Neonatal outcomes
Neonatal outcomes in the study groups are compared in Table 4. The average neonatal birth weight of the late-term group was higher than that of the full-term group (P<0.001), and the macrosomia rate was also significantly higher than that of the full-term group (18% versus 13%, P=0.026). The main difference was in the range of 4000-4499 g (16% versus 12%, P=0.042). Significant differences were not observed in the rates of NICU admission, 1-minute Apgar score ≤7, newborn respiratory distress, subgaleal haemorrhage, glycopenia, neonatal jaundice, swallowing syndrome or clavicle fracture between the two groups. Compared with the full-term group, the late-term group had a higher risk of macrosomia (RR 1.40, 95% CI 1.04-1.88), as shown in Fig. 3.
