Objectives: The objective of the study was to assess the performance of the Finnish Diabetic Risk Score (FINDRISC) questionnaire for detecting and predicting risk of type 2 Diabetes mellitus (T2DM) in patients attending a primary health centre. Materials and Methods: We conducted a cross-sectional study comprising 1530 adult participants, age (>20 yrs) attending Outpatient department of a primary health centre located at Harwan, district Srinagar without a diagnosis of T2DM. The risk of developing T2DM was assessed using the validated and widely used FINDRISC. Total Risk Score of each participant was analysed and compared. Results: Data on 1530 participants with unknown diabetes mellitus were analysed.46% of participants were male, and 54% were females. About 55% of participants were literate, 20% were current smokers, 18% had a family history of diabetes mellitus, 15% had a family history of hypertension .48.03% of the study participants have FINDRISC score of less than 7, 28.69% of participants have FINDRISC score between 7-14. Only 3.07% participants have FINDRISC scores of >20. 12% of the participants had a moderate risk for type 2 diabetes of 17% to become diabetic in the next 10 years, and another 10.58% had a high or very high risk of 33-50% to become diabetic in the next 10 years. Conclusion: The FINDRISC questionnaire designed by Finnish diabetic association is a useful screening tool to identify unknown T2DM and estimates the probability of a person to develop diabetes within the next 10 years.
