Cut‐off values of fasting and post‐load plasma glucose and HbA_1c for predicting Type 2 diabetes in community‐dwelling Japanese subjects: the Hisayama Study

Abstract

Our findings suggest that the cut-off value for predicting Type 2 diabetes in the Japanese population is 5.6 mmol/l (101 mg/dl) for fasting plasma glucose and 37 mmol/mol (5.5%) for HbA(1c), while the 2-h post-load glucose cut-off value is lower than the diagnostic criterion for impaired glucose tolerance.
