The analysis of the glycometabolism in the non-catch-up growth children born small for gestational age

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.
