Objective To explore the influencing factors for macrosomia delivery in puerperae with gestational diabetes mellitus (GDM) versus in puerperae without GDM. Methods A total of 143 puerperae with macrosomia delivery and 157 puerperae with normal birth weight neonates delivery were enrolled as the research subjects, and the former was assigned to GDM macrosomia group or non-GDM macrosomia group, as well as the latter to GDM control group or non-GDM control group according to whether suffering from GDM or not during pregnancy. The multivariate binary Logistic regression model was used to analyze the influencing factors for macrosomia delivery in puerperae with or without GDM. Results With or without GDM, increased pre⁃pregnancy body mass index, elevated apoprotein A level in late pregnancy, and increased cholesterol difference during pregnancy were the risk factors for macrosomia delivery in puerperae (P<0.05), whereas relatively high cholesterol level in late pregnancy was the protective factor for macrosomia delivery in puerperae (P<0.05). In GDM puerperae, high levels of LDL in early pregnancy and pre-OGTT blood glucose in pregnant metaphase were the risk factors for their macrosomia delivery (P<0.05), whereas high HDL difference during pregnancy was the protective factor for their macrosomia delivery (P<0.05). In non-GDM puerperae, male fetus, high total gestational weight gain, great gestational age at delivery, and high LDL level in late pregnancy were the risk factors for their macrosomia delivery, whereas high HDL level in late pregnancy, high LDL difference during pregnancy were the protective factors for their macrosomia delivery (P<0.05). Conclusion The influencing factors for macrosomia delivery are not exactly same between GDM puerperae and non-GDM puerperae. For GDM puerperae, especially for those with high fasting blood glucose, their blood glucose should be appropriately controlled and closely monitored, and blood lipid changes should be paid attention to. For non-GDM puerperae, their body weight management during pregnancy should be paid attention to avoid excessive weight gain, and blood lipid should be monitored to reduce the incidence rate of macrosomia.
