摘要： 目的探讨胎儿生长迟缓(FGR)与新生儿胰岛素敏感性变化的关系。 方法昆明医学院第一附属医院于2004年4~12月，对72例小于胎龄儿(SGA)和48例适于胎龄儿(AGA)空腹血糖(FPG)、空腹胰岛素(FINS)、C肽、HDLC、LDLC、TG、非酯化脂肪酸(NEFA)等指标，计算葡萄糖/胰岛素比值(G/I)、胰岛素敏感性指数(ISI)、胰岛素抵抗指数(HOMAIR)、胰岛β细胞功能(HBCI)等，探讨FGR与新生儿胰岛素敏感性变化的关系。 结果(1)SGA组FPG、HDLC低于AGA组，而FINS、LDLC、TG、NEFA高于AGA组(P<001)；(2)SGA组G/I比值、ISI低于AGA组，HOMAIR高于AGA组(P<001)，而HBCI两组相比差异无显著性(P>005)。 结论FGR儿在生命早期存在胰岛素敏感性降低和不同程度的胰岛素抵抗(IR)，而胰岛β细胞功能无明显变化。

Abstract: AbstractObjectiveTo explore the relationship between fetal growth retardation(FGR)and the change of insulin sensitivity in neonates. MethodsFrom April 2004 to December 2004,72 small for gestational age infants(SGA)and 48 appropriateforgestationalage infants(AGA)were selected in the present study in the First Affiliated Hospital of Kunming Medical College.Fasting plasma glucose(FPG),fasting insulin(FINS),high density lipoproteincholesterol(HDLC),low density lipoproteincholesterol(LDLC),triglyceride(TG) and nonesterified fatty acids(NEFA) were assayed;glucose/insulin ratio (G/I)、insulin sensitivity index(ISI)、insulin resistance index(HOMAIR)，the function of βcell of pancreatic islands(HCBI)，etc.were calculated.Explore the relationship between FGR and the change of insulin sensitivity in neonates. ResultsThe level of FPG and HDLC in SGA group was lower than that in AGA group，but the level of FINS、LDLC、TG and NEFA was higher(P<001).G/I ratio、ISI in SGA group were lower than that in AGA group.HOMAIR was higher(P<001).However，there was no significant difference in HBCI between two groups. ConclusionIn early postnatal life FGR neonates display decreased insulin sensitivity and insulin resistance (IR)to some extent.However，the function of βcell of pancreatic islands has no remarkabe change.
