Aims/IntroductionElevated 1-h postload plasma glucose concentration (1hPG) during oral glucose tolerance test has been linked to an increased risk of type 2 diabetes and a poorer cardiometabolic risk profile. The present study analyzed the predictability and cut-off point of 1hPG in predicting type 2 diabetes in normal glucose regulation (NGR) subjects, and evaluated the long-term prognosis of NGR subjects with elevated 1hPG in glucose metabolism, kidney function, metabolic states and atherosclerosis. Materials and MethodsA total of 116 Han Chinese classified as NGR in 2002 at the First Affiliated Hospital of Sun Yat-sen University, Guangzhou, Guangdong, China, were investigated. Follow-up was carried out in 2012 to evaluate the progression of glucose metabolism, kidney function, metabolic syndrome and carotid atherosclerosis. ResultsThe areas under receiver operating characteristic curves were higher for 1hPG than FPG or 2hPG (0.858 vs 0.806 vs 0.746). The cut-off value of 1hPG with the maximal sum of sensitivity and specificity in predicting type 2 diabetes in NGR subjects was 8.85mmol/L. The accumulative incidence of type 2 diabetes in subjects with 1hPG 8.85mmol/L was higher than those <8.85mmol/L (46.2% vs 3.3%, P=0.000; relative risk 13.846, 95% confidence interval 4.223-45.400). On follow up, the prevalence of metabolic syndrome and abnormal carotid intima-media thickness in the subjects with 1hPG 8.85mmol/L tended to be higher compared with those <8.85mmol/L. Conclusions1hPG is a good predictor of type 2 diabetes in NGR subjects, and the best cut-off point is 8.85mmol/L. Some tendency indicates that NGR subjects with 1hPG 8.85mmol/L are more prone to metabolic syndrome and carotid atherosclerosis.
