|Abstract:||Objective. To evaluate normoglycemic overweight/obese (Ow/Ob) children whose post-load plasma glucose (2hPG) cut-point may be significantly associated with cardiometabolic risk factors (CMRFs) and whether this cut-point predicts preclinical signs of organ damage. METHODS: One thousand seven hundred and thrity four normoglycemic Ow/Ob children were stratified into quintiles of 2hPG, the sixth group was constituted by 101 children with impaired glucose tolerance (IGT). RESULTS: Moving from the lower quintiles of 2hPG to IGT, the groups differed for Prepubertal stage, BMI, fasting PG, insulin levels, blood pressure, and lipids. To evaluate the best cut-off of 2hPG related to CMRFs, the area under the receiver operating characteristic curve and the Youden's index was calculated. Insulin resistance, high blood pressure, and high triglyceride/HDL-C ratio were associated with a 2hPG cut-off of 110 mg/dl. Children with 2hPG ≥110 mg/dl showed 1.3-3.2 fold higher risk to have high levels of ALT (as surrogate of nonalcoholic fatty liver disease) or increased carotid intima-media thickness. CONCLUSIONS: This study, performed in a large cohort of Ow/Ob children, shows that an atherogenic risk profile and preclinical signs of organ damage are associated with post-challenge elevations in plasma glucose still considered in the high normal range.|
