Investigating maternal risk factors for stillbirth in a population-based cohort in the South of England

IntroductionIn the UK there has been little improvement on the rates of stillbirth; the stillbirth rate was 2.9 per 1000 in 2015 (≥ 28 weeks gestation) and the annual rate reduction (ARR) of stillbirths was 1.4% from 2000–2015, which is roughly in the bottom one-third of high-income countries. Until now, most studies have only identified individual maternal risk factors associated with stillbirth and, to our knowledge, only one study has produced a stillbirth prediction model in the UK. Our study aimed to investigate risk factors for stillbirth (defined as a baby delivered with no signs of life after 24 weeks of pregnancy) using routinely-collected healthcare data at a regional level in the South of England
