Comparison of metabolic risk profiles between subjects with fasting and 2-hour plasma glucose impairment: The Kinmen Study.
A two-step screening strategy was used to compare the metabolic risk profiles between subjects from Kinmen, Taiwan, who had fasting and 2-hr plasma glucose impairment and were considered at high risk of diabetes due to a fasting plasma glucose (FPG) between 5.6 and 7.8 mmol/l at the baseline screening. 1855 subjects without a previous diagnosis of diabetes who had an FPG of 5.6-7.8 mmol/l at the first step of screening were invited to undergo an Oral Glucose Tolerance Test (OGTT) for the second step of screening, and 1456 of these subjects (774 males and 682 females) completed the OGTT. Subjects who completed the OGTT were classified into normal, isolated impaired fasting glucose (isolated IFG), isolated impaired glucose tolerance (isolated IGT), both IFG and IGT, or undiagnosed diabetes groups. Sex-specific, age-adjusted mean values of metabolic risk profiles for various categories of glucose intolerance were calculated. The results for IFG and IGT agreed in only 20.8% of subjects. The clinical features of subjects with IGT (2-hr glucose impairment) were associated with cardiovascular risk profiles, while those subjects with isolated IFG (fasting glucose impairment only) were not. If the definition of IFG alone had been used for glucose intolerance screening, about 66.6% of subjects with IGT (i.e., isolated IGT with 2-hr glucose impairment and a normal fasting state) who had cardiovascular risk profiles would have been undetected.
