- Although data were not shown in this study, the OGTT analysis results of 629 individuals who underwent the test at Rumoi Municipal hospital revealed that 82.1% of individuals with FPG <110mg/dl, HOMA-β ≥55 were equivalent to IGT
- In addition, recent epidemiological data in Japan show that subjects with FPG values of 100 to 109mg/dl, which are in the normal range, develop type 2 diabetes at a higher rate than subjects with FPG values <100mg/dl
- Moreover, FPG values of 100 mg/dl are seem to be corresponding to 2-hr values of 140 mg/dl in 75 g OGTT approximately (J. Japan Diab. Soc. 51(3): 281-283, 2008). With those reports as a background, we hypothesized that IGT having insulin resistance was diagnosed when HOMA-IR ≥ 1.4, FPG values of 100-109mg/dl and HOMA-β ≥ 55
- For the purpose of target all subjects exhibited “postprandial hyperglycemia with insulin resistance” within IGT, IFG/IGT and type 2 diabetes, we decided to describe FPG values of ≥100 mg/dl
- Therefore, we hypothesized that individuals who met the criteria of HOMA-IR ≥ 1.4, FPG ≥100 mg/dl, HOMA-β ≥ 55 had postprandial hyperglycemia with insulin resistance
