To evaluate the impact of applying the 2003-ADA-proposed lower normality value of fasting glucose (FG) on impaired fasting glucose (IFG), prevalence and the agreement between diagnostic categories from ADA-2003 FG values and WHO two hours oral glucose tolerance test (OGTT) current criteria in a Mexican population with suspected diabetes.A retrospective cross sectional study was undertaken. We analyzed fasting and 2 hours post load glucose values of 2062 patients and compared diagnostic categories on the basis of different criteria.Considering fasting values, prevalence of IFG changed from 17.7 % to 41.3 % when applying ADA-1997 or ADA-2003 criteria, respectively. Furthermore, based on their OGTT values (WHO-1999), 63 % the 852 IFG patients identified by ADA-2003 criteria were reclassified as having diabetes (26.1 %) or IGT (36.9 %). A heavy kappa test showed a moderate diagonal agreement of 0.43260 (CI 95 % = 0.43214-0.43305) between diagnostic categories from ADA-2003 with FG and OGTT values and WHO current criteria.The lower ADA-2003 criteria for IFG identifies a higher ratio of patients with IGT or DM.
