摘要
目的 探讨 1985年WHO与 1997年美国糖尿病学会 (ADA)糖尿病 (DM)诊断标准在老年人群应用中的敏感性及特异性 ,确定在老年人群中诊断DM的理想空腹血糖 (FPG)切点。方法对在北京地区居住 5年以上的老年人群体检时进行口服葡萄糖耐量试验 (OGTT)的 12 0 4人 ,分别根据WHO标准与ADA标准划分不同血糖水平的人群 ,分析其分布的异同 ,并以OGTT 2h血糖 (2hPG)≥ 11.1mmol/L为DM诊断标准 ,分析ADA(FPG)≥ 7.0mmol/L的标准诊断DM的敏感性及特异性变化情况 ,并确定在老年人群中应用FPG诊断DM的理想切点。结果 按WHO标准 (2hPG)诊断DM的患病率为 16 .2 8% ,按ADA标准 (FPG)诊断DM的患病率为 3.16 %。ADA标准制定的FPG 7.0mmol/L所得出的诊断DM的敏感度为 15 .3% ,特异度为 99.2 %。WHO与ADA两项标准均诊断DM的符合率仅为 15 .3% ,糖耐量低减 (IGT)与空腹血糖异常 (IFG)的一致性仅为 4 .5 %。老年人群诊断DM的理想FPG切点为 5 .5mmol/L ,其受性别、年龄、BMI和有否高血压的影响。结论 WHO标准和ADA标准在本人群中缺乏一致性 ,以ADA(FPG)标准诊断老年人群DM时 ,在很大程度上不能替代WHO(2hPG)诊断标准。对 5 .5mmol/L≤FPG <7.0mmol/L老年人群应建议行OGTT检查。
Objective To evaluate the sensitivity and the specificity of WHO and American Diabetes Association (ADA) diagnosis criteria for diabetes mellitus (DM) in senile population and to assess the use of fasting plasma glucose (FPG) alone for the screening of DM as defined by a 2 hour plasma glucose (2hPG)≥11.1 mmol/L during oral 75 g glucose tolerance test (OGTT) and to determine optimal FPG cut point for DM diagnosis. Methods One thousand two hundred and four subjects without DM aged 60 to 90 year, who had resided in Beijing for over 5 years, were recruited, and grouped into different glucose levels by WHO or ADA criteria and analyzed the concordance and the discordance between these subpopulations. The WHO criterion for DM (2hPG≥11.1 mmol/L) was taken as the gold standard. The variations of sensitivity and specificity on ADA criterion for DM (FPG≥7.0 mmol/L) were assessed and determined the optimal FPG cut point in the seniles. Results The prevalence of DM was 3.16% and 16.28% by ADA (FPG) criterion and WHO(2hPG) criterion respectively. The sensitivity of diagnosed DM was 15.3% and the specificity was 99.2% according to ADA criterion. The coincidence percentage under the two criteria was only 15.3%. The coincidence percentage under impaired fasting blood glucose (IFG) and impaired glucose tolerance (IGT) was only 4.5%. The optimal FPG cut point of diagnosed DM was 5.5 mmol/L in the seniles, which was affected by gender, age, body mass index and the presence of hypertension. Conclusion There is lack of concordance between WHO and ADA criteria for DM diagnosis in the seniles. The ADA IFG criterion is not able to replace WHO criterion for DM diagnosis. The senile people with FPG≥5.5 mmol/L but<7.0 mmol/L should receive a standard 75 g OGTT.
