Diabetes mellitus (DM) was defined when Fasting Blood Sugar (FBS) was equal or over 126 mg/dl. Data was analyzed by SPSS software, using Chi Square and T.test (P<0.05). Results: The mean age is 44.2 years. FBS of male is 94.51±32.91 mg/dl and of female is 98.2±40.1. The prevalence of diabetes mellitus (DM) is 8.3% [(men = 6.8% and women =9.7%), (urban =10.5% and villages=6.4%0)]. There is a positive correlation between FBS and age, waist circumference and BMI (P=0.01). Blood glucose is controlled by diet and physical activity 64.1% and 24.2%, respectively.
