Background: Prioritisation of stillbirth research in high-income countries is required to address preventable stillbirth. However, concern is raised by ethics committees, maternity providers and families, when pregnant and bereaved women are approached to participate. Our aim was to 1) assess factors influencing recruitment in a multicentre case-control stillbirth study and 2) gain insight into how women felt about their participation., Methods: Eligible women were contacted through maternity providers from seven New Zealand health regions in 2011-2015. Cases had a recent singleton non-anomalous late stillbirth (≥28 weeks' gestation). Controls were randomly selected and matched for region and gestation. Participants were interviewed by a research midwife and given a feedback form asking their views about participation. Feedback was evaluated using thematic analysis., Results: 169 (66.5%) of 254 eligible cases and 569 (62.2%) of 915 eligible controls were recruited. Non-participants consisted of 263 (22.5% of eligible) women who declined, 108 (9.2% of eligible) uncontactable women, and 60 (5.1% of eligible) women declined by the maternity provider, with no significant differences between the proportion of non-participating cases and controls in each of these three categories. The majority (63.2%) of women did not provide a specific reason for non-participation. Written feedback was provided by 111 participants (cases 15.3%, controls 14.9%) and all described their involvement positively. Feedback themes identified were 'motivation to participate,' 'ease of participation,' and 'post-participation positivity.', Conclusion: Identification of recruitment barriers and our reassuring participant feedback may assist women's participation in future research and support progress towards stillbirth prevention., (Copyright © 2019 The Authors.

Background: For parents who experience stillbirth, knowing the cause of their baby's death is important. A post mortem examination is the gold standard investigation, but little is known about what may influence parents' decisions to accept or decline., Aim: We aimed to identify factors influencing maternal decision-making about post mortem examination after late stillbirth., Methods: In the New Zealand Multicentre Stillbirth Study, 169 women with singleton pregnancies, no known abnormality at recruitment, and late stillbirth (≥28weeks gestation), from seven health regions were interviewed within six weeks of birth. The purpose of this paper was to explore factors related to post mortem examination decision-making and the reasons for declining. We asked women if they would make the same decision again., Results: Maternal decision to decline a post mortem (70/169, 41.4%) was more common among women of Māori (adjusted odds ratio (aOR) 4.99 95% confidence interval (CI) 1.70-14.64) and Pacific (aOR 3.94 95% CI 1.47-10.54) ethnicity compared to European, and parity two or more (aOR 2.95 95% CI 1.14-7.62) compared to primiparous. The main reason for declining was that women 'did not want baby to be cut'. Ten percent (7/70) who declined said they would not make this decision again. No woman who consented regretted her decision., Conclusion: Ethnic differences observed in women's post mortem decision-making should be further explored in future studies. Providing information of the effect of post mortem on the baby's body and the possible emotional benefits of a post mortem may assist women faced with this decision in the future., (© 2018 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.)

Introduction: Accumulating evidence has shown an association between maternal supine going-to-sleep position and stillbirth in late pregnancy. Advising women not to go-to-sleep on their back can potentially reduce late stillbirth rate by 9%. However, the association between maternal right-sided going-to-sleep position and stillbirth is inconsistent across studies. Furthermore, individual studies are underpowered to investigate interactions between maternal going-to-sleep position and fetal vulnerability, which is potentially important for producing clear and tailored public health messages on safe going-to-sleep position. We will use individual participant data (IPD) from existing studies to assess whether right-side and supine going-to-sleep positions are independent risk factors for late stillbirth and to test the interaction between going-to-sleep position and fetal vulnerability., Methods and Analysis: An IPD meta-analysis approach will be used using the Cochrane Collaboration-endorsed methodology. We will identify case-control and prospective cohort studies and randomised trials which collected maternal going-to-sleep position data and pregnancy outcome data that included stillbirth. The primary outcome is stillbirth. A one stage procedure meta-analysis, stratified by study with adjustment of a priori confounders will be carried out., Ethics and Dissemination: The IPD meta-analysis has obtained central ethics approval from the New Zealand Health and Disability Ethics Committee, ref: NTX/06/05/054/AM06. Individual studies should also have ethical approval from relevant local ethics committees. Interpretation of the results will be discussed with consumer representatives. Results of the study will be published in peer-reviewed journals and presented at international conferences., Prospero Registration Number: CRD42017047703., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.
