目的调查北京市昌平区10～18岁超重/肥胖人群空腹血糖受损(IFG)的患病率。方法随机抽样获得样本3409名。体检并记录身高、体重、血压,计算BMI。BMI高于同年龄性别第85百分点者测定空腹血糖。FPG≥5.6 mmol/L者做口服葡萄糖耐量试验(OGTT)。结果空腹血糖筛查发现81例IFG和1例2型糖尿病。超重/肥胖儿童青少年IFG患病率6.12%。OGTT结果显示,除1例2型糖尿病外未发现餐后血糖>7.8 mmol/L者。结论本地区10～18岁超重/肥胖人群IFG患病率较低。

Objective To survey the prevalence of impaired fasting glucose （IFG） in Chinese children and adolescents aged 10 to 18 years in Changping district. Methods In 2007, 9 schools were randomly selected from a total of 84 schools in the Changping district of Beijing. 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 glucoseS5. 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. Conclusion Prevalence of IFG in children and adolescents of Changping district is low.
