Mothers working to prevent early stillbirth study (MiNESS 20-28): a case-control study protocol.

introductionIn the UK, 1600 babies die every year before, during or immediately after birth at 20-28 weeks' gestation. This bereavement has a similar impact on parental physical and psychological well-being to late stillbirth (>28 weeks' gestation). Improved understanding of potentially modifiable risk factors for late stillbirth (including supine going-to-sleep position) has influenced international clinical practice. Information is now urgently required to similarly inform clinical practice and aid decision-making by expectant mothers/parents, addressing inequalities in pregnancy loss between 20 and 28 weeks. METHODS AND ANALYSIS: This study focuses on what portion of risk of pregnancy loss 20-28 weeks' gestation is associated with exposures amenable to public health campaigns/antenatal care adaptation. A case-control study of non-anomalous singleton baby loss (via miscarriage, stillbirth or early neonatal death) 20 ETHICS AND DISSEMINATION: NHS research ethical approval has been obtained from the London-Seasonal research ethics committee (23/LO/0622). The results will be presented at international conferences and published in peer-reviewed open-access journals. Information from this study will enable development of antenatal care and education for healthcare professionals and pregnant people to reduce risk of early stillbirth. TRIAL REGISTRATION NUMBER: NCT06005272.
