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.
