目的根据ＷＨＯ糖尿病诊断和分类委员会近来提出的糖尿病新诊断标准中以空腹血糖（ＦＰＧ）≥７．０ｍｍｏｌ／Ｌ（≥１２６ｍｇ／ｄｌ）取代ＦＰＧ≥７．８ｍｍｏｌ／Ｌ（≥１４０ｍｇ／ｄｌ），为探讨我国糖尿病人群ＦＰＧ的诊断水平。方法对１９９４年全国２５岁以上２５万人群糖尿病普查中经口服７５ｇ葡萄糖耐量试验（ＯＧＴＴ）检查人群的资料进行了分析（其中新诊断２型糖尿病２３８０例、糖耐量低减３１０６例、ＯＧＴＴ正常７７２５例、共１３２１１例）。结果经ＦＰＧ分布频数发现，在新诊断糖尿病组中约５０％的人ＦＰＧ＜７．８ｍｍｏｌ／Ｌ。在该组经直线回归分析显示：与ＯＧＴＴ后２小时静脉血浆血糖（ＰＧ２ｈ）≥１１．１ｍｍｏｌ／Ｌ（≥２００ｍｇ／ｄｌ）相关最好的ＦＰＧ值是≥６．７ｍｍｏｌ／Ｌ（≥１２１ｍｇ／ｄｌ）（Ｐ＜０．０００１）。与ＷＨＯ提出的ＦＰＧ≥７．０ｍｍｏｌ／Ｌ非常接近。经检验ＦＰＧ≥７．０ｍｍｏｌ／Ｌ（≥１２６ｍｇ／ｄｌ）的特异性好于ＦＰＧ≥６．７ｍｍｏｌ／Ｌ（分别为９５％和９１％），敏感性好于ＦＰＧ≥７．８ｍｍｏｌ／Ｌ（分别为６７％和５３％），提示ＦＰＧ≥７．８ｍｍｏｌ／Ｌ不是一个灵敏的诊断指标。在总受检人群组１３２１１例经?
Objective According to the new diagnostic criteria of diabetes newly proposed by the WHO Committee on Diabetes Diagnosis and Classification, FPG≥7.0mmol / L (≥126mg / dl) was substituted for FPG≥7.8mmol / L (≥140mg / dl) To explore the diagnosis of FPG in diabetic population in China. Methods The data of 75 patients with oral glucose tolerance test (OGTT) in the survey of 250 000 population over 25 years of age in China in 1994 were analyzed (including 2380 cases of newly diagnosed type 2 diabetes, 3106 cases of impaired glucose tolerance and 7725 cases of normal OGTT Cases, a total of 13211 cases). Results The frequency of FPG distribution was found in approximately 50% of the newly diagnosed diabetic patients FPG <7.8mmol / L. Linear regression analysis in this group showed that the best FPG value associated with a PG2h of ≥11.1 mmol / L (≥200 mg / dl) at 2 hours after OGTT was ≥ 6.7 mmol / L (≥ 121 mg / dl ) (P <0.0001). And WHO proposed FPG ≥ 7.0mmol / L very close. The test FPG≥7.0mmol / L (≥126mg / dl) specificity is better than FPG≥6.7mmol / L (95% and 91% respectively), the sensitivity is better than FPG≥7.8mmol / L 67% and 53%), suggesting that FPG ≥ 7.8mmol / L is not a sensitive diagnostic indicator. In the total subjects 132 132 cases?
