Definition Diagnosis and Epidemiology

The diagnosis of diabetes should be made on the basis of a fasting plasma glucose level of 126 mg/dL (7.0 mmol/L) or greater on at least two occasions (Standards, 2005; Halter, 1999). The diagnosis could also be made with an OGTT when the plasma glucose level is higher than 200 mg/mL (11.1 mmol/L) two hours post-challenge (Standards, 2005; Halter, 1999). These criteria have been chosen based on longitudinal studies demonstrating plasma glucose levels associated with an increased risk for retinopathy. Approximately 50% of the elderly population have impaired glucose tolerance (IGT) with normal fasting plasma glucose level. Impaired glucose tolerance (IGT) is defined as a glucose level over 140 mg/dL (7.8 mmol/L), but less than 200 mg/dL (11.1 mmol/L) two hours after a 75 g oral glucose tolerance test (OGTT) (Standards, 2005; Halter, 1999). This is an intermediate stage in the alteration of glucose metabolism and, as such, a strong predictor for the development of type 2 diabetes. The rate of conversion of IGT to diabetes was found to be between 3.6% for women and 8.7% for men per year (Yudkin et al., 1993). Although individuals with IGT do not develop the microvascular complications associated with type 2 diabetes, they are at high risk of developing cardiovascular diseases and are also at higher risk of mortality attributable to cancer (Saydah et al., 2003).
