Students of the 9 schools were stratified according to their age and then randomly selected. We get a sample of 3,409 subjects (1850 boys and 1559 girls). Body weight, the height and blood pressure were measured. The BMI was then calculated. Fasting plasma glucose was measured in the children with a body mass index≥85th percentile. The oral glucose tolerance test (OGTT) was performed in all the subjects with fasting glucose≥5. 6 mmol/L. Results Eighty-one impaired fasting glucose subjects and one girl with type 2 diabetes (T2DM) were identified. The prevalence of IFG in the children and adolescents with overweight/obesity group was 6. 12%. Based on OGTT, 31 of the 81 IFG subjects were proved to have IFG and no postprandial hyperglycemia or IGT was found except for one girl with T2DM.
