ABSTRACT
Objective To assess the screening capacity of Ezscan for abnormal glucose metabolism .Methods A total of 1 732 permanent residents of Chongqing city underwent physical examination from August 2013 to August 2014 were selected as subjects ,questionnair survey ,physical examination and Ezscan measurement were performed .Additionally ,the levels of fasting blood‐glucose(FPG) ,OGTT 2h blood glucose ,HbA1c and serum lipid were detected .Results The prevalence rate of abnormal glucose metabolism for residents with high Ezscan score was higher than that in those with low Ezscan score .The AUC of Ezscan screening for abnormal glucose metabolism was 0 .616 ,the optimum diagnosis tangent point was 24 .0% ,the sensitivity was 67 .0% .The optimum diagnosis tangent point of FPG was 5 .5 mmol/L for abnormal glucose metabolism ,the sensitivity and speci‐ficity was 70 .5% and 61 .7% respectively ,and the AUC was 0 .824 .The sensitivity of FPG for screening abnormal glucose metabo‐lism was 47 .2% ,when the cut‐off value of FPG was 6 .1 mmol/L .Conclusion The sensitivity of Ezscan for screening abnormal glucose metabolism is higher than that of FPG (when the cut‐off value was 6 .1 mmol/L) ,Ezscan can be used as an efficiency meth‐od for early detection of abnormal glucose metabolism in the asymptomatic population .
