OBJECTIVE@#To study the influence of
twin pregnancy by
assisted reproductive technology (
ART) versus
twin pregnancy by spontaneous
conception (SC) on neonatal outcomes.@*
METHODS@#A retrospective
analysis was performed for the clinical data of 3 356 live
twins with a
gestational age of ≥24 weeks
who were born in Nanjing
Maternal and Child Health Hospital from 2017 to 2019, with 2 006
twins (1 003 pairs) in the
ART group and 1 350 (675 pairs) in the SC group. The two groups were compared in terms of the
mother's general information and
pregnancy comorbidities and the general information,
diseases, and outcomes of
neonates.@*RESULTS@#Compared with the SC group, the
ART group had a significantly higher
maternal age (@*CONCLUSIONS@#Compared with
twin pregnancy by SC,
twin pregnancy by
ART does not increase the
neonatal mortality rate and
risk of adverse outcomes.
