One-Hour Plasma Glucose Predicts the Progression From Normal Glucose Tolerance to Prediabetes

An increase in 1-h PG concentration precedes the development of prediabetes and identifies individuals with a 1-h PG of 120-155 mg/dL who are at increased risk of developing prediabetes. Therefore, we suggest the term pre-prediabetes for this group with an elevated risk of deteriorating glucose tolerance.
