摘要
目的观察超重及肥胖者血浆游离脂肪酸水平与胰岛素抵抗的关系。方法检测57例超重及肥胖者及56例体重正常者三酰甘油(TG)、空腹及口服葡萄糖后2 h之血浆游离脂肪酸浓度,行口服葡萄糖耐量试验(OGTT)及胰岛素释放试验,计算胰岛素敏感指数(ISI)。结果超重及肥胖组血浆游离脂肪酸(FFA)、血糖、三酰甘油(TG)、胰岛素(Ins)水平较对照组升高(P<0.01),FFA与三酰甘油(P<0.01)及血糖、胰岛素水平(P<0.05)呈显著正相关;胰岛素敏感指数(ISI)显著低于对照组(P<0.05),FFA与ISI呈显著负相关(r=-0.364,P<0.01)。结论超重及肥胖者血浆游离脂肪酸浓度升高是引起其产生胰岛素抵抗的重要因素。
