The Midlands and North of England Stillbirth Study
An observational study of Stillbirth, run by University of Manchester at 4 sites in United Kingdom.
Trial summary
The United Kingdom has one of the highest rates of stillbirth in Europe, with more than 4,000 stillbirths every year; which equates to more than 11 deaths every day. Furthermore, this rate has changed very little over the last 20 years. Read more about this study

About this study
Official title: The Midlands and North of England Stillbirth Study - A Case-Control Study of Modifiable Factors in Late Stillbirth
The United Kingdom has one of the highest rates of stillbirth in Europe, with more than 4,000 stillbirths every year; which equates to more than 11 deaths every day. Furthermore, this rate has changed very little over the last 20 years. This loss of life and the adverse psychological consequences urgently needs addressing.
A recent New Zealand study investigating modifiable factors associated with stillbirth (the Auckland Stillbirth Study) found that mothers who did not go to sleep on their left side had a twofold risk of late stillbirth (≥28 weeks gestation) compared to mothers who did go to sleep on their left side. These novel findings need urgent confirmation.

This proposed study aims to confirm or refute these findings and to ascertain whether a preventative programme should be introduced. This proposed study aims to confirm or refute the findings of the Auckland Stillbirth Study.
Participants will be recruited from maternity units in the Midlands and North of England (led by centres in Liverpool, Manchester, West Yorkshire and Birmingham). 291 women with a singleton late stillbirth without congenital abnormality will be interviewed by research midwives shortly after the birth. A control group of 580 women with ongoing pregnancies will be interviewed at a gestation group matched to that at which stillbirths occurred. These data will determine whether an intervention study should be considered. If there is a causal relationship between maternal sleep position and late stillbirth we estimate that upto 37% of late stillbirths might be prevented.
Read the detailed description
The death of an unborn child is a prevalent and tragic public health problem which currently affects millions of families worldwide. Late stillbirth (at or beyond 28 weeks of gestation) is one of the few potentially avoidable maternal and child health problems where the rate of decline in high income countries has slowed in recent decades [1]. The United Kingdom currently has one of the highest rates of stillbirth in Europe, ranking 33rd out of 35 high income countries.
The variations in stillbirth rates between high income countries suggest that it should be possible to make further reductions in late stillbirths. The estimated annual reduction in rates of late stillbirth over recent decades is about 1.1% [1], compared to 2.1% for neonatal death rates, with a resultant increase in the proportion of perinatal deaths (stillbirths plus neonatal deaths) attributable to stillbirth [2]. The Lancet Stillbirth Series [1, 3, 4] has highlighted the silent but prevalent public health problem of stillbirth and together with Sands and the Royal College Of Obstetricians and Gynaecologists has called for research to address these unacceptably high rates.
Current established risk factors for late stillbirth in high income countries include: advanced maternal age (>35 years) [5], high pre-pregnancy body mass index (BMI) [6], smoking [7], reduced antenatal care attendance [8], low socioeconomic status [8] and small for gestational age (SGA) infants [9]. A meta-analysis of population based studies addressing risk factors for stillbirth found that the three most important modifiable risk factors were overweight and obesity (population attributable risk 818%) advanced maternal age (population attributable risk 68%), and smoking (population attributable risk 47%) [3]. Of these only, cigarette smoking may be realistically addressed after pregnancy has started. There has been limited research investigating the role of novel, modifiable factors which have the potential to advance knowledge and address the important gaps in the field of stillbirth research.
This study aims to explore modifiable risk factors for late stillbirth in the UK and to substantiate the recent identification of a new modifiable risk factor for unexpected late pregnancy stillbirths. In the Auckland Stillbirth Study [10] our New Zealand collaborators discovered an approximately two-fold increase in late stillbirth with non-left sided maternal sleep position on the night before the baby died. In addition, women who did not get up at night and those who slept during the day were also at increased risk of stillbirth. The strength of this primary finding was unanticipated and now maternal sleep position requires urgent, rigorous evaluation in another population. MiNESS aims to address these factors.
This multi-centered case control study will recruit 291 women who have experienced a late (≥28 weeks gestation) matched with 580 women who have a continuing pregnancy at the same gestation (controls). The women will be interviewed by an experienced research midwife and an in depth questionnaire will be completed.
Analysis will be carried out using the standard Mantel-Haenszel odds ratio analysis used in case-control studies. Unconditional logistic regression will be used to adjust for potential confounders and to determine the presence of interactions.

Questions about this trial
What is this clinical trial studying?
An observational study of Stillbirth, run by University of Manchester at 4 sites in United Kingdom.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 11 Oct 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 15 Jul 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Maternal Sleep Practices During Pregnancy (time frame: One night prior to questionnaire). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02025530, which also lists 13 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Oct 2019.
