To study the clinical and biochemical profiles across the different ranges of impaired fasting glucose (IFG) based on American Diabetes Association (ADA) and World Health Organization (WHO) criteria. A cross-sectional study was conducted on 149 subjects, of which 63 belonged to group 1 (IFG = 100–110 mg/dl) and 86 to group 2 (IFG = 111–125 mg/dl). Basic anthropometric and clinical examinations were done for all subjects. Data was collected from patient by a questionnaire, which included the history of hypertension and diabetes and other comorbidities and complications. Biochemical profiles including Fasting Plasma Glucose (FPG), Oral Glucose Tolerance Test (OGTT), HbA1c, Fasting insulin levels and Fasting Lipid Profile were measured. Assessment of insulin resistance and beta cell function was done by Homeostasis Model Assessment (HOMA). Data were analysed using SPSS software version 15 and p < 0.05 considered as statistically significant. Family history of diabetes, prevalence of hypertension and higher BMI were noted to be significant higher in group 2 compared to group 1. Clustering of cardiovascular risk factors suggesting metabolic syndrome was also much higher in group 2 (60.5 vs 39.7% p value = 0.012). Impaired glucose tolerance was significantly higher in group 2 (73.3 vs 28.6 p < 0.001) denoting more glycemia. Insulin resistance (HOMA-IR) was significantly higher in group 2 (p = 0.001). Beta cell function (HOMA-β) was also higher in group 2 but not statistically significant (p = 110). In IFG, the higher range of blood sugar 111 to 125 mg/dl is associated with more glycemia, cardiovascular risk factors and insulin resistance. Beta cell function though higher in this group is inadequate to compensate for higher insulin resistance.
