重庆地区Ezscan用于筛查糖代谢异常的研究

目的：探索Ezscan在无症状人群中筛查糖代谢异常的能力。方法选取2013年8月至2014年8月进行健康体检的重庆市常驻居民1732例，进行问卷调查、体格检查、空腹血糖（FPG）、葡萄糖耐量试验（OGTT）2h血糖、糖化血红蛋白（HbA1c）、血脂和Ezscan检测。结果Ezscan高评分人群糖代谢异常患病率高于低评分人群。Ezscan筛查糖代谢异常的受试者工作特征曲线下面积（AUC）为0．616，最佳切点值为24％，灵敏度为67．0％；FPG筛查糖代谢异常最佳切点值为5．5mmol／L，灵敏度和特异度分别为70．5％和61．7％，AUC为0．824；FPG为6．1mmol／L时，筛查糖代谢异常的灵敏度为47．2％。结论重庆地区Ezscan筛查糖代谢异常灵敏度高于经典方法FPG（切点值为6．1mmol／L）检测，在无症状人群中，Ezscan可作为一种有效的糖代谢异常早期筛查技术。

The study on Ezscan screening for dysglycaemia in Chongqing area

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 .
