摘　　要： 目的 探索无追赶生长的小于胎龄儿在儿童期的胰岛素敏感性.方法 收集2008年8月至2016年8月于北京大学第三医院儿科门诊就诊的身材矮小患儿439例,分为小于胎龄儿组(small for gestational age,SGA)218例和特发性矮小组(idiopathic short stature,ISS)221例.比较两组之间的空腹胰岛素、空腹血糖、空腹血糖与胰岛素比值、胰岛β细胞功能(HOMA%)和胰岛素抵抗指数(HOMA-IR)特点.结果 两组患儿均根据青春期分期及性别分组,SGA组与ISS组,青春期前男性患儿的空腹血糖分别为(4.7±0.6)mmol/L和(4.8±0.6)mmol/L,P=0.678,空腹胰岛素(5.1±4.0)mU/L和(4.3±4.7)mU/L,P=0.345,血糖胰岛素比值、HOMA%及HOMA-IR的差异均无统计学意义;青春期前女性患儿的空腹血糖分别为(4.5±0.5)mmol/L和(4.6±0.5)mmol/L,P=0.828,空腹胰岛素分别为(4.7±3.5)mU/L和(4.5±3.3)mU/L,P=0.603,血糖胰岛素比值、HOMA%及HOMA-IR的差异均无统计学意义;青春期男性患儿的空腹血糖分别为(5.0±0.8)mmol/L和(4.9±0.5)mmol/L,P=0.176,空腹胰岛素分别为(5.9±4.3)mU/L和(6.0±4.5)mU/L,P=0.958,血糖胰岛素比值、HOMA%及HOMA-IR的差异均无统计学意义;青春期女性患儿的空腹血糖分别为(4.9±0.6)mmol/L和(4.8±0.4)mmol/L,P=0.141,空腹胰岛素分别为(7.5±6.4)mU/L和(7.4±8.6)mU/L,P=0.448,血糖胰岛素比值、HOMA%及HOMA-IR的差异均无统计学意义. Objective To investigate the insulin sensitivity in children born small for gestational age without catch-up growth.Methods We investigated 439 outpatients in pediatric department of the Third Hospital of Peking University with diagnosis of short stature from August 2008 to August 2016.Two groups were divided based on their diagnosis as born small for gestational age group(SGA)with 218 patients and idiopathic short stature group(ISS)with 221 patients.Fasting blood-glucose,fasting insulin,fasting insulin/fasting blood-glucose,islet beta-cell function(HOMA%),homeostasis model assessment-insulin resistance(HOMA-IR)were analyzed in two groups.Results Hierarchy based on age and sex in SGA and ISS.No significant difference was observed in preadolescent boys with fasting blood-glucose(4.7±0.6 vs 4.8±0.6,P=0.678),fasting insulin(5.1±4.0 vs 4.3±4.7,P=0.345),fasting insulin/fasting blood-glucose,HOMA%,HOMA-IR.No significant difference was observed in preadolescent girls with fasting blood-glucose(4.5±0.5 vs 4.6±0.5,P=0.828),fasting insulin(4.7±3.5 vs 4.5±3.3,P=0.603),fasting insulin/fasting blood-glucose,HOMA%,HOMA-IR.No significant difference was observed in adolescent boys with fasting insulin(5.9±4.3 vs 6.0±4.5,P=0.958),fasting blood-glucose(5.0±0.8 vs 4.9±0.5,P=0.176),fasting insulin/fasting blood-glucose,HOMA%,HOMA-IR.No significant difference was observed in adolescent girls with fasting blood-glucose(4.9±0.6 vs 4.8±0.4,P=0.141),fasting insulin(7.5±6.4 vs 7.4±8.6,P=0.448),fasting insulin/fasting blood-glucose,HOMA%,HOMA-IR.Conclusion The insulin sensitivity were in good condition in children born small for gestational age without catch-up growth.
