[Application and improvement of Chinese Diabetes Risk Score on screening type 2 diabetes mellitus in Wuhai City, Inner Mongolia].

OBJECTIVE: To explore the application and improvement of "Chinese Diabetes Risk Score " on screening type 2 diabetes mellitus in Wuhai City, Inner Mongolia. METHODS: Using multi-stage systematic sampling, 6987 adults were selected to be administered questionnaire and to finish anthropological measurements( height, weight, waist circumference, and blood pressure) and blood tests for fasting plasma glucose and glycosylated hemoglobin. According to Chinese Diabetes Risk Score( DRS-1), some new lifestyle factors associated with diabetes risk were add to the construction of New Diabetes Risk Score( DRS-3). RESULTS: Multi-logistic regression analysis showed a statistically significant positive association between cereals intake and diabetes risk( P <0. 05). In contrast, consumption of fruits was significantly, inversely associated with diabetes risk after adjustment of potential confounders( P < 0. 05). The AUC of the newrisk score( DRS-3), which were constructed by cereals and fruits intake and some other factors, significantly higher when compared with the AUC of the original risk score( DRS-1)( 0. 770 and 0. 783, respectively). The sensitivity and specificity of DRS-1 were 85. 8% and 54. 0% respectively when using the cutoff value recommended( 25 scores). While the sensitivity and specificity of DRS-3 were 85. 5% and 57. 7% respectively when using the optimal cutoff value( 27 scores). CONCLUSION: Chinese Diabetes Risk Score can be used as a primary screening tool for diabetes, and it is necessary to include some lifestyle factors for the improvement of its screening ability.
