Fetal biometry and maternal characteristics for second trimester prediction of stillbirth.

ABSTRACT:

Introduction

Small fetal size is the most important risk factor for stillbirth. To our knowledge, no previous study has considered combinations of mid-trimester measures of fetal size as predictors of stillbirth risk. The aim of this cohort study was to assess whether small fetal measurements by mid-pregnancy ultrasound, in conjunction with maternal factors, can predict the risk of stillbirth.

Material and methods

In this historical cohort study, we identified 377 563 singleton pregnancies in the Swedish Pregnancy Register between 2014 and 2021, with delivery at ≥22⁺⁰ gestational weeks with a first trimester (6⁺⁰-13⁺⁶ weeks) dating ultrasound, and second trimester (16⁺⁰-21⁺⁶ weeks) measurements of biparietal diameter (BP
