Assessment of glycohemoglobin, plasma glucose curve and C-reactive protein as complementary predictors to diagnose prediabetes: a transversal study

Results Overall, 26 individuals had prediabetes, 28 did not have prediabetes (22 had 1h-OGTT>fasting glycemia, 6 had 1h-OGTT≤fasting glycemia) and 5 had diabetes. The 1h-OGTT≤fasting glycemia and diabetes groups were excluded, and then a non-parametric test (Mann-Whitney U test) was used to analyze data. There were no statistical differences between 1h-OGTT>fasting glycemia and prediabetes groups in the analysis of glycohemoglobin [5.15 (4.8-5.4); 5.20 (5.10-5.4); p=0.17 ], C-reactive protein [3.70 (1.8-8.9); 3.96 (1.45-7.13); p=0.38], lipids and malondialdehyde, but there were differences in fasting, 30, 60 and 120 min glycemia, insulin level [11(8-13); 13(10-18); p=0.04], Homeostatic Model Assessment-IR [2.45(1.932.95); 3.30(2.51-5.02); p=0.00] and carbonyl protein [0.48 (0.42-0.58); 0.57 (0.5-0.76); p=0.02].
