Influence of twin pregnancy by assisted reproductive technology on neonatal outcomes / 中国当代儿科杂志

ABSTRACT

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.
