Risk of preterm birth and peripartal complications after first trimester termination of pregnancy: a retrospective cohort study of 35,897 singleton births.

ABSTRACT:

Purpose

The objective of this study was to explore whether a history of termination of pregnancy (TOP) in births after 2015 in a high income setting is still linked to preterm birth (PTB) and peripartal complications.

Methods

35,897 singleton births from a perinatal center with approximately 5000 births per year between 2015 and 2022 were analyzed. Patients with a history of first trimester TOP (TOP < 15 weeks) were compared to those who had never had a TOP. A two-step statistical approach using Chi-squared analysis and forward-step multiple logistic regression was used to explore the relationship.

Results

4132 individuals (11.51%) had a history of first trimester TOP. Our findings suggest an association between past TOP and a higher risk for PTB (OR = 1.44, 95% CI [1
