTM) was employed, and it
yielded successful results; however, when the çFour-step Model for Achievement of Exercise
Behavior Modificationé was applied, it was found that 168 of 189 diabetic patients (equal to 88.9%
of the total) had improved exercise behavior. When comparing the result of blood chemical
concentrations checked before and after the study, it was found that the level of hemoglobin A1c
decreased, with the statistical significance being p = 0.00; however, other factors showed no
statistically significant changes. Based on the results of the study, it was concluded that, after
developing the model for promotion of exercise behavior in type-2 diabetic patients through the
application of the TTM, as well as designing the proper exercise prescription for diabetic patients,
the exercise behavior of the majority of diabetic patients in this program had been successfully
modified.
