Type 2 Diabetes [T2D] incidence rate is increasing alarmingly among Bangladeshi population. A very few data are available in Bangladesh for T2D disease. The main objectives of this study were to estimate significant risk factors of diabetes mellitus for the Tangail population and develop a valid and nonlaboratory based questionnaire to asses risk of diabetic incidence. Method: A structured questionnaire was administered to 4]] respondents from the Diabetic Care Center of Tangail district. The most significant risk factors were identified using Binomial logistic regression and area under the curve-receiver operating characteristics method [ROC]. The scoring of risk assessment questionnaire was performed and a cut-off score was also determined with suitable specificity/sensitivity ratios. Results: T2D occurred most in the age of ? 45 [69.5%] which made age as the significant risk factor. Other major risk factors are family history or hereditary [p < ] [1], irregular exercise [p =].[42], red meat intake [p < ].]]1], gender [p = ].]33], BMI [p = ].]39], and waist circumference [p = ].]37]. Conclusions: The final score based questionnaire could be a reliable tool for early assessment of type 2 diabetes among Tangail population.
