Variation in risk factors and timing of birth for different types of preterm birth: A historical cohort study.

ABSTRACT:

Introduction

The aim of this study was to investigate the risk factors and timing of birth for different types of preterm birth, including iatrogenic preterm birth, spontaneous preterm birth, and preterm prelabor rupture of membranes across health services in New South Wales, Australia.

Material and methods

We conducted a historical cohort study between 2018 and 2023 using routinely collected electronic data across four local health districts in New South Wales. Maternal characteristics and outcomes were compared using summary statistics. Differences in the incidence of each preterm birth type were compared using multivariate logistic regression models. Cox regression was performed to assess the time-to-event for each preterm birth type and account for confounders.
