Among women with uncomplicated pregnancies, hypoxic composite neonatal morbidity is more common with small-for-gestational-age (SGA) neonates and traumatic-composite neonatal morbidity is more common with large-for-gestational-age (LGA) neonates, a recent study found. The secondary analysis was derived from an observational obstetric cohort of 115,502 deliveries and compared morbidity among SGA, appropriate-for-gestational-age (AGA), and LGA neonates in women with apparently uncomplicated pregnancies at term (≥37 week of gestation). Researchers found:
- Among the 63,436 women who met inclusion criteria, SGA occurred in 7.9% (n=4,983) and LGA in 8.3% (n=5,253).
- Hypoxic composite neonatal morbidity was significantly higher in SGA compared with AGA (1.1% vs 0.7%), but similar between LGA and AGA.
- Traumatic composite neonatal morbidity was significantly higher in LGA vs AGA (1.9% vs 1.0%), but similar in SGA compared with AGA.
