Relationship between maternal serum lipid levels and newborn weight in pregnant women with single positive diabetic screening test / 中国医师进修杂志

ABSTRACT

Objective To investigate the relationship between maternal serum lipid levels and newborn weight in pregnant women with single positive diabetic screening test. Methods On the basis of 75 g oral glucose tolerance test (OGTT), 406 pregnant women during 24-28 gestational week whose 50 glucose challenge test (GCT)≥7.8 mmol/L were separated to gestational diabetes mellitus (GDM) group with 115cases, gestational impaired glucose tolerant (GIGT) group with 60 cases,and GCT (+) group with 231 cases.The serum levels of total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol(LDL-C), apolipoprotein A1 (ApoA1) and apolipoprotein B (ApoB) were measured at the same time. Results Serum TG concentration was significantly higher in GDM group than that in GIGT group and GCT(+) group(P＜0.01).The level of HDL-C, ApoB in GDM group were lower than those in GIGT group and GCT(+) group (P＜0.01). In the 231 women with positive diabetic screening but normal glucose tolerance who delivered at term, the incidence of macrosomia was significantly higher in those with TG levels higher than 3.5 mmol/L (25.0%, 11/44) than in mothers who TG levels were lower than 3.5mmol/L (11.2%, 21/187) (P=0.017). Multiple regression analysis (stepwise) showed that the independent risk factors of macrosomia was the level of TG and ApoB (F=7.677,P=0.006;F = 7.842,P = 0.001 ).Conclusion Among pregnant women with single positive diabetic screening test,maternal serum TG and ApoB are independently associated with neonatal birth weight.
