目的了解儿童血糖、血胰岛素与高血压的关系。方法对肥胖儿童及正常对照儿童各６０例进行空腹血糖（ＧＳ）、胰岛素（ＩＳ）及高密度脂蛋白（ＨＤＬ）测定，其中各３０例做葡萄糖耐量试验。结果两组儿童空腹ＧＳ、ＨＤＬ及糖负荷后ＧＳ差异无显著性。肥胖组的空腹ＩＳ、糖负荷后ＩＳ、胰岛素曲线下面积及曲线下面积的ＩＳ／ＧＳ均高于对照组，肥胖组有４３例（７１．７％）血压增高。结论肥胖儿童存在高胰岛素血症及胰岛素抵抗。肥胖与高血压关系密切。 Objective To understand the relationship between blood glucose, blood insulin and hypertension in children. Methods 60 cases of obese children and normal control children were tested for fasting blood glucose (GS), insulin (IS) and high density lipoprotein (HDL), 30 of them were tested for glucose tolerance. Results There was no significant difference in fasting GS, HDL and post-glycemic GS among the two groups. The fasting IS, the post-glycemic load IS, the area under the curve of insulin and the area under the curve of IS / GS in the obese group were all higher than those in the control group. There were 43 cases (71.7%) in the obesity group. Conclusion Obese children have hyperinsulinemia and insulin resistance. Obesity and hypertension are closely related.
