Methods: The experimental group was provided with the designed planned instruction and modeling in six sessions during 17-week period. The planned instruction and modeling were directed to diabetes self care diet, exercise and drug therapy. Participants of the experimental group had regular educational meetings, discussed and exchanged of information related to glycemic control experiences, demonstration of diabetic foods and exercise. The control group had regular education program. Knowledge and practice were evaluated by questionnaires while glucose control were evaluated by level of fasting blood sugar (FBS) and hemoglobin A₁c (HbA₁c)

Main outcome measures: Pre and Post test about knowledge of diabetes mellitus, practice of diet intake, exercise, drug compliance, level of FBS and HbA₁c in the experimental and the control group.

Results: Knowledge of diabetes mellitus and level of HbA₁c after planned instruction and modeling of the experimental group were significantly improved while knowledge and practice of diet intake, exercise and drug compliance before and after intervention were not different. HbA₁c level after intervention of the experimental group was significantly lower than the control group while knowledge and practice of food intake exercise and drug compliance after intervention were not different.
