Objective: To identify the incidence of spontaneous preterm birth (SPTB) and indications for delivery in women with twin pregnancy stratified by chorionicity (monochorionic diamniotic and dichorionic diamniotic pregnancy).

Study Design: Multicenter retrospective cohort of all consecutive twin gestations from 2010 to 2017. They were stratified by chorionicity monochorionic diamniotic and dichorionic diamniotic pregnancy: Primary outcome was SPTB < 37 weeks. Secondary outcome was SPTB at <34, 32, and <28 weeks, gestational age at delivery and indications for delivery: maternal and fetal. Analysis: t-test, Fisher’s exact test and multivariable logistic regression.

Results: 510 women with twin pregnancies were identified. 158 (30.9%) were monochorionic diamniotic pregnancies, and 352 (69.0%) were dichorionic pregnancies. The gestational age at delivery was significantly shorter in the monochorionic compared to the dichorionic group of about 2 weeks (MD -2.20 weeks, …
